Definitions
- the present invention regards a modular lightweight drilling rig in accordance with the preamble of the appended Claim 1.
- a drilling rig is put up by a structure being assembled from basics directly on a platform, i.e. on the platform deck.
- This structure comprises a substructure containing service functions such as pumps, compressors and other equipment, and defines a drilling deck on top of the substructure.
- the actual derrick is arranged on this drilling deck.
- Such construction is time consuming, and must be closely co-ordinated in order to avoid delays, e.g. due to components not being ready when they are due to be assembled.
- Another much used method is to build the entire structure up separately from the platform and then place it on the platform, for instance by lowering the platform so that the structure may be guided into place e.g. by a barge.
- This method requires the use of expensive high capacity equipment in order to guide the structure into place. It also entails great risks.
- each module has a weight that is less than the lifting capacity of a moderately sized crane. It is desirable for each module to weigh less than 25 tonnes. Furthermore there is a need for a modular rig structure that may readily be assembled and has an overall weight that is small in comparison with conventional rig structures.
- the present invention aims to provide a lightweight modular rig structure that may be assembled in a simple manner and has a high degree of applicability. It is also an object of the present invention to provide a structure consisting of a limited number of modules, in which each module has a limited weight. It is also an object of the invention that each module be easy to transport. It is a further object of the invention to provide a structure that may be assembled in a very simple and effective manner, and for which the requirement for assembly detail and supports is minimised.
- FIG. 1 shows a modular lightweight rig structure 1 according to the present invention.
- the structure generally consists of the following modules: A first frame module 2 and a second frame module 3, a first lower module assembly 4 and a second lower module assembly 5, a first upper module assembly 6 and a second upper module assembly 7, a first piping deck 8 and a second piping deck 9, a drilling deck 10 and a derrick 11.
- the frame modules 2 and 3 are designed to be placed on longitudinal sliding rails 12 and 13 that are fixed to the platform deck 15.
- the BOP 14 deck also acts as a spacer for frame modules 2 and 3, and is connected to these in a manner so as to fix the frame modules relative to each other.
- the frame modules each consist of a base frame 2a, 3a respectively and two side frames 2b, 2c and 3b, 3c respectively.
- the first and second lower module assembly 4 and 5 consist of a plurality of single modules 4a-4d and 5a-5d respectively, with the case as shown comprising four single modules in each module assembly.
- the single modules 4a-4d and 5a-5d respectively are placed side by side, against each other.
- the module assembly 4 is designed to be placed inside frame module 2
- the module assembly 5 is designed to be placed inside frame module 3, on top of the base frames 2a and 3a respectively and between the side frames 2b, 2c and 3b, 3c respectively.

Abstract
Description
- The present invention regards a modular lightweight drilling rig in accordance with the preamble of the appended Claim 1.
- Traditionally, a drilling rig is put up by a structure being assembled from basics directly on a platform, i.e. on the platform deck. This structure comprises a substructure containing service functions such as pumps, compressors and other equipment, and defines a drilling deck on top of the substructure. The actual derrick is arranged on this drilling deck. Such construction is time consuming, and must be closely co-ordinated in order to avoid delays, e.g. due to components not being ready when they are due to be assembled.
- Another much used method is to build the entire structure up separately from the platform and then place it on the platform, for instance by lowering the platform so that the structure may be guided into place e.g. by a barge. This method requires the use of expensive high capacity equipment in order to guide the structure into place. It also entails great risks.
- Attempts have been made to construct such a structure by use of modules, however none of the attempts so far have been particularly successful. Examples in this respect are shown in:
- DE 1009575, which shows a land based drilling rig assembled by modules. However, this rig is designed to be used on land, and will not be suitable offshore.
- SU 1709059, which shows a rig consisting of a large number of rectangular modules. The modules are placed two and two in each level. The modules of adjoining storeys are placed in right angle to each other, in the same way as a match tower. This means that the access to the interior of the tower is very limited.
- SU 1836534, which shows a modular rig similar to SU 1709059, and with the same disadvantages.
- Thus there is a great need for an improved modular rig structure in which each module has a weight that is less than the lifting capacity of a moderately sized crane. It is desirable for each module to weigh less than 25 tonnes. Furthermore there is a need for a modular rig structure that may readily be assembled and has an overall weight that is small in comparison with conventional rig structures.
- The present invention aims to provide a lightweight modular rig structure that may be assembled in a simple manner and has a high degree of applicability. It is also an object of the present invention to provide a structure consisting of a limited number of modules, in which each module has a limited weight. It is also an object of the invention that each module be easy to transport. It is a further object of the invention to provide a structure that may be assembled in a very simple and effective manner, and for which the requirement for assembly detail and supports is minimised.
- An embodiment of the present invention will be explained in greater detail in the following, with reference to the accompanying drawings, in which:
- Figure 1 shows an exploded view of a rig structure in accordance with the present invention;
- Figure 2 shows a perspective drawing of a rig structure in accordance with the present invention;

Furthermore, it is possible to see the firstupper module assembly 6, which is positioned on top of theframe module 2. Themodule assembly 6 is shown as a trussed construction in order to indicate the fact that it is load-bearing.
