Abstract

The present disclosure relates to a skid docking and anchoring system with couplings, comprising a docking structure ( 100 ), an interchangeable skid ( 102 ) and a coupling skid ( 104 ). The docking structure ( 100 ) is formed by welded plates comprising a back plate ( 302 ) and a front plate ( 300 ). In addition, the back plate ( 302 ) features a groove for vertical attachment to the riser balcony ( 106 ). The front plate ( 300 ) comprises at least two front handles ( 304 ), at least four keys ( 306 ) located in the central region of the front plate ( 300 ), and at least four coupling supports ( 308 ) at the bottom of the front plate ( 300 ). Additionally, the coupling skid ( 104 ) comprises a welded truss structure ( 500 ), four coupling pins ( 502 ) and a tool basket ( 504 ).

Claims
