Methods and apparatuses for active heave compensation, the method, in certain aspects, including the steps of: (a) measuring with a measurement device (44) the heave of a vessel (10) and outputting a heave signal representative thereof; (b) using said heave signal to compensate for said heave by moving a connection device (20) relative to said vessel (10) as a function of said heave signal, whereby movement due to said heave of a load attached to said vessel via the connection device is reduced; said heave signal comprising errors induced by said measurement device (44) whereby accuracy of said compensation is reduced; (c) processing said heave signal so as to reduce said errors and outputting an adjusted heave signal; and (d) using said adjusted heave signal to move said connection device (20) to compensate for said heave.
L'invention concerne des procédés et des appareils pour la compensation active du tangage, le procédé, dans certains aspects, incluant les étapes qui consistent à : (a) mesurer à l'aide d'un dispositif de mesure (44) le tangage d'un vaisseau (10) et à générer une signal de tangage représentatif; (b) utiliser ledit signal de tangage pour compenser ledit tangage en déplaçant un dispositif de connexion (20) par rapport audit vaisseau (10) en fonction dudit signal de tangage, le mouvement résultant dudit tangage d'une charge fixée audit vaisseau via le dispositif de connexion étant réduit; ledit signal de tangage comprenant des erreurs induites par ledit dispositif de mesure (44) ladite précision de ladite compensation étant réduite; (c) le traitement dudit signal de tangage de manière à réduire lesdites erreurs et la génération d'un signal de tangage ajusté; et (d) l'utilisation dudit signal de tangage pour déplacer ledit dispositif de connexion (20) pour compenser ledit tangage.
