EAGLE-OCT.-API

EAGLE-OCT.-API is the API service, which enables you to use the program without a Web browser. The API service is developed based on the Web application EAGLE-OCT.-web. EAGLE-OCT.-web is a program providing ship form and ship performance data from their main particulars and enables an assessment of their performance in actual seas using OCTARVIA-web/API and SALVIA-OCT.-web/API.

EAGLE-OCT.-API is the API service, which enables you to use the program without a Web browser. The API service is developed based on the Web application EAGLE-OCT.-web. EAGLE-OCT.-web is a program providing ship form and ship performance data from their main particulars and enables an assessment of their performance in actual seas using OCTARVIA-web/API and SALVIA-OCT.-web/API.

This program allows users without having detailed ship geometry and performance data to assess the performance of their ships in actual seas. The analysis results can be utilized in connection with each company's business systems and data infrastructure. This also facilitates integration with existing systems and compatibility with each company's specific formats.
