The invention relates to an emergency disconnection system, especially for a fluid loading arm, comprising two valves which are joined together by means of a collar with a controlled opening, an actuator (400) comprising a single rod (401), and monoaxial kinematics such that a displacement of the rod (401) over a first part of the course thereof closes the two valves, and the displacement of the rod over the remainder of the course thereof opens the collar. Said system is characterised in that the actuator comprises means for ensuring the displacement of the rod (401) over said two parts of the course, said means being independently controlled on each of the parts and acting coaxially or essentially coaxially.

The invention relates to a coupler (10) adapted to be coupled to a complementary means (13) for the transfer of a fluid from the coupler (10) to the complementary means (13) and comprising a body (45) provided for the passage of the fluid and sealing means (42, 43) adapted to ensure fluid-tightness of the connection of the coupler (10) to the complementary means (13), means (40) for protecting the sealing means (42, 43), movable between a first position before connection, in which the said protecting means (40) project beyond the sealing means (42, 43) in the direction of connection, and a second position after connection, in which the said protecting means (40) are no longer projecting relative to the sealing means (42, 43), and damping means (44) which permanently urge the protecting means (40) towards their first position.
摘要:
A marine loading arm comprising at least one fluid transfer line having a line end fixed to a base (21) and a moveable line end provided with a coupling (26) adapted for connection to a target duct (35), the coupling having at least three degrees of freedom (A, B, C) relative to the base and at least one member of the group coupling / target duct or a member immediately neighboring one at least of the members of the group coupling / target duct comprising at least one means (33, 34) for providing information on positioning of the coupling; and a control device (1) for the movement and positioning of the coupling (26), comprising at least three actuators (27, 28, 29) each for controlling the movement of the system in a degree of freedom, wherein each actuators consists of an electric motor and is provided at an articulation of the loading arm providing one of the degrees of freedom, the control device furthermore comprising calculating means (41) adapted to: calculate the relative positioning of the coupling directly relative to the target duct according to the information provided by the positioning information means of the coupling, calculate control instructions to give to each of the electric motors such that their combined movements result in a movement of the coupling aimed at bringing the coupling closer to the target duct, apply said control instructions to bring the coupling closer to the target duct, reiterate the three preceding steps until the coupling is presented in front of the target duct in a position for connection.
摘要:
Assembly for loading and unloading products, comprising a balanced loading and unloading arm installed at a first location and having a compass-style duct system mounted by one of its ends on a base and provided at the other of its ends with a connection system suitable for connecting the compass-style duct system to a coupling means installed at the second location, this assembly comprising, in addition, a cable joined on the one hand to means integral with the base and suitable for subjecting this cable to a constant tension and suitable for being joined, on the other hand, to the second location, the assembly also comprising guiding means capable of co-operating with the cable so as to guide the connection system along a trajectory materialized by the said cable until the connection system is brought into a position of connection to the coupling means.
