By using a pre-defined procedure based on the subject ship’s particulars, inclining experiment or draft survey is carried out to find the real displacement of the ship. The results of this experiment or survey is gathered in a report and delivered to the customer or authorized body for approval.
Sea trial procedures are prepared to be used for measurement of the ship’s total performance and specific equipment’s working performance. According to these procedures general performance of the ship is measured by making experiments to test the speed, maneuvering (turning, zig-zag, bow thruster) capability, noise and vibration characteristics, fuel consumption level, etc. Additionally different types of tests are carried out to find out the working performance of the ship equipment such as main engine, generator, electrical switchboard, communication and navigation equipment, anchor. A sea trial report that contains the results of these tests is prepared and submitted for approval of relevant bodies.
