    摘要: A motion restrictor device and system for an offshore loading arrangement is described, wherein the motion restrictor device comprises a first portion, at least two second portions protruding from opposite sides of the first portion, and a restrictive surface on the outside of the first portion, wherein the at least two second portions each comprise a protrusion at least partly extending form restriction areas between each respective two second portion and at least parts of the restrictive surface, adapted to restrict horizontal movement of a bridle.

    摘要: The system (10) for the transfer of fluid comprises a tubular fluid transfer line (2) comprising at one of its ends a coupling system (32) adapted to be connected to a target duct (33) for the transfer of fluid, and electrical actuators (11-13) for controlling the movement of the transfer line in space, each via an actuating shaft, characterized in that each of the actuators for controlling the movement of the transfer line comprises an electric motor with an output shaft, a speed reducer, the actuating shaft being rotationally driven by the motor output shaft by means of the speed reducer, which is reversible, so as to enable the actuating shaft to turn when an actuating torque is directly applied to it, and braking means for locking the actuator in position when movement control is in course and that actuator is not activated for that control.

    摘要: 1. A marine loading arm which includes at least one fluid transfer line having a fixed line end fixed to a base and a moveable line end provided with a coupling adapted for connection to a target duct. The coupling has at least three degrees of freedom relative to the base and the marine loading arm further includes a control device for controlling the movement and positioning of the coupling. The control device has at least three actuators, each of which controls movement of the coupling in a corresponding degree of freedom and each of which comprises an electric motor which is provided at an articulation of the loading arm providing one of the degrees of freedom. The control device further includes a first global positioning system device positioned on or adjacent the coupling for providing information on the absolute positioning of the coupling in space.
