Wärts i lä OWS Solution that meets the needs

OWS solutions can be divided on basis performance characteristics, i.e. high

performance and or low performance. Wärtsilä OWS are categorized as high

performance equipment.High performance equipment gives the benefit of high

availability and performance over the products entire lifecycle guaranteeing low

operating costs and high a safety standard.

Slop water treatment for Offshore

The Wärtsilä slop water treatment system is designed to treat drill slop water and make it dischargeable to the sea without further treatment. The unit will significantly reduce drill slop sent onshore for treatment, depending on the rig, by as much as 80-90 %.
