The platform DolWin alpha was experiencing unexpectedly high motions in the topside, even in moderate weather/sea conditions, which are having a detrimental effect on the platform's electrical equipment and may also result in premature fatigue damage.
The scope of work included a motion analysis of DolWin1 platform split up into two phases. In the first phase, measurements of the platform movements were taken and an analysis of the data was performed. Within the second phase, the achieved data was compared with the expected structural response of the platform derived from a dynamic structural model. The final step was to propose a technical solution to reduce the motions.
