Abstract

The invention concerns a fluid transfer system for transfer of cryogenic hydrocarbon based fluid from a supplying structure to a receiving structure. The fluid transfer system comprises at least one flexible transfer hose for transferring fluid between the supplying structure and the receiving structure, which transfer hose(s) comprises a first hose portion having a first hose end for fluid communicating connection with the supplying structure and a second hose portion having a second hose end for fluid communicating connection with the receiving structure,and where the other of the two ends of the second hose portion is arranged in fluid communication with the end of the first hose portion other than the first hose end,a support structure for supporting the at least one transfer hose, wherein the support structure comprises a column and a support arm, at least one transfer line fixed in one end to a hose end connector unit, which the connector unit is connected in fluid communication with the second hose end, and a first vertical positioning means fixed to the support structure, which vertical positioning means is configured to guide the at least one transfer line in order to, during use, vertically position the second hose end and the hose end connector unit towards a corresponding manifold connector in a second connection assembly arranged at the receiving structure. The support arm is pivotally connected to the column. (Figure 1)

Abstract

The invention concerns arrangements for connection of at least one hose carrying fluid especially LNG and/or vaporized LNG. A hose end (63) of the at least one hose has a hose end connector (91) to be connected to a receiving assembly (90) on a first structure (80) located in water. The hose end connector (91) is provided with guide means (102) and the receiving assembly (90) is provided with receiving means (71). The arrangement includes handling means for controlling the hose end connector (91) to position the guide means (102) into the receiving means (71) and accommodate the guide means (102) in the receiving means (71) so that the guide means (102) is supported in the receiving means (71) and the weight of the hose end connector (91) is transferred to the receiving means (71). The hose end connector (91) has a connecting position with a receiving pipe coupling (15) in the receiving assembly (90), with one receiving pipe coupling (15) provided for each hose end connector (91). The invention also includes methods for connection and disconnection of at least one hose carrying fluid especially LNG and/or vaporized LNG.

Abstract

The invention concerns an arrangement for emergency release of a hose end valve (13) from its connected position with a connector valve (14) which is connected to receiving assembly (90) arranged on a first structure (80) located in water. The hose end valve (13) is provided at a hose end (63) of a hose which carries fluid especially LNG and/or vaporized LNG, and a first end portion of a hose end suspension line (27) is attached to the hose end valve (13), and is suspended in a support structure (200) by at least one line guiding element (31, 28,). A a second end portion of the hose end suspension line (27) is attached to a counterweight (22), wherein the at least one line guiding element (31, 28) is arranged in an elevated position compared to the position of the hose end (63) with the hose end valve (13) and the position of the counterweight (22), thereby providing for a weight balancing relationship. In an emergency release mode the hose end valve (13) is separated from the connector valve (14), and as the weight of the hose end (63) and the hose end valve (13) without the connector valve (14) is smaller than the counterweight (22), the counterweight (22) causes the hose end (63) with the hose end valve (13) to be pulled away from the receiving assembly (90). The invention also concerns a method for emergency release.

Abstract

The invention concerns a traction winch (1) for winching an elongated article (6) having a high-tension end connectable to a load and a low-tension end connectable to a storage device and a method for performing such a winching. The traction winch comprises two or more rotatable drums (2, 3) arranged adjacent to each other with their rotational axes substantially parallel, each of them having a plurality of parallel, circumferential sheaves (4-15) with groove, the sheaves being axially offset with respect to each other to allow wrapping of the elongated article around the sheaves of both drums in a spiral fashion. The sheaves includes fixed sheaves, stationary relative to their underlying drum, and rotatable sheaves, rotatable relative to their underlying drum. The majority of the rotatable sheaves of at least one of the drums is arranged adjacent to each other on a high load supporting side of the winch and the rotational velocity of at least one of the rotatable sheaves is reducible by means of at least one braking device.

Abstract

The invention concerns an apparatus and a method for guiding multi-diameter cables onto a drum (200) by means of a cable guide device. The cable guide device (100) comprising a guiding means (1) translationally moveable along a linear actuator (5), wherein the guiding means (1) has an opening with a minimum spacing (dr) in direction along the orientation of the linear actuator (5) that is larger than the maximum cross-section of the cable (9,9') to be guided inside the guiding means opening, and wherein a cable (9) during use is most of its operational time contacting at least one of at least two barriers (3, 4), which barriers (3, 4) constitute at least part of the confinement of the opening in the orientation of the linear actuator (5). The cable guide is configured to perform sequential steps for each complete winding period to ensure rapid contact recuperation after loss or near loss of cable contact on one or more of the barriers (3, 4).
