Aims to develop a robust methodology to provide quantified
guidance relating to the impact on reliability of changes to
T&R 5-5A being presently considered by the industry. This will
facilitate the industry consensus necessary for such changes to be
fully incorporated into jack-up site assessment. Covers phase I of
the work. Reviews previous pushover and reliability analyses, and
areas were modelling 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 modelling is outlined. Two rig/location cases were
selected that were as close to the T&R 5-5A calibration cases
as changes to T&R 5-5A on unity checks were evaluated based on
such cases.
