Response of Single Anchor Leg Mooring Under Earthquake

Abstract

The SALM (single anchor leg mooring) has been applied at many locations throughout the world, both for conventional oil import and export terminals and for deepwater production storage and loading facilities. The SALM has proved to be a safe, reliable, and efficient means of mooring and loading or unloading both large and small tankers. Experience and continucd research have lead to design improvements which are now being incorporated in new SALM. The SALM mooring buoy is anchored through a single pretensioned anchor leg to a gravity type mooring base at the seafloor. This paper describes model tests of the response of a SALM subjected to earthquake excitation.
