Integrated decision support approach for ship design

Abstract

This paper presents a simulation based benchmarking methodology for evaluation of ship designs. The approach utilizes hydrodynamic calculations to obtain correct powering and speed values in waves, hind-cast weather data, and a detailed mission profile. This information is combined in a simulation model to produce a detailed and realistic operational profile of the design. The operational profile is then aggregated into a set of key performance indicators, to enable easy comparisons of different designs. The main advantage of this methodology is that is provides detailed and realistic operational profiles of ship designs at an early stage of the design process without using expensive methods such as CFD or model tests.A simple test case is presented to show how this methodology may be used in practice to capture differences in performance between two similar ship designs. Further, the test case shows how these differences may be presented in a manor that makes it easy to compare the performance of the ship designs.

Stochastic bivariate time series models of waves in the North Sea and their application in simulation-based design

“…Simulation-based approaches for studying maritime systems and entities has existed for some time. In the IDEAS project benchmarking of ship design concepts using hindcast weather data and discrete-event simulation (DES) is performed to enhance power requirement estimates [13]. HOLISHIP is an international research project working towards the development of a simulation-based integrated decision support system to cover all aspects of ship design [21].…”

Improving safety of navigation by constructing a dynamic model of the navigator's actions in the conditions of navigation risks

“…These automated systems are constantly evolving and adapting to changes in the maritime industry, technological innovations and regulatory requirements. As a result, they contribute to raising the level of professionalism of seafarers, improving their working and living conditions, as well as increasing the efficiency and competitiveness of maritime companies and the industry as a whole [7,8]. An important aspect of these systems is to keep information up to date and to innovate quickly, ensuring their longterm relevance and value to seafarers and employers.…”
