High Strength/Stiffness Riser Joints

The riser joints currently used aboard D/V Chikyu are made of steel, but it’s very difficult to adapt steel riser joints to ultra-deep water (>4,000 meters) operations. At these depths, lighter and stronger materials need to be considered, such as carbon-fiber reinforced plastic (CFRP) riser joints.
