The 3rd Mid-Term Plan
Through the research described below, the NMRI aims to contribute to a substantial reduction in the number of marine accidents and to the construction of advanced safety standards.
Integrated analysis of entire ship load structure by NMRI-Design
Example of the development of a design support tool

During fiscal 2013 too, in addition to finalizing the fw calculation guidelines and continuing to contribute to IMO discussions, through the above-mentioned research and development we will be enhancing ship design and developing energy-saving devices in order to improve EEDI values, as well as developing energy-saving navigation technologies aimed at SEEMP improvement.
- Development of a simulator for navigational performance assessments in consideration of the characteristics of main engine.
- Development of a CFD system (NEPTUNE, SURF, etc.) which makes it possible to assess the performance of energy saving devices, etc. in actual seas in the design stage
We are developing basic technologies for CO2 emission reduction technologies
- Devices with high energy saving performance in actual seas using stern streamline control technology (WAD: Weather Adapted Duct, etc.)
- SEEMP improvements through energy-saving navigation technologies, etc.

EEDI (Energy Efficiency Design Index): differentiates the fuel consumption performance of vessels through the indexation of the efficiency of ships of new construction at the design/construction stage as“ the number of grams of CO2 estimated to be emitted when one ton of cargo is carried a distance of 1 mile, under certain set conditions”.
▶We are developing an offshore unloading operation simulator for offshore natural gas production systems, and a total safety evaluation technique.
▶We are undertaking the technical development of a subsea (extraction/lifting) system for use in the development of sea floor hydrothermal deposits, and the development of a safety assessment technology for its operation.
The world’s first successful test mining of sea-floor hydrothermal deposit, using elemental technology mining test equipment developed jointly with Mitsui Miike Machinery Co., Ltd. (Part of the project to develop sea-floor hydrothermal deposits being undertaken by the Japan Oil, Gas and Metals National Corporation (JOGMEC))
▶We are developing a tool enabling advance assessment of policies such as activation of coastal feeder transport, etc., and an assessment program for links between the oceangoing shipping network and coastal feeder routes.
Example of domestic feeder route link evaluation
