양광시스템 실증실험을 위한 양광관 안전성 평가

Abstract

This paper provides analysis study of steel riser system for Subsea mining pilot test. The objective of subsea mining system is to develop sea floor Manganese nodule, which is expected to mine from Clarion-Clipperton region off the west coast of Central America. The riser system which is purposed on 2015 subsea mining pilot tests divided four parts : Steel riser, flex joint, pump and buffer. Motion of mining support vessel is re-calculated for verifying motion response. Properties of steel riser, pump and buffer are decided by KRISO. Properties of flex joint is designed for proper subsea mining operation, and analyses are performed to check operability of steel riser system.st of Central America.
