ABSTRACT:
Wellhead and welder protector comprising an easily erected, temporary shelter designed to envelope a wellhead and the immediate surrounding area of either a production platform, well bay area or jack up rig "texas deck", for providing an optimal environment for welding, heat treatment, and similar processes. The overhead protection means can be in the form of a horizontal, planar surface comprised of aluminum, galvanized sheet metal, thick fabric or the like, supported via telescopic support means above the wellhead for providing overhead protection for its occupants from overhead falling objects and liquids. Self contained ventilation means for the removal of any toxic fumes and gases associated with welding and related processes is also included. Additionally a new and unique framing system associated with the protection means is used, comprising telescoping support members attached directly to the wellhead to provide ample room in the shelter; the configuration and design of the shelter is such that it is able to withstand the harsh weather such as tropical storms and the like, associated with the offshore drilling environment, yet is lightweight, sturdy, and easily assembled and disassembled.
