Abstract

The invention relates to the technical field of ocean engineering accessory devices, in particular to a separating type underwater wellhead suction force anchor in efficient machining and transporting. Disassembling and installing are convenient, the production cost and the transporting cost are lowered, the structural stability and the sealing performance are improved, and a basic guarantee is provided for smoothly building a well. A suction force anchor barrel body with the top of a lower end opening sealed is included; the suction force anchor barrel body comprises separating type anchor barrel plate shell sets; every two adjacent sets of anchor barrel plate shells are sealed through a plurality of first rubber strips; the anchor barrel plate shells in each set are connected through positioning bolts; the top of the suction force anchor barrel body is provided with separating type sealing cover sets; the number of the anchor barrel plate shell sets is equal to that of the separatingtype sealing cover sets; every two adjacent sets of separating type sealing covers are sealed through a plurality of second sealing strips; and the two sets of separating type sealing covers are eachprovided with a water pumping hole.

Description

technical field

[0001] The invention relates to the technical field of marine engineering attachments, in particular to a separate underwater wellhead suction anchor for efficient processing and transportation. Background technique

[0002] As we all know, the suction cylindrical foundation is a foundation form with good development prospects in marine engineering in the past 20 years. Its inverted cylindrical structure with a closed top and an open bottom is placed in the seabed soil to provide mooring force for ships. It can be used as an infrastructure such as an ocean platform to maintain the stability of the platform. Suction anchors are easy to construct, safe and reliable to use, can be reused, and have better technical and economic characteristics. Therefore, they have received extensive attention from the ocean engineering community and have become a new type of offshore structural facility that is likely to replace the pile structure.

[0003] In recent years, wit...
