ACE (Arup Concept Elevator) platforms, Offshore, Philippines Sea

An award-winning, self-installing and re-locatable offshore platform.

The platforms combine the advantages of traditional fixed platforms with the versatility offered by a mobile unit.

ACE platforms are cost-effective solutions in their own right. But they are particularly economical where reuse allows several reserves to be exploited, in areas of high decommissioning costs, or where access to specialist installation vessels is limited and costly. ACE platforms can be fabricated at local yards without extensive equipment or specialist expertise. When complete they need only tugs and strand jacks for installation and relocation.

Platform topsides are easy to expand or modify as field requirements change but when platforms are no longer needed, they can simply be towed to the quayside for relocation or decommissioning. This is much easier and more cost-effective than decommissioning a platform in-situ.

Proven track record

The first ACE platform, the Hang Tuah , was installed in West Natuna Sea in 2001. Shipped from South Korea, before being released and towed a short distance to site, the platform deck was raised to its final in-service elevation within 48 hours of arrival.

Since then, there have been three more individually tailored ACE platforms – including the Maari Wellhead Platform in the Taranaki Basin off New Zealand. Capable of producing 35,000 barrels of crude oil per day, Maari is one of the highest vertical jacked structures in the world.

Our fourth platform will be installed for Shell in the West Philippine Sea during 2015. The Malampaya Depletion Compression Platform (DCP) will extend the life of the Philippines’ only indigenous natural gas source.
