ABSTRACT:
The present disclosure is directed to a method and apparatus for drilling rig mobilization and demobilization. The rig is assembled or constructed at a remote site. It is later taken apart and transported to another remote site or back to a staging point. The rig itself comprises a rig floor which is supported on a set of vertical rig legs which support the rig floor for movement between raised and lowered positions. An equipment module is preferably installed on the rig floor. It goes above the rig floor while other modules are attached under the rig floor and provide additional equipment and service space. The method involves the transportation of the rig floor, the legs, equipment module and other modules to and from the rig site by hover craft while riding on a top deck on the hover craft for lateral transfer and installation.
