Project Number 551
Date of Summary February 13, 2007
Subject Assessment of Drilling and Workover Rig Storm Sea Fastenings on Offshore Floating Platforms During Hurricane Ivan
Performing Activity OTRC/Technip
Principal Investigator Dr. E.G. Ward
Contracting Agency Minerals Management Service
Estimated Completion Completed
Description Drilling and workover rigs on Floating Production Systems (FPSs) are fastened to the decks of offshore structures sea fastenings to prevent movement during hurricanes. During Hurricane Ivan, a number of drilling or workover rigs shifted. These movements are being assessed along with the current design philosophy and criteria for storm sea fastenings, rig and storm sea fastening installation practices, and onboard storm operational practices to ready FPSs for a hurricane. Results will provide information that can be used to assess any needs to revise tie-down criteria or practices.
