Malampaya CALM
Scope of Work
SOFEC designed, constructed, and installed a CALM Buoy system for the SHELL Malampaya Deep Water Gas to Power project.
The Malampaya CALM transfers condensate from the concrete gravity Production Platform to tankers through a 2.5km long 24-in pipeline. Located in 75m water depth, the CALM buoy is capable of
accommodating 40,000 – 110,000 dwt tankers.
