The Norwegian ballast water treatment manufacturer MMC Green Technology has lately won several contracts for its compact MMC BWMS. According[ds_preview] to a statement, this summer passed 100 systems installed onboard various types of ships worldwide. One of the latest retrofit projects was delivered as a full package, so-called »turnkey solution« from MMC Green Technology. As there was no need for docking, the job was done while the ship anchored at quayside. The ship will soon be trading in US waters. Currently, MMC is running tests for US Coast Guard and revised IMO G8 type approval and aims to achieve these within the next year. The MMC BWMS are available in the range 50 m³/h to 1.400 m³/h and are working chemical free based on particle filtration and UV-sterilisation.
