It is beneficial to perform a dynamic lifting analyses for safe and cost effective installation of subsea structures, for example, production templates, foundation bases and guide frames. A study combining experimental and theoretical approaches in simulating realistic conditions encountered offshore has been carried out to establish design and operational criteria for the main installation stages. Computer simulations using non-linear time domain software and laboratory model tests have been performed to investigate the influence of the following factors: sea state conditions, parameters of the structure, type of installation vessel and crane characteristics. Derived results and conclusions are intended for use during assessment of feasibility, planning and final engineering of installation operations.
