'CHIKYU', a deep sea drill ship, was delivered to the Japan Agency for Marine- Earth Science and Technology (JAMSTEC) in July 2005. Construction of 'CHIKYU', featuring the latest technology in this field, opens up a new era of deep sea drilling, with a scientific drill ship adopting the riser drilling method for the very first time in the world. This scientific drill ship was built for the purposes of clarifying long-time environmental changes in the earth, exploring life in the earth's crust, studying the mechanism of earthquakes and so forth, through investigation deep into the earth's core. This paper introduces the Hoisting Equipment, the automation of the Dual Elevator System, the Core Sampling System and the Drill Waste Mud Treatment System that form a part of the new technologies developed and adopted in the building of 'CHIKYU'. 'CHIKYU' is expected to start regular operations in 2007 as the principal drill ship in the Integrated Ocean Drilling Program (IODP). In the future, this ship intends to drill into the sea bed to a depth of 4000 meters. To realize this, it will be necessary to develop deep sea drilling technology incorporating new knowledge obtained from operational experience, as well as new technology from the Oil Drilling Industry. The construction of 'CHIKYU' is just the first step and further development will be necessary, in order to reach as yet unexplored fields of sub-sea research.
