Book Description
This book covers many different aspects of single point mooring systems. A single point mooring system is used to keep a vessel stationed at a fixed location. These vessels can for instance be a Floating Production Storage and Offloading System or Floating Storage and offloading system. Hundreds of these systems are operational today. The first part of this book shows a little history of the origins of oil and gas and the current supply and demand for oil. This book also shows some of the history of the development of the single point mooring systems. It also addresses the many different aspects of designing these types of systems. This book will also go into the detail of the hydrodynamics and loadings that act on these vessels by wind and waves and the behavior of the different types of mooring systems.

Book Description
The mooring system is a vital component of various floating facilities in the oil, gas, and renewables industries. However, there is a lack of comprehensive technical books dedicated to the subject. Mooring System Engineering for Offshore Structures is the first book delivering in-depth knowledge on all aspects of mooring systems, from design and analysis to installation, operation, maintenance and integrity management. The book gives beginners a solid look at the fundamentals involved during mooring designs with coverage on current standards and codes, mooring analysis and theories behind the analysis techniques. Advanced engineers can stay up-to-date through operation, integrity management, and practical examples provided. This book is recommended for students majoring in naval architecture, marine or ocean engineering, and allied disciplines in civil or mechanical engineering. Engineers and researchers in the offshore industry will benefit from the knowledge presented to understand the various types of mooring systems, their design, analysis, and operations. Understand the various types of mooring systems and the theories behind mooring analysis Gain practical experience and lessons learned from worldwide case studies Combine engineering fundamentals with practical applications to solve today’s offshore challenges

Book Description
Verifying the design of floating structures adequately requires both numerical simulations and model testing, a combination of which is referred to as the hybrid method of design verification. The challenge in direct scaling of moorings for model tests is the depth and spatial limitations in wave basins. It is therefore important to design and build equivalent mooring systems to ensure that the static properties (global restoring forces and global stiffness) of the prototype floater are matched by those of the model in the wave basin prior to testing. A fit-for-purpose numerical tool called STAMOORSYS is developed in this research for the design of statically equivalent deepwater mooring systems. The elastic catenary equations are derived and applied with efficient algorithm to obtain local and global static equilibrium solutions. A unique design page in STAMOORSYS is used to manually optimize the system properties in search of a match in global restoring forces and global stiffness. Up to eight mooring lines can be used in analyses and all lines have the same properties. STAMOORSYS is validated for single-line mooring analysis using LINANL and Orcaflex, and for global mooring analysis using MOORANL and Orcaflex. A statically equivalent deepwater mooring system for a representative structure that could be tested in the Offshore Technology Research Center at Texas A & M University is then designed using STAMOORSYS and the results are discussed.

Book Description
Mooring systems for floating facilities that are used offshore to produce oil and gas, consisting of individual mooring lines and foundations, are currently designed on the basis of individual components and on a case-by-case basis. The most heavily loaded line and anchor are checked under extreme loading conditions (hurricane and loop current) with the system of lines intact and with one line removed. However, the performance of the entire mooring system depends more directly on the performance of the system of lines and foundations rather than on the performance of a single component. In this study, a floating production system design originally developed by the industry consortium, DeepStar, was chosen for study. The mooring system was designed for three different nominal water depths: 1000, 2000 and 3000 m. It is a classic spar with steel mooring lines in 1000 m of water and polyester mooring lines in deeper depths. Based on simulated results of loads on mooring lines and foundations using a numerical model, reliability analyses were conducted using representative probabilistic descriptions of the extreme met-ocean conditions, hurricanes and loop currents, in the Gulf of Mexico. The probability of failure of individual mooring line components during a 20-year design life is calculated first, followed by that of a complete mooring line which consists of top and bottom chains, a steel cable or polyester rope at the middle and a suction caisson foundation, and finally that of the mooring system. It is found that foundations have failure probabilities that are more than an order of magnitude smaller than those for lines under extreme loading. Mooring systems exhibit redundancy in that the failure of the most heavily loaded component during an extreme event does not necessarily lead to failure of the system. The system reliability and redundancy are greater for the taut versus semi-taut systems and is greater for designs governed by loop current versus hurricane events. Although this study concerns about the mooring systems of a classical spar, the methodology of the reliability analysis and the conclusions made in this study may have important implications to the other deepwater mooring systems.
