State-owned Abu Dhabi Marine Operating Company (Adma-Opco) is to invite contractors to bid by the end of December for a deal to manage the overhaul of its offshore production facilities.

Details of the scheme have only just come to light, but contractors tell MEED the offshore division of Abu Dhabi National Oil Company asked international engineering firms to express interest in the project management consultancy contract in September.

The five-year deal is valued at $50-60m. It covers preliminary front-end engineering and design (Feed) and full Feed studies, contractor selection and project management of five engineering, procurement and construction contracts to upgrade the offshore infrastructure. The five projects include an upgrade of all Adma-Opco’s existing process facilities, modifications to its gas flares, instal-lation of crude oil loading pumps, supply and installation of oil storage tanks, and a capacity increase at the company’s coil tubing units.

“Although it does not seem like a huge deal in monetary terms, it will mean a lot of work in an exciting area of development,” says the business development executive at one firm planning to bid for the contract.

Companies in line to bid include the US’ Fluor Corporation, the US/Canadian Veco, the UK’s Mott MacDonald, the Netherlands’ Tebodin, the UK’s Amec and Australia’s Worley Parsons.
