Design and Analysis of Floating Structures

Access Activity

Overview / Abstract:

Floating structures have enabled drilling and production in the deepest waters of the Gulf of Mexico and elsewhere in the world. The proper design of these platforms is essential for the survival of the risers and the safety of the people that operate the platforms.

This course provides an introduction to the fundamentals involved in floating structure design: hydrostatics and stability, hull structure, global design and sizing, mooring, global responses and an overview of structure fabrication, transportation and installation methods. The scope of specific platforms include: semi-submersibles, tension-leg-platforms (TLPs), spars, and FPSO (ship-shaped). The content is based largely upon application of Rule and Recommended Practice-based methods. The use of “first principles” in the design is discussed as well.

You Will Learn To:
- Identify the functions and salient design drivers of different floating structures
- Configure floating structures and moorings to meet their function, safely
- Identify the methods for design and analysis of floating structures
- Recognize applicable Industry Standards, the role of Classification Societies, and application of the Rules, particularly, to hull stability, structure, and mooring design

Who Should Attend
This course is intended for naval architects, civil and mechanical engineers interested in learning more about the methods for design and analysis of floating offshore platforms, specifically production and drilling platforms. The course would be particularly useful for engineers working on or planning on working on deepwater projects involving risers, moorings and floating structures. Some background knowledge of basic fluid mechanics and strength of materials is necessary.

John Halkyard, Sc.D., P.E., is the owner of John Halkyard & Associates (JHA), which provides concept design and analysis services for floating offshore facilities for oil & gas drilling and production, ocean mining, and alternate energy projects. He is also a Visiting Professor of Maritime Technology at the National University of Singapore, where he teaches courses on floating structure design, moorings and risers, and supervises research. Dr. Halkyard has over 40 years’ experience in deep ocean system development, including deep ocean mining and floating production systems (FPS). He was one of the original architects for the successful Spar concept for deep-water oil production.

Dr. Halkyard worked as Chief Ocean Engineer for Kennecott Exploration, Inc., where he was responsible for developing and testing systems for the recovery of manganese nodules from water depths of 4500 meters. He then established and managed his own consulting company, specializing in design of deep water oil and gas projects. In 1984, he merged his consulting business with Arctec Offshore Corporation and served as the Vice President in charge of hydrodynamic model testing of offshore projects. In 1988, he joined Deep Oil Technology, Inc. (DOT), and was instrumental in developing the world’s first floating spar drilling and production system. Dr. Halkyard joined Aker Maritime, Inc. in 2000 as Vice President in charge of floating systems R&D. He retired from Technip as Chief Technical Advisor for Floating and Fixed Facilities Product Group in 2007.

Dr. Halkyard’s current projects include Ocean Thermal Energy Conversion (OTEC) platforms, floating wind energy, research on the dynamics in waves and currents of multiple floating platforms in close proximity, and platform vortex induced motions. He is also a consultant to the Malaysian Oil Company, Petronas, where he assists in Technical Professional Career Progression activities, including training. Professor Halkyard is a Life Fellow of the American Society of Mechanical Engineers (ASME), and currently serves on the Board of the International Petroleum Technology Institute of ASME.

Dr. Halkyard is an Associate Editor of the Journal of Offshore Mechanics and Arctic Engineering, and has published extensively on the design of floating structures, including the chapter on floating structure design in the Handbook of Offshore Engineering (Elsevier, Subrata Chakrabarti, Ed.). He holds six patents related to offshore floating systems. Professor Halkyard has served as Chair of the International Professional Advisory Panel for the Department of Ocean and Resource Engineering at the University of Hawaii, and has previously served on Visiting Review Committees for MIT and the US Naval Academy. He has also served on the Marine Board of the National Research Council, National Academy of Engineers.

Dr. Halkyard holds a B.S. degree in Engineering Sciences from Purdue University, an SM in Engineering and Sc.D. in Ocean Engineering from the Massachusetts Institute of Technology.

Steve Perryman, P.E., currently represents Stress Engineering Services, Inc., as a Senior Staff Consultant. Stress Engineering is well known for its work on floating offshore platforms, risers, subsea equipment and other drilling and production components. Mr. Perryman has over 40 years of experience in the offshore industry, and is currently involved with several Gulf of Mexico floating platforms, either in the design or the integrity management stages. His experience has spanned from fixed to floating platforms, from detailed design engineering to construction and installation, from research and development to project execution and from engineering contractor to operator. Mr. Perryman was one of the original architects for the successful Spar concept for deep water oil production and was the delivery manager for the largest Spar installed to date.

Mr. Perryman began his career as a structural design engineer of fixed platforms, including Bullwinkle, with Crest Engineering, Inc. and Lowell Johnston and Associates before joining Amoco at their Tulsa Research Center, where he championed the development of the Spar concept through participation in several joint industry projects, which included several model tests. Later, he became the lead floating system engineer for several TLP and Spar deepwater projects, and finally, the delivery manager for BP, for a Spar in the Gulf of Mexico. Prior to joining Stress Engineering, he was instrumental in establishing an in-depth integrity management system at BP for seven deep water floating drilling and production platforms.

Mr. Perryman is the author of several technical papers on deep water floating platforms and was the keynote speaker at the 2004 ISOPE conference in Toulon, France. He has also been the featured speaker at several Spar breakfasts, held in conjunction with OTC. He has been a member of ASME for over 40 years and has served on several API task groups, sub-committees and committees. He also served for many years on the ASCE program committee for OTC. He is a registered Professional Engineer in the State of Oklahoma.

Mr. Perryman holds a Bachelor of Science degree in Mechanical Engineering from the University of Oklahoma and a Master of Science degree in Civil Engineering from Oklahoma State University.
