A lightweight and compact insulation system that is also capable of supporting a high level of compressive load is described. The system utilizes spacers (10) to provide structural support and utilize controlled buckling of a thin protective outer carrier pipe (14) supported by spacers (10) to form strong catenary surfaces to protect insulation material underneath. The spacers may comprise an aerogel, or an aerogel may provide insulation separate from the spacer yet contained within the thin outer skin. The system will be useful for thermal management of variety of deep underwater structures such as pipe-in- pipe apparatus, risers or subsea trees for ultra-deep water oil-and-gas exploration.
La présente invention concerne un système de super-isolation léger et compact qui peut supporter un niveau élevé de charge de compression. Ce système met en oeuvre des écarteurs pour assurer un support structurel et utilise le flambage régulé d'un revêtement extérieur protecteur, mince, supporté par les écarteurs pour former des surfaces caténaires solides aux fins de la protection du matériau d'isolation sous-jacent. Les écarteurs peuvent comporter un aérogel, ou un aérogel peut assurer une isolation distincte des écarteurs cependant contenus dans le revêtement extérieur mince. Ce système peut s'avérer utile pour la gestion thermique de diverses structures immergées en profondeur telles que des dispositifs à double enveloppe, des colonnes de montée ou des arbres sous-marins mis en oeuvre pour la prospection de pétrole et de gaz en eaux ultraprofondes.
