Preserving Biodiversity

Mapping the relationship between the NYK Group and biodiversity

NYK have created the below map that shows the impacts on biodiversity of shipping through its lifecycle, and our related efforts, with reference to the "Map of the Relationship between Business and Biodiversity" developed by the Japan Business Initiative for Conservation and Sustainable Use of Biodiversity (JBIB). Recognizing our business activities could affect biodiversity in the entire lifecycle of sourcing, operating and dismantling ships, we will continuously take proactive measures.

Mapping the relationship between the NYK Group and biodiversity
  1. *1Dual rating system
    This system allows for the ideal power range to be selected for either high-speed operations or slow-steaming operations.
  2. *2MT-FAST
    This is a multi-blade device that can be attached to a ship's hull just in front of its propeller to catch the lost energy from the swirl flow generated by propeller rotation, improving propulsion efficiency while also saving energy.
  3. *3SPAS: Ship Performance Analyzing System
  4. *4SIMS: Ship Information Management System
  5. *5LiVE: Latest Information for Vessel Efficiency
    This system (portal site) aids ship managers in making decisions for realising optimal operation by tracking big data collected through our SIMS.
  6. *6VPAS: Vessel Performance Analysis System
    This software analyses vessel performance based on the various data collected from the vessel.
  7. *7Capt's DOSCA
    This system supplies vessels with up-to-date weather and sea condition forecast information.
  8. *8Ballast water management systems
    These systems ensure that the marine life carried along with the ballast water does not upset other ecosystems. Ballast water is seawater carried by the vessels to maintain their balance. Normally, tanks at the bottom of vessels take on ballast water at unloading ports and release it at the loading port.

Participated as a Promotion Partner of the "Declaration on Biodiversity by Nippon Keidanren"

NYK agreed with the declaration and participated as a "Promotion Partner" in December 2010 and also took part in "Japan Business and Biodiversity Partnership in October 2010. In line with the declaration and guidelines, we will conduct our business activities.

Declaration on Biodiversity by Nippon Keidanren (Summary)

  1. 1Appreciate nature's gifts and aim for corporate activities in harmony with the natural environment
  2. 2Act from a global perspective on the biodiversity crisis
  3. 3Act voluntarily and steadily to contribute to biodiversity
  4. 4Promote corporate management for sustainable resource use
  5. 5Create an industry, lifestyle and culture that will learn from biodiversity
  6. 6Collaborate with relevant international and national organizations
  7. 7Spearhead activities to build a society that will nurture biodiversity

Ballast Water Management to Preserve Biological Diversity

To prevent the cross-boundary movement of aquatic organism affecting the marine environment, in 2004 the IMO adopted the International Convention for the Control and Management of Ship's Ballast Water and Sediments. This convention entered into force in September 2017. Ahead of enforcement of the convention, the NYK Group began equipping its car carriers with a ballast water management system*1 that had received formal approval from Japan's Ministry of Land, Infrastructure, Transport and Tourism in 2010. In fact, 100 of NYK's owned and directly managed vessels had ballast water management systems as of the end of March 2019.

  1. *1Ballast Water Management System
    Seawater (ballast water) is used in ships to maintain ship strength and stability, but oceangoing vessels transport not only the ballast water but also the marine organisms within. A ballast water management system is a system that disinfects organisms and pathogens found within ballast water, using various treatment methods, to prevent the disturbance of an ecosystem.
