Title
(EN) HEAVE COMPENSATION SYSTEM
(FR) SYSTÈME DE COMPENSATION DE PILONNEMENT
Abstract
(EN)
A compact and simplified heave compensation system for reducing the effect of waves or wavelike movements on a lifting device. The system can have active and passive heave compensation components. An overload protection to protect lifting equipment can also be implemented. The system enables accurate load and displacement calculations, as well as simplifying the control schemes utilized for lifting devices.
(FR)
L'invention concerne un système compact et simplifié de compensation de pilonnement permettant de réduire l'effet des vagues ou de mouvements similaires à des vagues sur un dispositif de levage. Le système peut comprendre des composants actifs et passifs de compensation de pilonnement. Une protection contre les surcharges pour protéger un équipement de levage peut également être mise en œuvre. Le système permet des calculs de charge et de déplacement précis, et de simplifier les schémas de commande utilisés pour les dispositifs de levage.
