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 find a way to handle data which varies, e.g. it is not the intention to treat a change in RPM as a spike in the data.

To handle the data as ―steady state in a time frame t it will be necessary to investigate the assumed variation of the ship’s movements, e.g. if the RPM are changed, which response time of the vessel is then the result.

This can be treated as a spike in data, which will create distortion in the resulting output from the model.

It is the intention to create a function to detect and remove disturbances in signals in order to create a consistent output from the system.
