Deep Sea Drilling Project. Dynamic Positioning.

摘要

It was the dream of oceanographers and marine geologists to recover sedimentary core material from deep under the ocean floor and his belief that a drilling research vessel could be dynamically positioned over a bore hole on the ocean floor that revolutionized the world of ocean sciences and global geology. This dream culminated in the highly successful Deep Sea Drilling Project and the remarkable D/V GLOMAR CHALLENGER. The technical report tells about the performance of the dynamic positioning system which has allowed D/V GLOMAR CHALLENGER to drill and core sedimentary material in water 20,000feet deep and 3,888feet into the ocean floor with an apparent plus or minus 40-foot excursion for four or five days at a time.
