Bardex Corp. has delivered a linear chain jack mooring system for a floating production facility designed for 1,300 m (4,625 ft) of water and installed offshore East Malaysia.
The mooring system consists of 10 linear chain jack assemblies and 10 deck-mounted turndown sheave assemblies. The chain jacks will service the specified 0.4-in. (124 mm) Grade 4 chain size, and are designed with a maximum rated haul-in/pay-out capacity of 1,200 kips, mechanical hold capacity of 1,550 kips, and a chain stopper capacity of 3,230 kips.
A self-contained, air-cooled hydraulic power unit assembly, with two independent 250 hp motor/pumps, provides a haul-in/payout speed of 0.55 m (1.8 ft) per minute for each group of jacks, or 0.9 m (3 ft) per minute for a single jack operation. Supported by the system’s programmable logic controller, four pedestal mounted control consoles include all instrumentation and control actuators for operation of clusters of two or three linear chain jacks.
