Under a new distribution agreement, TeamTec will provide worldwide sales and marketing of the Japanese Kurita BWMS, as well as handling project execution, delivery and lifecycle service.
The Kurita BWMS was developed by Kurita Water Industries of Japan, a company that supplies chemicals to produce industrially clean water for manufacturing processes.
The Kurita BWMS is said to be unique in that it does not use filters (see diagram), but only water treatment chemicals (sodium hypochlorite) to eliminate aquatic organisms in the ballasting process and neutralise the ballast water in the deballasting process.
The configuration is simple: no filter, chemical storage tanks, equipment for feeding chemicals and controlling equipment.
The system is IMO G8/G9 approved and currently is in the process of obtaining both revised G8 approval and USCG type-approval.
According to Kurita, the BWMS does not need large-scale reconstruction work. The system's notable advantage is that it can be retrofitted during a regular inspection of the ship.
TeamTec head of sales and projects Edvin Tunheim Tønnessen said “…from customers with older vessels we have seen an increasing demand for ballast water management systems that do not use filters and generally are easier to install. Kurita BWMS will enable us to offer a system with a very low system installation cost, as well as give us a good alternative for vessels with low ballast water flow rates.”
TeamTec is a subsidiary of the IMS Group of Norway, which in 2017 purchased the rights to Oceansaver BWMS after the original company went bankrupt.
The IMS Group continues to manufacture and support the Oceansaver BWMS, now sold under the name TeamTec Oceansaver BWTS.
