Ballast water compliance

The shipyard has produced a large number of tugs of this type, based on a very successful design from Robert Allan Ltd. Over the years the original design has been refined in the light of experience gained locally and through other operators also using vessels built by Irving. In this instance the tugs are required to meet the requirements of Lloyds Register Ice Class 1A FS for operation in Scandinavian waters.PureBallst, Alfa Laval’s chemical free system for ballast water treatment, has received full Ballast Water Type Approval from DNV on behalf of Norwegian authorities. The certification confirms that PureBallast complies in full with pending ballast water treatment legislation from the IMO. Installed on board more than 25 vessels since its launch in 2006, PureBallast is the only solution without chemical treatment processes to be certified IMO compliant.
