Maersk Supply Service has won a contract to replace the mooring installation of a floating production storage and offloading (FPSO) unit in the Gulf of Guinea.

The company will provide the full scope of work from project management to execution for an unnamed "American oil major", a release said Thursday.

Work will commence immediately and is scheduled to be completed by the end of this year, Maersk Supply said.

New direction

The contract win comes less than a month after parent group AP Moller-Maersk officially aborted its plans to sell its offshore support vessel division.

Instead, the group said Maersk Supply would aim to diversify into new markets — a strategy that appears to be bearing fruit with this new deal.

“With this major contract, we add both a new customer and a new country to our track record of providing integrated solutions," Steen S Karstensen, Maersk Supply chief executive, said of the Gulf of Guinea deal.

"While we have supported this customer with marine services in the past, we are pleased that they recognise our expanded capabilities and have shown their trust in MSS to deliver on this complex scope of work."

Scope of work

Maersk Supply said it will look after engineering, procurement, transportation of mooring equipment, safety management and offshore execution at the installation.

Four of MSS's large anchor handling vessels will be employed under the contract and the company will also provide remotely operated vehicle (ROV) and survey services.

InterMoor will support the project in the engineering, design and offshore execution of the mooring system operations.

The project will be led from the company's office in Aberdeen with support from an project team in Houston.

Neither contract value, client nor the specific FPSO unit were disclosed.

AIS data shows six different FPSOs operated by American oil majors in the Gulf of Guinea.

Four FPSOs owned by ExxonMobil and another owned by Chevron are moored in Nigerian waters. Hess has another stationed in offshore Equatorial Guinea.
