Definitions

  • a winch system for transferring loads between a mother vessel and a daughter vessel and more particularly, a multi-body motion compensation system that, prior to a payload being attached to a winch hook, compensates for the relative motions between the two vessels.
  • Oil platform supply vessels transport cargo and equipment to and from off-shore oil platforms and they serve an important function in the supply pipeline for those that work in the shipping and oil platform industries.
  • a crane can be located on the platform and a crane operator manually operates the crane in concert with deck crews that can be located on both the platform and on the supply vessel.
  • the crane operator may communicate with the deck crews by using telecommunication devices so as to aid in the safe and efficient transfer of payloads between the platform and the supply vessel.
  • the crane operator controls a winch drum which reels in and out a lifting hook that is in turn connected to the winch cable.
  • the deck crew on the supply vessel in turn connects the hook to the payload.
  • the distance between the hook and the deck of the supply vessel changes as the sea heaves, pitches and rolls, thus creating a significant challenge for the crane operator to maintain the lifting hook at a steady position.
  • This also creates a challenge for the deck crew on the supply vessel to maintain control of the lifting lines and the lifting hook prior to it being connected to the payload.
  • a payload is only transferred to and from a supply vessel when the sea state is relatively calm.
  • the calm seas allow minimal relative motion between the lifting hook and the deck of the supply vessel, and this decreased motion allows the deck crews to safely handle the lifting lines and the associated lifting hook.
  • the crane operator often located on the platform, continuously monitors the location of the supply vessel as the lifting hook transfers goods to and from the supply vessel. As long as the sea state remains relatively calm, the crane operator generally can safely maneuver the lifting hook and cargo.
  • Transferring cargo from a supply vessel to another moving vessel likewise can be challenging under heavy seas.
  • the supply vessel is a moving body and the ship is a moving body, thus creating two independent moving bodies.
  • transferring cargo between two moving bodies becomes increasingly difficult, particularly as the sea state increases. This is because the relative motion between the lifting hook and the deck crew increases. Under such conditions the safety challenges increase and often conditions deteriorate to the point where cargo may not be transferred until calmer conditions return.

Abstract

L'invention porte sur un système de compensation de mouvement, lequel système emploie un treuil à moteur, au moins un capteur, et un système de commande, qui sont utilisés pour déplacer une charge utile, par exemple à partir d'un navire avitailleur jusqu'à une plate-forme d'une plate-forme pétrolière. Avant la liaison d'un crochet de levage à une charge utile, le système de compensation règle automatiquement le positionnement du crochet par rapport au pont du navire avitailleur, ce qui, pendant des conditions météorologiques inclémentes en mer, rend plus facile pour des travailleurs sur le pont l'amarrage du crochet de levage au chargement.
