Prologue
NORMALLY there are only two types of marine machines concerned with the discovery and recovery of oil from under the ocean floor. The first, mainly engaged in the discovery of oil, is a self-propelled vessel, sometimes of very considerable size. Apart from its towering drilling derrick, it is indistinguishable from any oceangoing cargo vessel; its purpose is to drill boreholes in areas where seismological and geological studies suggest oil may exist. The technical operation of this activity is highly complex, yet these vessels have achieved a remarkable level of success. However, they suffer from two major drawbacks. Although they are equipped with the most advanced and sophisticated navigational equipment, including bowthrust propellers, for them to maintain position in running seas, strong tides and winds when boring can be extremely difficult, and in really heavy weather operations have to be suspended.For the actual drilling of oil and its recovery – principally its recovery – the
