Abstract

Tankers are one of the popular modes of transportation associated with liquid cargo. Efficiency with respect to the volume of cargo transported by tankers is an essential consideration in the transportation business process, especially fuel oil, which has become a benchmark for the global economy recently. Various studies have been carried out to optimize cargo space. This study aims to define the factors that influence cargo compartment efficiency to increase the effectiveness in the transportation business. In this study, it is known that the transverse bulkhead arrangement affects the payload capacity, which is related to the criteria in the naval architect principle. The hopper design also influences the optimization of cargo volume, which can provide benefits in terms of payload. Excess cargo volume on existing ships due to hopper design optimization, the future ship design can reduce the length of the cargo compartments that still meet the desired payload. Reducing the length of the cargo hold will undoubtedly provide an opportunity to optimize the scantling analysis for longitudinal and transverse ship structures. This study is expected to be a reference and a more detailed discussion regarding the efficiency of cargo space on tankers in the future.

Abstract

Indonesia, as an archipelagic country, requires the development of efficient and independent ship design technologies. This study aims to develop a B-spline-based computer aided design (CAD) program for modelling ship hull geometry from offset data and calculating basic hydrostatic parameters. The offset data are defined as fit points at each station and processed to determine the corresponding control points for generating B-spline section curves. The resulting station curves are then arranged along the longitudinal direction to form the hull geometry. Hydrostatic calculations are performed by evaluating the station curves, determining the submerged sections at a specified draft, calculating the submerged sectional areas, and integrating them along the ship length. The calculated parameters include submerged volume, displacement, Longitudinal Center of Buoyancy (LCB), Length of Waterline (LWL), and Waterplane Area (WPA). The developed program is validated using a ship model template from commercial software by comparing both hull geometry and hydrostatic results. The validation shows deviations under 0.2% for the simple curve test and under 0.35% for the hydrostatic parameters of the selected hull model. These results indicate that the developed program has the potential to serve as a local CAD alternative for preliminary hull modeling and basic hydrostatic calculations.
