Spillage of cargo oil and fuel oil from ships damaged by collision or going aground can lead to serious pollution of the sea. Nissho Shipping has been actively ordering tankers of double-hull structure which, compared with single hulls, helps reduce the risk of oil spill from a hole in a wrecked ship. All the crude oil, product and chemical tankers it owns have double-hull structure.
Ship bottom coatings are used to prevent reduction of ship speed and increase in fuel consumption caused by corn barnacles and other shellfish sticking to the bottom. The International Maritime Organization (IMO) at its general assembly in November 1999 banned coatings containing organic tin. All the ships owned by Nissho Shipping now have tin-free (TF) coatings.
Plastics, combustibles and incombustibles in garbage from daily life on board are collected separately before disposal, just like on land.
Bilge (mixture of oil and water) generated in the engine room by ship operation is processed by bilge separator to remove oil. The removed oil is incinerated on board.
Nissho Shipping, in cooperation with an engine manufacturer, developed software for an electronically-controlled engine, and installed it in a product tanker completed in 2004 for the first time in Japan. The engine's fuel injection and exhaust are computer-controlled to achieve optimum combustion condition for the operation status, thereby reducing fuel consumption and emission of nitrogen oxides (NOx) and other hazardous substances.
To reduce emission of sulfur oxides (SOx), we use fuel with low sulfur content in accordance with the MARPOL convention.
To reduce fuel consumption and emission of carbon dioxide, Nissho Shipping takes such measures as adoption of a hull design to reduce resistance, cleaning of ship bottoms to reduce resistance, use of electronic charts and weather routing to select the optimum route, and adoption of an electronically-controlled engine.
Nissho shipping promotes protection of the environment in the head office, collecting wastes separately, promoting green purchasing, saving electricity, reducing copy paper, and disposing of wastes in accordance with the law and other related regulations.
