| Abstract | ||||
| Bulk carriers are one of the three dominating merchant ship types together with grain and container vessels. Today, bulk carriers comprise about one third of the world fleet in tonnage terms. The demand for raw materials like coal, iron, copper, …etc., has increased considerably since the turn of the millennium. Moreover, the bulk carrier has specific nature due to the loaded bulk cargo’s parameters which may slosh, liquefy, shift...etc. The intact stability of bulk carriers is investigated, with respect to the latest regulations developed by IMO. The effect of loading conditions and types of cargoes on ship stability and cargo earning capacity are studied. It is found that in some cases of loading conditions with certain types of cargo we have to use ballast water to satisfy the new grain regulations. This will lead to a reduction in the cargo earning capacity of the ship. The study under consideration is very important from the economic point of view of the vessel’s operation. Ship’s owners and charters must know which type of bulk cargoes is more profitable in case they have a choice to carry different types of bulk cargoes. A computer program is developed to carry out the stability calculations. Firstly we should get the vessel’s lines plans drawings, then using these drawings to prepare the vessel’s tables of offsets. Using these tables of offsets and Model Maker Program, full model of ship’s sections at different stations and the general arrangement can be obtained. Take this model in the Auto Hydro program to do the different loading conditions calculations. A programing code is written and to be run to check the compliance with the intact stability criteria | ||||
