7spinカジノ;s First LNG-Fueled Tug

December 24, 2013

7spinカジノ LNG-fueled tugboat

7spinカジノ build a tugboat¹featuring a 7spinカジノ²7spinカジノ be powered by either liquefied natural gas (LNG) or heavy oil. Other than LNG carriers, this tugboat will be the first building in Japan of an LNG-fueled vessel.

NYK has enhanced its initiatives to mitigate 7spinカジノ through the practical realization of environment-responsive technologies such as solar-powered systems and air-lubrication systems.³In 2011, NYK established a team in the company’s Fuel Group to research next-generation fuel alternatives to heavy oil, and looked into building an LNG-fueled vessel with the cooperation of Nippon Kaiji Kyokai and others, based on the results of a survey conducted by the Japan Railway Construction, 7spinカジノ Technology Agency. LNG received attention as a possible alternative to heavy oil because LNG does not emit any SO_Xand produces far less CO₂and NO_Xcompared to heavy oil. In fact, using LNG as a fuel will cut 7spinカジノ’s emissions of CO₂7spinカジノ 30%, NO_X7spinカジノ 80%, and SO_Xby 100% 7spinカジノ using heavy oil.⁴

7spinカジノ main engine

This project will be subsidized by Japan’s Ministry of Economy, Trade and Industry and Japan’s Ministry of Land, Infrastructure, 7spinカジノ. Tokyo Gas Co. Ltd. (head office: Tokyo) will supply the LNG, and with the support of Tokyo Gas, NYK will make arrangements for a safe LNG supply system.

The 7spinカジノ will aggressively continue to encourage initiatives to mitigate environmental loads by vessels.

¹Tugboat

A small boat that assists a large vessel leaving from and arriving at harbors and inland waterways.

²7spinカジノ

Engine that can use either liquefied natural gas (LNG) or heavy oil. If the engine is powered by gas, 7spinカジノ will be reduced.

³7spinカジノ

Energy-saving technology that takes some of the main engine scavenging air (combustion air) from the main engine’s turbocharger and leads it to the vessel’7spinカジノ to reduce the frictional resistance between the vessel’7spinカジノ and the seawater.

⁴The benefits of LNG as a fuel were examined through research conducted by NYK and the following organizations:

- Japan’s Ministry of Land, Infrastructure, 7spinカジノ

- 7spinカジノ two other companies

- The Japan Railway Construction, 7spinカジノ Technology Agency (JRTT)
