Barbers Point (Tesoro) CALM
Scope of Work
SOFEC will design, construct and installea CALM terminal for crude oil, bunker fuel, gasoil, kerosene and gasoline and fuel oil. This unique SOFEC CALM buoy is designed with a three-product swivel, which
incorporates a crude oil circuit, a white product circuit, and an export sales circuit.
This SPM is an import CALM Buoy serving the Tesoro Kapolei Refinery. The SPM is located 2.5km offshore from Barber’s Point. This SPM replaces an existing 8-point spread mooring system and was installed
into the existing anchor chain spread. The installation of the new unit into theold mooring pattern will be achieved by removing 2 of the existing 8 anchor legs, lengthening the remaining 6 legs and installing an auxiliary gravity anchored PLEM.
