Project for Ship Performance Evaluation in Actual Seas



A true high performance ship must have high propulsion efficiency in disturbances such as wind and waves, at the same time, must also guarantee safe navigation even in heavy seas. To develop a true high performance ship, it is necessary to satisfy the three basic ship performance requirements of propulsion, seakeeping and manoeuvrability in a unified manner, and to create new method of evaluating mission-oriented total ship performance in actual seas. In this project, we will develop technologies to evaluate total ship performance in actual seas using advanced water-basin experiment facilities.

Overview
Ship design support tool for performance in actual seas
HOPE
(Hull Optimization Program for Eco nomy)

Our program "HOPE" optimizes the principal ship dimensions and ship form considering the engine power and cost.
ESSPAS
(Estimation System of Ship Performance in Actual Seas)

Conceptual design and performance evaluation for ships with twin skegs and twin propellers
WAN (Weather Adaptive Navigation)
Our objective is reduction of greenhouse gas and also fuel consumption of ships. A new navigation system based upon weather forecast and ship performance in actual seas is now researching on. The system called WAN; Weather Adaptive Navigation, provides an optimum route with optimum speed of the ship.
Innovative numerical simulation technique
Fluid behaviour around ships is numericaly calculated by CIP method.
Cooperation with Propulsors Research Group
Pod Puropulsor
Propeller geometries and the fluid behaviour of pod propulsor are investigated to enhance the propeller performance. Sophisticated energy-saving devices such as contra-rotating propeller are also developed.
