Aker Solutions introduces new low-cost platform for marginal fields

FORNEBU, Norway -- Aker Solutions has introduced a new lighter weight semisubmersible platform that will help producers unlock more marginal oil and gas fields in harsh environments across the globe. The platform delivery time has also been reduced.

The new Lean Semi will help bring on stream fields holding as much as 300 MMboe at water depths of 100 m to 400 m. The topside weighs about 6,000 metric tons, which is 30% lighter than similar solutions.

“We envisage these platforms will be ideal in developing marginal resources that are located next to bigger fields with excess processing capacity,” said Valborg Lundegaard, head of Aker Solutions' engineering business. “The concept combines lean design philosophy with the highest levels of safety.”

The platform brings together elements from two proven designs for the North Sea and the Gulf of Mexico and is the result of a painstaking review of every single platform item to enable a 60,000 bpd production capacity at a lower investment cost. It has an unmanned hull combined with a single flat top deck to ensure structural integrity. The topside is also designed to use standardized equipment, meaning equipment skids and small modules can easily be placed directly on the deck.
