BP Trinidad & Tobago (BPTT) confirmed the safe delivery of first gas from its Cassia C development.

Cassia C is BPTT's first offshore compression platform and its largest offshore facility, according to the company.

The platform enables BPTT to access and produce low-pressure gas resources from the Greater Cassia Area. It is the company's 16th offshore facility and is connected to the existing Cassia hub located about 35 miles off Trinidad's southeast coast.

“First gas from Cassia C is an important milestone for BP in Trinidad and Tobago," said BPTT President David Campbell. "This first offshore compression facility will allow us to unlock new resources and bring much-needed gas to market. I am immensely proud of the teams which have been working hard to bring this facility online.”

According to BP, Cassia C is expected to produce, at peak, about 200 to 300 MMcf/D, with production to go toward meeting BPTT’s gas-supply commitments and will be important to sustaining the country's LNG and petrochemical industries.

“I am proud of our achievement to deliver this project while keeping our people safe throughout a global pandemic," said Ewan Drummond, BP senior vice president, projects, production, and operations. "Cassia C is a great example of bp's resilient hydrocarbons strategy in action—providing the energy the world needs now and helping us invest in the energy transition. I would like to thank our team for their commitment in the safe execution of this project."

In January 2019 McDermott was awarded the contract for the engineering, procurement, and construction (EPC) of the topsides, jacket, and bridge linking the Cassia C platform to the Cassia B platform sitting in 223 ft of water.

The Cassia C platform’s jacket—its legs and supporting frame—was built at the TOFCO fabrication yard in La Brea, Trinidad. Heerema Marine Contractors' semisubmersible crane vessel, the Sleipnir, installed the jacket in 2020.

Its 7,800-metric-ton topside structure was built in the McDermott fabrication yard, Altamira, Mexico. It was installed in 2021 by Heerema's Thialf crane vessel.

BPTT operates in approximately 680,000 acres off Trinidad’s east coast. In addition to the 16 offshore platforms, the company also has two onshore processing facilities.
