MOTION DECOUPLING MECHANISM FOR FLUID SWIVEL STACK

摘要

A mechanism for decoupling over a selected angle the rotational motion between a marine vessel moored to a single point mooring system such as a single anchor leg mooring (SALM) and the fluid swivel stack of the single point mooring system. In a preferred embodiment, a mooring swivel having a coupling means is positioned on the SALM at the base of the fluid swivel stack. Two spaced-apart stops are attached to the fluid swivel on either side of the coupling means. As a further embodiment, shock absorbers may be positioned on each stop between the coupling means and each stop.
