Problems solved by technology
At present, the mobile platform adopts an independent riser structure, which has poor stability and will produce large deflection and deformation when it is impacted by waves. On the other hand, since each riser is independent of each other, it cannot support a long length It has an impact on the safety of the riser, so the riser protection device is designed to protect the riser and reduce the load on the riser

The invention discloses a lifting type marine riser protecting and supporting device. The lifting type marine riser protecting and supporting device comprises a plurality of parallel supporting assemblies, wherein any supporting assembly comprises two opposite supporting columns, driving parts are respectively arranged on the two supporting columns, a supporting frame is arranged between the two supporting columns, the driving parts are in transmission connection with the supporting frame, and the driving parts are in sliding connection with the supporting columns through limiting pieces; and a plurality of guide pipes and a plurality of fixing pieces are arranged on the supporting frame, the guide pipes and the fixing pieces are correspondingly arranged, marine risers are arranged in the guide pipes, and the fixing pieces penetrate through the guide pipes and abut against the marine risers. According to the lifting type marine riser protecting and supporting device, the influence of waves on the marine risers can be reduced when an ocean platform works, the marine risers are prevented from being directly impacted by the waves, the device is mainly used for protecting and supporting the independent marine risers when the self-elevating ocean platform works, each marine riser and the device are integrated, the marine risers are fixed and supported, and the wave load borne by the marine risers during operation is reduced.
Description
technical field [0001] The invention relates to the technical field of marine engineering, in particular to a liftable riser protection support device. Background technique [0002] Offshore platforms need to use risers to protect drilling equipment during offshore oil drilling and exploitation, so as to prevent drilling equipment and oil pipes from being affected by seawater. At present, the mobile platform adopts an independent riser structure, which has poor stability and will produce large deflection and deformation when it is impacted by waves. On the other hand, since each riser is independent of each other, it cannot support a long length It has an impact on the safety of the riser, so a liftable riser protection device is designed to protect the riser and reduce the load on the riser. Contents of the invention [0003] The purpose of the present invention is to provide a liftable riser protection and support device to solve the above-mentioned problems in the prio...
