Japan’s National Maritime Research Institute has released a range of new software programs for analysis of vessel operations, developed by the OCTARVIA project carried out under the Japan Maritime Cluster Collaborative Research on Evaluation of Ship Performance initiative.
The project was carried out between October 2017 and March 2021, involving 25 organisations within the Japanese maritime industry. The new calculation programs were developed to evaluate ship performance in actual seas, validated through analysis of ship monitoring data, wind tunnel tests, and tank tests.
NMRI says it will open the software up to the wider industry via the NMRI Cloud service, in Japan and overseas, to support vessel performance improvement. Three applications are available, which can be used as either a limited free version of a full paid version.
OCTARVIA-web is used to predict ship performance in actual seas and evaluate life cycle fuel consumption, while SALVIA-OCT.-web offers analysis of ship monitoring data. EAGLE-OCT.-web can estimate hull form and calm sea performance from the vessel’s principal dimensions, with these calculations used as the input data of the other programs.
NMRI notes that users can apply the software to determine EEXI and CII figures for individual ships, analyse the influence of winds and waves on operating conditions, and evaluate operational plans such as route and maintenance by implementing the performance model in actual seas.
