Towing Performance and Influencing Factors of Integrated Wellhead Platform with Rounded Rectangular Bucket Foundation

For the development of an integrated rounded rectangular wellhead platform with a bucket foundation, a model test was conducted to study the towing motion response of such a structure under still water and wave conditions. The influence of various factors on the floating stability of the structure was investigated through alterations of the towing conditions (draft, towing point position, and wave conditions), and the related influencing mechanism was analyzed. Comparison and analysis were performed to determine the changes in the structure motion pattern and various effects of towing conditions on the structure during towing in still water and regular waves. Moreover, the influence of each factor on the structure's motion response during towing was analyzed using the Apriori algorithm. In addition, for the simulation of the towing process under actual sea conditions, a towing test was performed under irregular waves, and the stability of towing in irregular waves was compared with that in regular waves.
