BP Trinidad & Tobago LLC (BPTT) has let a contract to McDermott International Inc. for the engineering, procurement, construction, installation, and commissioning (EPCIC) of Angelin natural gas field 25 miles offshore eastern Trinidad and Tobago.
The EPCIC contract follows the successful completion of a multiphase engineering contract, including pre-front end engineering design (FEED), FEED, and pre-execution engineering contracts previously awarded to McDermott for Angelin’s initial design and execution planning. McDermott’s team in Houston led the engineering and execution planning efforts with support and work share from the company’s engineering center in Chennai, India.
Building off its pre-FEED and FEED work, McDermott will design, procure, fabricate, transport, install, and commission a six-slot wellhead platform and 26-in. subsea pipeline using its project management and engineering team in Houston. The 900-tonne, four-legged main pile jacket and 1,200-tonne, four-deck topside for Angelin will be constructed at the Altamira, Mexico, fabrication facility. The platform and pipeline are scheduled to be installed by McDermott’s DLV 2000.
The Angelin project is a dry gas development in the northern Columbus basin in 213 ft of water. The gas will be exported to the Beachfield-Atlantic LNG facility and the liquids to the Galeota terminal via a 13-mile, 26-in. export pipeline.
While the design throughput will be 600 MMscfd of gas, its actual production should be about 360 MMscfd, BPTT said.
The gas will be exported through the pipeline to the Serrette facility and on to the nearby Cassia platform for processing.
Cost of the Angelin project, including the drilling of the wells and construction of the facilities, is expected to reach $1 billion.
BPTT is expected to build two more platforms over the next 6 years to support its production from its Savannah and Macadamia discoveries.
Angelin is slated to start gas production in 2019.
