... the drilling rig. The major obstructions to removal of the drilling rig are the choke and kill lines; kelly shuck, and mouse holes. The choke line can be eliminated by routing through the front of the substructure. Placement of the choke manifold in front of the rig will also give room for a "blooey" line...

... is passing. They are made to make the fit-in process easier. Besides the term "scallop" also designations such as "cut-out" and "mouse-hole" are used for these details. Scallops are used in several types of welded structures with plate intersections such as ships, offshore structures, steel bridges, etc...

... drillstring components, riser pipe as well as casing and tubing. Doubles, Triples or even Quadruples of pipe are being made-up at special "Mouse-hole stations" including their own mechanized handling and make-up equipment. By this means, many functions such as prefabrication of stands of risers, drill pipe...

... with a Dual Pipe Handling System. The dual pipe handling system should allow simultaneously, to trip at well center and to make up stand of casings, drill pipes or drill collars in an auxiliary mouse hole. System allows to prepare and test tools (core barrels, down- hole motors), prepare BHA in advance during...

.... The pipe handling system includes two rotating mouse holes, a pedestal-type iron roughneck and a mechanized catwalk. However, in order to mitigate safety risks related to pipe handling habits of rig crew, enhance rig productivity and cut down non-productive time, a market survey was conducted to choose...
