Outline of Final Research Achievements

In the present study, the lifting system for subsea mining was focused. The mathematical model to estimate the pressure loss in inclined pipe during the slurry transport was developed. Furthermore, the effect of pipe oscillation on pressure loss in a vertical pipe with horizontal motion was investigated. As the result of the investigation, it was confirmed that the effect was negligible for the prototype model.
