Overview

Background & Policy context

MCY is among the leading Italian producer leisure yachts. The main goal is to improve the sea kindness and comfort of the planning hulls in non calm sea conditions

Objectives

SOPHYA aimed to improving the performance in rough seas of planing hull boats. It experimented new forecasting techniques - optimization and measuring on a scale model and in reality the performance to improve seakindliness, safety and energy performance on wave of the planing hulls.
In the phases of the project, the following were used, analyzed and further developed:
- Advanced and efficient open source fluid dynamics simulation (CFD) tools;
- Free Form Deformation techniques for the high-level management of the geometric variations of the hulls;
- Forecast and retrospective data of wave motion in the real test areas;
- Tools for analysis and correlation of the data measured in the tank and in the real world.

Methodology

Many components of the optimization alogorithm of a planing hull yachts have been developed in the project:

  • The hull geometry is deformed with a specifically developed shape parameterization strategy in which the mesh for the CFD simulations is modified along with the CAD geometry of the hull.
  • The full order model based on finite volume approach allows to simulate the turbulent flow and consider the rigid hull motions in non calm conditions. High-fidelity solution are collected into a database.
  • Proper orthogonal decomposition with interpolation is applied to efficiently compute the solution of a parametric partial differential equations system, exploiting the precomputed solutions database.

Results

The experimental effort of the project results in validated simulation tools. The full optimization pipeline composed by shape parameterization, full order simulation and model reduction tools has been put to test to generate a new, optimized hull. After further validation through towing tank tests, the optimized hull will be put in production by MCY.
