PhD - Simulation Based Design of Ships With Regards to System Performance

Research topics

The purpose of the PhD research is to provide knowledge regarding the validity of simulation models for application in ship design. The research focuses on how simulation is applied to virtually test designs in operational scenarios.

Industrial goal

Knowledge that supports energy efficient design and operation of ships using simulation-based methods. The research focuses on techniques for implementing relevant operational scenarios for virtual testing of design concepts. Scenarios are created taking the operational decisions of ship owner and the ship master into account, thus making the research relevant for both ship owners and designers.

Achievements

A validation study towards estimation of fuel consumption and operational profile using GYMIR was conducted in the last quarter of 2017. The methodology and results are presented in a conference paper submitted to the International Marine Design Conference in Helsinki June 2018. 

Two papers have recently been submitted for review:
1. Operational sea passage scenario generation for virtual testing of ships using an optimization for simulation approach. Endre Sandvik, Jørgen Bremnes Nielsen, Bjørn Egil Asbjørnslett, Eilif Pedersen, Kjetil Fagerholt

2. Impact of simulation model fidelity on ship system evaluation in sea passage scenarios. Jørgen Bremnes Nielsen, Endre Sandvik, Bjørn Egil Asbjørnslett, Eilif Pedersen, Kjetil Fagerholt
