Arctic Foxtail: Oil Cleanup Tech

A new oil spill response device designed to be capable of cleaning up spills in arctic conditions has been launched in an effort to bolster Norway’s spill preparedness.

Once on scene, the unit was to be connected to a vessel’s ballast water manifold to take on ballast water and treat it to the D2-standard as prescribed by the IMO’s Ballast Water

Management Convention.

InvaSave is the world’s only land-based ballast water man- agement system that is IMO- certi? ed to carry out such a job in a single treatment step, without any holding times or use of chemicals. (Photos: H. Henriksen) 56 Maritime Reporter & Engineering News • JANUARY 2019
