The Glomar Explorer as a Deep Ocean Drilling and Coring Ship

In early 1977 Global Marine Development Inc. (GMDI) conducted a study for the Scripps Institution of Oceanography (SIO) and the National Science Foundation (NSF) to determine the feasibility of utilizing the GLOMAR EXPLORER for deep water scientific drilling and coring. The large physical size, the massive load handling capability and the large center well of the GLOMAR EXPLORER allow a great deal of flexibility for the incorporation of riser and BOP handling and storage, drilling equipment, laboratory and shop spaces, bulk storage and crew accommodations. Of particular interest is the proposed incorporation of a riser which does not need flotation since the bare riser weight can be supported, raised and lowered from the ship´s existing gimbal and heave compensated rig floor. This capability simplifies and improves the safety of overall riser handling and support.
