Abstract
Deep-sea oil and gas production normally involves the use of flexible risers that comprise a metal carcass with a large number of enveloping layers that safeguard the integrity of the pipe system. The flexible risers are hung from a floating platform and may be supported by several floating buoys to cushion the significant movements caused by waves and ship swells.In some gasfields production a small quantity of fine sand is also extracted and this may cause the metal inner carcass of the risers to erode, which could ultimately lead to a gas leak, something that must be avoided at all times.Shell asked TNO to carry out experiments to reveal the extent of this erosion, and how this was linked to the velocity of the gas and even the amount of liquid in the riser. While there are models, these are such a simplification of the actual situation that verification by experimentation is deemed necessary.
