Risk-based Reliability Assessment of Subsea Control module for Offshore Oil and Gas production [PDF]

open access: yes, 2014
Offshore oil and gas exploitation is principally conducted using dry or wet tree systems, otherwise called the subsea Xmas tree system. Due to the shift to deeper waters, subsea production system (SPS) has come to be a preferred technology with ...
