Introduction

This module is closely linked to the Strip module and currently only linearised motions can be predicted. The computation of ship motions is first prepared in Strip and the necessary inputs for the long-term statistics are added in this module.

Custom long-term seaway statistics may be applied or a database with Iacs Rec. 34, Issc, Rev. Nato Anep 11/14 or Söding [1] can be loaded. In addition, statistics can be generated for any location by requesting the relevant data from the Copernicus Climate Database.

In this module, ship routes can be planned and long-term statistics on these routes can be generated automatically. Figure 1 shows an example of a route.

Results

Figure 2 shows the probability of lateral (parallel to the deck) acceleration of two monitoring points. The gravity acceleration is included.
