Lifting and lowering a load on the amina muaddi scarpe trasparenti ocean can be a dangerous task but can be made easy and safe by adopting heave compensation (HC) devices.The design and full-scale experimental results of a 3000-m semi-active heave compensation (AHC) system for a 200-T winch are presented in this paper.First, the design requirements are given and the semi-AHC mechanism is chosen.An integrated cylinder with one passive chamber and two active chambers is designed.Then, the capacities of the passive and active chambers bookers 2022-04 are determined.
The hydraulic and electrical systems and the control strategies are introduced subsequently.Finally, full-scale factory tests at different sinusoidal wave periods and amplitudes show that the semi-AHC system has a displacement compensation efficiency of 92.9% met the design requirements.In-depth power analysis further shows that the active and passive chambers contribute 20.5% and 72.
4% displacement compensation efficiencies, respectively.The efficiency of the passive chamber consists with the 68%-80% passive compensation efficiency from Oceanworks Company and Rexroth Company.
