Description
1 Description An offshore platform, often referred to as an oil platform or oil rig, is a large structure used to house workers and machinery needed to drill wells in the ocean bed, extract oil and/or natural gas, process the produced fluids, and ship them to shore. Depending on the circumstances, the platform may be attached to the ocean floor, consist of an artificial island, or be floating. When the wells have been drilled, a supporting jacket is installed to support the conductors. A platform is then installed on the jacket to provide a base for process equipment and personnel access. Both the jacket and platform topsides represent large loads, and are typically installed using either a drilling rig or a floating crane barge. A large component of the cost of the installation of small platforms vests in the transportation and installation of the topsides. This cost is constituted of either drilling rig time or the use of a crane barge, as well as transportation to site. The topsides are not necessarily installed directly after completion of the jacket, and having a system available that could facilitate the installation of topsides without cranage would constitute a significant advantage. The present invention is a device / system that allows for the installation of topsides modules without the use of external cranage. The system consists of a static frame that could either be installed immediately after the jacket, or be integrated into the jacket structure. The process equipment to be utilised on the platform is packaged in a standardised module structure, which could be similar or identical to standard ISO shipping containers, but it not necessarily limited to these standard parameters. Modules are installed from a low-cost solution (such as a supply boat), using a winch either temporarily or permanently installed on the platform. The module frame allows for the connection of rigging to facilitate the lifting / lowering of modules.
2 The invention can be better understood by referring to the attached drawings. Figure 1 illustrates the jacket structure being transported to site. The module frame, which forms part of the present invention is rigidly and permanently connected to the jacket in this case, which may or may not always be the case. Figure 2 shows the jacket structure being installed on the well conductors using a drilling rig. With current practice, the drilling rig has to remain on site to install the platform topsides, or a crane barge needs to be present on site. With the new invention, this is no longer required leading to significant cost savings. Figure 3 shows how the modules could be installed from a conventional supply boat. The winch utilised may or may not be temporarily installed on the platform. The module is lifted into position, and secured to the module frame. It would be possible to replace modules at any time using the same working method. Figure 4 illustrates a platform with two modules installed.
