Device for providing information on positioning of a moveable coupling of a marine fluid loading system

摘要

A device (1) for providing information on positioning of at least one moveable coupling (26) of a marine loading system (2), the system 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, the coupling or a member immediately neighboring the coupling having at least one means for providing information on the positioning of the coupling (33) either adapted to cooperate directly with a means (34) for providing information on positioning of the base disposed on the base or on a member immediately neighboring the base to provide, on the basis of the information on positioning of the base, information on relative positioning of the coupling directly relative to the base, or adapted to provide information on absolute positioning of the coupling (26) in space, and, the base having a fixed position in space, the device has a calculating means making it possible to calculate on the basis of the information on absolute positioning of the coupling and data on positioning of the base fixed in space, information on relative positioning of the coupling directly relative to the base.

1. A device for providing information on the positioning of at least one moveable coupling which is located on a movable end of a fluid transfer line of a marine loading system and is adapted for connection to a target duct, the other end of the fluid transfer line being fixed to a base, the device comprising:
at least one means positioned on or adjacent the coupling for providing information on the positioning of the coupling; means for calculating in real time the position of the coupling relative to the base from information on the positioning of the base and information provided by the coupling positioning information means; wherein the calculating means is configured to compare in real time the calculated position of the coupling relative to the base to data defining at least one authorized positioning zone for the coupling; and an optical device which is positioned on or adjacent one of the base and the coupling and is adapted to emit a luminous beam towards the other of the base and the coupling, detect the reflected beam from the base or the coupling, measure the travel time of the beam and deduce therefrom a first distance between the coupling and the base; wherein the calculating means is adapted to calculate a second distance between the coupling and the base from the position of the coupling relative to the base, compare the first distance to the second distance, and cause a perceptible alarm signal to be emitted when the second distance varies from the first distance by a predetermined amount.
