In order to design an Energy Saving Device (ESD), shipyards need to know the forces applied on the structure.
Objectives:
The objective is to develop a methodology able to evaluate the forces applied on an ESD in navigation conditions.
Methods:
From existing hydrodynamic potential codes, such as HydroStar, and tools developed by Bureau Veritas, the forces applied on an ESD have been evaluated and the methodology has been tested on a Pre-Swirl Stator structure.
Results:
The design process for an ESD has been described and tested including static analysis, dynamic analysis and fatigue analysis.
Conclusions:
The forces applied on an ESD can be estimated following a design process and a methodology developed in GRIP.
