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. |
