The oil and gas industry in Libya has suffered a number of health and safety accidents including environmental disasters due to the nature of the work involved and the hazardous materials it handles in all facets of exploration and production. Such issues have hitherto not received due attention by the Libyan Authorities. The fact that strict HSE assessment standards are neither well-defined nor established in Libya is not helpful. Furthermore, oil and gas industry in new free Libya has suffered immensely during the 2011 Arab Spring and its rebuilding poses a number of critical HSE challenges. The purpose of the research is to develop and validate a HSE Performance Review Methodology for Libyan oil and gas industry based on clearly defined and measurable aspects for assessment. The thesis starts by performing a comprehensive literature review on all aspects of HSE including universal standards. The review indicates that there is a gap in respect of semi-qualitative methods for assessing HSE performance commensurate with other disciplines. The thesis then identifies four key research problems in the context of Libyan oil and gas industries. Based on these problems, an empirical research was conducted and included three distinct Stages. Stage 1 consisted of a pilot study based on an interview questionnaire with 15 experienced HSE professionals working in oil and gas companies in Libya to help identify key issues pertaining to HSE assessment. Data analysis results for Stage 2 have been used to derive a list of 12 main groups of HSE questions which have then been tested on 84 HSE professionals working in Libya stemming from 35 medium and large oil and gas companies. Modal distribution analyses have been performed to scope down the number of HSE performance factors, which would then be used in Stage 3 of the empirical research. This consisted of issuing the same 84 interviewees with a questionnaire requesting their assessment of how Critical, Important and Less Important were the 60 factors identified. Central Tendency, Variation Ratios and Indices of Diversity were used to successfully analyse the data. With the QAA Subject Review in mind as a potential model for the sought methodology, and a mapping of the four research problems with data analysis results from Stages 1, 2 and 3; six HSE Performance Review Aspects emerged: Prevention, Surveillance, Response, Achievements, Resource and HSE Management and Enhancement – judged and graded using a 1 to 4 scale. The HSE Performance Review methodology has been validated by direct application to five comprehensive studies starting from the self-assessment document written by the companies, an extensive review visit by peer-assessors and a final report showing grades, benchmarks and shortcomings. Lessons learned from the validation exercise have been used to revise the definition of the six Aspects and used to propose an appropriate implementation plan in Libya. The results of the validation exercise are very encouraging and readily confirm that the methodology can be applied to other industry sectors.

Next Generation Networks (NGNs) aim to provide a unified network infrastructure to offer multimedia data and telecommunication services through IP convergence. NGNs utilize multiple broadband, QoS-enabled transport technologies, creating a converged packet-switched network infrastructure, where service-related functions are separated from the transport functions. This requires significant changes in the way how networks are managed to handle the complexity and heterogeneity of NGNs. This thesis proposes a Service Oriented Architecture (SOA) based management framework that integrates heterogeneous management systems in a loose coupling manner. The key benefit of the proposed management architecture is the reduction of the complexity through service and data integration. A network management middleware layer that merges low level management functionality with higher level management operations to resolve the problem of heterogeneity was proposed. A prototype was implemented using Web Services and a testbed was developed using trouble ticket systems as the management application to demonstrate the functionality of the proposed framework. Test results show the correcting functioning of the system. It also concludes that the proposed framework fulfils the principles behind the SOA philosophy.
