Kurita Water Industries Ltd. (Head Office: Nakano-ku, Tokyo; President: Michiya Kadota; hereinafter "Kurita") is pleased to announce that the KURITA BWMS -- a system that treats ballast water, or water taken into the ship to ensure its trim, stability and structural integrity -- has been awarded the type approval from the Ministry of Land, Infrastructure, Transport and Tourism in accordance with the requirement of the specifications contained in the Guidelines contained in IMO resolution MEPC.174(58). In response, Kurita will begin marketing the KURITA BWMS.

KURITA BWMS was awarded the Final Approval in accordance with the "Procedure for approval of ballast water management systems that make use of active substances (G9)" stipulated by the International Maritime Organization (IMO). The type approval has just been awarded because it was confirmed that the system conforms to the ballast water discharge standards and that Kurita has an appropriate quality control system as a manufacturer of ballast water treatment systems, in accordance with the "Guidelines for approval of ballast water management systems (G8)."

The International Convention for the Control and Management of Ships' Ballast Water and Sediments will enter into force in September 2017. In response to this, Kurita will promote proposal activities aiming to receive more orders for KURITA BWMS.

[Features of KURITA BWMS]

This water treatment system uses only water treatment chemicals to eliminate aquatic organisms (in the ballasting process) and neutralize the ballast water (in the de-ballasting process). It comes in a simple configuration with no filter and consists of chemical storage tanks, equipment for feeding chemicals, and controlling equipment. It therefore permits a flexible layout and does not need large-scale reconstruction work. The system's notable advantage is that it can be retrofitted to a ship in service more quickly. It can also be retrofitted during a regular inspection of the ship.
