en.Wedoany.com Reported - The National Maritime Research Institute (NMRI) of Japan, part of the National Institute of Maritime, Port and Aviation Technology, and Mitsubishi Shipbuilding Corporation, a member of the Mitsubishi Heavy Industries (MHI) Group, have initiated the integration of NMRI's "OCTARVIA" project with Mitsubishi Shipbuilding's power prediction and hull form selection system "MiPoLin®".

The OCTARVIA project includes the ship lifecycle fuel efficiency evaluation program "OCTARVIA-web V2.1" and the actual ship monitoring data analysis program "SALVIA-OCT.-web V2.2", released on the NMRI cloud on June 5, 2026. After integration, users can import hull geometry and performance data generated by MiPoLin® into the OCTARVIA project, enabling seamless execution of ship lifecycle fuel consumption estimation and ship performance evaluation based on ship monitoring data.

Under the OCTARVIA project, the program "EAGLE-OCT.-web" has also been developed to provide hull form and ship performance data based on principal dimensions, serving as an input support tool for OCTARVIA-web and SALVIA-OCT.-web. NMRI is working to enhance the functionality of these programs for social implementation.

In terms of technical implementation, NMRI has added integration with MiPoLin® to the previous version of the programs. This allows users not only to estimate hull geometry and performance based on ship principal parameters as before, but also to seamlessly connect ship databases and towing tank databases to the OCTARVIA programs, thereby achieving more accurate lifecycle fuel consumption estimation and onboard monitoring data analysis.

Mitsubishi Shipbuilding's "MiPoLin®" is a high-precision power prediction and hull form selection system, built on the results of over 1,200 towing tank tests at the Mitsubishi Nagasaki Towing Tank and data from more than 420 ship designs. It applies the technical capabilities of the MHI Group to address a wider range of maritime industry challenges.

Through this collaboration, NMRI and Mitsubishi Shipbuilding will promote the adoption of the OCTARVIA project and MiPoLin® to support greenhouse gas reduction efforts in the maritime sector.
