Abstract

A basic study for the development of Integrated Seakeeping Performance Evaluation System on board the ship

From a ship's safe operation point of view, it is very important to estimate the navigational safety in a seaway.

The seakeeping performance can be defined as the ability of a ship to go to sea, and to accomplish its missions successfully and safely even in adverse environmental conditions.

There are several factors presently adopted for evaluating seakeeping performance. But a hardware of the system considering all these factors has not been developed since some of them can not be measured by sensors.

In this paper, a synthetic method of evaluating navigational safety is developed by measuring the vertical and lateral acceleration.

An experiment by using real measuring carried out on board the T/S 'HANNARA'. The equipment was measured every 4 hours for more than 30 minutes the acceleration by accelerometer, analyzed its acceleration values and calculated navigational dangerousness.

As the results of this on board experiment, the system is carried conviction to be useful as evaluating seakeeping performance.
