Embodiment Construction

[0049] first reference figure 1 , schematically shows the general layout of the assembly for transferring fluid according to the present invention. figure 1 It is merely used to clarify the positional relationship between the constituent parts of the assembly and is not used to give specific details regarding constructional details or dimensions.

[0050] The assembly for transferring fluid basically includes a first vessel 1 , a second vessel 2 and a third vessel 3 . The first vessel 1 comprises, for example, an FPSO, which can be moored to the seabed by means of known assemblies of turrets 4 by means of mooring lines 6 in a windward manner. A production line or riser 7 (eg for oil or gas) enters the vessel 1 via buoys 5 and turret 4 and is connected (in a well known manner and not specifically shown here) to pipelines or other equipment on the first vessel 1 .

[0051] It should be noted that other mooring concepts can also be used for the first vessel 1, such as multi-po...

Abstract

A method for transferring fluids between a first vessel (1) and a second vessel (2), comprises a step of establishing a direct mooring connection between the first (1) and second (2) vessels using a mooring line (8), a step of positioning and maintaining a third vessel (3) closer to the second vessel (2) than to the first vessel (1), a step of providing a first fluid transfer hose (9) and connecting it with a first end (10) to a fluid outlet (11) on the first vessel (1) and with a second end (12) to an intermediate fluid inlet (13) at the third vessel (3), a step of providing a second fluid transfer hose (14) and connecting it with a first end (15) to an intermediate fluid outlet (16) at the third vessel (3) and with a second end (16) to a fluid inlet (17) on the second vessel (2) and a step of establishing a fluid communication between the intermediate fluid inlet (13) and intermediate fluid outlet (16).

Description

technical field [0001] The invention relates in a first aspect to a method for transferring fluid between a first vessel and a second vessel. Background technique [0002] The main field of application of such methods is the offshore production of oil and gas. The first vessel may eg comprise a so-called FPSO (Floating Production Storage Offloading vessel), from which oil or natural gas (such as LNG) has to be transferred to a tanker. Known methods use floating fluid transfer hoses connecting a first vessel to a second vessel. A disadvantage of such an approach is that its use is limited to environments with moderate sea states (significant wave heights of up to 2-3 metres). For higher sea conditions, the forces generated by floating fluid transfer hoses reach levels that exceed the design values ​​of the tanker's hose handling system. Such tankers are usually equipped with amidships manifolds to which the fluid transfer hoses must be connected and such manifolds cannot c...
