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...

Recently, we have seen falling oil prices combined with sticky costs at a high level in the petroleum industry. This cause cost cuts and project postponements, thus challenging reserve replacement of oil companies and security of supply for consumers. Costs are particularly high for drilling. High rig rates are obviously important. In new contracts for high-spec semi rigs on the Norwegian Conti...

This paper presents an approach to Cartesian controlled heavy machines. The system under investigation is a drill rig equipped with two drilling booms each actuated by eight hydraulic drives. To improve accuracy and efficiency in both possible operation modes, drilling and bolting, a Cartesian control system has been implemented, which takes advantage of using different subsets of the redundant...

We propose a scalable state estimator with wave filter for surface vessels. The filter is shown to be either globally or locally exponentially stable depending on configuration. Performance is illustrated using actual data from a full scale semi-submersible drilling rig.

Drilling operations are increasingly becoming a manufacturing process where repeatability, versatility, and speed matter the most for an operator or future space missions. Nonetheless, ongoing energy transition efforts will undoubtedly shape objectives priorities of drilling operators into new markets with unexplored technical challenges. Versatility, mobility, automated systems play crucial ro...
