Integrating sensors for robots operating on offshore oil and gas platforms

This thesis presents a solution to integrate sensors and instruments on a robot to be used instead of operators on unmanned oil and gas offshore platforms. Operators have various tasks from inspection to maintenance in the platforms. Because of high costs of having operators in offshore platforms, there has been always an ambitious to design a fully unmanned automated platform to decrease the costs and increase human safety in oil and gas industry. These days Robotics is quite mature to be utilized in different industries. There are few manufacturers that produce robots in order that robots perform some activities in industrial environment. But the Robot usage in offshore platforms has higher risks and they have not been used before as a rigid solution, because of inaccessibility to platforms at all conditions (such as bad weather). In this thesis, I have collected the operator tasks which are possible to be done by robots, provided main requirements to use the robots in oil and gas offshore platforms and found the sensors and instruments to be suitable to mount on the robot to measure, collect and analyze required data. Finally, the proper way for data processing and analysis was done in MATLAB Simulink to present the result of measurements and data collection. The topic of this thesis was inspired from oil and gas offshore industry and robots are going to be used in one of the largest oil and gas offshore projects in North Sea (Yggdrasil) which will be started to operate from 2027. This EPC project (Engineering Procurement Construction) has been started from 2021 and currently is ongoing in detail engineering. The information regarding operators’ tasks and required specifications for sensors and instruments were provided based on this project requirements. The report of this thesis can be used in future for the sensors and their integration on robots. It was not possible to test or prototype on existing robots within master thesis schedule because of different schedule of the master thesis and this oil and gas project. Only simulation was carried on showing the results of this thesis

Signal Processing Using Non-invasive Physiological Sensors

Non-invasive biomedical sensors for monitoring physiological parameters from the human body for potential future therapies and healthcare solutions. Today, a critical factor in providing a cost-effective healthcare system is improving patients' quality of life and mobility, which can be achieved by developing non-invasive sensor systems, which can then be deployed in point of care, used at home or integrated into wearable devices for long-term data collection. Another factor that plays an integral part in a cost-effective healthcare system is the signal processing of the data recorded with non-invasive biomedical sensors. In this book, we aimed to attract researchers who are interested in the application of signal processing methods to different biomedical signals, such as an electroencephalogram (EEG), electromyogram (EMG), functional near-infrared spectroscopy (fNIRS), electrocardiogram (ECG), galvanic skin response, pulse oximetry, photoplethysmogram (PPG), etc. We encouraged new signal processing methods or the use of existing signal processing methods for its novel application in physiological signals to help healthcare providers make better decisions

Optimising mobile laser scanning for underground mines

Despite several technological advancements, underground mines are still largely relied on visual inspections or discretely placed direct-contact measurement sensors for routine monitoring. Such approaches are manual and often yield inconclusive, unreliable and unscalable results besides exposing mine personnel to field hazards. Mobile laser scanning (MLS) promises an automated approach that can generate comprehensive information by accurately capturing large-scale 3D data. Currently, the application of MLS has relatively remained limited in mining due to challenges in the post-registration of scans and the unavailability of suitable processing algorithms to provide a fully automated mapping solution. Additionally, constraints such as the absence of a spatial positioning network and the deficiency of distinguishable features in underground mining spaces pose challenges in mobile mapping. This thesis aims to address these challenges in mine inspections by optimising different aspects of MLS: (1) collection of large-scale registered point cloud scans of underground environments, (2) geological mapping of structural discontinuities, and (3) inspection of structural support features. Firstly, a spatial positioning network was designed using novel three-dimensional unique identifiers (3DUID) tags and a 3D registration workflow (3DReG), to accurately obtain georeferenced and coregistered point cloud scans, enabling multi-temporal mapping. Secondly, two fully automated methods were developed for mapping structural discontinuities from point cloud scans – clustering on local point descriptors (CLPD) and amplitude and phase decomposition (APD). These methods were tested on both surface and underground rock mass for discontinuity characterisation and kinematic analysis of the failure types. The developed algorithms significantly outperformed existing approaches, including the conventional method of compass and tape measurements. Finally, different machine learning approaches were used to automate the recognition of structural support features, i.e. roof bolts from point clouds, in a computationally efficient manner. Roof bolts being mapped from a scanned point cloud provided an insight into their installation pattern, which underpinned the applicability of laser scanning to inspect roof supports rapidly. Overall, the outcomes of this study lead to reduced human involvement in field assessments of underground mines using MLS, demonstrating its potential for routine multi-temporal monitoring

Biologically-inspired radar sensing

The natural world has an unquantifiable complexity and natural life exhibits remarkable techniques for responding to and interacting with the natural world. This thesis aims to find new approaches to radar systems by exploring the paradigm of biologically-inspired design to find effective ways of using the flexibility of modern radar systems. In particular, this thesis takes inspiration from the astonishing feats of human echolocators and the complex cognitive processes that underpin the human experience. Interdisciplinary research into human echolocator tongue clicks is presented before two biologically-inspired radar techniques are proposed, developed, and analyzed using simulations and experiments. The first radar technique uses the frequency-diversity of a radar system to localize targets in angle, and the second technique uses the degrees-of-freedom accessible to a mobile robotic platform to implement a cognitive radar architecture for obstacle avoidance and navigation

EG-ICE 2021 Workshop on Intelligent Computing in Engineering

The 28th EG-ICE International Workshop 2021 brings together international experts working at the interface between advanced computing and modern engineering challenges. Many engineering tasks require open-world resolutions to support multi-actor collaboration, coping with approximate models, providing effective engineer-computer interaction, search in multi-dimensional solution spaces, accommodating uncertainty, including specialist domain knowledge, performing sensor-data interpretation and dealing with incomplete knowledge. While results from computer science provide much initial support for resolution, adaptation is unavoidable and most importantly, feedback from addressing engineering challenges drives fundamental computer-science research. Competence and knowledge transfer goes both ways
