Definitions

  • ABSTRACT Device for handling rigid elongated members such as drill string elements by transferring the same from a horizontal storage location to a vertical position where they are assembled to the drill string or vice versa, comprising a carriage with gripping means for taking said elements from their storage position and holding them, rollers fastened to said carriage and cooperating with guiding paths, comprising upper rollers for driving the nearest end of said carriage with respect to said vertical position along a first inclined path terminating with a vertical portion in line with said vertical position, lower rollers for driving the farthest end of said carriage with respect to said vertical position along a generally horizontal path above the storage location and rollers at an intermediate level taking their bearing on a second inclined path with a smaller inclinationas
  • the elongated members may consist, for example of rigid elements from a drill string used in off-shore drilling from a floating installation, e.g., a drilling ship or barge and the following description will refer more particularly to such-an example of use although the scope of the invention is not limited thereto.
  • some handling devices for elongated members consist essentially of articulated arms, comprising means for gripping the elements, for transporting the same from their horizontal storage position to their vertical position of use, i.e., of assembling.
  • These devices sufier from the drawback of being bulky, particularly when used in the vicinity of the working area, and the movements of the handling articulated arms equipping a floating installation tends to change the equilibrium of said installation, this being detrimental to the assembling work, which is then difficult to perform.
  • This end is then hooked to a lifting device which displaces the element from a substantially horizontal position to the desired vertical one.
  • Such a guiding path comprising a first portion for placing the element in a fist position substantially parallel to its storage position and a second portion for placing the element in a second position substantially parallel to the position of use of said element, above the working platform, suffers from the drawback of encumbering the working platform since, if it is desired to hold the elongated element at least at two points thereof during the whole of its handling period, through guiding members, it is necessary that said first and second portions of the guiding path be extended up to the immediate vicinity of the working platform.
  • One of the objects of the present invention is to provide a device for handling elongated elements which avoids the above-mentioned drawbacks and particularly to provide a handling device whereby a cleared working area is obtained so as to make the work easier and to improve the safety conditrons.
  • Another object of this invention is to provide a device of small bulk for handling elements between their storage location and their place of use, which device is easily adaptable to a drilling ship.
  • the invention provides a device for handling an elongated element, whereby it can be transferred from a storage position to a position of use forming with the storage position a substantial angle, said position of use being above a working area.
  • This device is characterized in that it includes in combination at least two guiding members, spaced from each other, such as rollers, carried on transfer means, which may consist of a slope carriage, guiding means formed of at least one guiding path adapted to receive said guiding members, said guiding means comprising a first guiding portion providing for the displacement of said transfer means in a plane substantially parallel to the storage position of the elongated element and a second guiding portion adapted to bring each element to a second position substantially parallel to its position of use, at least one intermediate portion, connected to at least one of said first and second portions, being provided for progressively guiding said transfer means from said first portion to said second portion of said guiding path, said intermediate portion of the guiding path being inclined with respect to the storage position and to the position of use of the elongated element, and being spaced from the working area so as to clear the same.
  • said second portion of the guiding path comprises, above the working area, an inclined part amply clearing said working area, said first guiding portion terminates at one end in the vicinity of said working area and a third portion of the guiding path, comprising an inclined part, and placed above said second portion of the guiding path, at a height which is compatible with a sufficient clearing of the working area, this third portion of the guiding path being adapted to support a third guiding member for'the elongated element, placed in an intermediate position with respect to said two above-mentioned guiding members, when, during its transportation, said element reaches the end of said first guiding portion, thereby providing for the continuous holding of the elongated element by the guiding path during the transfer of said element.
