General on Ship Design

Variant Designing in the Preliminary Small Ship Design Process

“…The ship design theory deals with issues relating to basic technical [1] and economic properties of the designed ship, which are frequently determined using optimisation techniques [2]. This mainly refers to parameters which substantially affect the cost of shipbuilding (and purchase), and the cost of ship operation [2].…”

“…This mainly refers to parameters which substantially affect the cost of shipbuilding (and purchase), and the cost of ship operation [2]. Ship designing is a complex process, as the ship itself is a complex, technical multi-level object which operates in the air/water boundary environment and is exposed to the action of many different external and internal factors resulting from the adopted technical solutions, type of operation, and environmental conditions.…”

“…A traditional ship design process consists of a series of subsequent multistage iterations, which gradually increase the design identification level. The initial design process stage, performed with the aid of the ship design theory, bears the name of preliminary design, or pre-design [3][4] [2]. In the next stages, the approximation obtained in the previous stage is subject to verification and, if necessary, correction.…”

Prediction of a Newbuilding Proce of the Bulk Carriers based on Gross Tonnage GT and Main Engine Power

“…Since ship design is a multistage process, at each stage design parameters are optimized relative to the criteria and design constraints, where economic analysis plays an main role. Appropriate conduct of this analysis is the basis for the development of ship design of highest operational values [3,4,5,6,7,8,11].…”

“…The preliminary design stage consists of parametric and geometric design phases [4,8,9,10,12]. The estimated price of newbuilding should be known at the preliminary design stage.…”
