The US Coast Guard Marine Safety Center has issued its fourth Ballast Water Management System Type Approval Certificate to Sunrui Marine Environment Engineering Co., Ltd. after a detailed review of the type approval application determined the system met the requirements of 46 CFR 162.060. The Sunrui BalClor system incorporates a three step process consisting of filtering and electrolysis during uptake and neutralization at discharge. This approval covers fourteen models with maximum treatment rated capacities between 170m3/h and 8500m3/h.
Just this past week four more States became Party to the IMO’s Ballast Water Management Convention, designed to counter the threat to marine ecosystems by potentially invasive species transported in ships' ballast water. The Bahamas deposited its instrument of accession on Thursday (8 June), following accession by Singapore (8 June), ratification by Australia (7 June) and accession by United Arab Emirates (6 June). Saudi Arabia became a Party in April. This brings the number of States party to the BWM Convention to 59, representing 65.18 % of the world's merchant fleet tonnage. The Convention enters into force on 8 September 2017 and will require ships to manage their ballast water, which can contain thousands of aquatic or marine microbes, plants and organisms, which are then carried across the globe.
