A new strategy for active control in heavy-lift offshore crane operations is suggested, by Correlação do transtorno de compulsão alimentar em pacientes com cirurgias bariátricas introducing a new concept referred to as wave synchronization.Wave synchronization reduces the hydrodynamic forces by minimization of variations in the relative vertical velocity between payload and water using a wave amplitude measurement.Wave synchronization is combined with conventional active heave compensation to obtain accurate control.Experimental results using a scale model Gonadotropin-Releasing Hormone (GnRH) Agonist Implants for Male Dog Fertility Suppression: A Review of Mode of Action, Efficacy, Safety, and Uses of a semi-submerged vessel with a moonpool shows that wave synchronization leads to significant improvements in performance.

Depending on the sea state and payload, the results indicate that the reduction in the standard deviation of the wire tension may be up to 50.
