D/V Glomar Challenger. The 10,500 ton vessel is 400 ft. long, has a beam of 65 ft. and a loaded draft of 20 ft. She is owned and operated by Glomar Marine Inc. (GMI), of Los Angeles, under a subcontract with SIO. She is capable of conducting drilling operations in the open sea using dynamic positioning to maintain position over a borehole. Admidships is the drilling derrick which stands 194 ft. above the waterline. Below the derrick (not visible) is the 20 X 20 ft. center well ("moon-pool") in which is mounted the guide shoe and through which the drill pipe, bit and other tools are lowered and pulled up during drilling operations. Forward of the derrick is the GMI-designed auto matic pipe racker which normally contains 23,000 ft. of 5-inch S-135 drill pipe. Quarters for the crew and scientific staff are located aft, as are all scientific laboratory spaces
