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 and SALVIA-OCT.-web. This program allows users who do not have detailed ship geometry and performance data to assess the performance of their ships in actual seas.
