Sevan updates FPSO projects, conceptual studies

Offshore staff

ARENDAL, NorwaySevan Marine continues to provide engineering support for a study related to a potential FPSO-based development in the UK offshore sector.

It is also assisting construction of a floater at the COSCO shipyard in China for Dana Petroleum’s Western Isles project in the East Shetland basin.  

However, the company’s work on the Goliat field in the Norwegian Barents Sea, where one of its cylindrical FPSOs is in operation, is likely to finish in the coming months.

During 3Q, OMC commissioned the company to assess the Sevan Marine cylindrical hull design for application on the Wisting field development in the Barents Sea. In addition, the company completed a study for an oil major regarding use of the Sevan Marine design for a gas development.

Sevan continues to work on new applications for its cylindrical technology, including participating in the Clean Electricity Production from Offshore Natural Gas (CEPONG) study that is supported by the Scandinavian research institute SINTEF and other industrial partners.

This is evaluating use of a cylindrical hull as an offshore natural gas power plant with carbon-dioxide capture and reinjection.
Sevan Marine hopes to obtain approval to use its cylindrical hull design with steel catenary risers in the US Gulf of Mexico as a non-disconnectable FPSO with the ability to retain cargo during a hurricane.

This would be a first in the sector, and cheaper, Sevan claims, than the currently used disconnectable, turret-based solutions.
