(formerly the Marine Pipeline Engineering Course)
The course will provide a complete and up-to-date overview of the area of subsea pipeline engineering, taking delegates through the pre-design phase, design, construction, installation, operation and maintenance. It will give a complete picture of the work of design engineers and pipeline construction companies, using actual case studies from around the world to highlight the topics discussed. While the course requires no previous experience, this is not a superficial overview. The lecturers are experts in their fields and have vast experience in lecturing on the subject of subsea pipeline engineering. Places will be strictly limited to ensure maximum individual attention. All delegates will receive a full set of lecture notes providing an invaluable reference for use after the course.
Who should attend
Engineers from oil & gas companies, construction companies, pipe and service suppliers and regulatory authorities, who are newly qualified, have recently moved into pipeline engineering or hold broad responsibilities that include pipelines.
Course Documentation
Participants receive a sturdy ring binder containing more than 700 pages of text and illustrations supporting the lectures and providing an invaluable reference source after the course.
In addition, each participant will receive a copy of the newly published 650pp. reference book Subsea Pipeline Engineering by Andrew Palmer and Roger King.
Continuing Education
On completion of the course, participants will be eligible to receive 2.6 Continuing Education Units. (CEU’s).
Lecturers
Dr. Roger King has over 30 years’ experience of corrosion in the oil, gas, civil, and nuclear industries. Dr King ran the premier microbiological corrosion group at UMIST for seven years; the group accumulated over 150 man-years of research into corrosion by micro-organisms. The group published over 100 theses, dissertations and papers on bacterial corrosion and its prevention and treatment.
He also has specialist knowledge of sweet and sour corrosion and its prevention by chemical inhibition, monitoring of corrosion and the design of efficient cathodic-protection systems for flowlines, structures, and seabed installations. He has been an independent consultant since September, 1989, and prior to this was a founder member of the Corrosion and Protection Centre Industrial Service (CAPCIS) at the University of Manchester, UK.
Professor Andrew Palmer is currently Keppel Chair Professor in the Centre for Offshore Research and Engineering of the Department of Civil Engineering at the National University of Singapore. He retired in 2005 as Research Professor of Petroleum Engineering at Cambridge University in the UK. Professor Palmer is a Fellow of the Royal Society, a Fellow of the Royal Academy of Engineering, a Fellow of the Institution of Civil Engineers, and current chairman of the DNV Pipelines Committee. He is the author of three books and more than 180 published papers on pipeline engineering, structures and geotechnics, including the textbook Subsea Pipeline Engineering, which was co-authored with Dr. Roger King.
Professor Márcio Almeida is Professor of Geotechnical Engineering at COPPE, Graduate School of Engineering, Federal University of Rio de Janeiro (UFRJ). His main areas of interest include embankment on soft clays, unsaturated soils, environmental geotechnics, and pipeline geotechnics. Prof. Almeida was head of the Civil Engineering Department at UFRJ from 1995 to 1997 and head of the Environmental Engineering Group from 1997 to 2000. He consults to industry extensively and has published more than 150 papers. In 1998 he received the Terzaghi Award from the Brazilian Society of Geotechnical Engineering.
Continuing Education Units (CEUs)
On satisfactorily completing the course, participants will be eligible to receive 2.6 CEUs.
