Abstract:
An exemplary method is disclosed for estimating operational efficiency of a marine vessel with 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 method including obtaining a respective time series of values for operating parameters of the marine vessel; constructing a multi-dimensional power matrix for a first time period based on operating parameter values within a respective sub-series thereof that represents a first time period; computing, for one or more propulsion parameters, fouling values based on information stored in the power matrix and information stored in a base matrix, of a reference fouling level; and creating indications concerning operating status of the marine vessel in dependence of the fouling values.

Claim (Index 31):
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 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, with the at least one processor, cause an apparatus to: obtain a respective time series of values for a plurality of operating parameters of a marine vessel, including at least:\n a respective time series of values for one or more propulsion parameters including at least the shaft power usage, \n a respective time series of values for one or more primary operating parameters including at least speed through water of the marine vessel and average draught of the marine vessel, and \n a respective time series for zero or more secondary operating parameters; \n construct a multi-dimensional power matrix for a first time period based on operating parameter values of said plurality of time series within a respective sub-series thereof that represents said first time period, where in the power matrix:\n a value of a given operating parameter defines a cell position along a dimension of the power matrix that represents the given operating parameter, a combination of the operating parameter values at a given time instant uniquely defining a cell position within the power matrix, and \n each cell of the power matrix stores a number of occurrences of the cell-position-defining combination of operating parameter values within said time period; \n compute, for each propulsion parameter, a respective one or more fouling values based on one or more representative propulsion parameter values derivable based on one or more respective subgroups of cells of the power matrix in comparison to respective one or more propulsion parameter values derivable based on a corresponding subgroup of cells of a base matrix, wherein the base matrix has a structure similar to that of the power matrix, where each cell of the base matrix stores the number of occurrences of the cell-position-defining combination of operating parameter values so that the cells of the base matrix jointly represent a reference fouling level of the marine vessel; and create one or more indications concerning operating status of the marine vessel at least in dependence of said fouling values.
