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 - Consideratons 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.

Prevention of Air Pollution -Protecting the Atmospheric Environment-

We received awards for Vessel Speed Reduction Program from both the Ports of Los Angeles and Long Beach

Kawasaki Kisen Kaisha, Ltd. (“K” LINE) is honored to have received recognition from the port authorities of Long Beach and Los Angeles, both in the United States, for recording high level of compliance throughout 2020 with voluntary speed reduction by “K” LINE’s car carriers and dry bulk carriers in the two ports’ respective programs in order to reduce coastal air pollution by slowing ships within the designated water. Ships participating in the program are asked to comply with speed limit of 12 knots within 40 miles (about 74 kilometers) from the coast of each port in order to reduce emissions of exhaust gases containing nitrogen oxide (NO_{X}), sulfur oxide (SO_{X}), particulate matter (PM) as well as CO_{2} that cause (global) warming from ships. We have long participated in the program aggressively, and as a result of this year’s achievement, “K” LINE has been honored to receive this award from the Port of Long Beach for 16th consecutive years since 2005 and from the Port of Los Angeles for 13th consecutive years since 2008 when their awards were commenced, respectively.

Efforts for development of next-generation technology for clearing NOX Tier III regulations

Movement to control NO_{X} (Nitrogen Oxide) discharged from ships is becoming active worldwide. Therefore, IMO (International Maritime Organization) is going to tighten the regulations significantly for new ships in or after 2016 (Tier III regulations).
“K” LINE installed a selective reduction catalyst device (SCR device) adapted to the NO_{X} Tier III regulations to diesel engines for power generators of large containerships that went into service in March 2013 in collaboration with Japan Marine United Corporation and DAIHATSU DIESEL MFG. CO., LTD, conducted an assessment for about a year and a half, and confirmed that the device worked alright on actual ships.
SCR is a technology of binding ammonia (NH_{3}) and NO_{X}, the gases hydrolyzed by heat of the exhaust gas, by spraying urea water used as reduction agent to thereby convert the gases to nitrogen gas (N_{2}) and water (H_{2}O).
“K” LINE is going to implement operational testing of the exhaust gas recirculation device (EGR device) adapted to the NO_{X} Tier III regulations in collaboration with Japan Marine United Corporation and Kawasaki Heavy Industries Ltd. as well.
EGR is a technology of reducing oxygen concentration at the time of combustion by sending a part of the exhaust gas again after purifying it and lowering combustion temperature to thereby reduce NO_{X}.
We will install the EGR device on the DRIVE GREENHIGHWAY which was completed in February, 2016, and are conducting experiments on actual ships for about two years and from now on.
We are not merely clearing the regulations, but also striving for green hull maintenance with no air pollution, and we are working to develop new technology and put it into practice in collaboration with marine engine manufacturers and shipyards.

We are working on unique decelerated navigation in Ise Bay and Mikawa Bay in Japan

We voluntarily reduce the speed of our car carriers to 12 knots or less when navigating in Ise Bay and Mikawa Bay as our own effort. This enables us to reduce the impact of ship navigation on the surrounding atmospheric environment, both on land and at sea. We also control emission of PM (including soot) while ships are in harbor by removing soot from the boiler before entering the ports. After entering the ports, we assure that the load on the electricity generator is appropriate to maintain a good combustion state.

Efforts at Port of Long Beach in North America

We have facilities for supplying electricity from land (6,600V/60Hz) to ships anchored at the self-managed container terminal in the Port of Long Beach. The electricity is converted to 440V onboard a ship, making it possible to supply all power to be used by ships in harbor. This enables stopping diesel-powered generators of ships in harbor and reduces exhaust gas to zero, improving the atmospheric environment in the surrounding area.

Efforts at Port of Bergen, Northern Europe

Port of Bergen, Norway implements the project which aims to reduce air pollution at the harbor by installing shore power supply equipment and using it when in harbor. This project enables the berthing vessels to stop their generators. Two offshore support vessels of K Line Offshore AS (KOAS) of our group company participated in this project. It is expected that this activity will reduce NO_{X} (nitrogen oxides) emission during the stay port by about 113 kg per day.

Water emulsion fuel and its properties

Water emulsion fuel is a mixture of fuel oil and water that has been agitated to disperse minute water particles within the fuel oil. Water emulsion fuel for diesel engines has been found to result in an approximately 20% reduction of nitrogen oxide (NO_{X}) contained in the exhaust gas. We are undertaking a verification test of equipment for using water emulsion fuel by installing it in ships operated by the “K” LINE Group.

Combustion reaction of water emulsion fuel

Combustion reaction of the water emulsion fuel is illustrated below.

 

  • The water particle is contained in an oil particle.
  • When the water emulsion fuel is injected into the engine, the water evaporates before the oil particle is ignited.
  • Evaporation of the water causes the fuel particle to disperse into even smaller particles.
  • The extremely small particles of fuel are highly combustible, so the probability of perfect combustion increases.
  • Combustion efficiency is improved, resulting in cleaner exhaust gas.
