For laying gas and oil pipelines offshore from floating structures under severe environmental conditions, various concepts were developed and made operational during the last ten years. For the North Sea area these concepts vary from conventional barges, ship-shaped hulls, small semi-submersibles to large, highly sophisticated semi-submersible pipelaying vessels. Already in the preliminary stage of the development extensive engineering and research work are to be done to estblish its optimal workability and to select the final concept. The workability of a concept is mainly determined by its motions and forces caused by wind, waves and current. To establish the hydrodynamic merits of a concept several mathematical methods as well as model techniques are available. (Se)
