Considerations for the Eco-system

Promoting the use of environmentally friendly paints

When sea creatures attach to the hull, the resistance of the hull increases, and fuel consumption increases. It means the increase in CO ₂ emission.
When sea creatures which attached on the bottom of a ship are brought into other sea areas by voyage, it will affect the ecosystem.
Our company encourage to adopt low friction paint for reducing fuel consumption and preventing sea creatures from attaching to the bottom of a ship, try to reduce CO ₂ emission and maintenance of the biological diversity.
And also, we encourage to use low friction paint as well as existing paint (non-toxicity type silicon paint, polymer-based paint) to service ships.

Managing ballast water properly

Ballast water, which is used to retain the stability of the ship, contains marine life and may influence the eco-system in the area where it is discharged. We minimize the influence by replacing ballast water in ocean areas with less marine life, while ensuring the stability and safety of ships. We are also studying ballast water treatment systems, installation of which will be mandatory after the Ballast Water Management Convention comes into effect. Meanwhile, we are taking other steps to minimize the impact on eco-systems, such as the introduction of large containerships that use the smallest possible volume of ballast water and car carriers with fixed ballast made from concrete.

Promptly installing a ballast water treatment systems

Considering these effects of ballast water transport, "K" Line promotes efforts to preserve biodiversity in order to maintain marine life and ecosystems as they are currently.
The "International Convention for the Control and Management of Ships' Ballast Water and Sediments" (Ballast Water Management Convention)※, was adopted by the IMO (International Maritime Organization) in 2004. Prior to this convention going into effect, we have installed ballast water treatment systems on large coal carriers with the cooperation of Nippon Kaiji Kyokai.

 ※ Still has not gone into effect as of June 2013
