【 摘 要 】

The sea floor drill rig MeBo (acronym forMeeresboden-Bohrgerät, German for seafloor drill rig) is a robotic drill rig that is deployed on the sea floorand operated remotely from the research vessel to drill up to 80 m into thesea floor. It was developed at the MARUM Research Center for MarineEnvironmental Sciences at Bremen University. The complete system – comprisingthe drill rig, winch, control station, and the launch and recovery system –is transported in six containers and can be deployed worldwide from Germanand international research ships. It was the first remote-controlled deepsea drill rig to use a wireline coring technique. Compared to drillingvessels this technology has the advantage of operating from a stableplatform at the sea bed, which allows for optimal control over the drilling process.Especially for shallow drillings in the range of tens to hundreds of metres,sea bed drill rigs are time-efficient since no drill string has to beassembled from the ship to the sea floor before the first core can be taken.The MeBo has been successfully operated, retrieving high-quality cores at the seabed for a variety of research fields, including slope stability studies andpalaeoclimate reconstructions. Based on experience with the MeBo, a rigis now being built that will be able to drill to a depth of 200 m.
