Japanese project launches onboard data monitoring system

Japan’s National Maritime Research Institute has released the results of a new vessel data analysis project, combining onboard monitoring data stored by the Ship Data Center (ShipDC) with information from the POLARIS ocean data service provided by Japan Weather Association (JWA).

Phase two of the Japan Maritime Cluster Collaborative Research on Evaluation of Ship Performance in Actual Seas project, named ‘OCTARVIA’, has been underway since March 2022, and included 21 participating companies, such as ship owners and shipyards.

As part of the project, a software program was developed for the analysis of onboard monitoring data, called SALVIA-OCT.-web V2, with its effectiveness to be tested and validated by the participants.

That application is now publicly accessible via the NMRI cloud service, both as a limited free version or a full paid version. Both versions are able to acquire the data required for their analysis by API, from ShipDC and from the POLARIS ocean hindcast database created by JWA.

SALVIA-OCT.-web V2 allows users to assess ship performance by analysing the relationship between ship speed, engine speed and engine output, using data filtering and wind/wave correction functionality to ‘clean’ collected ship monitoring data.

Where detailed hull data is not available, users can also connect with the existing EAGLE-OCT.-web and OCTARVIA-web tools from NMRI, linking those systems with the data available from ShipDC and JWA.
