Description

[Technical Field]

[0001] The present invention relates to a system and method for mooring a vessel and supplying fluid to the vessel, or for mooring a vessel and supplying fluid and power to the vessel, the system comprising a mooring buoy, a mooring connection comprising a mooring line and a fluid pipe or a mooring line, a fluid pipe and an electrically conductive cable for supplying said power, thereby combining mooring and connection to a power source, and a retractable vessel connector provided at the end of the mooring connection, the vessel connector being a combined mooring connector and fluid connector, or a combined mooring connector, fluid connector and electrical connector, the system further comprising or including a gripping device arranged on the vessel, the gripping device configured to grip and secure said vessel connector and moor the vessel to the mooring buoy. [Background technology]

[0002] Offshore wind turbine installations can be used to power electricity offshore plants that produce a variety of fluid fuels, such as hydrogen and oxygen, through an electrolysis process in which seawater (preferably desalinated seawater) is split into hydrogen and oxygen. Such fluids are useful in that they can be used in fuel cells to produce electricity. The power generated by offshore wind farms can be used for on-site fluid production and storage, especially during periods of wind but low or no power consumption.

[0003] Such fluids produced at an offshore location can be used to power the vessel's propulsion system using the vessel's fuel cells, or to generate electricity to power onboard electrical equipment. In addition, or alternatively, the fluids can be stored in tanks onboard the vessel and transported, for example, to an onshore docking facility that accepts the fluid. In either of these scenarios, the vessel must be in fluid communication with a source of fluid, such as an offshore plant, that provides the fluid, typically for an extended period of time.

[0004] It is well known that anchoring a vessel in an offshore location can be a delicate operation, with seas being either calm or rough, and is even more dangerous when the seas are rough. Anchoring operations can become even more dangerous when there is a transfer of fluids taking place which may be flammable or even explosive in atmospheric conditions.

[0005] In some cases, power and fluids may need to be transmitted / transferred to the vessel, which further complicates anchoring operations.

[0006] While transferring fluids to the vessel, the vessel may be in a waiting area. During such periods, the vessel may still need to power various electrically operated utilities such as air conditioning control, communications, entertainment, lighting, refrigeration, water desalination and treatment, etc. Such power loads are commonly referred to as hotel power.

[0007] A ship typically has two engines, one for propelling the ship and one, often called an auxiliary engine, for providing power to a generator for drive and hotel power; during standby periods, the motor used for propulsion is stopped while the engine driving the generator is running. During such standby periods, the ship is usually anchored, and this anchoring may be assisted by a positioning system that uses electric thrusters to hold the ship in a desired position, for example, with its bow facing the wind and / or waves.

[0008] Although the use of auxiliary engines offers a viable solution, some drawbacks of this solution are excess exhaust emissions and fuel storage taking up storage capacity on the vessel.

[0009] Since the auxiliary engine drives a generator, you may want to explore a solution where the power is supplied from a source external to the vessel that is different from the auxiliary engine driving the generator.

[0010] Such different power sources can be wind turbine power plants, power generating facilities located inland, or even offshore power cables transporting electricity over the sea.

[0011] Furthermore, charging power is also relevant for ships, such as electric ferries, electric cargo ships, and the like, that are partially (hybrid), primarily, or completely powered by electric propulsion means. In this case, power must be provided to charge onboard power storage means, such as batteries, from a power source external to the ship. Charging facilities for such ships can be distributed in strategic geographic locations to ensure charging opportunities within ports or along the ship's travel route between ports. From a logistical perspective, charging facilities for charging batteries can typically be located near shore or at offshore wind turbine plants that utilize generated renewable energy. However, these charging points may also use and be supplied with other power sources.

[0012] It may be desirable to provide power to the vessel from one or more such different sources, but such a connection would require the installation of cable connections on board the vessel to connect to the electrical consumers on board the vessel.

[0013] Therefore, when considering connecting a vessel to a fluid source, or a fluid source together with an external power source, one is faced with the problem of mooring the vessel in a way that does not interfere with the fluid and / or electrical connections (and vice versa). At the same time, the safety of those responsible for the mooring, fluid connections, and electrical connections must be considered. Additionally, typical anchoring techniques can be time-consuming and labor-intensive, and safe, efficient, and fast anchoring would be advantageous.

[0014] Therefore, improved mooring of and fluid connection to a vessel, or improved mooring and fluid and electrical connection to a vessel, would be advantageous, and in particular more efficient and / or reliable fluid connection to a mooring and a vessel, or mooring of a vessel and fluid and electrical connection to a vessel. Summary of the Invention [Problem to be solved by the invention]

[0015] It may be seen as an object of the present invention to provide a mooring of a vessel and a fluid connection therewith, or a mooring of a vessel and a fluid and electrical connection therewith, that solves, in particular, one or more of the problems mentioned above.

[0018] As used herein, mooring preferably refers to the procedure of anchoring a vessel to the seabed or a floating mooring buoy to keep the vessel connected while, for example, delivering fluids or fluids and power. Secure mooring should preferably withstand several forces, such as wind, current, tide, and waves. In preferred embodiments, the strength of the mooring lines and other elements involved in mooring, such as fasteners, anchors, or the like, that secure the mooring lines, is selected to withstand such forces typically encountered during mooring. In preferred embodiments, the mooring lines disclosed herein are configured to take at least a substantial amount of, e.g., all of, the tension resulting from the vessel being moored to the mooring buoy. A substantial amount of tension typically refers to the fact that the mooring of a vessel may include other mooring arrangements, such as additional mooring systems according to preferred embodiments, one or more anchors, and / or mooring buoys in general. All in tension typically refers to the vessel being moored solely by the mooring system of the preferred embodiment, i.e. by single point mooring using mooring buoys.

Such regulations can be IEC / IEEE 80005 and / or DNV-OS-E403 at the date of adoption.

[0021] A "power fluid," also referred to herein as a "fluid," refers to a fluid that possesses energy that can be released in one or more chemical reactions. Non-limiting examples are biogas, natural gas such as liquefied natural gas (LNG), hydrogen, ammonia, nitrogen, oxygen, alkane gases, methanol, ethanol propane, butane gasoline, intermediate fuel oil, synthetic oil, diesel such as marine diesel, and synthetic fuels (electro-fuels). Fluids may be liquefied (if not already liquid under atmospheric conditions) by pressurization and / or cooling. In some preferred embodiments, the power fluid is one or more derivatives of hydrogen, such as ammonia, that can be used as a fuel or in the fertilizer industry.

[0048] Reference is now made to Figure 1, which illustrates a first embodiment of a system for mooring a vessel and providing fluid to the vessel, or for mooring a vessel and providing fluid and power to the vessel. As shown, the system comprises a mooring buoy 1 configured to float on the surface of the ocean and be anchored to the seabed. The mooring buoy 1 is typically anchored to the seabed by an anchor line 34, where the anchor line 34 may be connected to one or more anchoring devices, such as weights of substantial mass, that enable the mooring buoy 1 to maintain a substantially fixed position when a vessel is moored to the buoy 1.

[0049] The system further comprises a mooring connection 2, which in the illustrated embodiment is configured to provide a combined mooring line and connection to a power source. The mooring connection 2 can include a mooring line 3 and a fluid pipe 40 for supplying fluid (gas and / or liquid). Alternatively, the mooring connection can include a mooring line 3, a fluid pipe 40, and an electrically conductive cable 4. These two options are respectively disclosed in FIGS. 1B and 1C, where FIG. 1B shows the fluid pipe 40 and the mooring line 3 in cross section, and FIG. 1C shows the fluid pipe 40, the mooring line 3, and the electrically conductive cable 4 in cross section. It should be noted that FIGS. 1B and 1C should not be construed as being limited to other relative dimensions, for example, the mooring line 3 is dimensioned, inter alia, according to the size of the vessel to be moored.

[0050] In a preferred embodiment, the mooring lines 3 are configured to take at least a substantial amount of the tension force arising from a vessel moored to said mooring buoy 1 using the mooring connections 2, while substantially no mooring tension is applied to the fluid pipes 40 or, if present, the conductive cables 4. In such an embodiment, the remaining amount of tension force arising from the vessel may be taken up by other mooring devices and / or counteracted by a dynamic positioning system.

[0051] In another preferred embodiment, the mooring lines 3 are configured to take all of the tension forces arising from a vessel moored to said mooring buoy 1 using the mooring connections 2, while substantially no mooring tension is applied to the fluid pipes 40 or, if present, the conductive cables 4. Such an embodiment may include a single-point mooring, where the vessel is not moored by use of other mooring devices.

[0052] The preferred embodiment can be configured to moor large and / or small vessels. In a preferred embodiment, the mooring lines 3 are configured to take tensions arising from vessels of more than 50 GT gross tonnage, for example more than 200 GT, preferably more than 500 GT but less than 400,000 GT, preferably less than 300,000 GT gross tonnage, moored to said mooring buoy 1 using the mooring connections 2, while substantially no mooring tensions are applied to the fluid pipes 40 or, if present, the conductive cables 4.

[0053] In a preferred embodiment, the mooring is a single point mooring, in the sense that the vessel is moored solely by an embodiment of the system of the present invention.

[0054] FIG. 1D schematically illustrates an embodiment in which a fluid coupler 41 and a power plug or outlet 12 are provided on the top of the vessel connector. In the embodiment shown, the fluid coupler 41 and the plug or outlet 12 are provided on a protrusion 23, which is described in more detail below. If a conductive cable 4 is not implemented, the plug or outlet 12 is typically omitted. Note that due to the orientation of the view used in FIG. 1D, the mooring line 3 is present but not visible. Additionally, the optional retrieval line 28 has been omitted for greater clarity of illustration.

[0055] In the embodiment shown, the fluid coupling 41 is the female part of the connection and includes a check valve with a ball 42 pressed against a valve seat 43 to prevent fluid from flowing out of the fluid pipe 40 before the valve is opened. In the embodiment shown, the ball 42 is pressed against the valve seat by the fluid in the fluid pipe 40 being at a pressure higher than ambient pressure. The connection also includes a number of spring-activated retainers (four shown) that cooperate with the male part of the connection (not shown). When the male part is inserted into the female part, the spring-activated retainers 44 are pushed back, allowing the male part to move into the female part and move the ball 42 away from the valve seat 43. In this position, the retainers 44 engage recesses in the male part, securing the male part in a position where the valve is opened and fluid can flow toward the vessel. A locking device 45 is provided to prevent the retainers 44 from disengaging. The locking device is configured to move between a position where the retainer 44 cannot move outward and a position as shown where the retainer 44 can move outward to allow the male components to disengage. Appropriate seals are typically provided to make the connection between the male and female components fluid-tight.

[0056] In a preferred embodiment, the fluid pipe 40 is connected to the fluid coupler by suitable fittings (not shown), optionally in combination with heat shrink, welding, or the like, to provide a fluid-tight connection between the fluid pipe 40 and the fluid coupler 41.

[0057] The mooring lines 3 are configured to take tension forces arising from a vessel moored to the mooring buoy 1 using the mooring connections 2, while substantially no mooring tension is applied to the fluid pipes 40 and, if present, the conductive cable 4. The fact that the mooring lines 3 take up such tension forces is typically achieved by the fact that the mooring lines 3, the fluid pipes 40, and the conductive cable 4 are not connected in a way that allows tension forces to be transferred from the mooring lines 3 to the fluid pipes 40 or the conductive cable 4.

[0058] The mooring connection 2 is an elongated element, with the mooring line 3 being connected at one end to the mooring buoy 1 in the embodiment shown. This is perhaps most clearly seen in Figure 5, where the mooring line 3 is connected at one end to the mooring buoy 1 and loops down from the vessel connector 7 to below the mooring buoy 1. The connection of the mooring line 3 to the mooring buoy 1 is made strong enough to withstand forces arising from a vessel moored to the buoy 1 via the mooring line 3. In other embodiments, the mooring line 3 may be anchored to the seabed.

[0059] The system also includes a vessel connector 7 (Figures 1 and 2), which is typically provided at the end of the mooring connection 2. The vessel connector 7 serves at least two purposes: a combined mooring and fluid connector, or a combined mooring, fluid and electrical connector, the mooring connector being used to moor the vessel, the fluid connector being used to supply fluid to the vessel, and the electrical connector being used to supply electricity to the vessel.

[0060] While the present disclosure focuses herein on the supply of fluids, and in some embodiments, power, to vessels, it should be noted that the present invention can also be used to supply fluids or fluids and power using vessels to offshore devices, such as ROVs and other vessels. In addition to supplying fluids or fluids and power, the present invention can also be used to supply signals, such as data signals. While such data can be transmitted using conductive cables, separate data cables, such as optical fiber or conductive cables, can be applied. In such embodiments, the separate data cables are typically integrated into the combined mooring, fluid, and electrical connections.

[0061] A gripping device 13 is arranged on the mooring vessel 14, which is configured to grip and secure the vessel connector 7 and moor the vessel 14 to the mooring buoy 1 (Figures 3A and 3B).

[0062] The fluid pipe 40 is typically made of a flexible material to prevent the fluid pipe 40 from taking on the necessary tension that would otherwise result from the moorings. The fluid pipe 40 can be reinforced with twine or fibers embedded in the flexible material and / or a braid made of twine or fibers can be applied to the fluid pipe 40. This improves the ability of the fluid pipe 40 to withstand increased pressure while still being able to bend due to its flexibility.

[0063] The fluid pipes 40 are preferably provided with a length that allows them to hang freely when the vessel is moored by the mooring lines 3. The fluid pipes 40 exert a towing force on the vessel due to the mass of the fluid pipes 40. However, since the mooring of the vessel is provided by the mooring lines 3, the tow from the moored vessel is substantially taken up by the mooring lines. Thus, mooring can be considered to relate not only to the mooring forces exerted by the vessel itself, but also to the forces exerted by the weight of the fluid pipes 40 and, if present, the weight of the conductive cables 4.

[0064] Thus, in some embodiments, the fluid pipe 40 typically has a length longer than the mooring line 3. The type of fluid and the pressure at which it is delivered determine the sizing and material selection to avoid damage to the fluid pipe 40 during use. As described in more detail below, the fluid pipe extends from a fluid source, which may be an offshore fluid production facility or, for example, a plant / unit for splitting desalinated seawater by electrolysis powered by electricity generated by one or more offshore wind turbines. However, the present invention is not limited to such fluid sources, as the fluid source may also be an onshore fluid production facility, such as a facility for producing biogas. In such situations, the fluid pipe 40 extends from the onshore facility to the mooring system. In a particularly preferred embodiment, the fluid produced and transported is hydrogen.

[0065] The fluid pipe 40 may be fabricated by joining sections of pipe together to form the fluid pipe 40, or may be a continuous fluid pipe. Additionally, the fluid pipe may extend from an offshore electrical distribution device 37' similar to the electrical distribution device 37 disclosed in connection with the conductive cable with reference to Figure 4.

[0066] The conductive cable typically has a longer length than the mooring lines 3 and extends from the power source through the mooring buoy 1. Note that the conductive cable does not necessarily extend uninterrupted from the power source, as the conductive cable may be connected to a power distribution device 37 (see FIG. 4 ) for distributing power to multiple systems for mooring and providing power to the vessel as disclosed herein. In such an embodiment, the power distribution device 37 is connected to a power source. Such a power source may be a wind turbine, such as a wind turbine farm, or any other power source or power generation system. The power source may be located offshore or onshore.

[0067] As shown in Figures 1 and 2, the vessel connector 7 is connected to the mooring line 3 at the end of the mooring connection 2. Note that the mooring connection 2 may extend into the vessel connector 7, as can be seen most clearly in Figure 2.

[0068] To connect the conductive cable to the vessel, the vessel connector 7 includes a power plug and / or outlet 12 to which the conductive cable 4 is electrically connected. The plug and / or outlet 12 is typically located behind a watertight, retractable cover to prevent water from contacting the plug and / or outlet 12.

[0069] In a preferred embodiment, the mooring connection 2 comprises a tubular sheath 15 that surrounds at least a portion of the mooring lines 3, the fluid pipes 40, and, if present, the conductive cables 4. The tubular sheath 15 extends a distance from the vessel connector 7. The tubular sheath 15 is typically dimensioned such that the mooring lines 3, the fluid pipes 40, and, if present, the conductive cables 4 can move more or less freely relative to one another inside the tubular sheath 15, thereby enabling the tubular sheath 15 to act as a protective element for the mooring lines, the fluid pipes 40, and, if present, the conductive cables, while at the same time providing an assembled element for the mooring lines, the fluid pipes, and, if present, the conductive cables, for ease of handling.

[0070] The mooring lines 3 and the conductive cables 4 can be arranged coaxially, with the conductive cables 4 inside the mooring lines 3 (or vice versa). Additionally, the mooring lines 3 and the fluid pipes 40 can be arranged coaxially, with the mooring lines 3 inside the fluid pipes 40 (or vice versa). In such embodiments, it is generally preferred that the conductive cables 4 and the mooring lines 3 be dimensioned relative to one another to allow movement of these two elements relative to one another in their longitudinal direction, at least to prevent the transmission of tension carried by the mooring lines 3 during mooring to the conductive cables 4. In further embodiments, the fluid pipes 40 and the conductive cables 4 can be arranged coaxially inside the mooring lines 3, typically with the conductive cables 4 inside the fluid pipes 40 (or vice versa).

[0071] In another embodiment (see FIG. 2), the mooring lines 3, fluid pipes 40, and, if present, the conductive cables 4, are also arranged side by side, preferably without intertwining and / or interlocking. To provide such a side by side arrangement as an assembled element, the tubular covering 15 disclosed above can be provided (see enlarged cross-sectional views AA, FIGS. 1B-1C).

[0072] Reference is now made to Figures 3A and 3B, which illustrate a particularly preferred embodiment of the gripping device 13. As shown, the gripping device 13 includes a retractable engagement element 16 that is retractable from a first position in which it engages said vessel connector 7 to a second position in which it does not engage said vessel connector 7. In the embodiment shown, the engagement element 16 is configured to reciprocate between the disengaged position shown in Figure 3A and the engaged position with the vessel connector 7. In a preferred embodiment, the disengaged position is a position in which the engagement element 16 is retracted to a lower position, such as towards or even below the level of the vessel deck.

[0073] The gripping device 13 is preferably located at a location on the deck of the vessel, preferably on the open deck, preferably at the bow of the vessel, which is typically the location where the vessel is moored, for example when moored to a quay.

[0074] The alternative engagement element 16 of the gripping device 13 can typically be a chain stopper, a fork, a gripper, a hook with a release function such as a towing hook, or a SMIT bracket, ie a towing bracket.

[0075] 3A and 3B, the system may further include a winch 17 connected to the vessel connector 7 and configured to reel in a rope, cord, cable, wire, or the like, represented in Figures 3A and 3B by a retrieval line 28. The retrieval line 28 is also shown in Figure 1, and its intended use is to first retrieve the retrieval line 28 and then reel in the retrieval line 28 using the winch 17 to lift the vessel connector 7 onto the vessel and into the grasping device. Thus, the winch 17 is preferably positioned relative to the grasping device 13 so as to pull the vessel connector 7 up to the grasping device 13 when reeled in.

[0076] Accordingly, the retrieval line 28 connected to the vessel connector is preferably dimensioned to allow the vessel connector 7 to be hoisted or reeled onto said vessel. Preferably, the retrieval line 28 is positively buoyant and / or is provided with a buoyancy element 29 (see Figure 1) to prevent the retrieval line 28 from completely submerging when the retrieval line 28 is in water.

[0077] 1 , the marine connector 7 has a longitudinal axis 19 along which the marine connector 7 extends, and a proximal end 20 from which the mooring connection 2 extends to a mooring point (e.g., the seabed or a mooring buoy), a fluid source, and, in embodiments including electrically conductive cables, a power source. The marine connector 7 also has a distal end 21 opposite the proximal end 20. In the disclosed embodiment, the outer shape of the marine connector 7 is rotationally symmetrical about the longitudinal axis 19, although the invention is not limited to such symmetrical shapes.

[0078] It is generally preferred to provide positive buoyancy to the vessel connector 7 so that it can float above the ocean surface. Depending on the buoyancy of the mooring lines 3, fluid pipes 40, and, if present, the conductive cables 4, the buoyancy provided to the vessel connector 7 may be sufficient to prevent the mooring lines 3, fluid pipes 40, and / or, if present, the conductive cables 4 from sinking the vessel connector 7. In other embodiments, the mooring lines 3, fluid pipes 40, and / or, if present, the conductive cables 4 may be provided with buoyancy-providing elements.

[0079] The vessel connector 7 includes a narrowed portion 22 spaced from the proximal end 20 and including a protrusion 23 disposed near the distal end 21 of the narrowed portion 22. The narrowed portion 22 is preferably straight with a uniform cross-sectional diameter along the length, although other shapes, such as a tapered shape, can be used. The purpose of the straight narrowed portion 22 in combination with the protrusion 23 is to define an end that can abut one or more elements of the gripping device 13 as the vessel connector 7 is pulled from the mooring line toward the mooring buoy 1. In a preferred embodiment, the narrowed portion 22 can have a degree of flexibility / non-rigidity, which allows this portion of the connector to flex during lifting and mooring operations, for example, when the connector is lifted onto the windward side of a vessel. This can be achieved by making the narrowed portion 22 out of rubber, such as steel-reinforced rubber.

[0080] In the embodiment shown in Figures 3A and 3B, the gripping device 13 includes two prongs 24 sized and shaped to receive the elongated portion 22 while preventing the prongs 23 from passing between them. As shown, the two prongs 24 define a funnel-shaped, open upper portion and a narrower, straight lower portion. The narrower portion can accommodate the elongated portion 22 while the ends of the prongs 23 abut against the prongs 24, preventing the prongs 23 from passing through. This prevents further movement of the marine connector 7 away from the winch 17, which is aligned with the longitudinal axis 19, than defined by the prongs 23. In operation, the marine connector 7 is pulled by the winch 17 toward the gripping device 13, and when the prongs 24 are moved upward as shown in Figure 3B, the prongs 24 are in a retracted position that allows the marine connector 7 to be positioned so that they can grip and engage the marine connector 7.

[0081] After the protrusions 24 engage with the vessel connector 7, the gripping device becomes a tension-retaining element, so that the tension in the recovery line 28 can be released. After the vessel connector 7 is engaged and the tension in the recovery line is released, it is preferable to connect the fluid pipes 40 and, if present, the conductive cables, for supplying fluid and power to the vessel. The advantage of doing this is that it reduces the risk by avoiding workers entering areas where the mooring line is under tension, for example when connecting the fluid pipes 40 and / or the electrical cables 4.

[0082] The gripping device 13 is typically positioned at an elevated position relative to the mooring buoy 1, such that the mooring connection 2 extends diagonally downward from the vessel towards the mooring buoy 1. In addition, the gripping device 13 is typically positioned and dimensioned such that the longitudinal axis 19 of the vessel connector 7 is horizontal, or nearly horizontal, such that any upward forces acting on the vessel connector 7 are normally eliminated, or at least reduced to the extent that it is not necessary to prevent the vessel connector 7 from moving upward within the gripping element 13, thereby allowing the protrusions to move upward to establish the mooring connection.

[0083] The illustrated marine connector 7 has a tapered profile extending from the proximal end 20 to the distal end 21, with the outwardly tapering section 5 having a smallest cross-sectional area at the proximal end 20. By providing the marine connector 7 with such an outwardly tapering profile, the marine connector 7 may exhibit a self-centering function when placed in an opening in a mooring buoy 1. Referring to FIG. 1 , when the marine connector 7 is placed in such an opening 31 in a mooring buoy 1, gravity pulls the marine connector 7 into the opening 31 due to the weight of the mooring connection 2 extending through the opening and the marine connector 7. The opening 31 in the illustrated embodiment has a funnel-shaped top that aids in placing the marine connector 7 into the opening 31.

[0084] In a preferred embodiment, the marine connector 7 includes a shell structure that defines at least the outer shape or outer shell of the marine connector 7. The shell structure is preferably selected to provide a low weight while ensuring sufficient strength to enable the marine connector 7 to undertake mooring forces. Reinforcing elements can be placed inside the shell to improve mechanical strength. The low weight can further provide the marine connector 7 with positive buoyancy that prevents it from sinking if dropped into the sea.

[0085] As shown in Figure 2, the shell structure preferably has an internally located mechanical connection point or connection area 26 to which the mooring line 3 is mechanically connected. In embodiments comprising a conductive cable, an internally located electrical connection point or connection area 27 may be provided to which the cord of the conductive cable 4 is electrically connected. An internal electrical connection is provided between the electrical connection point or connection area 27 and the plug and / or outlet 12.

[0086] The fluid pipe 40 is connected to a fluid coupler (an embodiment of fluid coupler 41 is shown in FIG. 1D ) located inside the vessel connector 7. The fluid coupler 41 is mechanically connected to the vessel connector 7 at a typically internally located mechanical fluid pipe connection point or connection area (which may be the same as for the conductive cable, if present). Such a fluid pipe connection point or connection area is typically designed to be load-bearing, so that the fluid coupler 41 can be released from tension resulting from the weight of the fluid pipe 40 (the fluid coupler 41 is typically located at the end of the fluid pipe 40).

[0087] The marine connector 7 may have an access hatch 25 that provides access from outside the marine connector 7 to an electrical connection point or connection area 27 located therein. Such an arrangement has been found to be practical, for example, when replacing a damaged conductive cable and / or to provide space for manipulating cords inside the marine connector 7.

[0088] Similarly, an access hatch may be provided to provide access to the fluid pipes 40 and the fluid couplers 41. This access hatch may be common to the fluid pipes 40 and the electrical connection points, which may be useful, for example, when replacing or repairing the fluid couplers 41, the fluid pipes 40, or the connections between the fluid pipes 40 and the fluid couplers 41.

[0089] The mooring lines 3 are selected according to the strength and length required to moor the vessel, and non-limiting examples of mooring lines 3 are ropes, cords, cables, wires, or the like.

[0090] Although mooring buoys can be raised from the seabed by other means, the mooring buoy 1 of the preferred embodiment includes a floatable body 30. A floatable body typically means one that floats due to buoyancy, which is the case in the embodiment shown in FIG. 1. As shown in FIG. 1, the floatable body 30 has a vertical through opening 31 when viewed from a position where the mooring buoy 1 is floating on the horizontal sea surface. The vessel connector 7 and the vertical through opening 31 are shaped and dimensioned together to releasably receive at least a portion of the vessel connector 7 in the vertical through opening 31. Releasably received typically means that the vessel connector 7 can be pulled up from its position within the through opening 31. A mooring buoy typically floats whether the vessel connector is retracted into the buoy or when the vessel connector is moored to a vessel.

[0091] As shown in FIG. 1, the upper portion of the through opening may be funnel-shaped 32 having a cross section that decreases downwardly of the vertical through opening 31, which may assist in the location of the vessel connector 7 within the through opening 31, as disclosed above.

[0092] Since the mooring buoy 1 is used to moor a vessel, in some embodiments the mooring buoy 1 is anchored to the seabed. In a preferred embodiment, anchoring is achieved by anchoring the float 30 to the seabed, and for this purpose the float will typically have fastening elements such as fastening holes located on the bottom of the floatable object 30 for securing the anchor line 34 to the floatable object 30.

[0093] Preferably, the proximal end of the mooring line is connected to the floating body of the mooring buoy 1 as described above. In another embodiment, the mooring line can extend through a through opening in the mooring buoy to the seabed or fixed installation and be directly connected there at the proximal end of the mooring line, so that the mooring line also functions as an anchor line.

[0094] In many embodiments, it is preferred that the mooring buoy 1 floats on the sea surface, and therefore the buoyancy of the mooring buoy 1 is preferably greater than the total gravity of the mooring buoy's 1 anchoring chains, cables and the like, and the ship connector 7. Depending on the buoyancy of the mooring lines, the buoyancy of the mooring buoy 1 can also be such that it can withstand the loads of the mooring connection 2.

[0095] The present invention also relates to a method for mooring and supplying fluid or fluid and power to a vessel. In a preferred embodiment, such a method comprises installing a system for mooring and supplying fluid or fluid and power as disclosed herein at an offshore location and anchoring a mooring buoy (1) to the seabed. An offshore location should be understood in a broad context, as it may be closer to shore, such as in a harbor, or may be further away from shore.

[0096] The fluid pipe 40 is fluidly connected to a fluid source. In a preferred embodiment, the fluid source may be an offshore facility that extracts natural gas. In such an embodiment, the fluid pipe 40 is fluidly connected to the offshore facility's natural gas supply to receive extracted gas from the offshore facility.

[0097] In another embodiment, the fluid source is an offshore electrolysis facility to which the fluid pipe 40 is fluidly connected. In the electrolysis facility, seawater is desalinated and split into hydrogen and oxygen by an electrolysis process. Power to operate the desalination and electrolysis is preferably provided by one or more offshore wind turbines. The produced hydrogen is typically stored in suitable storage tanks (fluid source) until it is transferred to a vessel equipped with one or more tanks for storing hydrogen on board. Transfer occurs via the fluid pipe 40. The storage tanks can be located at the site where the hydrogen (or other fluid) is produced and / or in storage tanks included in the mooring buoy 1.

[0098] A system is provided whereby the fluid pipes 40 are connected to a fluid source and, if present, the conductive cables 4 are connected to a power source (not shown). Such fluid and electrical connections can be realised or even re-established before or after the mooring buoy 1 is anchored to the seabed.

[0099] The vessel is navigated to a position adjacent to the offshore location to allow access from the vessel to the vessel connector 7. With the vessel in this position, the vessel connector 7 is hoisted or winched onto the vessel and into the grappling device 13.

[0100] With the vessel connector 7 positioned within the gripping device 13, the gripping device engages and grips the vessel connector 7, and the vessel is then moored. The winch or hauling machine used to pull the vessel connector 7 onto the vessel can now be released. Thus, a single mooring point on the vessel can be achieved by engaging the vessel connector 7 with the on-board gripping device, which takes on all tension forces of the mooring. Such a mooring point is sometimes referred to as a single mooring point, as the vessel connector is gripped and secured by the gripping device, thereby forming a mooring at a single mooring point by the gripping and securing.

[0101] Although the fluid pipes 40, and, if present, the conductive cable, can be connected to supply fluid and power to the vessel virtually any time the vessel connector 7 is in the vicinity of the vessel, it is generally preferred to make the fluid and electrical connections after the vessel connector 7 has been gripped by the gripping device 13. The fluid connection is achieved by connecting the fluid pipes, for example, via the connection shown in FIG. 1D. The electrical connection is achieved by connecting the conductive cable 4 to the vessel's distribution board 36, as shown in FIG. 4, typically using a cable 38 having a plug and / or outlet that connects to the vessel connector 7 and to a plug and / or outlet of the distribution board 36. Such a distribution board 36 is typically configured to distribute power to one or more power-consuming and / or power-storing devices onboard the vessel. It is further preferred that the electrical cable be powered by the power source only when an electrical connection is actually established onboard the vessel. The electrical connector may be rinsed with fresh water to remove salt before connection.

[0102] While it may be preferable that the fluid pipe 40 not be pressurized before being connected to the vessel, this may be impractical, and the present invention covers both situations. On the vessel, the fluid pipe 40 is typically fluidly connected to a fluid inlet on the vessel using flexible tubing that connects with a fluid coupling 41 on the vessel connector 7. The fluid inlet is typically fluidly connected to a storage tank on board the vessel. In embodiments where the fluid is a gas, the gas may be pressurized on board the vessel to improve the vessel's carrying capacity.

[0103] It is generally preferred that the conductive cable be de-energized and electrically disconnectable from the power source by an electrical switch (not shown), particularly to reduce the risk of electric shock during handling of the vessel connector 7 and while establishing electrical connections from the vessel connector 7 on board the vessel. Such an electrical switch may be located in a variety of locations, e.g., at the buoy 1, or remotely, such as at the power source or other locations. The electrical switch may also be located in or on the vessel connector 7. In embodiments where the electrical switch is located remotely from the vessel to prevent manual activation and deactivation, the electrical switch is typically remotely operated. Such remote operation may include transmitting an activation code or a deactivation code (in the case of disconnecting the vessel connector 7) via, for example, the conductive cable, a data cable, SMS, or by wireless transmission. Security, such as an authentication protocol, may be incorporated into the transmission of the codes to avoid unintentional activation and deactivation.

[0104] Fluid flow in the fluid pipe 40 can be activated, for example, by a remotely operated valve, which, as disclosed above, can be actuated by an electrical switch to allow fluid flow.

[0105] Referring to Figure 4, there is shown a schematic representation of typical steps involved in mooring, supplying fluid to vessel 14, and, if a conductive cable is present, supplying power to vessel 14 using the system of the present invention. Note that Figure 4 comprises Figures 4A through 4L, with Figures 4A and 4B showing the vessel approaching mooring buoy 1, Figure 4C showing the mooring buoy 1 floating on the water, and Figure 4D showing optional power distribution equipment 37 distributing power to multiple systems for mooring and supplying power to the vessel. Figures 4E-4L show various stages during mooring and supplying power to vessel 14.

[0106] As perhaps most clearly seen in Figure 4B, a system for mooring, supplying fluid to the vessel, and, if conductive cables are present, supplying power to the vessel, as disclosed elsewhere herein, is located at an offshore location. Mooring buoy 1 is anchored to the seabed using anchoring lines 34.

[0107] Fluid pipes 40 (not shown) are connections to a fluid source, and conductive cable 4 is connected to a power supply (not shown), if present. In the embodiment shown, conductive cable 4 is connected to the power supply via optional power distribution device 37, which has an electrical connection to the power supply, not shown.

[0108] As provided herein, it is generally preferred that the conductive cable is not energized and can be electrically disconnected from the power source by an electrical switch (not shown), particularly to reduce the risk of electric shock during handling of the vessel connector 7 and while establishing electrical connections from the vessel connector 7 on board the vessel.

[0109] To allow access from the vessel 14 to the vessel connector 7 for mooring and fluid or fluid and power supply, the vessel is navigated to a position adjacent to the offshore position of the mooring buoy 1 .

[0110] 4C, such a location is typically one where the retrieval line 28 is in proximity to the vessel 14. If the retrieval line 28 is not implemented, the vessel is typically navigated to a location where the vessel connector 7 is in proximity to the vessel 14 and the retrieval line can be applied to the vessel connector 7. In the following, typical steps involved once the vessel is in position are disclosed.

[0111] As shown in Figure 4E, a deckhand uses a boat hook to pick up the recovery line 28 and bring the recovery line 28 onto the vessel 14 (see Figure 4F). Once the recovery line 28 is on board the vessel, the recovery line 28 is placed on a winch 17 which reels the recovery line 28, hoisting the vessel connector 7 onto the vessel 14 as shown in Figure 4H and onto the grasping device 13. The grasping device shown in Figure 4 is shown in more detail in Figures 3A and 3B.

[0112] With the vessel connector 7 in the gripping device 13, the gripping device engages and grips the vessel connector 7 (as shown in Figure 3B), so that the mooring tension is held by the gripping device 13 and the tension in the retrieval line 28 can be released if necessary, as shown in Figure 4J.

[0113] The fluid pipes 40, and, if present, the conductive cables 4, can now be safely connected to the vessel's fluid inlets and switchboard 36. The fluid inlets are typically configured to direct fluid to one or more storage facilities, such as one or more tanks, and the switchboard 36 is typically configured to distribute electrical power to one or more power consumers and / or storage devices onboard the vessel. The fluid connections are typically made by fluid pipes, and the electrical connections are typically made by cables 38, either of which can be guided from the fluid inlets and / or switchboard 36 to the moored vessel connector 7 by common or separate guides 39. In embodiments where the conductive cables 4 are connected to a power source via an electrical switch, the switch is turned on. For the fluid pipes 40, fluid couplers, such as those detailed in connection with FIG. 1D, automatically open and close to fluid flow when connected and disconnected.

[0114] In embodiments having both conductive cables 4 and fluid pipes 40, only one of fluid and power can be transferred / transmitted at a time. Switching between transferring fluid and transmitting power can be automated, or can be performed by an operator selecting whether to transfer / transmit fluid or power. In automated operation, switching can be initiated based on the required need for fluid or power, the required amount of fluid tank fill, and / or the required state of charge of the battery. Transferring / transmitting only power or only fluid in one operation can improve the safety of the transfer / transmit by at least reducing the possibility of contact between current and fluid at the mooring connection 2.

[0115] In embodiments where only one of fluid and power is transferred / transmitted at a time, this can be done by alternating between transferring fluid and transferring power. Non-transfer / transfer periods can be introduced between the alternation between transferring fluid and transferring power and the alternation between transferring power and transferring fluid. During such non-transfer / transfer periods, neither fluid nor power is transferred / transmitted. Such non-transfer / transfer periods can be used to substantially empty or flush fluid pipes prior to conducting electricity, and / or to discharge static and / or capacitive electricity from conductive cables.

[0116] In a preferred embodiment, the system can include sensors configured to obtain a status of power transmission and / or fluid transfer. Such sensors can include flow rate sensors and sensors configured to detect current or static electricity. Based on sensor measurements from the sensors, fluid transfer can be initiated when the sensor measurements indicate no current or static electricity, and in a preferred embodiment, power transmission can be initiated when the sensor measurements indicate no fluid is being transferred.

[0117] Figure 5 shows some of the steps disclosed in relation to Figure 4 from different perspectives. Figures 5A-5C show a deckhand pulling the recovery line 28 on the vessel. Figure 5C shows the mooring connection 2 being pulled onto the vessel. Figure 5D shows the vessel moored, with the mooring line 3 held taut while the conductive cable 4 hangs loose, i.e., the mooring forces are taken up by the mooring line 3. Similarly, although not shown, the fluid pipe 40 hangs loose and the mooring forces are taken up by the mooring line 3.

[0118] Once the vessel is moored and connections are made, fluid transfer and, if conductive cables are present, power transmission can begin.

[0119] Instead of mooring the vessel connector via a gripping device on the vessel, it is often possible to use the vessel connector solely for fluid supply and, if present, charging purposes, keeping the vessel in a stable position during fluid supply, charging process and power transfer, such as by anchoring, a dynamic positioning system or other means.
