Inclining Experiment

Overview

This feature enables a user to create a formal report following an 'inclining experiment'. Inclining experiments are undertaken in order to determine the amount of GM that exists with the vessel in any particular loaded condition. Additionally the position of the centre of gravity of the vessel can be determined, for example,, with the vessel in the lightship condition. These experimental results can be used to provide confirmation of design calculations and are part of the formal requirements, both for a new vessel and for one that has undergone significant modifications.

The major activities involved in undertaking an inclining experiment are in collecting weight and other in-harbour data on the current condition of the vessel, moving small fixed weights through controlled athwartships distances and recording the corresponding movements of pendulums that measure the corresponding inclinations of the vessel. This data, plus a record of the persons involved in undertaking and observing the experiment, constitute the bulk of the actual work. The inclining experiment report consists of a record of the data collected and the results of some very simple calculations.
