Research on the installation process of suction piles under the ocean wellhead
This paper conducts an in-depth study on the installation process of the double wellhead suction piles in marine engineering.As there are no precedents for the installation of double wellhead suction piles,this study first reviews the installation process of suction foundations and single wellhead suction piles in marine engineering.Then,based on the structural characteristics and specific installation conditions of double wellhead suction piles,the corresponding process improvements are made.A complete set of installation processes for double wellhead suction piles is proposed,including factory prefabrication,ship loading and fixation,equipment debugging,marine transportation,lifting preparation,lifting,gravity penetration of suction piles,negative pressure penetration of suction piles,and recovery of construction machinery and equipment.The results of this study are of significant theoretical and practical importance for guiding actual marine engineering operations.
