An American deep-sea drilling ship. Launched in March 1967. It is 122 meters long, with a 61-meter-high drilling derrick in the center. It has a displacement of 11,000 tons. It can drill about 6,000 meters deep into the ocean floor. To achieve this, it is equipped with a system that receives sonar waves from the ocean floor and operates four side thrusters and a main screw to keep the ship in a constant position, as well as a system that pulls up the tip of the drill and then inserts it back into the same hole. It was built with funding from the National Science Foundation for the JOIDES project, and was used in the international cooperative project IPOD.
