摘要

This paper provides the conceptual design results of lifting riser system for subsea mining. The objective of subsea mining is to develop sea floor Manganese nodules mine, which is expected from Clarion-Clipperton region off the west coast of Central America. The pilot test of subsea mining will be conducted in East sea of Korea at water depth 1,000m before real project. So this study is performed using metocean data of East sea of Korea. The riser system is divided six parts; steel pipe, flexible hose, flex joint, pump, buffer and miner. This paper focused on the dimensions of steel pipe, flexible hose, and flex joint. Properties of most of these equipments are similar to those of oil market products which has been already verified in operating field for long time. The specifications of other parts are assumed using the data of other subsea mining projects. The dimensions of these equipments are designed for proper subsea mining operation, and analyses are performed to confirm of riser operability and deployment.
