Design of Software for Calculation and Analysis Engine Propeller Matching

Abstract

The criteria of a good ship are not only could floating in the sea, but it should have a very complex construction development planning. Longitudinal and transversal strengths, stability, flood, bulkhead, ship motion etc. were interrelated criteria that should be calculated for safety and comfort of the ship, passenger and cargo passenger. Matching point is an operating point of main engine same with the load character of propeller. In another word, the operating point of main engine rotation, where absorbed power by propeller is equal by produced power by main engine, and delivery equal speed with planned service speed. One step in ship design evaluating is EPM ("Engine Propeller Matching"). The lack of available software to analyze relationship between characteristics of propeller with main engine and hull, causing the calculation of EPM (Engine Propeller Matching) takes more time. Java is a very popular application, especially for enterprise application. So, that Java applications can be used to build a programming language of Engine Propeller Matching.
