LECTURE TOPIC: Safety of Offshore Structures and Operations in the Oil and Gas Energy Sector.
The lecture will be followed by a drinks reception in the James McKay Hall within the Kings Conference Centre.
This event is free. Book for this event.
The Lloyd's Register Educational Trust (The LRET) funds education, training and research programmes in transportation, science, engineering, technology and the safety of life, worldwide for the benefit of all.
An overview of important developments regarding safety management of offshore structures and operations in the oil and gas energy sector is given. Based on relevant experiences with accidents, the hazards and means to control the associated risk are categorized from a technical-physical as well as human and organizational point of view. A comparison between the safety management approaches in different industries operating at sea – such as shipping, oil and gas, renewable energy, food production, coastal civil engineering is briefly touched upon.
Structural risk relates to extreme environmental and accidental events, as well as structural degradation and can be controlled by use of adequate design criteria, inspection, repair and maintenance as well as quality assurance and control of the engineering processes. Such measures are briefly outlined, while emphasis is placed on a quantitative design approach for dealing with structural robustness. In this connection, the inherent differences in the robustness of various structural concepts are pointed out. The application of risk and reliability methodology for safety management of novel and mature systems is briefly reviewed.
Marine operations are becoming increasingly important in connection with transport and installation of offshore facilities, drilling operations, subsea operations, offloading, anchor line deployment etc. Marine operations involve hardware, software (i.e. in automatic controls), and especially human factors, and the inherent risk can be controlled by adequate planning of the operation and training of operators. Examples of assessment and mitigation of the risk in marine operations will be given.
Torgeir Moan is Professor of Marine Technology, and since 2002 the Director of the Centre for Ships and Ocean Structures (CeSOS) at the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway. CeSOS involves approximately 90 full- and part-time researchers. Dr. Moan has served on the Royal Inquiry Commission of the Alexander L. Kielland accident and other accident inquiries and serves on various advisory committees for industry and standardization organisations. He has been adjunct professor at the National University of Singapore and is honorary professor of two major Chinese universities.
Professor Moan’s main disciplines are structural analysis and design, with a focus on safety. He has carried out research as well as engineering design and analyses of innovative concepts for high speed vessels, LNG and FPSO ships, oil and gas platforms, floating bridges as well as offshore wind turbines.
Professor Moan has authored or co-authored about 500 journal and conference publications, and, with Professor Næss, a book on “Stochastic dynamic analysis of marine structures” (Cambridge University Press). He has supervised more than 400 MSc thesis students and 59 PhD students. Since 2001 Professor Moan has been editor of the Journal of Marine Structures and he serves on the editorial board of several other journals.
Professor Moan has delivered approximately 30 invited keynote lectures at major conferences and has received several international awards, including the Bruce Wallace award at Massachusetts Institute of Technology, the Statoil Research Prize, the James W. Rice award of ASME, the Offshore Energy Center Hall of Fame Award (Houston), SOBENA Award (Brazil), ISOPE Award and the Petroleum Safety Authority Award. He has been elected Fellow of three Academies in Norway and the Royal Academy of Engineering, UK, and is a fellow of several professional societies.
