Background
Various offshore operations are restricted by the magnitude of the (relative) vessel motions.
Examples of such operations are:
• Float over installation
• LNG-offloading connect
• Lifting
• Helicopter landing
• Automatic UAV landing
In normal sea conditions this implicates that such operations can only be conducted in quiescent periods and that the go/no-go decision for such operations is critical and requires an advance and reliable estimate of vessel motions.
At present ship motions are estimated by human observations. Systems extrapolating ship motion history can only predict the motions some 10 seconds in advance.

Project objectives
The project objective is to develop, test and demonstrate a practical system to predict quiescent periods of ship and platform motions some 60 seconds in advance.
