Analysis and application of three-suction pipe foundation platform structure and towing stability

Abstract:Taking the typical three-suction pipe foundation applied in Bohai Bay as an ex ample, its structure towing stability, and foundation stability was calculated and analyzed.Based on it, the correspondence relationship between structure's floating weight and draft was derived, and provided a theoretical basis for the structural design and construction plan of floating.Meanwhile, the successful application instances of this typical structure in Bohai Bay in recent years are introduced in order to expand design ideas of minimum platforms and provide useful information for the application of offshore engineering technology in extreme shallow water.
