The old school performance system is based on daily reporting by the ship’s crew (noon data).

The intention of the reporting system is that the crew sends in average values of parameters over a certain p

With relation to uncertainty in measurements of data it is necessary to analyse each sensor with respect to manufacture and type.

The manufacturer of the sensor provides information about the expected

The data used for the performance analysis:

may be with an interval i.e. 10 seconds. This interval is not sufficient to describe the full dynamics of all logged parameters in the system, and it therefore

Another method for detecting changes in a signal is based on change detection algorithms.

An expected behaviour of a system is compared to the actual behaviour and a change or a fault is detected by the

When setting up rules for removal of spikes it will be necessary to evaluate the mean and variance in a certain time frame.

If a spike is detected, it can be replaced by an interpolated value.

To identify

If the ship’s performance has to be simulated under all conditions it is necessary to find a method for running the series from point A to point B including series with variations over time.

It is needed to f

More than 20 parameters are logged through the ship’s automation system.

The timestamp for the logging has to be the same for each parameter in order to have the data logged at the same time.
