Description
Technical field
The present invention relates to hanging methods, more particularly to a kind of produce for offshore floating type to store up Unloading Device (FPSO) standpipe
Large size valve offshore lifting method.Belong to offshore oil chemical field.
Background technique
Currently, being promoted to the standpipe of offshore floating type production storage Unloading Device (FPSO), replacing rotary flange or dimension
When repairing valve, need to carry out disassembly lifting to valve body.Has huge stone since offshore floating type produces storage Unloading Device (FPSO)
Oil and gas production capacity, and its natural gas multi-purpose station pipeline size is generally large, pressure rating is higher, therefore, offshore floating type
Valve size and weight on production storage Unloading Device standpipe is also larger, and by taking 20 cun 2500 pounds of valve as an example, total weight reaches
To 43.5 tons, valve body weighs 27.5 tons.Since the length that offshore floating type produces storage Unloading Device can reach 300 meters, valve weight is again
Larger, general to install two stylobate A seating loop wheel machines at sea in floating production storage offloading, maximum safe working load is 25
Ton；And do not covered since offshore floating type produces the own loop wheel machine in partial region in storage Unloading Device, and offshore floating type production storage is unloaded
Have the Lifting Capacity that loop wheel machine does not have 20 cun of valves again on oily device by oneself.Therefore, it is necessary to be hung using large-scale floating crane to valve
Dress, still, using the costly of large-scale floating crane, the construction time is longer, larger by environmental influence.
Summary of the invention
It is a primary object of the present invention to overcome disadvantages mentioned above of the existing technology, and it is raw to provide a kind of improved floating
