Alfa Laval has reported two major frame agreements covering the delivery of more than 50 PureBallast systems on tankers and bulk carriers over a three-year period.

Japanese ballast water management system manufacturer Miura Co has completed an environmental test that it says represents a landmark on its way to US Coast Guard (USCG) type approval.

Intercargo has proposed extended ballast water exchange be used for bulk carriers fitted with gravity discharged topside tanks, to retain vessel efficiency and avoid substantial modification.
