The approval is for the company’s EcoBallast BWMS which consists of filtration with UV treatment during uptake and discharge.
This is the 22nd certificate issued by the Coast Guard so far and the second one obtained by HHI. In October 2018, HHI received an approval for its HiBallast BWMS.
Worth noting is that China’s COSCO Shipbuilding Industry obtained its first BWMS type approval in September this year.
