hull dimensions - Opis:
- TEU number which the container ship is designed for, directly influences the main hull dimensions that is displacement D, length L, breadth B, draught T, their combinations and block coefficient delta. The main dimensions have a great impact on developing the ships resistant performance. Thus, it is really fundamental to establish the correct dimensions of the hull during the design and ship building process. Estimating the shape of the ships hull, that comprises its main dimensions, is one of the basic tasks as part of the preliminary design stage. The most significant decisions determining ships performance, its duration and building costs are made at the beginning of the preliminary stage, before the contract is signed, when the costs are relatively low, up to 4.5% of total costs of technical and working stage. The results of the decision that has been made at the preliminary design stage are significant for the new building ship including its building costs and what is more important, for the ship owner, the ships operational costs. It is important to limit the total ship resistance, for instance, by lowering the wave ship resistance as much as possible, especially when the operational speed and TEU number carried by one vessel is increasing. That resistance depends on the operational speed expressed by Froude number. The resistance criteria and the existing hull dimensions limits, resulting from ships route, must be taken into consideration bearing in mind safety conditions such as ships stability and seaworthiness, when the main ships dimensions are being determined.
