Gas Hydrates
SINTEF, and in particular, the Multiphase Flow Laboratory, has more than a decade of experience with hydrate phenomena. Our work has covered the entire range from basic studies to practical implementations of know-how in field operations, as well as consultancy projects on hydrate protection and mitigation for large deepwater developments. Gas Hydrate is one of the potentially most critical factors in flow assurance over long distances, and in harsh environments like deep water. Our laboratory is unique in that it can simulate these conditions accurately for most industrial conditions.
Over the last couple of years, we have put lots of effort into develop our patented "Cold Flow" concept – a radical flowline solution allowing subsea systems to operate far within the hydrate stability envelope without using chemicals or complex systems to protect against hydrate plugging. Together with BP, we are currently continuing this work towards actual field installation and commercialisation.
