VIEC

Lifecycle power solutions provider Wärtsilä will deliver its Vessel Internal Electrostatic Coalescer (VIEC) systems for three North Sea oilfields, as part of contracts signed with Norway-based Aker Midsund.

The systems, which are claimed to improve the speed and efficiency of the separation process of oil and water onboard, are scheduled for delivery between April and August.

Wärtsilä will deliver VIEC to be used at North Sea’s Gina Krog, Mariner and Ivar Aasen oil fields.

For all three offshore projects, Aker Midsund is the separation package supplier towards the EPC contract holders.

In each project, Wärtsilä will supply a complete VIEC system with all required elements, all vessel internal cabling and tubing, penetrators and stainless steel frames and supports, including power distribution.

The systems will also enable the improvement of the quality of oil and water.

Wärtsilä Gas Solutions director Tore Lunde said: "Wärtsilä continues to actively develop new and innovative products to make oil and water separation more efficient, cost-effective and environmentally safe.

"The Wärtsilä VIEC technology offers a wide range of benefits, particularly in the lowering of both capital and operating expenditures."

"The systems will also enable the improvement of the quality of oil and water."

According to Wärtsilä, its VIEC system breaks the emulsion without excessive use of chemicals or heat, resulting in the increase of production, lowering of costs and promotion of environmental sustainability.

Electrostatic coalescer technology had been unavailable for use in inlet separators, prior to the development of the VIEC.

Said to be suitable for both offshore and onshore installations, the VIEC improves both oil and produced water quality.

It solves the problems often associated with emulsion and capacity limits in separators, and forces small water droplets to merge and form larger, faster sedimenting drops to improve the speed and efficiency of the separation process.
