RR347 - Review of the role of response forecasting in decision-making for weather-sensitive offshore operations

This report reviews the role of vessel response forecasting as an aid to decision-making for weather sensitive offshore operations, and reviews recent work undertaken by the industry and HSE. In an earlier HSE pilot study on response forecasting in 2000 and 2001, comparisons were made between forecast and measured motions of a number of FPSOs/ FSUs and semi-submersible drilling vessels operating in the North Sea. Findings from the HSE pilot study and an earlier BP pilot study are reviewed; methods used to predict vessel motion responses are summarised, and key sources on uncertainty and factors influencing response predictability are assessed. Potential applications of response forecasting in offshore operations are then reviewed, together with issues raised in discussions with potential users and providers of response forecasting services.
