After delivery, deterioration in vessel performance begins. This deterioration occurs in three main areas; exterior hull conditions, propeller condition, and powerplant performance. Depending on many factors, the deterioration of each of these items may be rapid or slow. In general, they will be independent of one another although they may occur simultaneously. A ship performance analyzer (SPA) has been designed to automatically collect data which facilitates evaluation of these individual elements. The analyzer is a microprocessor-based data-analysis system whose product is ship speed, rpm, horsepower, thrust and fuel rate. Comparison of this fundamental data with previous similar data provides a continuing evaluation of vessel performance. Knowledge of performance deterioration permits early detection of serious operational problems and enables timely drydocking for preventive maintenance.
