  • France: JIP to address deep-sea flowline thermal insulation

    The thermal behavior of fluid transport pipelines must be increasingly taken into account in new field developments, to prevent production of waxes or hydrates. The deepest developments (water depth >1,500 m) are particularly sensitive to these problems, and solutions are needed for such depths. The current solutions – coated pipe, pipe-in-pipe, syntactic foam – have to be adapted to ultra-deep water, as there are limitations in terms of thermal conductivity, hydrostatic pressure and installation possibilities. Thus, more-satisfactory solutions have to be found for the different installation procedures currently in use. In the framework of the CLAROM (club for research on offshore structures), IFREMER, on behalf of a group of companies including Stolt Offshore, Bouyges Offshore, TotalFinaElf, IFP and BV, managed a research project on the evaluation of insulation materials usable for ultra-deep pipelines (1999 – 2002).
