Aker Solutions announced today a new type of lean semi-submersible platform that will help producers unlock more marginal oil and gas fields in harsh environments.

According to the Norwegian oil services company, the new model is lighter and faster and allows producers to maintain output levels at lower costs.

“We envisage these platforms will be ideal in developing marginal resources that are located next to bigger fields with excess processing capacity,” the head of Aker Solutions’ engineering business, Valborg Lundegaard, said.

“The concept combines lean design philosophy with the highest levels of safety,” he added.

The new platform concept is expected to help bring on stream fields holding 300 million barrels of oil equivalents (boe) at water depths of 100 to 400 metres (328 to 1,312 feet).

On top of that, the topside weighs approximately 6,000 tonnes, which is 30% lighter than similar solutions, and the platform delivery time has also been reduced.

Additionally, the topside has been designed to use standardised equipment, which means that equipment skids and small modules can easily be placed directly on the deck.

The new platform will bring together elements from two proven designs for the North Sea and the Gulf of Mexico, Aker explained.

It is the result of a review of every single platform item to enable a capacity of 60,000 barrels per day (bpd) with a lower investment cost, the company stated further.

As well as this, the platform has an unmanned hull, combined with a single flat top deck, with the purpose of ensuring its structural integrity.

Aker Solutions is known for designing some of the world’s most advanced semi-submersible drilling and production platforms, as well as floating production storage and offloading vessels (FPSO) and tension-leg platforms for use in deep (9,842 feet) or medium (984 feet) water depths.
