Abstract

When a ship gets an original list and a weight is to be vertically shifted or is to be suspended by a ship’s gear two approaches for calculating the change in list of the ship have been developed as follows the first one—for the case when the biggest list of a ship is not more than 5–6° and the second one—when the biggest list of a ship is not more than 10–12° These equations have been represented in dimensionless form and reviewed for different specific shapes of a ship’s sides circle tumblehome and wallsided ones For wallsided ships in order to simplify the procedure of calculating the change in list a graphical approach and corresponding nomogram has been proposed and designed The developed method and equations can be also used for calculating the change in list of a ship when heavylift cargo is just suspended by the ship’s own gear during heavylift operations
