Definitions

  • Moise, II et al. states that preferably, the total bottom surface area of the pads is preferably at least 30% of the surface area of the deck of the lift boat. Moreover, Moise describes that the total bottom surface area of the pad is large enough such that, when the boat is loaded and jacked up, the pads exert less than 7 psi on the sea floor. Moise further describes propelling the boat using two rear propellers and rudders.
  • FIG. 6 is a side view of the workover rig disposed on the sub-base structure of the present invention.
  • the two front azimuthing thrusters are preferably mounted to the bow of the Elevating Support Vessel 100, along the horizontal, at a generally front-most location.
  • the crane 112 may also be rotated 360° about the crane-support column 165 while under full load.
  • the crane 112 may also be skidded along the tracks 159 while under load. Accordingly, the crane 112 may transport load or erect load in a self-contained manner, without need for any additional support vessels.
  • the crane 112 has the additional benefit of allowing for the storage of equipment and things beneath the crane support 109. Because of the high clearance of the crane-support platform 162, the storage of equipment and things will not obstruct the movement of the crane 112. Additional uses of the crane 112 are discussed below.
  • the crane 112 is used to retract the anchor, hi this embodiment, once the first anchor is released from the sea/ocean floor the azimuthing thrusters will be used to correct for the deviation that the Elevating Support Vessel 100 undergoes from the set point. The azimuthing thrusters continue to correct for any deviation from the set point as the additional anchor(s) are retracted. Alternatively, after the first anchor is released from the sea/ocean floor, the azimuthing thrusters serve to hold tension against the other anchors such that the vessel holds station.

Abstract

L'invention concerne un navire qui constitue une amélioration par rapport à des plateformes auto-élévatrices et à des bateaux de levage de l'état antérieur de la technique. Le navire présente au moins trois propulseurs et est automoteur. Le navire présente en outre un support de grue creux et surélevé sur lequel une grue peut être montée. Le support de grue est fixé à des rails, qui permettent à la grue de coulisser le long du pont du navire. La caractéristique creuse et surélevée du support de grue permet le stockage d'un équipement et de choses sous le support de grue sans entraver le déplacement de la grue le long des rails. Eventuellement, le navire comprend également une structure d'appui fixée de manière amovible sur le tableau du navire; une structure de base fixée de manière amovible à la structure d'appui; et un appareil de reconditionnement fixé de manière amovible à la structure de base. L'invention concerne également des procédés d'utilisation de la grue et de fixation de la structure d'appui, de la structure de base et de l'appareil de reconditionnement sur le tableau du navire.
