Alfa Laval has completed all the land-based tests required for US Coast Guard (USCG) type-approval on the 3.1 version of its PureBallast ballast water management system (BWMS) and expects to submit a USCG type-approval application “in the coming weeks,” the company said in a statement today. It has already passed its shipboard tests.
Its tests used the USCG-approved CMFDA/FDA (staining) method and were carried out by Denmark’s DHI laboratory. They used the same hardware, power consumption and flow as the IMO-approved version of the system and were completed in Q2 of this year, the company said. It is now compiling its type-approval application around those tests’ results.
“PureBallast has achieved high-performance results without any change to its components or system design,” said general manager of Alfa Laval’s PureBallast business centre Anders Lindmark. “The tests show that PureBallast provides reliable biological disinfection at full flow, whether by IMO or US Coast Guard standards,” he added.
