Like reference signs refer to like elements throughout.
Figure 1 show an example of an inventive stressed-skin drilling derrick 1mounted on a deck 2, wherein the drilling derrick 1 is a welded load-bearingunitary construction. The drilling derrick 1 comprises a plurality of stiffenedpanels 3 which are respectively attached to the opposing edges 4 of adjacentexternal stiffened panels or adjacent structural sections which may constitutepart of the drilling derrick 1. The drilling derrick 1 may either fully or partlycomprise of stiffened panels 3.
Further, the drilling derrick 1 may vary in size over the height of the drillingderrick 1, from a bottom part 9 of the drilling derrick 1 supported on the deck2 to a top part 10 of the drilling derrick 1. The drilling derrick 1 is arranged toaccommodate any suitable equipments for drilling operations, such as forexample a drill pipe device (not shown), pipe sections (not shown) and a piperacking structure (not shown). The drilling derrick 1 comprises closableopenings (not shown). The drilling derrick 1 may be adapted to provide a relatively large working, handling and storage area inside the drilling derrick1.
The stressed-skin construction technique which is used in the inventivedrilling derrick 1 supports structural loads by using the exterior or shell of thedrilling derrick 1, as opposed to using a conventional drilling derrick having aload-bearing frame or truss which is then covered with a non-load-bearingskin or coachwork. The stiffened panels 3 constitute the exterior or shell ofthe drilling derrick 1.
Fig. 2 schematically shows a pictorial representation of a stiffened panel 3according to the invention. The external stiffened panel 3 comprises an outerplating skin 7 reinforced by inner vertical stiffeners 5 and inner horizontal ribmembers 6 in a substantially rectangular pattern 8. The inner verticalstiffeners 5 and inner horizontal rib members 6 may be mounted andconnected to the outer plating skin 7 by any conventional method such aswelding, screwing, riveting or bolting. Preferably, the inner vertical stiffeners 5and inner horizontal rib members 6 are mounted and connected to the outerplating skin 7 and to each other by welding. Normally, when the inventivedrilling derrick 1 is mounted as a unitary construction on the deck 2 of anoffshore platform, the inner horizontal rib members 6 are horizontal and theinner vertical stiffners 5 are substantially vertical.
The inner vertical stiffeners 5 and the inner horizontal rib members 6 may beany type of structural member such as for example HP-bulb profile, L-profile,Flat bar profile, Trapetzoid-profile, Box-profile, U-profile or T-profile. Theinner vertical stiffeners 5 and the inner horizontal rib members 6 in a stiffenedpanel 3 may be of different types structural members. The inner verticalstiffeners 5 and the inner horizontal rib members 6 in a stiffened panel 3 maybe the same type of structural member.
The stiffened panels 3 which are used in the stressed-skin structure of thedrilling derrick provide a type of construction in which the outer plating skins 7and the inner vertical stiffeners 5 and inner horizontal rib members 6 interact,thus contributing to the overall strength of the drilling derrick.
The stiffened panels 3 can be mounted and connected to each other by anyconventional method such as for example welding, screwing, riveting orbolting. Preferably, the stiffened panels 3 are mounted and connected to each other by welding.
The stiffened panel 3 may comprise of any suitable number of inner verticalstiffeners 5. The stiffened panel 3 may comprise of any suitable number ofinner horizontal rib members 6. Normally, the stiffened panel comprise of more inner vertical stiffeners 5 than inner horizontal rib members 6.
The inner vertical stiffeners 5 and the horizontal rib members 6 are arrangedto be mounted and connected to each other at inner crossing sections 11.The inner vertical stiffeners 5 and inner horizontal rib members 6 arearranged in the rectangular pattern 8 having inner crossing sections 11,where either the inner vertical stiffeners 5 or the horizontal rib members 6may be mounted and connected to each other and arranged through eachother at the inner crossing sections 11. The connection of the inner verticalstiffeners 5 and inner horizontal rib members 6 at the inner crossing sections11 may be done by using any conventional method such as for examplewelding, screwing, riveting or bolting. Preferably, the inner vertical stiffeners 5and the horizontal rib members 6 are mounted and connected to each otherby welding.
The stiffened panel 3 comprising the outer plating skin 7, the inner verticalstiffeners 5 and the inner horizontal rib members 6 can be made of anysuitable material. The stiffened panels 3 can be arranged to be connected to each other forming any suitable geometrical form, for example such that wind force influence on the drilling derrick can be reduced. Thus, the inventivesolution can simultaneously provide both a weather protected working,handling and storage area and a non-bulky and light-weight drilling derrickwhich also can reduce the wind force influence on the drilling derrick.
Figure 3 shows an example of a drilling derrick 31 having an enlarged lowerpart 32, such that a larger enclosed working, handling and storage areaabove the deck 2 can be provided. The drilling derrick 31 comprisesextending stiffened panels 33 at a lower part 32 of the drilling derrick 31,such that a larger enclosed area above the deck 2 is provided. The lower part32 of the drilling derrick 31 has a cross section surface which is substantiallylarger than the largest cross section surface of the upper part 34 of thedrilling derrick 31. The lower part 32 of the drilling derrick 31 has a crosssection surface which is at least 50 percent larger than the largest crosssection surface of the upper part 34 of the drilling derrick 31. This drillingderrick 31 having an enlarged lower part 32 may provide a larger enclosedarea above the deck 2 than if it had a continuous variation in size from thetop part to the bottom part of the drilling derrick.
