Active Heave Compensated Drilling Rig (AHC800) Cruise KN167 -KN168A/B R/V Knorr
Abstract
The continental shelves are of obvious scientific and strategic importance. However, the ability to cost-effectively collect core samples of continental shelf sediments has been limited by technical difficulties. Many sites of scientific interest are too shallow to be drilled by large drill ships, such as the JOIDES Resolution, and they are too deep to be drilled economically from jackup platforms. DOSECC's AHC800 drilling system was developed to overcome these obstacles by building a small active heave compensated drilling rig that could be used from vessels of opportunity, in particular the R/V Knorr. Active heave compensated drill rigs are not readily available either in the scientific drilling inventory or in the commercial market. Our long-term goal is the development of an active heave compensated drilling rig (AHC800) that can collect core for scientific study from the continental shelves. We have addressed our long-term goals through incremental improvements and two sea trials of the system. This report covers the second of these sea trials.
