General information
With the trend in the offshore industry into deeper and deeper water, pipe laying and cable laying has become a real challenge. Special designs of stingers have been developed to allow pipelaying from shallow to ultradeep water with the same vessel, using the S-lay methology. Also pipelaying from semi-submersible heavy lift vessels is performed using the J-lay methodology. Typically this type of operations is performed using Dynamic Positioning or Dynamic Tracking.

Services & Activities
The Offshore Department can assist in the testing and analysis of critical issues in the operation of these vessels, such as the motion response to waves, the resulting pipe and cable loads and the operability of the Dynamic Positioning system.
The Ships Department can assist in the analysis of the Seakeeping performance and Manoeuvring performance of cable layers and pipe laying vessels on transit.
The Trials & Monitoring Department can be involved in full-scale measurements of motions and loads of these vessels.
