Spar Floating Drilling, Production and Storage System: History and Evolution
Ed Horton, President, Horton Wison Deepwater
Mr. Horton is one of the most recognized inventors in the offshore business, having invented two standard deepwater concepts (Spars and Tension Leg Platforms), representing the majority of floating drilling and production units currently operating. Over 2 billion barrels of oil have been produced through facilities that depend on his patents.
The idea of using a Spar for a drilling, production and storage system originated in the early 1980s. After numerous studies and joint industry projects, Oryx Energy and CNG installed the first actual unit in 1996. As of this writing, 17 spars are installed or under contract. All of these units are in the deepwater of the Gulf of Mexico except for one in the South China Sea in East Malaysia. There are now three generations of the Spar: the Classic, Truss and Cell.
This presentation reviews the evolution of the past and present spar designs, focusing on the progression of work that ultimately led to the application of this new concept to the oil industry. This includes the evolution from “classic” deep draft caisson designs to the Truss and Cell Spars. New developments on the drawing board will be highlighted.
Symposia Highlights
Offshore Geotechnics Symposium
Offshore geotechnics has matured into a discipline in its own right. New developments and knowledge are following at a rapid pace as seabed utilization in shallow waters increases and spreads to ever deeper parts of the ocean. Academia, government, and private enterprise across the globe continue to contribute new advances in areas such as anchors, caissons, piles, seafloor hazards, field investigation, fluid-soil-structure interaction, trenching, pipelines, seabed earthquake engineering, and mining. This symposium provides an opportunity for researchers and practitioners to share their findings, exchange information, and explore avenues of cooperation. It includes 28 papers and 7 sessions.
Materials Technology Symposium
The Materials Technology Symposium will feature presentations on Advanced Materials for Arctic Pipelines, and a workshop on Strain Capacity of Pipelines.
Pipeline & Riser Technology Symposium
The PRT Symposium will have 120 presentations covering different aspects of rigid and flexible pipes design, as well as new innovative techniques for installation and inspection. The growing interest in the pipe-soil interaction will be covered in six dedicated sessions.
Ocean Space Utilization Symposium
One of the OSU Symposium topics will be Deep-sea mining, which is attracting attention given the recent rise in the price of metals. Development concepts, system design, economical feasibility, environmental impact and assessment will be presented in the Deep-sea Mining sessions of the OSU Symposium.
T. Francis Ogilvie Symposium on Marine Hydrodynamics and Fluid Mechanics
T. Francis Ogilvie is one of the most recognized names in marine hydrodynamics and this Symposium will honor his important educational and research contributions to the fields of naval hydromechanics, free surface and ocean engineering fluid mechanics. Prof. Ogilvie's personal contributions include rational strip theory and time domain ship motions, singular perturbation methods and second order motions and loads. In addition Prof. Ogilvie is well known to have mentored many in his various positions to produce high quality research and instruction.
After completing his PhD at UC Berkeley under John Wehausen, Prof. Ogilvie's career included time at David Taylor Model Basin (DTMB), ONR London, University of Michigan and MIT. At DTMB he led an active group of researchers who included Nick Newman and the late Ernie Tuck. As Chairmen at Michigan he transformed the naval architecture department from an industry experienced based education to a solid grounding in applied mechanics. As Chairmen at MIT he led the transformation of the undergraduate program from naval architecture to ocean engineering. After leaving MIT he was honored with a lectureship for young investigators. In addition, he has been honored by SNAME and the US Coast Guard for his important contributions to naval architecture and ocean engineering education.
His contributions to our field are extensive and exemplified by his 1964 ONR hydrodynamics symposium paper Recent Progress in Ship Motions. Francis Ogilvie’s career ranged from David Taylor Model Basin, University of Michigan and Massachusetts Institute of Technology. This paper has been referenced by several of the symposium’s authors.
We expect approximately 40 papers in 10 sessions dealing with a wide-range of topics. In addition, we will have a symposium dinner to give the participants an opportunity to socialize. We look forward to a great symposium and hope you all can attend.
Alaa E. Mansour Symposium on Ship and Offshore Structural Design
This symposium will honor the important educational and research contributions of Professor Alaa E. Mansour to the fields of ship and offshore structural design. Dr. Mansour is a Professor of Ocean Engineering in the Department of Mechanical Engineering of the University of California at Berkeley. He was the Chairman of the Naval Architecture and Offshore Engineering Department at the University of California, from 1985 to 1989, and chaired the Executive Committee of the Ocean Engineering Graduate Program at Berkeley from 2002 to 2005. He received his Bachelor of Science degree in Mechanical Engineering from the University of Cairo and has M.S. and Ph.D. degrees in Naval Architecture and Offshore Engineering from the University of California, Berkeley. Dr. Mansour was awarded the Davidson Medal by the Society of Naval Architects and Marine engineers, and is the recipient of an Honorary Doctoral degree from the Technical University of Denmark. He is a co-author of the book titled ‘Strength of Ships and Ocean Structures’ published by The Society of Naval Architects and Marine Engineers, New Jersey, 2008.
Over twenty papers in various areas of interest will be presented at this symposium by well known researchers. The following are some of the technical areas to be covered.
• Condition Assessment of Aged Structures
• Limit States and Reliability Based Approaches
• Nonlinear Structural Mechanics and Analysis
• Experimental Techniques, such as for Fire, Blast and Ultimate Strength
• Mathematical Models in Age-Related Degradation
We sincerely hope to see you at this symposium honoring Prof. Mansour for his long standing and important contributions to naval architecture and offshore engineering.
