Abstract: The transfer device between a jib including at least one pipe section (54a, 54b) fixed to the jib (12) and a coupling, comprises a system of concertina or deformable diamond-shaped type articulated pipe segments and actuated by cable, at least one pipe section (24a, 24b) connecting to the coupling means. Each section fixed to the jib or connecting to the coupling is connected to one end of the system by a bend and rotary joints (53a, 53b), the bend being fixed to a support (51, 52) suspended from the jib. Each end of the system is fixed to a support (74a) movably mounted in rotation by a bearing (78a) on the bend support to which the end is connected, concentrically with the joint (72a) connecting the end to the bend. The invention applies in particular to the transfer of liquefied natural gas from a marine platform to an oil tanker.

Abstract: An improved double ball valve powered emergency release coupling includes two fluid-carrying conduits, each having a ball or plug valve received therein, which are prevented from being decoupled unless both ball or plug valves are moved to a closed position prior to decoupling. The improved coupling prevents inadvertent spilling during decoupling. A mechanical or hydraulic actuator corresponding to each valve element is provided for sequentially rotating each valve element between opened and closed positions.
