Problems solved by technology

[0003] The traditional fairlead towing fixation is to connect multiple fairleads in each group in series and fix them to the lower floating body nodes of the semi-submersible platform with anchor chains. This connection method cannot withstand the environmental load during ocean-going towage. Underwater manual operation is required for offshore release, the operation procedure is complicated, the construction period is long, and the safety risk is great

Abstract

The invention discloses a quick release type semi-submersible production platform fair lead towing fixing device which comprises a fixing support and a release assembly, one end of the fixing support is arranged on a semi-submersible production platform, and the release assembly comprises a releasing part and a connecting part. One end of the releasing part is inserted into the other end of the fixing support in the direction perpendicular to the length extension direction of the fixing support so that a fair lead can be fixed to the fixing support, one end of the connecting part is connected with the other end of the releasing part, and the other end of the connecting part is driven through external force so that the releasing part can be separated from the fixing support. The fixing device is simple and rapid in disassembly and assembly process, simple in form and capable of effectively resisting large environmental loads in long-distance towing of the semi-submersible production platform, the fair lead can be rapidly released conveniently when the semi-submersible production platform is installed on the sea, and offshore installation operation and installation time are saved.

Description

technical field [0001] The invention relates to the technical field of offshore oil engineering, in particular to a fast-release semi-submersible production platform fairlead towage fixing device. Background technique [0002] The semi-submersible production platform is a conventional equipment for offshore oil development. Its structure generally includes an upper module and a lower floating body, and a multi-point permanent mooring system is often used. Among them, the fairlead acts as a guide for the permanent mooring system and can rotate freely during the service period of the platform, but it needs to be fixed when the semi-submersible platform is towed for a long distance to prevent structural collisions, and it must be released when it is installed at sea , to complete the permanent mooring of the semi-submersible production platform. [0003] The traditional fairlead towing fixation is to connect multiple fairleads in each group in series and fix them to the lower ...
