This paper illustrates the significance of lift dynamic aspects observed during two major offshore heavy lift operations performed in 1991. Extensive offshore measurements provided further knowledge related to the dynamic behaviour of heavy lift systems offshore. The contribution of lift dynamics to the overall response in the medium frequency range was found to be of similar magnitude as the response in the wave frequency range. Initial correlation studies with computer models show that this aspect was underestimated by the analyses.
