FPSO awarded first-ever emissions abatement notation

Abate(F) covers emissions abatement from the flare tower, which has a low-pressure and high-pressure, closed system designed to recover any leaks, while operations will not include routine flaring, just during any over pressure and emergency.

Abate(Pr) covers process system vents and fugitive emissions abatement. FPSO Bacalhau will have a closed loop designed to recover waste gases and will recycle them back into the main processing unit. Modec will also minimises the number of flanges and ensure hydrocarbon service valves are in accordance with ISO 15848-2 to reduce fugitive emissions.

“Receiving the DNV Abate notation is an affirmation of our commitment towards the development of a sustainable future,” said Modec Singapore vice president and chief operating officer Eric Powell.

“We play our part in climate change mitigation by minimising greenhouse gases and other emissions across our business operations and supply chain, and by developing clean energy solutions to achieve global goals.”  

Abate(P+) involves enhanced emissions abatement from the power systems, which combines gas turbine generators and steam turbine generators in a cycle to generate around 100 MW of power to supply onboard systems and 45 MW of heat duty in total.

Modec will improve thermal energy efficiency by around 20% to reduce fuel consumption and emissions.

Abate(S) is for emissions abatement form the storage tanks, achieved by using conditional low-pressure fuel gas as the primary means of cargo tank blanketing.

This is paired with vapour recovery units, with redundancy, to recover gas evolved during tank loading to prevent venting to the atmosphere, while Modec would maintain inert gas generation with a back-up means.

Riviera’s Offshore Support Journal Conference, Asia, the premier annual event for the offshore energy and offshore vessels sector in the region, returns to Singapore on 17-18 September 2024. Use this link for more information and to register. Early bird rates are available until 2 August 2024.

Riviera’s Maritime Decarbonisation, Europe: Conference, Awards & Exhibition 2024, will return to Amsterdam, the Netherlands, 24-25 September 2024 to address critical environmental issues head-on. Focused on the industry’s energy transition, the conference offers a comprehensive forum for stakeholders across the maritime sector to explore solutions and strategies for achieving low-carbon shipping and zero-emissions shipping.
