Design and implementation of model test installation of heave compensation system of deepsea mining

Abstract

In order to validate the simulation model and develop heave compensation control strategy, heave compensation model tests were performed. The model test installation includes the mining ship motion simulator, the heave compensation system, the lifting pipe simulator, the buffer simulator and the water pool. The tests of mining ship motion simulator show that it is able to perform under the predetermined attitude path smoothly and can meet the requirements of the mining ship motions. The heave compensation effect is more than 60% under random wave and the goal is set to be 50%. The model test results indicate that this heave compensation system is effective and feasible.
