DNV GL has awarded the Chinese scrubber manufacturer Shanghai Bluesoul Environmental Technology with an Approval in Principle (AiP) in recognition of the technical feasibility of the BlueSulf scrubber system. The AiP is the first of its kind for a scrubber according to the new DNV GL rule set, and the first for a Chinese scrubber manufacturer. DNV GL will also provide advisory services to Bluesoul, including hardware-in-the-loop testing, simulations using the DNV GL COSMOSS tool and analyses using computational fluid dynamics (CFD). “We are very pleased to be the first Chinese supplier to receive this AiP and it demonstrates BlueSulf’s design in compliance with DNV GL class rules requirements, by using the sodium alkali method to clean exhaust gases.
