TOKYO—Mitsui O.S.K. Lines, Ltd. (MOL; President & CEO: Takeshi Hashimoto) today announced that on May 30, a naming ceremony for the MOL-operated next-generation coal carrier was held at Oshima Shipbuilding Co., Ltd. (President: Eichi Hiraga; Headquarters: Saikai-City, Nagasaki Prefecture). This vessel will serve Hokuriku Electric Power Company (President: Koji Matsuda; Headquarters: Toyama-City, Toyama Prefecture), and she was named HOKULINK by Hokuriku Electric Power President Matsuda. President Matsuda, MOL Chairman Ikeda, as well as many other related parties attended the ceremony.

The name Hokulink is derived from the name of Hokuriku Electric Power Company’s regional membership services, called “Hokulink,” and represents a wish for growth of the Hokuriku region with stronger relationships in the region through operation of the vessel. It also represents a determination to strengthen cooperation with stakeholders including customers to ensure the growth of the business. As a vessel built especially for Hokuriku Electric Power, the Hokulink will transport coal from overseas, along with the Energy Prometheus, already in service, to contribute a stable and sustainable supply of electricity.

The Hokulink is the second vessel in the “EeneX” (Note 1) series of next-generation coal carriers based on the Japanese shipbuilding industry’s accumulated know-how and technology in development and construction of coal carriers, along with MOL’s expertise in operating these vessels. Adoption of a double-hull structure eliminated the need to fill cargo holds with ballast water, reducing the risk of marine pollution and minimize cargo contamination with salt and rust. In addition, the vessel is equipped with an SOx scrubber to reduce its environmental impact.

MOL offers the optimal “stress-free” transport service for customers and the environment, by achieving both safe and stable transport of an important energy resource for Japan.

(Note 1) [Main characteristics of EeneX]

  • Adoption of a double-hull structure
  • Adoption of semi-box shaped holds
  • Separating ballast water from cargo hold

EeneX expresses MOL’s intention to promote the spread of global energy (“ene”) by continually playing a part in coal-fired thermal power generation, combining “E,” which stands for the key words below in the development of the ship, with “X,” which conveys synergy.

(1) Efficient
