An integrated FMEA and MCDA based risk management approach to support life extension of subsea facilities in high-pressure–high-temperature (HPHT) conditions
M Shafiee, I Animah - Journal of Marine Engineering & Technology, 2022 - Taylor & Francis
The majority of facilities installed in offshore oil and gas fields during the 1980s and 1990s
were designed to operate in 'normal'conditions. However, during the operational life of the …

Seabed processes: Sediment transport, scour, and sedimentation
S Draper, JM Harris, L Cheng… - Encyclopedia of Maritime …, 2017 - Wiley Online Library
In many offshore locations the seabed is mobile due to the action of currents and/or waves.
The criteria for mobility (sediment transport) is that the shear stress imparted by the currents …
