IMPROVEMENT OF METHODS OF CONTROL OF THE HOISTING ANGLE DURING CARGO OPERATIONS WITH HEAVY AND OVERSIZED CARGOES ON SPECIALIZED VESSELS

Abstract

This article describes how to improve the methods of the lifting angle (Hoisting angle) control during cargo operations with heavy and oversized cargoes on specialized vessels (such as Heavy Lift). Authors suggested the approaches to improve standard procedure of loading operations on such vessels by using decision support system. This system executes monitoring and management of a number of vessel characteristics: quantity of ballast and its distribution in ballast tanks, heeling angle, metacentric height, hook load, boom outreach, windspeed and rolling period. Use of the proposed method for creating decision support systems during cargo operations with heavy and oversized cargoes on specialized vessels, will allow, with exciting equipment, to reduce risk, increase the safety of these operations, reduce economic costs by reducing the time of cargo operations.
