A joint venture between Norwegian oilfield services firm Aker Solutions and Malaysia’s PTAS has agreed to provide offshore maintenance and modification (M&M) services to Brunei Shell Petroleum (BSP).

Under the five-year agreement, joint venture PTAS Aker Solutions will maintain and upgrade more than 200 offshore assets to maintain production levels.

PTAS Aker Solutions will ensure continuous service delivery to BSP. It will manage work from its premises in Kuala Belait, Brunei.

Aker Solutions has accounted the NOK4bn (approximately $380m) contract for the first quarter of this year.

In January, Aker Solutions announced the contract. It said it was part of a joint venture given a letter of award to provide offshore M&M services to an undisclosed client.

CEO Luis Araujo said: “We are pleased to continue our work for Brunei Shell Petroleum and look forward to help extend the lifetime of the offshore installations in the South China Sea.”

According to Aker Solutions, since the time it secured the Offshore Reliability Maintenance and Construction contract from BSP in 2012, the company has continuously improved the service delivery.

Last week, the company signed a master supply agreement with Chevron to provide umbilicals for oil and gas fields in the US Gulf of Mexico.
