Ballast Water Treatment

The Coldharbour Marine approach to ballast water treatment is unique.

The Coldharbour system is not an in-line system and does not treat the ballast water at uptake. Therefore there are no filters and concerns over flow rates, pressure drops and power consumption are irrelevant. Ballasting and de-ballasting continues as normal.

Having studied the IMO and applicable National regulations in depth, and having spoken to a number of ship owners and ship operators globally, our conclusion is that no “one BWT technology” is suitable for all types of vessels and all usage profiles.

With this in mind, Coldharbour has developed it’s unique "in-tank, in-voyage" inert gas based ballast water treatment technology. Specifically designed and optimised for large tankers, LNG/LPG carriers and Bulkers.
