Alfa Laval says it won an order to retrofit up to 53 vessels with its ballast water treatment gear.
The Swedish manufacturer, one of only four to win the US Coast Guard's type approval for ships voyaging in US waters, said it signed frame agreements with two different shipowners for the supply of Alfa Laval PureBallast systems.
The systems will be delivered during a three-year period and retrofitted on tankers and bulk carriers.
