Since 1968, when the Deep Sea Drilling Project (DSDP) began its world-wide scientific drilling and coring operations aboard the D/V GLOMAR CHALLENGER, the project has been at the forefront of deep ocean technology exploring the geologic history of the earth. In August 1975, DSDP accepted a new challenge, the International Phase of Ocean Drilling (IPOD). Crucial to this new deep ocean challenge was the refinement of the project's deep water reentry hardware to permit penetration of the volcanic basement underlying the ocean floor. This paper covers the analysis, design and operation of DSDP's deep water reentry cone/dual casing hanger system developed in 1975.
