In light of our business outlook and various issues related to the global environment, we established a set of “Goals for 2050” and are making various approaches to this end.

 

To further reinforce this pathway, we set the target of “Continuing to avoid causing serious marine accidents” in the milestone year of 2019, which marks the 100-year anniversary since our foundation. 

 

Measures for Preventing Marine Pollution-Preventing Pollution by Oil and Waste-

Installing Overflow Pipe in Fuel Tank

When bunkering, if fuel is supplied to the fuel tank of our ship beyond capacity, there is a possibility of fuel flowing out of the ship through the air-vent of the fuel tank.
In order to prevent this situation, we have installed an overflow pipe in the overflow Tank in order that fuel oil spilt out of the fuel tank flows into the overflow tank, and furthermore, a flow detection sensor in the pipe or a high-level alarm sensor in the tank in order to detect overflow immediately.

Using Air Seal for the Stern Tube

We apply an air seal for the stern tube of our ships. An air seal is a device that continuously sends compressed air into the space in the section where the propeller shaft penetrates from the inside to the outside of the ship. This creates a sealed area inside the stern tube, which separates lubricating oil and seawater.

Use of electric powered deck equipment

We have introduced to our new ships electrically driven deck equipment, such as a mooring winch (*1) and a ramp way (*2) that used to be hydraulic powered equipment. This has eliminated the risk of leakage of hydraulic oil used for hydraulic driving.

*1 mooring winch: a device for winding up a rope or a wire to moor a ship.

*2 ramp way: a sloping path to be stretched to a quay when cars are loaded onto a car carrier ship and when they are landed. It is stored during a voyage.

Indirect Cooling System (Central Cooling System)

It is a device for cooling the engine and lubricating oil by indirectly exchanging heat with seawater via dedicated freshwater. Use of this system prevents leakages or overboard spills of lubricating oil due to trouble in the cooling system, because thermal exchange is not directly made between lubricating oil and seawater in this system.

Measures for Preserving Biodiversity-Considerations for the Ecosystem

We are promoting the use of environmentally-friendly paints.

When sea creatures attach to the hull, the resistance of the hull increases, and fuel consumption increases. This results in an increase in CO_{2} emission.
When those attached sea creatures are brought into other sea areas during  voyage, it will affect the ecosystem (of those areas).
Our company encourages adoption of low friction paint for new ships to reduce fuel consumption and prevent attaching of sea creatures, and are also trying to reduce CO_{2} emissions and maintain the biological diversity.
We also encourage use of low friction paint, as well as existing paint, for ships that are already in service.

We are managing ballast water properly

Ballast water, which is used to retain the stability of the ship, contains sea creatures and may make an impact on ecosystems in the areas where it is discharged. We are minimizing the impact by replacing ballast water in ocean areas having fewer creatures, while ensuring the stability and safety of ships. We are also studying ballast water treatment equipment, 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 of cement. On September 8, 2017, International Convention for the Control and Management of Ship’s Ballast Water and Sediments (hereinafter referred to as the Ballast Water Management Convention) entered into force. Until ballast water treatment equipment is installed, management of ballast water in accordance with ballast water exchange standards is required, but we will continue to appropriately enforce ballast water management in accordance with the rules, regardless of whether the new rule (regulation) is effective or not.

We will provide unchanged services even after the “Ballast Water Management Convention” enters into force

Considering these impacts of ballast water transport, “K” LINE promotes efforts to preserve biodiversity in order to maintain Marine life and ecosystems as they originally are.

The Ballast Water Management Convention was adopted by the IMO (International Maritime Organization) in 2004. Prior to this convention entering into force, we installed ballast water treatment equipment on large coal carriers with the cooperation of Nippon Kaiji Kyokai (Class NK). We are utilizing knowledge and experiences gained from this effort and actively and systematically implementing ballast water treatment equipment on new ships and existing ships. We will continue to respond to the needs of all our stakeholders while continuing to do business in a manner satisfying all regulations.
