Abstract: Device for controlling the movement of one of the ends of an articulated fluid loading arm from a storage position to a target pipe (35) and from this target pipe (35) to the storage position, said arm comprising a fluid transfer line equipped at this end with a coupling system (26), the latter being adapted to be coupled to the target pipe (35) for the transfer of the fluid, which device comprises actuators (27-29) for controlling the movement of the arm in space from the storage position until the coupling system (26) is positioned in front of the target pipe (35) for its coupling to the latter, and from the target pipe (35) to the storage position.

Abstract: Bow loading system to be installed on a forecastle deck of a first ship and comprising at least one fluid conveying pipe (118) having a valve coupler (112) at the first end of each pipe, which is intended to be connected to a complementary valve of a fluid conveying pipe of a support structure installed on a second ship; a fixed structure (120) to be fixed on the deck and forming an ascending ramp (122); a movable structure (140) movably mounted on the ramp (122) of the fixed structure and to which is linked each fluid conveying pipe (118) for moving the valve coupler (112) of each pipe from a retracted position to an extended position, in which the complementary valve can be connected to the valve coupler, and means (150) for moving the movable structure (140) from the retracted position to the extended position.

Abstract: A mechanically energized annular packoff seal cartridge for metal-to-metal sealing with substantially concentrically arranged tubular members, such as the tubular wellhead housing and well casing of an oil and gas well. A tubular pressure responsive energizing mandrel having downwardly converging frusto-conical seal actuating surfaces is of a dimension for entry into the annulus between the wellhead seal bore and the rough outer surface of the well casing. Elastomer seals are carried by the energizing mandrel and establish sealing of the energizing mandrel with the wellhead housing and well casing A pair of soft metal seal rings are carried by the seal cartridge and are forced radially into metal-to-metal sealing with the wellhead housing and the rough outer surface of the well casing respectively by the double tapered seal actuating surfaces responsive to pressure induced downward force on the energizing mandrel.
