Management of Tags and Tag-Related Technical Information in Small and Large Scale Modifications: An Application for a Drilling Rig

Considerable amount of Oil and Gas (O&G) production and process installations operating in the North Sea are getting aged and requiring continuous modifications. Nature of such contractual jobs is relatively short term with demanding deliverables. Hence, the engineering contractors require excellent coordination and seamless communication during all phases of a project. For any contractor/suppl...

Modeling and Experimental Study on Drilling Rig Anti-jamming Valve with Bp Neural Network

Article history: Received: 17.3.2015. Received in revised form: 22.9.2015. Accepted: 24.9.2015. An effective anti-jamming system is significant in improving the working reliability of hydraulic drilling rigs. An anti-jamming valve is a core component of an anti-jamming system. A backpropagation (BP) neural network model was established for an anti-jamming valve by analyzing the structure and wo...
