Abstract

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. The mechanism includes two spaced-apart stops attached to the fluid swivel stack and a coupler positioned between the stops and attached to a mooring swivel at the base of the fluid swivel stack. Shock absorbers may be positioned on each stop between the coupler and each stop.
