Future program of ocean research drilling use of GLOMAR EXPLORER

The scientists involved in earth science research and study have defined the task to explore the deep ocean margins and basins in 12000 to 14000 feet of water by drilling into the earth to obtain cores beneath the oceans to approximately 20000 feet. This task will require a large drill ship, a 12000-14000 foot riser and well control system and 35000 feet of drill pipe. The Glomar Explorer can be modified from a heavy-lift type mining ship to an oceanographic research drilling vessel. The ship can maintain position for deep water drilling for the oceanographic conditions specified. The unique heave-compensated gimbal system has the potential of allowing the support and tensioning of the riser without the requirements for riser floatation. Storage requirements are more than adequate, as are the space needs for the laboratory, crew and scientific staff. The ship can operate and handle 12000-14000 feet of riser and 35000 feet of drill pipe. The ship could qualify for an ABS-Class A operation with some modifications.
