Impact of Changes to T&R 5-5a on Jack-up System Reliability Level (Paperback)

Phase 1 of the work is covered in this report. A review of previous pushover and reliability analyses is given and areas where modeling improvements are recommended were identified. Factors that affect jack-up system reliability were identified and a premise for performing reliability analyses of jack-ups utilizing state-of-the-art modeling is outlined.Two rig/location cases were selected that were as close to the T&R 5-5A calibration cases as possible and the impact of proposed changes to T&R 5-5A on unity checks was evaluated based on such cases.
