Marine Terminals - CALM Buoys

Terrunganu #2 CALM - West Malaysia

SOFEC designed, constructed and installed a replacement CALM system to accommodate 35,000 to 85,000 dwt tankers in 20m water depth. The system is linked via four 18-in. pipelines to a refinery located two miles away. In 1982, SOFEC designed, constructed, and installed a multi product import/ export CALM system for Petronas. SOFEC removed the existing system and installed a replacement CALM plus 55m of chain per leg. This system uses a relatively small main bearing and three heavy outboard turntable rollers running on a replaceable crane rail track.

The CALM buoy itself features six self-aligning chain stoppers, vertical pull hawse pipes, six watertight compartments, and closed centerwell. The buoy deck is equipped with a quick disconnect manifold for manual operation of the hydraulic system for control of underwater PLEM ball valves.

The Terengganu CALM is a low maintenance design with fully sealed rotating components that require minimal lubrication and can be replaced without removing the turntable. All components are designed to allow full field servicing.
