Abstract:
An exemplary method for a marine vessel having a propeller mounted to a rotatable shaft for converting rotative shaft power transferred from the shaft to the propeller into thrust to propel the marine vessel across water, includes obtaining measurement values that are descriptive of the shaft power, the thrust and speed through water of the marine vessel; separately estimating at least one of first excess shaft power caused by fouling of the propeller and second excess shaft power caused by fouling of the hull of the marine vessel; and issuing an indication of propeller cleaning in dependence of the first excess shaft power and hull cleaning in dependence of the second excess shaft power.

Claim (Index 27):
A diagnostics system for estimating operational efficiency of a marine vessel that employs a propulsion system including a propeller mounted to a rotatable shaft for converting rotative shaft power transferred from the shaft to the propeller into thrust to propel the marine vessel across water, the diagnostics system comprising:\n a plurality of sensors, each arranged to measure a respective characteristic of marine vessel operation, said sensors including a thrust sensor configured to measure thrust generated by a propeller, a torque sensor configured to measure torque in a shaft, a rotational speed sensor configured to measure a rotational speed of a shaft, and a speed sensor configured to measure speed through water of a marine vessel; at least one processor and at least one memory including computer program code for one or more programs, the at least one memory and the computer program code being configured to: obtain measurement values from said plurality of sensors, including measurement values descriptive of shaft power, thrust and speed through water of a marine vessel; estimate, based on said measurement values, at least one of first excess shaft power caused by fouling of a propeller and second excess shaft power caused by fouling of a hull of a marine vessel, wherein the system is configured to carry out an estimation of the first excess shaft power separately from an estimation of the second excess shaft power, the estimating including at least one of the following: estimating the first excess shaft power in dependence of shaft power and thrust at a first moment of time in view of the speed through water of the marine vessel at the first moment of time and further in view of shaft power and thrust specified for said speed through water in a first predefined reference condition, and/or estimating the second excess shaft power in dependence of shaft power and thrust at a second moment of time in view of the speed through water of the marine vessel at the second moment of time and further in view of thrust specified for said speed through water in a second predefined reference condition; and issue at least one of an indication concerning propeller cleaning at least in dependence of the first excess shaft power, and an indication concerning hull cleaning at least in dependence of the second excess shaft power, said issuing including: issuing the indication concerning propeller cleaning in response to the first excess shaft power or a value derived therefrom exceeding a first predefined threshold value, and/or issuing the indication concerning hull cleaning in response to the second excess shaft power or a value derived therefrom exceeding a second predefined threshold value.
