Collaborative Research with External Organization

International

1. Securing safe marine transportation
Research on Structural Safety of Ships
We are developing the total system based on load and structural strength evaluation method and the cooperative hull monitoring system bywhich, the contribution to the safety ship operation, ship damage analysis and rational design rule making can be desired.

2. Preserving the marine environment
Research on Evaluation of Ship Performance in Actual Seas
For the purpose of creating a “scale” to accurately evaluate
the ship performance in actual seas, such as ship speed and fueloutput(kw)output(kw)revolution(rpm)consumption in winds and waves, OCTARVIA Project -Japan
Maritime cluster Collaborative Research- has been launched sinceOctober 2017.

speed(not)revolution(rpm)The participants are 25 companies; 3 shipping companies,
12 shipyards, 7 manufacturers, 1 weather consulting company,
1 classification society and 1 research institute.

speed(not)Analysis of on board monitoring data; output-revolution-speed

The project is managed in an open innovation scheme.
By means of the “scale”, construction and operation ofa truly high-performance ship in actual seas can be achieved.

3.Ocean development
Development of Evaluation Technologies for Safety and Performance ofOffshore Natural Resources Production System
NMRI is involved with technological development and safety assessment for exploitation and production of offshore natural resources
such as oil, gas and minerals.
In 2017, Japan Oil, Gas and Metals National

Corporation (JOGMEC) conducted the world's firstore-lifting pilot test for polymetallic sulphides, which
was sponsored by the Ministry of Economy, Trade andIndustry (METI), with great success under the sea near
Okinawa Island.

Wind Tunnel Test

We participated in this test with Japanese private
Feedercompanies to assess the operability and safety of the test.

Decision Support System for Collision AvoidanceNavigation :We are developing “Advanced Navigation Support System”,
a tablet-type voyage support device that shows safe navigation
courses by overlapping OZT (Obstacle Zone by Target), which isa measure of collision risk, with an image taken from a camera.
The tablet-type voyage support device, “Advanced Navigation SupportSystem”, is developed in a joint research project with Mitsui O.S.K. Lines,
Ltd., MOL Techno-Trade, Ltd., and Tokyo University of Marine Science andTechnology.
