Shell has started oil production from the Gumusut-Kakap floating platform off the coast of Malaysia, the latest in a series of Shell deepwater projects, a company press release said.

The Gumusut-Kakap Field is located in waters up to 1,200 m (3,900 ft) deep. The platform is expected to reach an annual peak oil production of about 135 Mbbl/d once fully ramped up. With oil production now underway, work on the gas injection facilities is continuing with an expected startup during 2015.

Assembling the vast structure of the floating platform, the four decks of which total nearly 40,000 sq m (430,560 sq ft), involved the world’s heaviest onshore lift. The project uses Shell Smart Fields technology to carefully control production from the undersea wells to achieve greater efficiency. Oil is transported to the Sabah Oil and Gas Terminal onshore at Kimanis, Malaysia, via a 200-km (124-mile) pipeline.

The Gumust-Kakap project is a joint venture between Shell (33%, operator), ConocoPhillips Sabah (33%), Petronas Carigali (20%) and Murphy Sabah Oil (14%).
