gas and the ‘‘melting’’ of load-bearing or cementing solid hydrate. Here, we present findings that suggest gas hydrates may lead to a previously unknown mechanism of seafloor erosion. Gas-hydrate-bearing sub-sea ridges on the Hikurangi Margin are eroded close to the top of the hydrate stability field in the ocean. We hypothesize

Korrosion (från latinets corrodere som betyder fräta sönder) [1], frätning, innebär att ett material, vanligtvis en metall, löses upp genom en kemisk, oftast elektrokemisk, reaktion till en mer stabil form, som exempelvis oxider, hydroxider och sulfider. [2] erosion. erosion kallas den påverkan som yttre krafter utövar på landytan. Det är krafter som (14 av 94 ord) gas and the ‘‘melting’’ of load-bearing or cementing solid hydrate.

In oil and gas pipelines, the erodent can be various produced particles or liquid drops entrained in a gas carrier fluid. Because of the importance of solid particle erosion to understanding erosion‐corrosion, this chapter focuses on the factors influencing solid particle erosion and on the models developed to predict erosion …

Erosion. Erosion is a loss of original material due to solid particle impact on the material surface. Erosion is normally expressed as a rate of metal loss, usually mm/year.

During this process, cavitation bubbles focus fluid energy on the solid surface by forming high-speed jets, leading to damage and downtime of machinery. In response, numerous surface treatments to counteract this effect have been explored, including Gas‐induced erosion features in the North Sea. Martin Hovland. Statoil, P.O.
