摘要

This study investigates the wet towing characteristics of an integrated wellhead platform supported by a bucket foundation. These characteristics are crucial for optimizing offshore construction efficiency and enabling the development of small marginal oil fields. The wet towing behavior of the integrated wellhead platform was explored through a combination of physical experiments and numerical simulations. Physical experiments were conducted to validate the accuracy of the numerical simulations. Subsequently, numerical simulations were employed to determine the impacts of towing speed and wave direction on the towing process of the integrated wellhead platform. Finally, the impact of compartment failure due to bulkhead damage on towage stability was analyzed. Findings indicate that the wave and towing directions influence the motion of the platform at various degrees of freedom. The platform demonstrates optimal stability when towing against waves, particularly when the towing direction aligns at a specific angle relative to the wave direction. In addition, a controlled increase in towing speed within a specific range effectively mitigates roll and pitch motions, which enhances the overall tow stability of the platform. Notably, compartment failure has an adverse effect on the towing stability, particularly in aft compartments. Therefore, it requires careful consideration and attention in practical engineering scenarios.
