Optimarin ensures your compliance with all international regulations on Ballast Water Treatment. We design, deliver, install and service one of the industry’s most reliable, simple and effective systems. We focus exclusively on Ballast Water Treatment and we put our customers’ needs before all else. We believe in keeping a close and personal communication to be able to respond to our customers’ needs quickly and efficiently.
We operate in accordance with ISO 9001:2015 & 14001:2015 and our vision is to have the most environmentally friendly ballast water purification system in the world.


Optimarin AS was founded in 1994 in Stavanger, Norway and we were one of the first companies in the world to develop a system for environmentally friendly purification of ballast water.
We chose to pursue a solution that does not use any chemicals and leaves no residual products that are harmful to the ocean or the environment. In 2000, we were honoured by installing the world’s first ballast water treatment system on board the cruise ship Regal Princess.
After several years of testing, developing and patenting new technology, we finally obtained type approval for the Optimarin Ballast System in 2009, in accordance with Guideline 8 and the ‘International Convention for the Control and Management of Ships’ Ballast Water and Sediments, 2004’. The Optimarin Ballast System (OBS) uses approved technology that significantly exceeds the stringent requirements set out in the IMO Convention. In 2016, Optimarin was the first company to receive approval by the US Coast Guard under their significantly more stringent requirements.


At our main office in Sandnes, Norway, we have a fully operational Optimarin Ballast System test facility which may be used for training of customer’s technical personnel, or for internal R&D purposes.
Our Logistics department has established a main warehouse facility strategically placed in Europe, in Luxembourg – with excellent connections to airports, shipping ports and land-based transportation of our products on their way to our customers all over the world.
