Project Number 130
Date of Summary September 30, 1990
Subject Interference/Clearance Problem of Risers in Floating Production Systems
Performing Activity Brown and Root Development Inc.
Principal Investigator Dr. Farhad Rajabi
Contracting Agency Minerals Management Service
Estimated Completion Complete
Description The objective was to evaluate the interference problems and the required clearances between the long, unbraced risers to be connected to Floating Production Platforms (FPP), such as Tension Leg Platforms (TLP) and other Floating Production Systems (FPS). A parametric analysis, based on the current state-of-the-art FPS configurations were used to identify the potential for risers colliding with each other, with the FPP hull, or with mooring lines. The analysis highlighted problem areas, evaluated prevention methods, remedies and countermeasures, and identified the limits and boundaries of operations.
Progress Complete. A decision was made, not to go forward with Phase II efforts, due to findings contained in the Phase I summary report.
