Marilm Field: The Evolution of Subsea techniques and hardware

摘要

As the development of Marlim field was planned back in the mid 80's the challenge was to develop subsea hardware and techniques that would allow completion of 148 wells in water depths ranging from 600 to 1100 meters. As the first Guidelineless Subsea Trees were designed and manufactured the key to sucess was, indisputably, the flowinge connection method. Starting with the Lary Away method, a natural extension of the guideline concepts, Petrobreas is now purchasing subsea trees with a 4th generation flowline connection method.
