Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship technology, and particularly relates to a ship with a ROV system. BACKGROUND

[0002] Some offshore exploration or offshore rescue ships are provided with ROVs on the hulls, and the ROV is a kind of underwater diving equipment that can be used for ocean exploration, search, salvage, underwater operation and rescue.

[0003] Some existing offshore exploration or offshore rescue ships are connected with umbilical cables, and the hulls are provided with a take-up winch and an A-frame crane. The take-up winch is used to take up and release the umbilical cable. The A-frame crane is placed on the ship. When the ship sails to the working water area, the umbilical cable is connected with the ROV after being wound around the pulley of the A-frame crane. The ROV is lifted by the A-frame crane and released to the water surface from the side of the hull. Then the ROV is loosened. The umbilical cable wound on the take-up winch is released by the weight of the ROV. During the process of releasing the umbilical cable, the staff winds a section of the float ball at the position between the pulley and the ROV. Under the action of gravity, the ROV and the umbilical cable can fall to several kilometers deep water for operation (the float ball on the umbilical cable also enters the water when the umbilical cable is lowered). When the buoyancy provided by the float ball body is basically equivalent to the weight of the ROV body and the umbilical cable, the winch continues to release the umbilical cable by a certain length. In this way, the ROV can be remotely controlled to move within a certain range in the deep water. When the ROV is recovered, the take-up winch winds the umbilical cable until the ROV is exposed to the water surface. The staff on the hull gets on the rubber dinghy to approach the ROV and connects the ROV with the A-frame crane on the hull. Then the ROV is lifted to the deck of the hull by the A-frame crane. However, the ship of the prior art has the following disadvantages:

[0004] The ROV is stored on the open deck. For the ship operating in the polar region, the ROV is easily damaged in the low-temperature environment for a long time, which affects the service life. In addition, due to the large size of the ROV, the storage of the ROV on the open deck will affect the arrangement of other equipment and fittings on the open deck. 2. For the ship operating in the polar region, the floating ice in the sea area will collide with the rubber dinghy during the recovery of the ROV, which may damage the rubber dinghy. In addition, the staff needs to get on the rubber dinghy to go to sea. Affected by the wind and waves, the rubber dinghy will shake greatly, which will make the staff have the risk of falling into the sea, and the safety risk is high. SUMMARY

[0030] As Figures 1 to 5As shown, the present application provides a ship with a ROV system, which comprises a ship body 1 and a ROV system. The ROV system comprises a ROV body 2, a floating ball body and a ROV launching and taking-up mechanism. The ship body 1 is provided with an open deck 101, a ROV storage cabin 102 and a moon pool 103 arranged in sequence from top to bottom. The top of the moon pool 103 is provided with a first hatch 1031 communicating with the inside of the ROV storage cabin 102. The bottom of the moon pool 103 is provided with a second hatch 1032 penetrating the outer plate of the ship body 1. The top of the moon pool 103 and the bottom of the moon pool 103 are both provided with a hatch cover 104. The hatch cover 104 on the top of the moon pool 103 selectively seals the first hatch 1031. The hatch cover 104 on the bottom of the moon pool 103 selectively seals the second hatch 1032. The ROV launching and taking-up mechanism comprises a first assembly, a second assembly and a floating ball winding platform 11. The first assembly comprises a first winch 6 and a guide wheel 13 fixed on the top of the ROV storage cabin 102. The guide wheel 13 is opposite to the center of the first hatch 1031. The first winch 6 is wound with an umbilical cable 17. The first winch 6 can take up and release the umbilical cable 17. The guide wheel 13 is provided for the umbilical cable 17. One end of the umbilical cable 17 can be detachably connected with the ROV body 2 by passing through the guide wheel 13. The floating ball body is used for winding the part of the umbilical cable 17 between the guide wheel 13 and the ROV body 2. The second assembly comprises a second winch 7, a trolley 4 and a first guide rail 5. The moon pool 103 is provided with the first guide rail 5. The first guide rail 5 in the moon pool 103 is located between the first hatch 1031 and the second hatch 1032. The first guide rail 5 extends from the first hatch 1031 to the second hatch 1032. In this example, the second winch 7 is installed above the first hatch 1031. The trolley 4 is slidingly arranged on the first guide rail 5. The second winch 7 is detachably connected with the trolley 4 through a first cable 18. A locking assembly 9 is arranged between the trolley 4 and the ROV body 2. The locking assembly 9 can lock the ROV body 2 and the trolley 4. Specifically, the locking assembly 9 comprises a lock seat 901, a controller (not shown in the figure) and a remote control lock head 902 which can be locked in the lock seat 901. One of the lock seat 901 and the remote control lock head 902 is installed on the ROV body 2, and the other is installed on the trolley 4. The controller is in communication connection with the remote control lock head 902. The remote control lock head 902 can be locked or unlocked with the lock seat 901 by the controller. The floating ball winding platform 11 is rotatably arranged on the inner side wall of the ROV storage cabin 102. The floating ball winding platform 11 rotates relative to the inner side wall of the ROV storage cabin 102, so as to switch the floating ball winding platform 11 between a storage position and a deployment position. When the floating ball winding platform 11 is in the deployment position, the floating ball winding platform 11 is parallel to the bottom of the ROV storage cabin and extends in the horizontal direction. The floating ball winding platform 11 at least partially protrudes from the first hatch 1031. When the floating ball winding platform 11 is in the storage position, the floating ball winding platform 11 is perpendicular to the bottom of the ROV storage cabin, so as to move the floating ball winding platform to the side of the first hatch 1031.

[0031] The ROV storage cabin 102 is arranged below the open deck 101. When the ROV body 2 is not used, the ROV body 2 can be stored in the ROV storage cabin 102, so that the ROV body 2 is not exposed to the air, the ROV body 2 is protected, the ROV body 2 does not occupy the space on the open deck 101, the installation of the fittings on the open deck 101 is facilitated, and the space utilization on the open deck 101 is facilitated. Through the cooperation of the first assembly and the second assembly, the ROV body 2 can be launched from the first hatch 1031 into the moon pool 103 and launched from the moon pool 103 into the seawater through the second hatch 1032, so that the launching of the ROV body 2 is realized. Before the ROV body 2 enters the moon pool 103, the hatch cover 104 of the second hatch 1032 is opened, and water is injected into the moon pool 103, so that the water level in the moon pool 103 is flush with the water level of the ship body 1. The guide wheel 13 is arranged at the top of the ROV storage cabin and is located at a position directly opposite the center of the first hatch 1031. One end of the umbilical cable 17 released from the first winch 6 passes through the guide wheel 13 and is detachably connected with the ROV body 2. The cooperation of the umbilical cable 17, the guide wheel 13 and the first winch 6 can lower the ROV body 2 from the first hatch 1031 to the trolley 4 in the moon pool 103. The locking assembly 9 locks the ROV body 2 on the trolley 4. After the first cable 18 is connected with the ROV body 2, the first winch 6 and the second winch 7 work synchronously, so that the umbilical cable 17 and the first cable 18 are synchronously released. The trolley 4 slides from the first hatch 1031 towards the second hatch 1032, and the ROV body 2 moves towards the bottom of the moon pool 103. When the trolley 4 moves the ROV body 2 into the seawater in the moon pool 103, the locking assembly 9 releases the locking of the ROV body 2 and the trolley 4, so that the ROV body 2 is separated from the trolley 4. At this time, the ROV body 2 can be navigated from the second hatch 1032 to the operation area through the remote controller, so that the launching of the ROV body 2 is realized. When the ROV body 2 needs to be retrieved, the ROV body 2 is controlled to enter the moon pool 103 from the second hatch 1032 through the remote controller, and the ROV body 2 is close to the trolley 4. The locking assembly 9 is used to lock the ROV body 2 on the trolley 4. The second winch 7 winds the first cable 18, so that the trolley 4 moves along the first guide rail 5 towards the first hatch 1031. In this process, the first winch 6 also winds the umbilical cable 17. When the trolley 4 moves to the first hatch 1031, the locking assembly 9 releases the locking of the ROV body 2 and the trolley 4. The first winch 6 lifts the ROV body 2 through the umbilical cable 17 and moves the ROV body 2 out of the first hatch 1031 into the ROV storage cabin 102, so that the retrieval of the ROV body 2 is realized, and the safety of the launching and retrieving of the ROV body is improved.In the ship, the guide wheel 13 is arranged at the center of the ROV storage cabin 102 for the first hatch 1031, and during the process of hoisting the ROV body 2 by the umbilical cable 17, the center of gravity of the ROV body 2 is kept at the center of the first hatch 1031, so as to prevent the ROV body 2 from colliding with the edge position of the first hatch 1031. In addition, during the process of launching the ROV body 2, the first winch 6 continuously releases the umbilical cable 17, and the rotatable floating ball winding table 11 is arranged on the inner side wall of the ROV storage cabin 102. The floating ball winding table 11 is rotated to the unfolded position, so that the worker can walk to the position directly above the first hatch 1031 through the floating ball winding table 11 to conveniently wind the floating ball body on the part of the umbilical cable 17 between the guide wheel 13 and the ROV body 2. Since the umbilical cable 17 may collide with the floating ball winding table 11 when the ROV body 2 is working in the sea and drives the umbilical cable 17 to sway in the first hatch 1031, the floating ball winding table 11 is rotated to the storage position after the floating ball body is wound, so that the floating ball winding table 11 is moved to one side of the first hatch 1031, thereby avoiding the risk of damage to the umbilical cable 17 caused by the collision between the umbilical cable 17 and the floating ball winding table 11, and facilitating the launching and recovery of the ROV body.

[0032] The ROV launching and recovering mechanism further comprises a third winch 8 fixed on the inner side wall of the ROV storage cabin 102, and a second cable 19 is wound on the third winch 8. The part of the second cable 19 extending out of the third winch 8 is connected with the floating ball winding table 11. The inner side wall of the ROV storage cabin 102 is protrusively provided with a fixing table 14, and the floating ball winding table 11 is hinged to the fixing table 14 through a hinge part. The fixing table 14 provides a mounting space for the floating ball winding table 11, so as to facilitate the installation of the floating ball winding table 11. When the third winch 8 releases the second cable 19, the floating ball winding table 11 will automatically rotate from the storage position to the unfolded position under the action of gravity. When the third winch 8 winds the second cable 19, the tightening of the second cable 19 drives the floating ball winding table 11 to rotate from the unfolded position to the storage position.

[0033] Specifically, the side wall of the ROV storage cabin 102 is protrusively provided with a boss 15, and the third winch 8 is installed on the boss 15.

[0034] In order to improve the safety during winding the floating ball, a protective fence 12 is arranged on the edge of the floating ball winding table 11, so as to prevent the worker from falling off the floating ball winding table 11.

[0035] In the embodiment, the hull 1 is further provided with an equipment cabin 105, which is located below the ROV storage cabin 102 and horizontally beside the moon pool 103. The first winch 6 is arranged in the equipment cabin 105. The bottom of the ROV storage cabin 102 is provided with a cable passing hole 105, which is in communication with the equipment cabin 105. The umbilical cable 17 of the first winch 6 extends to the inside of the ROV storage cabin 102 through the cable passing hole 105. In actual implementation, the equipment cabin 105 can be provided with other equipment besides the first winch 6, so as to reduce the arrangement of equipment on the open deck 101.

[0036] In a preferred embodiment, the ROV system further comprises an ROV transfer mechanism. The side wall of the ROV storage cabin 102 is provided with a lifting opening (not shown in the figure) for lifting the ROV body 2. The ROV transfer mechanism comprises a second guide rail 10 arranged at the bottom of the ROV storage cabin 102 and a transfer trolley 16 movable on the second guide rail 10. The second guide rail 10 extends from the lifting opening to the first hatch 1031. The transfer trolley 16 is used to transfer the ROV body 2. In actual implementation, the ROV body 2 needs to be lifted from the shore by a lifting device such as a crane and then lifted into the ROV storage cabin 102 for subsequent use. In the embodiment, the lifting opening is arranged on the side wall of the ROV storage cabin 102. The ROV body 2 can be lifted from the lifting opening to the transfer trolley 16 inside the ROV storage cabin 102. The transfer trolley 16 moves on the second guide rail 10 to transfer the ROV body 2 to the first hatch 1031. Thus, the transfer of the ROV body 2 is greatly facilitated.

[0037] Specifically, the ROV storage cabin 102 comprises a first cabin 1021 and a second cabin 1022, the first cabin 1021 and the second cabin 1022 are communicated through a communication port, a first hatch 1031 is arranged on the bottom of the first cabin 1021, the guide wheel 13, the floating ball winding table 11 and the second winch 7 are arranged in the first cabin 1021, a lifting port is arranged on the side wall of the second cabin 1022, the second guide rail 10 extends from the second cabin 1022 to the first cabin 1021 through the communication port, the second cabin 1022 is used for storing the ROV body 2 to be launched, and a heater is arranged in the second cabin 1022. In actual implementation, the ROV body 2 is first lifted to the ship body 1, and then the ship body 1 sails to the working water area, and then the ROV body 2 on the ship body 1 is launched into the seawater in the working area. In the embodiment, the first cabin 1021 and the second cabin 1022 are arranged in the ROV storage cabin 102, when the ROV body 2 is not needed, the ROV body 2 can be stored in the second cabin 1022, and when the ship body 1 sails in the ice area, since the heater is arranged in the second cabin 1022, the temperature in the second cabin 1022 can be raised through the heating of the heater, thereby avoiding the risk that the ROV body 2 is damaged due to long-time stay in the low-temperature environment. In addition, before the ROV body 2 is launched into the seawater, the ROV body 2 usually needs to be overhauled, the heater is used to heat the inside of the second cabin 1022, the temperature in the second cabin 1022 is raised, and this is beneficial to the overhauling work of the ROV body 2 by the workers in the second cabin 1022. When the ROV body 2 needs to be used, the ROV body 2 is transferred to the first cabin 1021 through the transfer trolley 16, and the ROV body 2 is launched in the first cabin 1021.

[0038] When the ROV body 2 is transferred, in order to prevent the ROV body 2 from sliding off the transfer trolley 16, a fixing component (for example, a fixing rope) needs to be used to fix the ROV body 2 on the transfer trolley 16 when the transfer trolley 16 transfers the ROV body 2.

[0039] Specifically, the first cabin 1021 is provided with a first cabin door 3, the first cabin door 3 is used to cover the communication port, the second cabin 1022 is provided with a second cabin door, the second cabin door is used to cover the lifting port, the first cabin door 3 is arranged to cover the communication port, and the second cabin door is arranged to cover the lifting port, so that the heat in the second cabin 1022 can be prevented from being dissipated from the communication port and the lifting port, and when the transfer trolley 16 passes through the communication port, the first cabin door 3 is opened to enable the ROV body 2 to enter the first cabin 1021 from the second cabin 1022.

[0040] Preferably, when the first cabin 1021 is provided with the first cabin door 3, the first cabin door 3 is a roller shutter door, which is convenient for covering and opening the communication port. Of course, in the example, the specific type of the first cabin door 3 can also be arranged according to the needs, and the specific type of the first cabin door 3 is not limited herein.

[0041] In one embodiment, the second guide rail 10 is arranged to cross the first hatch 1031, and the part of the second guide rail 10 crossing the first hatch 1031 is detachably connected to the bottom of the first cabin 1021. The first cable 18 has two connection ends on one end thereof, one of which is used to be detachably connected to the ROV body 2, and the other is used to be detachably connected to the trolley 4. In actual implementation, the transfer trolley 16 moves the ROV body 2 along the extension direction of the second guide rail 10, and when the transfer trolley 16 transfers the ROV body 2 to the position where the second guide rail 10 faces the first hatch 1031, the umbilical cable 17 and one of the connection ends of the first cable 18 are connected to the ROV body 2, the first winch 6 and the second winch 7 are synchronously operated, the ROV body 2 is lifted upward by about 0.3 m through the umbilical cable 17 and the first cable 18, then the transfer trolley 16 is moved away from above the first hatch 1031, the part of the second guide rail 10 crossing the first hatch 1031 is removed, and then the hatch cover 104 of the first hatch 1031 is opened, the ROV body 2 is launched onto the trolley 4 through the umbilical cable 17 and the first cable 18, the other end of the first cable 18 is connected to the trolley 4, and the first winch 6 and the second winch 7 continue to be synchronously operated to lower the ROV body 2 to the bottom of the moon pool 103 through the trolley 4.

[0042] In another embodiment, the umbilical cable 17 can be used to lift the ROV body 2 upward by about 0.3 m from the transfer trolley 16, that is, the first cable 18 can also have only one connection end.

[0043] In a preferred embodiment, the first winch 6 and the second winch 7 each include a cable storage winch 22, a compensation unit 23 and a traction winch 24. The cable storage winch 22, the compensation unit 23 and the traction winch 24 of the first winch 6 are arranged in sequence along the outgoing direction of the umbilical cable 17, and the cable storage winch 22, the compensation unit 23 and the traction winch 24 of the second winch 7 are arranged in sequence along the outgoing direction of the first cable 18. A wire guide wheel 26 is arranged between the compensation unit 23 and the traction winch 24. Through the cooperation of the cable storage winch 22, the compensation unit 23 and the traction winch 24, the tension of the umbilical cable 17 and the first cable 18 is fixed during the launching of the ROV body 2 onto the moon pool 103 through the trolley 4, so as to ensure that the trolley 4 maintains a horizontal state during the sliding process of the trolley 4 on the first guide rail 5, avoids the pulley of the trolley 4 from being stuck in the first guide rail 5, and avoids the excess of the umbilical cable 17 from being wound on other equipment inside the moon pool 103 or the first cabin 1021 to affect the launching of the ROV.

[0044] In an embodiment, the ship body 1 is further provided with a seawater discharging mechanism and a seawater pumping mechanism. The seawater discharging mechanism comprises a first seawater pump 20, a first water inlet pipe (not shown in the figure) and a first water outlet pipe (not shown in the figure). The first seawater pump 20 is used to pump seawater in the moon pool 103 out of the ship body 1. The seawater pumping mechanism comprises a second seawater pump 21, a second water inlet pipe (not shown in the figure) and a second water outlet pipe (not shown in the figure). The second seawater pump 21 is used to pump seawater into the moon pool 103. The first seawater pump 20 and the second seawater pump 21 are both installed in the equipment cabin 105. The water inlet of the first seawater pump 20 is connected to the inside of the moon pool 103 through the first water inlet pipe. The water outlet of the first seawater pump 20 is connected to the outside of the ship body 1 through the first water outlet pipe. The water outlet of the second seawater pump 21 is connected to the inside of the moon pool 103 through the second water outlet pipe. The water inlet of the second seawater pump 21 is connected to seawater outside the ship body 1 through the second water inlet pipe. In actual implementation, after the ship body 1 sails to the working area, the second seawater pump 21 is started to pump seawater from the outside into the moon pool 103. When the water level in the moon pool 103 is level with the waterline of the ship body 1, the hatch 104 at the bottom of the moon pool 103 is opened, so that the moon pool 103 can be connected to the outside of the ship body 1 through the second hatch 1032. When the hatch 104 on the first hatch 1031 is also opened, the ROV body 2 can be launched into seawater from the moon pool 103 and the second hatch 1032 through the open deck 101. After the ROV body 2 is used, the ROV body 2 is recovered into the ROV storage cabin 102 from the second hatch 1032 and the moon pool 103. After the ROV body 2 is recovered, the hatch 104 of the second hatch 1032 is closed, and the bottom of the moon pool 103 is sealed through the second hatch 1032. Then the first seawater pump 20 is started to pump the seawater remaining in the moon pool 103 out of the ship body 1.

[0045] It can be understood that when the ship body 1 sails in the ice area, the sealing position of the hatch cover 104 at the bottom of the moon pool 103 and the second hatch 1032 is prone to icing due to the low temperature in the ice area, and the hatch cover 104 cannot be smoothly opened. To this end, the ship body 1 is also provided with a deicing mechanism. The deicing mechanism includes a hot water pipe, one end of the hot water pipe is in communication with the water outlet end of the cooling system on the ship body 1, and the other end of the hot water output pipe is in communication with the inside of the moon pool 103. It can be understood that the cooling system on the ship body 1 is used to cool the main engine of the ship, and the cooling system is a common heat dissipation component on the ship body 1. The cooling system in the prior art has a water cooling pipe. The cold water is input into the water cooling pipe to absorb the heat of the main engine, and then discharged from the side of the ship body 1 to the sea water. In the present embodiment, the hot water discharged from the cooling system is input into the moon pool 103 through the hot water pipe. The hot water enters the moon pool 103 to soak the sealing connection position of the second hatch 1032 and the hatch cover 104. In this way, the ice condensed on the sealing position of the second hatch 1032 and the hatch cover 104 can be melted by the hot water, so that the hatch cover 104 of the second hatch 1032 can be smoothly opened.

[0046] In actual implementation, hot water is continuously input into the moon pool 103 through the hot water pipe several hours before the hatch cover 104 of the second hatch 1032 needs to be opened.

[0047] In actual implementation, in order to prevent ice blocks in the sea water from being sucked into the moon pool 103, a sea water valve box is arranged at the bottom of the ship body 1. The sea water valve box has a water suction port in communication with the outside of the ship body 1. A filter is arranged at the water suction port. The water suction port is in communication with the second water inlet pipe through the filter. Since the sea water valve box is located at the bottom of the ship body 1 and extends into the sea water to a certain depth, ice blocks floating on the sea surface are not easy to be sucked into the moon pool 103. In addition, the water suction port is in communication with the second water inlet pipe through the filter. The filter can also filter floating ice, reducing the risk of entering the second sea water pump 21.
