Offshore mooring for ships, especially fuel tankers, comprises fixed structure with coupling arm connected to it by ball joint

摘要

An offshore mooring, comprising fixed structure (2) built on the sea bed (3) and a coupling (8) for connecting a vessel (1) to the structure together with a system for loading/discharging a cargo of hydrocarbons, has the coupling made in the form of an arm connected to the fixed structure by a self-lubricating ball joint (12). The arm comprises two lengthwise members forming the equal sides of an isosceles triangle, with the ball joint located at the apex, and their two free ends connected to the ship's prow (7) by articulated joints with their axes parallel to the ship's pitch axis.
