USCG grants Chinese BWM system type approval

Jun 16 2017

China’s Sunrui Marine Environment Engineering has become the fourth ballast water management system (BWMS) manufacturer to receive US Coast Guard (USCG) type approval.

This certificate was issued after a detailed review of Sunrui BalClor BWMS type approval application to determine if it met the requirements of 46 CFR 162.060.

The BWMS incorporates a three step process consisting of filtering and electrolysis during uptake and neutralisation at discharge. This approval covers 14 models with maximum treatment rated capacities between 170 - 8,500 cu m per hour.

In early December last year, the USCG awarded the first type approval certificate to Norwegian ballast water treatment (BWT) specialist Optimarin for its Optimarin Ballast System (OBS).

Later the same month, Swedish Alfa Laval and Norway-based OceanSaver were granted BWMS type approval certificates.
