A first set of modules (2, 4, 6, 8) is arranged in a first column (30) and a second set of modules (3, 5, 7, 9) is arranged in a second column (31). A space (32) is defined between the columns, over which space the drilling deck (10) is designed to be positioned.
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.
