BP Trinidad & Tobago (BPTT) awarded McDermott International a contract award (from $250 million to $500 million) for the engineering, procurement, and construction (EPC) of the Cassia Compression Platform, located 35 miles southeast off the coast of Trinidad.
McDermott will provide EPC, hookup, and commissioning of the 8,928-ton Cassia C topsides, a 3,747-ton jacket, and a 793-ton bridge to link Cassia C with the existing Cassia B platform that currently sits in 223 ft of water.
The scope also includes brownfield modifications at Cassia B. The compression platform will be fabricated and constructed at McDermott's fabrication facility in Altamira, Mexico—where another recently delivered project for BPTT, Angelin, was fabricated. Trinidad Offshore Fabrication Company, a fabricator in Trinidad, will fabricate the jacket and the bridge landing frame.
This EPC contract follows the completion of a detailed engineering and long-lead procurement services contract McDermott completed for Cassia C earlier this year, as well as the completion of the EPC, construction, installation,and commissioning (EPCIC) contract of the Angelin project for BPTT.
Cassia C is BPTT's 16th offshore facility and the third Cassia platform, handling gas coming from its operations in the prolific Columbus basin. Cassia C will receive 1.2 Bscf/D of hydrocarbon gas through new piping from Cassia B across the bridge.
The gas will be compressed in three gas-turbine-driven compressors and returned to Cassia B for export. Liquids from Cassia C and Cassia B will be combined and boosted for export. First gas from the facility is expected in 3Q 2021.
