| Outline of Final Research Achievements |
We have developed a real-time analysis system integrated with drilling data acquired from the drilling control system on board the scientific drilling vessel “Chikyu”.
On the other hand, we have established the methods to estimate the motions of drill bit, characteristics of drilling formation, and stress exerted on the drill pipe using the drilling data. And by incorporating it into the system described above, we demonstrated the real-time simulations during operations, and confirmed its effectiveness.
To develop a drill pipe with built-in cable, we carried out simulations and fundamental experiments to understand the fundamental characteristics of multi-stage contactless signal and power simultaneous transmission. Furthermore, we conducted an preliminary experiment using full-scale actual drill pipe was equipped with a coil to observe the characteristics of multi-stage contactless signal and power simultaneous transmission in an actual operational environment.

| Academic Significance and Societal Importance of the Research Achievements |
海洋掘削において得られる限られた情報である掘削データの直接的な活用を図り、掘削データを活用したリアルタイム解析システムの基盤技術を創出したことは大きな意義をなす。
その中で、船上掘削データから掘削地点の情報であるドリルビット挙動や掘削地層特性を示唆する情報の創出を図り、その可能性を得た。
また、本研究で得た多段非接触信号電力同時伝送の基本特性は、本研究が対象としたケーブル内蔵ドリルパイプのみならず、他分野での活用が期待される。
