Development of a Non-Contact Power Supply System: Case Study of Multi-Stage Drill Pipe for Underwater Drilling

Introducing examples of overcoming difficulties arising from ultra-long-distance transmission and challenges such as simultaneous transmission of power and signals!

A project aimed at applying deep-sea drilling for scientific research, earthquake studies, and resource exploration is being advanced by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC). Until now, we have been relying on battery-powered electrodes loaded at the drill tip, but the need for frequent battery replacements has resulted in significant time and cost burdens, leading to requests for a solution. In response, our company has been conducting trials for three years and has finally reached a stage where we feel the possibility of realization. This document provides an overview of our progress, which can be found in the materials available for download below. [Contents] - Structure and operation of the riser system for deep-sea drilling - Methods and challenges of adding a power supply system - Principles of the power supply system - Methods of theoretical analysis - Verification of reliability, and more *We welcome individual visits. *We are looking for joint development partners. *For more details, please refer to the PDF materials or feel free to contact us.
