Providing CALM buoy services for Chevron Nigeria

In early 2013, Fendercare Nigeria was awarded the contract to inspect, refurbish and commission the Escravos Gas To Liquids (EGTL) CALM buoy and PLEM.

The EGTL CALM Buoy and PLEM were originally built for Chevron in 2006. The Buoy and PLEM had been stored on a quayside since 2007 with little to no preservation work carried out.

Part of Fendercare Nigeria’s workscope was to inspect all the existing systems which included the coating system, hydraulic and electrical system, surge relief system, water tight integrity, main roller bearing, lifting points and lifting equipment plus all ancillary equipment. A full project execution plan detailed the work to be carried out and the equipment to be replaced in the event of failure.

The Buoys commissioning was executed under the supervision of ABS who was the Classification Society and Chevron Nigeria Limited.
