Abstract
A drilling rig device (1) situated on the seabed (11), where the drilling rig (1) is sealingly enclosed against the surroundings, wherein the pipe (23) coupling unit (24) of the drilling rig (1) is closed, provided with seals (25) against the pipe (23) and connected to a liquid collector and separator (33).
Description
- This invention regards a device for separating material from a coupling unit in a drilling rig situated on the seabed. More particularly, it regards a drilling rig situated on the seabed, where the drilling rig is sealingly enclosed against the surroundings. The pipe coupling unit in the drilling rig is closed, provided with seals against the pipe and connected to a liquid collector and separator.
- It is common knowledge that oil and gas deposits in the earth's crust are recovered by drilling holes down to the deposits, to allow oil and gas deposits to be drained to the surface.
- The equipment used to drill holes in the earth's crust primarily comprises a drilling derrick formed as a trussed steel structure. In the drilling derrick there is a wireline based drawworks for hoisting and deploying drill pipes. A great deal of auxiliary equipment is also used to handle drill pipes and to set casing in the borehole.
- Floating or fixed platforms provided with the required drilling equipment are utilized to recover oil and gas deposits from great depths. These types of platforms are large and expensive structures, as the drilling equipment is large and heavy. In addition to the actual drilling equipment, marine risers must also be used to circulate drilling mud between the platform and the seabed during the drilling operation. Floating platforms also require heave compensation to accommodate wave motion against the platform relative to the seabed.
- As an alternative to drilling from floating drilling platforms, the drilling rig may be arranged directly on the seabed, obviating the need for large and expensive platforms.
- Today, the oil industry possesses a great deal of advanced equipment developed for remote-controlled subsea operations. This is technology that is available and may be used during a remote-controlled drilling operation where the drilling equipment is situated directly on the seabed.
- Furthermore, it is necessary to meet the relatively strict requirements set by the authorities in connection with environmental pollution and the target of zero discharge to the environment.
- Prior art does not provide a solution to these problems in connection with drilling rigs situated on the seabed.
- The object of the invention is to remedy or reduce at least one of the drawbacks of prior art.
- The object is achieved in accordance with the invention, through the features given in the description below and in the following claims.
- A drilling rig in accordance with the invention is situated on the seabed, the drilling rig being sealingly enclosed against the surroundings, and it is characterized in that the pipe coupling unit of the drilling rig is closed, provided with seals against the pipe and connected to a liquid collector and separator.
- The separator is connected to a circulation system arranged to circulate liquid through the coupling unit, the circulation system comprising a pump and conduits in addition to the separator.
- The inlet of the circulation system communicates with one of the upper or lower part of the drilling rig, while the outlet of the circulation system communicates with the other of the upper or lower part of the drilling rig.
- Preferably, the hydrostatic pressure inside the drilling rig is lower than that outside the drilling rig, whereby liquid in the drilling rig is prevented from flowing out to the surroundings of the drilling rig.
- The separator is connected to e.g. a container for separated material, the container, when filled, may be replaced with a new container and brought up to the surface for further processing of the separated material. The drilling rig may comprise several containers for separated material.
- Preferably containers going into and out of the drilling rig are passed through lock arrangements.
- A device according to the invention provides a solution for handling e.g. drilling fluid flowing out during disconnection of pipes, the liquid in the coupling unit being circulated through the separator.
