Introduce the Seawing
automatic kite system

 

The Seawing system adds natural wind energy to power a ship with a kite mounted on the ship bow. Operated from the bridge, in certain wind conditions the kite can be automatically extended to harness wind power to assist propelling the ship.

Optimal operation with
the K-IMS integrated vessel operation
and performance management system

The K-IMS system enables visualization of ship speed, output power, and fuel consumption in the crucial period just before and after docking. The system enables optimal operation by immediately and accurately  distinguishing a deterioration in performance and assisting in identifying
the cause.

Launch LNG-fueled car carriers
— Completion scheduled for 2020 —

 

We are strongly focused on improving the environmental performance of our fleet and are taking concrete steps to introduce LNG-fueled ships with support from the Ministry of the Environment and Ministry of Land, Infrastructure, Transport and Tourism as “a model business using alternative fuels to reduce ship CO2 emissions.”

At the 2030 Interim Milestone, we have set a new  target “Improve CO2 emission efficiency by 50% over 2008”. It surpasses the IMO target of CO2 emission efficiency by 40% over 2008.  In addition, we have obtained SBT certification from the SBTi (Science Based Target Initiative) as an emission reduction target which is scientifically consistent with the level achieving the Paris Agreement.  For more information, please click here.

Measures Against Climate Change -Aiming for efficient use of energy-

Ocean transport: a highly energy-efficient mode of transport

The amount of fuel consumed for transporting a ton of cargo over a distance of one kilometer is used as an index of energy efficiency. The smaller the (index) value is, the more energy-efficient the transport is. Ships are suited for transporting large volumes of cargo, and transport by ships with onboard large fuel-efficient diesel engines is the most energy-efficient among many modes of transport and is also effective for reducing CO_{2} emissions. To allow this efficient mode of transport to continue to exist in the future, we are committed to continuing to improve our ships energy efficiency by reviewing our operating systems to maximize the efficiency of our entire fleet, along with introducing ships with higher energy efficiency.

Use of heat energy of exhaust gas

The fuel combusted in the engine to be converted into energy for maneuvering the ship is discharged into the atmosphere as exhaust gas. The thermal energy of this high-temperature gas is collected by the exhaust gas economizer to generate hot, high-pressure steam. If the steam is sent to turbo generators driven by the steam turbine and used to generate electricity for use onboard, it enables saving fuel necessary for electrical generation. Thus, this system that uses energy of the exhaust gas, which would normally be wasted, improves a ships energy efficiency, or the transports energy efficiency, enabling reduction of CO_{2} emissions.

Use of energy from water stream generated by the propeller

The rudder that maintains and changes a ship's direction is positioned at the back of the propeller and is continually subject to the water stream that the propeller generates. Then, if a spherical bulge and horizontal fins are attached to the rudder, it enables converting the propellers water stream into propulsion power. Since the propulsion power increases, that extra power permits lower fuel consumption and reduces CO_{2} emissions, while maintaining the service speed of the ship.

Introduction of state-of-the-art autopilot

A ship is navigated to the destination port by following the course specified in the voyage plan. However, because a ship is subject to disturbances such as wind, waves and ocean current, she needs to be steered frequently to stay on course. An autopilot is a system that automatically steers the ship. It is used in areas where multiple ships do not converge, such as in mid-ocean. The latest type of autopilot is capable of learning the degree and duration of those disturbances and makes use of the data for the next steerage, thereby minimizing unnecessary operations. This reduces fuel consumption by about 1% compared with conventional units. We are striving to reduce the amount of CO_{2} emissions by continuing to install this state-of-the-art system in our ships.

We insulate heat to improve air-conditioner efficiency

Crew members onboard accommodations and the bridge for navigational watch are air-conditioned. However, ships are made of iron, which readily transfers heat, and subject to solar heat or outside temperature. This reduces the cooling/heating efficiency of air conditioners. We therefore use heat shield paint for outer plates of the accommodations and bridges to improve air-conditioning efficiency, and this reduces the electric power consumption needed for cooling and the amount of steam used for heating, which in turn means lower CO_{2} emissions.

Heat shield paint is highly effective for a car carrier because the areas of accommodations and upper part of the bridge are large.

We have introduced energy-saving transfer cranes

“K” LINE has introduced energy-saving hybrid transfer cranes at its own container terminals in Japan. These cranes, which are used at terminals to sort containers by destination, convert the energy generated when hoisted containers are set down in a pre-set location into electricity that is then reused as electric power. This cuts fuel consumption by about 40-50% compared to conventional cranes and greatly reduces noise.

Installation of Solar Panels upon constructing 2nd Warehouse of “BANGKOK COLD STORAGE SERVICE”

BANGKOK COLD STORAGE SERVICE, LTD, which operates in Bangkok, Thailand, installed solar panels on the roof of its 2nd warehouse in 2014. Output of the solar power system is up to 112.5kw, and total output in 2016 was 165mwh. This energy is equivalent to 13.9% of the annual electricity consumption at this warehouse and greatly contributes to energy saving. Further, BANGKOK COLD STORAGE SERVICE, LTD has been engaged in business operations in consideration of the environment since obtaining verification of ISO14001 in 2009.

Measures against natural disasters

We have established “Business Continuity Plan” to prepare for the event of natural disasters and second disasters. The Plan includes the continuation of important duties by having duties transferred to another internal or foreign location or pursued at home.

In addition, we accumulate backup data at some distant places so that electronic data will not be lost in the event of a disaster.

Furthermore, we provide weather conditions and stormy weather information on each route to our navigating ships, and also plan for minimization of damage by bad weather.
