Commercial Application of First Japanese-made
Ballast Water Management System, JFE BallastAce
The First Retrofit of a BWMS among Japanese Carriers
|
 |
Nippon Yusen Kabushiki Kaisha (NYK; head office: Chiyoda-ku, Tokyo; president: Yasumi Kudo) has announced that it will install a ballast water management system*1 called JFE BallastAce*2, which was developed by the JFE Engineering Corp. (JFE Engineering; head office: Chiyoda-ku, Tokyo; president and CEO: Sumiyuki Kishimoto), on one of its pure car carriers, Emerald Leader. JFE BallastAce will be the first Japanese-made system to reach commercial application after receiving type approval from Japan痴 Ministry of Land, Infrastructure, Transport and Tourism. The system is to be installed on Emerald Leader at Universal Shipbuilding Corp.痴 Innoshima Shipyard while the vessel is undergoing dry-dock work in August 2010.
As part of NYK痴 commitment to protecting the global environment, the company began a study of installation of ballast water management systems (BWMSs) on its ships before the ballast water management convention*3 takes effect. A subsidiary of NYK, the Monohakobi Technology Institute (MTI), had also participated in joint testing of the JFE BallastAce system with JFE Engineering from the demonstration test stage. NYK selected the JFE BallastAce for implementation after its study concluded that the system offers total effectiveness, including reliability and future potential, on the vessel. This JFE system will be the first BWMS to be installed on an NYK fleet vessel.
The JFE BallastAce system provides a superior mix of three functions耀eawater filter elements, chemical agents*4, and Venturi tubes*5庸or treatment of aquatic organisms and bacteria contained in ballast water. The system realizes treatment reliability, ease of equipment layout, and excellent safety for the crew and environment at a low cost. JFE BallastAce is available in a complete product lineup, from small-scale units to a 3,500m3/h system that boasts the world痴 largest treatment capacity in a single unit, enabling installation on ships of any size.
Based on its experience with Emerald Leader, NYK plans to conduct a successive study of installation on other ships the company owns and manages, and will continue to contribute actively to protection of the environment. JFE Engineering will provide full, detailed technical service and after-service to clients in the shipping and shipbuilding industries, and expects to receive further orders for the new system.

| *1: Ballast water management system (BWMS) |
| |
Ballast water is seawater that ships carry to maintain balance. Ballast water is normally taken on in ballast tanks in the ship’s bottom at the unloading port, and then discharged at the loading port. The BWMS is a system that processes marine organisms carried by ballast water without destroying the ecosystem. Installation of BWMSs on all oceangoing ships will be required to satisfy the treatment standards provided in the ballast water management convention. When the convention takes effect, the ships that are subject to regulation will be expanded successively to include newly constructed ships and existing ships, in that order, by January 2017. |

| 2004 |
Start of development |
| 2008 |
Land-based tests |
| 2009 |
Onboard tests (jointly with MTI, a member of the NYK Group) |
| March 2010 |
Final approval received from the International Maritime Organization (IMO) |
| May 2010 |
Certificate of Ballast Water Management Systems (Type Approval

|
*3: Ballast water management convention |
| |
An international convention for the regulation and control of ships’ ballast water and sediments, for the purpose of preventing the movement of aquatic organisms and pathogens harmful to the environment, human health, and/or economic activity. The official name of the convention is the “International Convention for the Control and Management of Ships’ Ballast Water and Sediments.” Although adopted in 2004, the convention has not taken effect at the present time. |
*4: Chemical agents |
| |
The JFE BallastAce system uses the following chemical agents, which were developed by Toagosei Co. Ltd. |
| Biocide: |
“TG Ballastcleaner®” |
| Main ingredient: |
Sodium hypochlorite; used as a disinfectant for waterworks and pools and as a food additive. |
| Neutralizing agent: |
“TG Environmentalguard®” |
| Main ingredient: |
Sodium sulfite; used in producing food preservatives, dyes, etc. |
|
*5: Venturi tube |
| |
Device that separates bacteria from mud and sand and enhances the disinfecting power of the chemical agent by mixing/agitating the chemical agent and ballast water by power vortices generated by constriction/expansion of the piping passage. |
