OCTARVIA Programs are updated to include calculation functions for alternative fuels
—OCTARVIA–web V2 and EAGLE–OCT.–web V2—

National Maritime Research Institute (NMRI), National Institute of Maritime, Port and Aviation Technology (Director General: Mr. Takemasa Minemoto) released the program for estimating the life cycle fuel consumption (OCTARVIA–web V2) on NMRI Cloud on March 28, 2025.

Also, the program estimating ship form and ship performance data from their main particulars (EAGLE–OCT.–web V2) is to be released on April 4, 2025.

OCTARVIA–web V2 and EAGLE–OCT.–web V2 have been developed through the Japan Maritime Cluster Collaborative Research Project on Evaluation of Ship Performance in Actual Seas(OCTARVIA).

The programs have been updated to include calculation functions for fuel consumption and greenhouse gas (GHG) emissions from main and auxiliary engines for alternative fuels such as ammonia and hydrogen. This enables the life cycle assessment of ships considering both economic and environmental aspects. NMRI continues to make its efforts to reduce GHG emissions from the shipping sector through global utilization of the programs.

In order to strengthen the international competitiveness of Japanese maritime industry, Japan Maritime Cluster Collaborative Research on Evaluation of Ship Performance in Actual Seas "OCTARVIA Project –Phase2–" was carried out from March 2022 to March 2024, as an open innovation platform. "OCTARVIA Project –Phase2–" has taken up the ship performance in actual seas as the research theme which each private company cannot conduct or maximize the research results.

In the project, the research body named 'OCTARVIA2', in which 21 companies such as ship owners and shipyards participated, was in charge of promoting social implementation. OCTARVIA 2 enhanced function of the current programs to estimate fuel consumption and GHG emissions from main and auxiliary engines for alternative fuels. In this way, the program for estimating the life cycle fuel consumption (OCTARVIA–web V2) and the program estimating ship form and ship performance data from their main particulars (EAGLE–OCT.–web V2) have been developed. Other improvements include improvement of accuracy of the added resistance in waves and the resistance due to drifting, considering future possible trend of slow steaming.

By releasing these programs on NMRI cloud(   https://cloud.nmri.go.jp/ ), NMRI continues its efforts to reduce GHG emissions from the shipping sector.

(Annex)
The programs can be used in the limited version (free version) and the full version (paid version).

  1. The features of the program and each data
    1. OCTARVIA–web V2 (released on March 28, 2025)
      • Users can calculate the speed reduction and the fuel consumption in actual seas by considering the effects of encountered wind and waves and can conduct life cycle assessment of ships considering aging and biofouling effects. Alternative fuels have been added to the fuel type used in main and auxiliary engines, making it possible to evaluate the ship performance not only from an economic aspect but also from an environmental aspect.
      • A calculation model for the resistance due to drifting and that for the added resistance in waves have also been improved to cope with increased drift angles by the wave effects and for slow steaming to reduce GHG emissions from ships.
      • Even such users as shipping companies who do not have detailed hull form data can evaluate the ship performance in actual seas by connecting this program with EAGLE–OCT.–web V2 and SALVIA–OCT.–web V2
    2. EAGLE–OCT.–web V2(to be released on April 4, 2025)
      • Users can estimate the hull form data such as the waterline shape, the cross-section, and the fuel consumption rate for alternative fuels by inputting the ship type (container ship, pure car carrier, bulk carrier and tanker) and principal dimensions. These data are required as the input for OCTARVIA–web V2 and SALVIA–OCT.–web V2.
      • Even such users as shipping companies and equipment manufacturers who do not have detailed hull form data can evaluate the ship performance in actual seas.
  2. Cooperation among each program and data
