Aker unveils semisubmersible platform for marginal fields
Aker Solutions has introduced a lighter weight and faster to deliver semisubmersible platform that aims to help unlock more marginal oil and gas fields in harsh environments.
The new Lean Semi will help bring onstream fields holding as much as 300 MMboe at water depths of 100 m to 400 m (328 ft to 1,312 ft).
The topsides weighs about 6,000 metric tons, which the company claims, is 30% lighter than similar solutions. Platform delivery time has also been reduced.
Valborg Lundegaard, head of Aker Solutions’ engineering business, said: “We envisage these platforms will be ideal in developing marginal resources that are located next to bigger fields with excess processing capacity. The concept combines lean design philosophy with the highest levels of safety.”
The platform brings together elements from two proven designs for theNorth Sea and the Gulf of Mexico. It is the result, the company says, of a review of every single platform item to enable a 60,000 b/d production capacity at a lower investment cost.
The platform has an unmanned hull combined with a single flat top deck to ensure the structural integrity. The topsides is also designed to use standardized equipment, meaning equipment skids and small modules can easily be placed directly on the deck.
