To investigate the heave compensation capability of a wave compensation hoisting device, a simulation test bench for the hoisting device was built by using an ordinary hydraulic cylinder and an ordinary accumulator to replace dedicated compensation cylinders and accumulator, and a simulation model was then established based on AMESim. Experiments and simulations were performed to compare the compensation rate and energy consumption of the hoisting device under passive, semi-active and active compensation modes. In the passive compensation mode, the simulated compensation rate was 14.64% and the experimental value was 13.51%; in the semi-active compensation mode, the simulated compensation rate was 91.01% and the experimental value was 89.80%; the simulated compensation rate reaches 94.44% under the active compensation mode. Both simulation and experimental data prove that this alternative scheme can deliver high compensation rate with low energy consumption. It is regarded as a low-cost and efficient solution for testing wave compensation hoisting device, providing a verification platform for subsequent design and optimization of wave compensation hoisting device.
