Hull, Propeller, Engine and Fuel Trending

Isolate the cause of performance degradation and quantify changes over time.

In BMT SMART^SERVICES, five Performance Coefficients have been developed to trend the performance of the vessel, each with its specific use. Industry standard hydrodynamic methodology is used in the formulations of the Performance Coefficients giving optimal distinction between the components.

• Power Coefficient

Increased power absorption, due to the effect of fouling on the ship’s hull or propeller for example, is directly reflected in an increase of the power coefficient.

• Hull Coefficient

Provides a measure of changes to the hulls condition due to fouling, for example, over time.

• Propeller Coefficient

Isolates the performance of the propeller and indicates the propulsive efficiency of the propeller.

• SFOC (Specific Fuel Oil Consumption) Coefficient

A measure of the fuel consumption of the main engine is a direct indication of engine efficiency.

• FOC (Fuel Oil Consumption) Coefficient

Highlights the overall changes in fuel consumption and is an indication of total vessel performance.

In order to monitor the performance of a vessel and to indicate how much additional power, or fuel, is required as a consequence of the combined effects of weather and fouling or of the isolated effects of fouling on the hull or propeller, for example. Analysis enables data trending which can be used to optimise the scheduling of maintenance events and can be subsequently used to quantify the effectiveness of any such events.

How are Performance Coefficients Used?

Within SMART^ACCESS users have the ability to perform data analysis through the Benefit Analysis Module. The data can also be filtered, to limit the operational envelope for analysis. The results provide clear performance trends and can be used to demonstrate changes in performance over time. This is particularly useful when trying to quantify the effects maintenance events such as a hull scrub or propeller polish.
