The background knowledge of jackup structures, current methods and procedures for moving and positioning of jackups practiced by the industry and related safety performance (analysis of accident records) are reviewed. Floating stability and motion response are identified as important factors contributing to fatal accidents and weather is found to be, in general, responsible for delays in ocean transit. An improved criterion is suggested for assessing the capability of jackup structures to be moved and positioned safely. This also includes the procedure for selection of towing power in order that a move not be unduly delayed by its mobility to make desired speed.
