Book Description
"This cost estimate has been prepared for a 12,000 foot drilling rig for use on offshore ice platforms during the winter and for land use during the summer. The basic rig price includes B.O.P. equipment for land application. The rig would be powered with AC diesel generators. The drilling motors would be DC and would be controlled through an SCR (silicon controlled rectifier) system. The rig would be transportable by Hercules aircraft, however the B.O.P. equipment would have to be partially disassembled before transporting by aircraft. The land rig and surface B.O.P. system costs are estimated at $5,200,000. A 70 man transportable camp would cost an estimated $490,000. The sub-sea B.O.P. system costs would be in addition to the basic rig costs. Like the land B.O.P. equipment it would have to be partially disassembled for Hercules transportation. A sub-sea system with a 1,500 foot operating capability is estimated at $2,140,000. A reduction of $125,000 is possible if the second sub-sea control pod and hose reel is eliminated. The cost of a complete rig equipped for drilling to 12,000 feet from land and ice platforms would therefore be: Rig and land B.O.P.: $5,200,000; Camp: $490,000; Sub-sea B.O.P. system: $2,140,000; Total: $7,830,000"--Leaf [1].
