A similar pair of thrusters is located in skeg in stern of vessel. The 10,500-ton, 400-foot self-propelled drilling vessel, designed by Global Marine, Inc., will be used in the Deep-Sea Drilling Project in which cores of ocean bottom sediments will be recovered in water depths of up to 20,000 feet in Atlantic and Pacific Oceans. The project, funded by National Science Foundation, is managed by Scripps Institution of Oceanography, University of California, San Diego. Drilling operations are to commence in June of this year.
