128/17/Gen.Inf. USCG issues further BWMS Type Approval certificates

On December 23rd, the US Coast Guard Marine Safety Center issued the second U.S. Coast Guard Ballast Water Management System Type Approval Certificate to Swedish manufacturer Alfa Laval Tumba AB, and third Certificate to Norwegian manufacturer OceanSaver AS after a detailed review of each manufacturers type approval application determined the system met the requirements of 46 CFR 162.060.

The Alfa Laval PureBallast 3 system incorporates four ultraviolet reactor sizes: 170, 300, 600, 1000. The reactors can be arranged either individually or in parallel to achieve treatment capacities ranging from 85m3/h to 3000m3/h.
This initial approval only covers those systems which use the tested UV reactor sizes of 300 and 1000. Future approval of the 170 and 600 reactors is dependent on Coast Guard approval of the UV reactor scaling studies, which are currently under review by the Marine Safety Center.
The OceanSaver BWTS MKII incorporates an electro-chlorination, or electrodialysis, process to achieve treatment capacities ranging from 200m3/h to 7200m3/h.
A copy of the type approval certificates may be obtained by contacting the respective manufacturer.
