Design & Analysis of Floating Wind Turbine Structures

ABOUT THE COURSE

Offshore wind development has witnessed a steady growth in the last decade. Floating wind turbines are a promising new technology in the field of offshore wind power development, particularly in deep water. In recent years, significant R&D effort has been spent in conceiving floater designs that are stiff enough to accommodate wind turbines and stable enough to cope with the highly dynamic environments that prevail in deep seas. Concomitantly, great amount of time has also been invested in developing design tools to accurately model and
predict the dynamics of coupling wind turbines to floating structures. The course will deal with various aspects for the design and analysis of floating wind turbines including foundation.

WHO SHOULD ATTEND

Engineers and researchers involved in the design of offshore floating wind turbines, Contracts engineers, Wind turbine Installation companies, Team leaders, Conversion Engineers, Project engineers and managers, offshore controls engineers, Safety inspectors will benefit from attending this course. The course is innovative in both
content & structure with a careful balance of theory & practice.

CV’s of Lecturers:

Omar Khattab BSc, MSc, PhD, CEng, FRINA,MSANJ has been an independent consultant since 2007 working for various clients including Brooks Bell Jarret Kierman,Safety at Sea Ltd., Milford Haven Port Authority, Svitzer Marine Ltd., Port of Belfast, Lloyds Register EMEA, Clydeport Operation Ltd. and SACH Solicitors amongst others. Prior to becoming an independent consultant, Dr. Khattab was a lecturer at Alexandria University, Egypt, where he gained his undergraduate degree, for 5years. He obtained his MSc degree in Hydrodynamics from Alexandria University and his PhD from Japan in 1979. He then spent 5 years with the British Ship Research Association (BSRA) as Principal Research Officer at the Naval Architecture Department. During 1988-1993, Dr. Khattab worked in Senior and Management positions at BMT in the Ship Performance Department, the Fluid Dynamics Group and the Hydrodynamic Services at BMT CORTEC Ltd. After this spell at BMT, he returned to lecturing at Southampton Institute where he began as Senior lecturer for 2 years and was quickly promoted to Head of Maritime Technology. Dr. Khattab then moved to Brookes Bell Jarret Kirman in 2000 before beginning work as R & D Manager at Safety at Sea Ltd where he stayed until he began consultancy work. Dr. Khattab is a Fellow of Royal Institute of Naval Architects, a member of Japan Society of Naval Architects as well as a member of Kansai Society of Naval
Architects. His areas of expertise include Ship Grounding and Collision, Hull Form Design, Fluid Mechanics, Ship Construction and Ship hydrodynamics amongst many others. His Consultancy work has included the Investigation of handling behaviour of new generation of Cruise Liners in Miami Harbour and the Design of berthing Jetty for Svitzer tugs in Milford Haven to name but a few.
Mr Trevor Hodgson is in his second spell with Atkins, having been with them in total for well over thirty years. He has spent the majority of this time working in offshore-related areas, both in the technical execution of this work and in the management of teams of engineers to achieve specified goals. He has extensive experience of conceptual and detail design for jacket structures and topsides, including over thirty platforms in SE Asia, and concrete structures in the North Sea and worldwide. His experience encompasses both shallow and deeper water platforms of steel and concrete construction, drilling riser and conductor analysis, semi-submersible and FPSO vessels, high-speed aluminium surface craft, and even peer review for the nuclear industry. He has recently been involved in the development of concepts and detailed designs for the offshore renewable energy market, including wind, wave and tidal energy conversion devices, most recently Wind Turbine Generator (WTG) substructures. He is highly experienced in the application and interpretation of advanced finite element analysis methods for the design process and has used this experience to great effect in the development and support of engineering software, primarily the ASAS: OFFSHORE suite for the oil and gas industry, now part of ANSYS. He is the author of numerous texts on structural design and analysis, was convenor of a panel covering Structural Analysis of Fixed Concrete Platforms for the ISO standard on offshore installations, and lectures for ASRANet and the Universities of Glasgow and Strathclyde on offshore structures and renewables.
