SPEED: A NEW SOFTWARE FOR SPEED & POWER SEA TRIAL ANALYSIS

Abstract

The last international recommended procedures and normative prescribe how the speed & power sea trials should be carried out and analyzed in order to evaluate the effective ship performances at the contractual load condition and keeping out the environment effect, that means wave, wind, current and water temperature. For this reason, CETENA recently developed the new software “SPEED” aimed to perform the analysis of the data measured during official S&P sea trials and to provide the final results just onboard as the sea trials have been finalized. In order to guarantee both the software development and the accuracy of computation that can be carried out, in summer 2018 the software certification has been completed in accordance with the rules ABS and RINA. The ship speed and power performance analysed and thus referred to ideal condition can be used for verifying the Energy Efficiency Design Index (EEDI) of the ship.
