摘要

The Japan Marine Science and Technology Center (JAMSTEC) has been, and is now promoting the "OD21" program (i.e., "Ocean drilling in the 21st century"). This is the first plan in the world to utilize deep-water riser-drilling technologies for scientific drilling. One of the important factors for the success of this program is the development of a high-performance drilling vessel. Since 1990, JAMSTEC has been continuing a technological study of a riser-drilling vessel for scientific studies with an operational capability in waters up to 4000m deep. It was decided to start the construction with a two-phase plan: a vessel with a riser operation for waters up to 2500m deep will be constructed in the initial stage, and then the vessel will be modified to a 4000-m depth capability. In the development process of the vessel, named Chikyu, many new technical developments have taken place, such as drilling/ coring equipment, a dynamic positioning system, etc. Thus, the Chikyu is expected to contribute to ocean engineering and other work, in addition to scientific advances.
