Definitions

  • the present invention concerns a drilling deck/moonpool door for a vessel performing drilling or subsea operations, where the drilling deck/moonpool door may be opened to give access to the "moonpool"-opening or the sea surface when lowering equipment in connection with drilling tasks.
  • the solution according to the present invention is equip ⁇ ping the drilling deck/moonpool hatch with a slidable middle part of the deck where this part is guided by hydra ⁇ ulically, mechanically or pneumatically operated carrying arms, said arms ranging an area which at least corresponds in height to the thickness of the middle section of the deck so that this part of the deck, when operated by the arms, is elevated to the extent that it clears the sur ⁇ rounding deck surface and consequently may be pushed or pressed away from its resting position in the middle area of the deck.
  • FIG. 1 shows a drilling vessel with a middle deck area equipped with an elevatable section which may be moved from its resting position i the vessel's deck;
  • Fig. 2 shows a bird's eye view of the section of the dril ⁇ ling deck/moonpool hatch according to the present invention where the middle section is in the process of being re ⁇ moved;
  • Fig. 3 shows a further bird's cyc view of the drilling deck/moonpool hatch according to the present invention as it appears in an assembled form
  • Fig. 4 a-e show the opening/moving sequence of the drilling deck/moonpool hatch according to the present invention
  • Fig. 5 a-c show in cross section the composition of the support/elevating devices for the drilling deck/moonpool hatch according to the invention as well as sequential elevation and removal of the drilling deck/moonpool hatch;
  • Fig. 6 shows in a bird's view the removal of the drilling deck/moonpool hatch according to the invention
  • Fig. 7 and 8 show designs of the drilling deck/moonpool hatch according to the invention arranged in conjunction with other deck structures on the drilling vessel.
  • figs. 1 and 2 there are shown that the movable parts 1,2 of the drilling deck/moonpool hatch run along rails 3 in the lengthwise direction of the vessel 4. This is because the weight of the drilling deck/moonpool hatch's movable parts normally will be so heavy that it will require as ⁇ sisting devices to transport this or parts thereof.
  • Ad- ditionally fig. 1 shows how the drilling deck/moonpool hatch according to the present invention may be located/mounted in a larger connection among the other drilling devices and drilling equipment on the vessel.
  • the drilling deck/moonpool hatch itself comprises several cooperating and movable parts.
  • the parts 1,2 of the drilling deck/moonpool hatch according to the invention and which may be moved translationarily with re ⁇ spect to each other and with respect to the hull and deck of the vessel 4, are sectioned into two parts 1,2 which interlock into each other, where one part 2 around its edges, except for one, is surrounded by the other part 1.
  • part 1 In its turn part 1 may also be displaced translationarily along the rails 3 on the deck of the vessel.
  • the parts 1,2 may also be present as one monolithic unit, in which case this one part may be moved translationarily only supported by the bracing arms 11,11'.
  • the dril ⁇ ling deck/moonpool hatch comprises flaps 6, 6', 7.7', 8, 8' lying on each side of the central parts 1,2 of the drilling deck/moonpool hatch.
  • These flaps 6,6',7,7'8,8' are divided into categories, where the peripheral flaps 6, 6 ',7, 7' are carried by the central part 1 of the drilling deck/moonpool hatch via e.g. a groove 9,9' running along the longitudinal edges of the drilling deck/moonpool hatch.
  • flaps 6, 6 ',7, 7' may, in the embodiment shown in the figures, be freely lifted and do not have as their task to carry the construction of the drilling deck/moonpool hatch.
  • the middle flaps 8,8' are, however, carried by bracing devices which may be pneumatically, hydraulically or mechanically guided.
  • Fig. 4a shows the drilling deck in a closed position.
  • Fig. 4b shows the corner flaps 6, 6 ',7, 7' raised to an angle of 90° with respect to the main deck/upper deck.
  • Fig. 4c shows, the raising of the drilling deck (usually 80 cm corresponding to the thickness of the main deck).
  • the inner part 2 of the removable drilling deck is moved away from the main part 1 of the drilling deck (usually 3,5 m corresponding to the half length of the drilling deck).
  • Fig. 4d shows the removal of drilling deck 1 via the rails 3 (usually 7 m corresponding to the full length of the drilling deck).
  • Fig. 4e shows the further lifting of the middle flaps 8,8' to an upright position in 90° with re ⁇ spect to the main deck.
  • the peripheral and non-carrying flaps 6, 6 ',7, 7' are raised to an upright position as shown in fig. 4b.
  • the groove 9 in the carrying part 1 of the elevatable drilling de- ck/moonpool hatch, and in which the non-carrying flaps rest may be designed so that the edges of the flaps 6.6',- 7,7' have enough clearage for them to be placed in an upright position without hitting the upper edge of the groove 9.
  • the raising of the non-carrying flaps 6, 6 '7,7' may be done in a conventional manner.
  • the carrying mechanical, pneumatic or hydraulic devices are activated for elevating the middle section 1,2 of the drilling deck/moonpool hatch via the middle flaps 8,8' of the drilling deck/moonpool hatch so that it clears the main deck of the vessel (see fig. 4c).
  • the sliding coupling of the middle flaps 8,8' to the middle section 2 of the dril ⁇ ling deck/moonpool hatch may be ensured by a cooperating groove (tongue and groove) in the flaps and the middle 5 section.
  • this one part 2 of the middle section of the drilling deck/moonpool hatch may be removed, as shown in fig. 4c. -U
  • this part 1 of the middle section may be pulled away via transport on the rails 3.
  • the rails may also be equipped with transporting 15 trolleys, rollers or bearings which ease the movement of the middle section 1 of the drilling deck/moonpool hatch.
  • the groove 9 in the middle section 2 may also be equipped with sliding bearings at the transition area to the carrying middle flaps 8.8' or vice versa.
  • the middle flaps 8,8' When the carrying middle section of the drilling deck has been removed, the middle flaps 8,8' may be moved from their intermediary position (shown in fig. 4d and 5b) to their upright position (shown in fig. 4e and 5c).
  • FIG. 5a-c An embodiment of the carrying/movable parts of the moving mechanism for the drilling deck/moonpool hatch according to the present invention is shown in fig. 5a-c. In fig. 5a-c it is shown a vertical section through a drilling deck/
  • this impingement point is shown as a coupling between the impingement elements 12,12' and a protruding plate 13,13' being located between the upper and lower external surface of the drilling deck/moonpool hatch 1.
  • the location of these protruding plates (elevating plates) is such that the extension of the hydraulic cy ⁇ linders 11,11' via the impingement bodies 12,12' will elevate the drilling deck/moonpool hatch 1,2 up to the level of the guiding rails 3 on the main deck of the vessel so that the drilling deck/moonpool hatch clears this main deck in its upper elevated position.
  • Fig. 5a shows the situation with a closed drilling deck/moonpool hatch.
  • An advantageous and preferred feature in the design of the carrying flaps 8,8' is to equip them with a hinged part 14,14' in an area at the impingement bodies 12,12' which may flip the distal part of the flaps 8,8* over so that they lie at an angle with respect to the surface of the flaps (shown in fig. 5c).

Abstract

Ecoutille soulevable de pont de forage/de moonpool destinée à un navire de forage, qui donne plus d'espace sur le pont de forage et facilite le travail associé aux opérations de forage. L'invention concerne une écoutille de pont de forage/de moonpool destinée à un navire de forage (4), qui comprend, au niveau du pont, une partie médiane (1, 2) coulissante, actionnée par des bras de support hydrauliques, mécaniques ou pneumatiques (11, 11'). Les bras travaillent au-dessus d'une zone correspondant, en hauteur, au moins à l'épaisseur de la partie médiane du pont (2), de façon à soulever cette partie, quand elle est actionnée par les bras, et à libérer la surface de pont environnante. La partie médiane (2) est ainsi éloignée de sa position de repos dans la partie médiane du pont, au niveau de laquelle l'écoutille de pont de forage/de moonpool repose sur la construction située à l'extrémité des rails (3) disposés sur le pont du navire.
