Abstract

The paper deals with a prediction procedure from which global wave-induced responses can be deterministically predicted a short time, 10-50 s, ahead of current time. The procedure relies on the autocorrelation function and takes into account prior measurements only; i.e. knowledge about wave conditions is not needed. In the present study, the procedure is examined on artificially simulated data that represents the measurements. It is shown that predictions, in most cases, can bemade fairly accurate up to 20 s ahead of current time; for longer periods ahead the accuracy reduces somewhat. The sensitivity to the amount of prior data is investigated.
