Acteon unit installs retrofit CSP offshore Bahrain

MANAMA, July 25, 2018

Global engineering contractor 2H Offshore said it has completed the installation of a retrofit conductor supported platform (CSP) offshore Bahrain for oil giants Bahrain Petroleum Company (Bapco) and Schlumberger.

This enabled a successful appraisal well to be transitioned to production in 26-m water depth, offshore Bahrain, within six months of project award, said the statement from the company.

A unit of UK-based specialist subsea services company Acteon Group, 2H Offshore specialises in the design, structural analysis and integrity management of riser and conductor systems used in the drilling and production of offshore oil and gas reserves.

On behalf of Bapco and Schlumberger, 2H Offshore designed a tripod CSP with boat landing that can support three surface trees with a total work area of just 90 sq m, it stated.

According to 2H Offshore, the platform was a particular challenge as it was clamped retrospectively onto the drilled conductor under an already installed surface tree.

Additional conductors were driven to provide support for the CSP and enabling two potential future wells. The CSP consisted of a subsea template, a top platform, top brace structure, single deck and boat landing, it stated.

Hassan Saleh, the principal engineer at 2H Offshore, said: "Completing this project within the tight timeframe despite the challenge of retrofitting it under an installed tree, shows that with the right design and excellent network, a fast-track, light-weight, retrofit structure is an excellent choice for many shallow water fields."

The structure was installed entirely by Shelf Drilling’s Key Hawaii drilling rig, aided only by an observation ROV. In addition to the design and engineering, 2H Offshore managed fabrication and supervised offshore installation on-site in Bahrain.

2H subcontracted Arab Shipbuilding & Repair Yard (Asry), Bureau Veritas, as well as sister companies Claxton Engineering and Seatronics who all contributed to the successful completion of the project, said Saleh.

"Seamless collaboration with our clients, and the professionalism from Asry, the local fabrication yard, ensured this project ran efficiently, to specification and on schedule," he added.-TradeArabia News Service
