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 “Building and implementing environmental flagships” in the milestone year of 2019, which marks the 100 year-anniversary since our foundation.

 

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 2016 with voluntary speed reduction by “K” LINE’s containerships, 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 12 consecutive years since 2005 and from the Port of Los Angeles for 9 consecutive years since 2008 when their awards were commenced, respectively. Especially, as to the Long Beach program, there were only two carriers including “K” LINE which recorded both more than two hundred calls at the port and more than a 90% compliance rate.

Recognition:

Port of Long Beach “2016 GREEN FLAG VESSEL SPEED REDUCTION PROGRAM”
(“K” LINE meets 99.22% compliance rate, totaling 257 compliant legs.)

 

Port of Los Angeles “2016 VESSEL SPEED REDUCTION PROGRAM”

(“K” LINE meets 100% compliance rate, totaling 61 compliant legs.)

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.

We are conducting cold ironing

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.
