Pipe-in-pipe (PIP) flowlines have been widely arranged in offshore oil and gas fields for transportation, to achieve a significant thermal insulation capacity outstanding resistance external loads. However, the lateral indentation mechanisms of these multilayer pipelines are more complicated than those single-layer pipelines. In this paper, change deformation laws PIP structure were studied by ...

This paper empirically explores the concept of co-materialization to explain the digital innovation dynamics in offshore petroleum production. The central insight developed is that the very nature of subsurface processes and phenomena that may be monitored and controlled is transformed as offshore petroleum production is digitalized. The paper shows how digital technologies are intrinsic to thi...

Environmental context The oil and gas industry has a significant liability in decommissioning offshore infrastructure. Following decommissioning, subsea pipelines could be left on the seabed to provide artificial reefs. Mercury is contaminant of concern which remain within pipelines. There are gaps our knowledge how mercury moves through marine environment. We review current science identify fu...

There has been a steady growth in the length of pipelines over past 45 years, with 6000 operating platforms extracting oil. Several facilities would reach their operational life, which can no longer be economically viable for production and will eventually undergo decommissioning procedure. Almost 3000 petroleum industries likely decommissioned worldwide next 17 years. By 2030, total cost globa...

In the past few decades, there have been many numerical studies on scour around offshore pipelines, most of which concern two-dimensional setups, with pipeline infinitely long and flow perpendicular to pipeline. Based Ansys FLUENT solver, this study establishes a tool three-dimensional pipelines finite lengths. The user-defined functions are written calculate sediment transport rate, update bed...

Offshore pipelines are occasionally exposed to scouring processes; detrimental impacts on their safety inevitable. The process of propagation around offshore is naturally complex and mainly due currents and/or waves. There a considerable demand for the safe design phenomena. Therefore, patterns must be focused on. In present research, machine learning (ML) models applied achieve equations predi...
