The main brake of a drilling rig is the mechanical band brake or the hydraulic/ mechanical disk brake system. As the name implies, the primary method of stopping the draw-works drum is by the use of the main brake. It is, therefore, essential. .
In conclusion, Figure 11 shows draw-works brakes’ speed/torque characteristics. 1. Friction brakes may have very high static friction, but with a limitation of dynamic friction. 2. Hydraulic. .
Auxiliary brakes control the descent rate of the traveling block carrying a heavy load. They serve to: 1. Ensure that the load comes down slowly and smoothly. 2. Reduce the wear of. The main brake of a drilling rig is the mechanical band brake or the hydraulic/ mechanical disk brake system. As the name implies, the primary method of stopping the draw-works drum is by the use of the main brake.
[pdf] The drawworks on a drilling system consists of a large winch drum, brakes and a power source. It raises and lowers the drilling line as required, often to support the installation of piping as the borehole deepens.
[pdf] The XLE4 is based on the design of the three existing rigs, but will have several modifications and incorporate enhanced features to improve efficiency, safety and onboard logistics that will make it the largest and most advanced jack-up rig in the world. These include dual pipe handling to maximise uptime and. .
In the North Sea, the Maersk drillship Gallant has drilled to an even greater depth. In August, the company reported that at a total depth of 5,941 metres, it had beaten the record for. .
Maersk Drilling’s chief commercial officer Ana Zambelli says the new drilling technology is the differentiating factor for customers when oil prices are so low. Offshore installation manager Craig Fraser adds: “It’s a demanding industry. Clients want performance. .
The bottom line for Maersk, as it is for other companies, is to drive down costs. Senior commercial advisor Erik Schou has been prominent in the build-up of Maersk Drilling’s activities in.
