Environmental Report

The NS United Kaiun Group has been performing the following measures to promote environmental protection.

1.Prevention of Global Warming

Global warming is said to be caused by greenhouse effect gases such as CO2. Vessels need to burn fossil fuel to run such as fuel oil, and these emit CO2-containing exhaust fumes. At present, the only effective way to reduce CO2 gas is to reduce fuel consumption. We take the following measures to reduce fuel consumption:

  • Use of energy-saving equipment and devices.
  • Improving propulsion performance by hull cleaning/polishing of propeller.
  • Reducting speed and planning best-route in accordance with changing situations.
  • Minimizing fuel consumption per transported unit with efficient shipping schedules and increased cargo loads.

2.Prevention of Air Pollution

Exhaust gases from ships contain nitrogen oxides (NOx) and sulphur oxides (SOx), which cause air pollution and acid rain. Regarding NOx, the diesel engine with power output of more than 130 kW must comply with NOx emission limits set forth in the relevant regulation. Every our new vessels are equipped with a new-model engine with low NOx emissions. Also, for SOx emission control, the sulphur content of any fuel oil used on board ships must not exceed 0.5%. We comply with SOx emission regulations by two methods: Using low-sulfur fuel oil and Installing SOx scrubber (exhaust gas cleaning systems).

3.Prevention of the Dioxins Generation

To prevent generating dioxin, incinerators capable of rapidly cooling the exhaust gas temperature to 200°C are installed in our all newly built ships.

4.Prevention of Ozone Depletion

Chlorofluorocarbon and halon are regarded as causes of ozone depletion. For our new ships, we have adopted freezing and cooling machinery that use a Freon substitute. New installation of halon fire-extinguishing systems has been prohibited since July 1992, and most of our ships are now equipped with CO2 fire extinguishing systems or high-expansion-foam fire extinguishing systems.

5.Proper Management of Ballast Water

In order to prevent the transfer of harmful aquatic organisms or pathogens in the ballast water carried by ships, it is managed by using a ballast water treatment system or exchange the ballast water in the open sea.

6.Proper Disposal of Onboard Waste

Various kinds of waste are generated by the crew living on board. Such onboard waste is thoroughly separated and collected as is done on shore, and is either burned on board or duly disposed on shore. For details , please refer to our NS United Report.
