TRAINING OFFSHORE MIGAS : OVERVIEW OF DEEPWATER FLOATING PRODUCTION SYSTEMS DESIGN AND ANALYSIS


OVERVIEW OF DEEPWATER FLOATING PRODUCTION SYSTEMS DESIGN AND ANALYSIS



Floating Production Systems are becoming more common as oil discoveries are made in deeper waters. The objectives of this Workshop are to provide an introduction to the drivers for floater selection and design, and to provide an appreciation of the main tools and methods used in designing and analyzing these structures.

The programme will begin by taking a broad look at deepwater development from the standpoint of field development  planning,  processing,  and  concept  selection.  Emphasis  will  be  on  the  application  of structural and naval architectural principles, and design codes, to teh sizing and analysis of performance of moored platforms and risers. Examples will include Spars, Tension Leg Platforms, Semi-Submersibles and FPSOs.

After this course the participants should be able to identify the design drivers for the platforms and to perform high level sizing. They should understand the concept of floater stability, the different types of mooring systems and risers, and methods for their design and analysis.


By fully participating in this short course, participants with solid background in conventional offshore oil field development, planning, processing and technology application will gain ground understanding on the greater risk of deepwater oil field development, which in short it needs higher commitment, higher and world complex technology and much higher cost involvement.
In the initial part of the course for some introduction way of addressed economic magnitude, technology services and major specific equipment and source required on each stage of deepwater field from the exploration development to the production stages this short course will be beneficial for deepwater oil field engineers, planners as well as the regulator (the authorities) and oil field contractors and services companies.
