Method for thermally protecting subsea installations, and apparatus for implementing such thermal protection

摘要: Method for protecting subsea installations against cooling which leads to hydrate formation, in particular during production halts. This is achieved by thermally isolating portions of the installation (1) surrounding water (2), and particularly completely encompassing means a cap (3) seals (2). The comprises several elements each separately can be exposed internal formation. invention also apparatus, adapted cooling, involves risk An apparatus (3, 9) implementing method relatively tight-fitting encompasses at least two protected from cooling. Thus, inside kept (2) evenly distribute heat energy present under all encompassed said cap.
