Nippon Yuka Kogyo's SKY-System Earns MLIT Approval.

Tokyo, Oct 21, 2014 - (JCN) - Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) grants approval to SKY-System, developed by NYK Group's Nippon Yuka Kogyo Co. Ltd. with Katayama Chemical Industries Co. Ltd.

The SKY-System is a ballast-water management system. Ballast water is seawater that ships carry to maintain balance, it is normally taken on in ballast tanks in the ship's bottom at the unloading port, and then discharged at the loading port.

SKY-System disinfects marine organisms carried in ballast water so that local ecosystems are not affected by foreign organisms. This system makes use of Peraclean Ocean, a biodegradable biocide developed by Evonik Industries (Germany) and Katayama Chemical Industries for environmentally sound ballast-water treatment; it's a chemical treatment that sterilizes aquatic organisms and bacteria contained in ballast. This is the very first system to reliably sterilize organisms irrespective of the quality of the ballast water - e.g., seawater, brackish water, freshwater, ice-cold water - enabling the ship to take on and discharge ballast water in areas around the world.

The energy-efficient system is easy to maintain and can be installed on all types of vessels without dry-docking. Moreover, it is a simple, integrated unit that requires only a small space, so it is easy to install during operation without significant remodeling. In this sense, it is a breakthrough ballast-water management system that requires minimal off-hire (or none, in most cases) and minimizes installation cost.
