Hull Performance provides industry standard (ISO19030-2) benchmarking of hull and propeller performance.
The relation for the power needed to move a vessel through calm waters at a given speed will change over time. This is due to hull fouling, propeller deterioration, machinery wear and tear amongst others. This change over time is regarded the hull and propeller performance.
The vessel will also be subjected to waves, wind and current, making the hull and propeller performance estimation and evaluation even more complex. The Kongsberg K-IMS Hull Performance application takes advantage of the ISO19030-2 to provide an industry standard way of tackling these challenges.
The hull performance application will continuously log high frequency data from the vessel. Data are averaged over a 10 minute period, and the data and vessel must fulfil several reference conditions and data-quality requirements (ISO19030-2) for the data to be considered. This is done automatically by the application. Online high speed sampling provides a superior data confidence compared to traditional off-line methods. The application provides powerful visualization of occurrence of individual reference conditions. This allows easier identifying and addressing of specific sensor or data-gathering problems. The application leaves the user in full charge of defining, updating or deleting performance periods and events. Performance must be evaluated in conjunction with performance affecting events such as hull and propeller cleanings.
The fleet predicted performance view lets the user evaluate all vessels in the fleet at once, time aligned for a given event (i.e. propeller cleaning). This view also provides current performance indicators as well as future estimates for performance with time-to limit calculations.
