  • Patent number: 9903525
    Abstract: The present invention provides an insulated fluid conduit useful in facilities in which a hot fluid susceptible to one or more deleterious phase changes in response to heat loss to a cold environment is transported. Such conduits may be particularly well suited to improve thermal control in subsea hydrocarbon production operations. The fluid conduit includes an inner first insulating layer containing a first polymer matrix, and a first phase change material undergoing a phase change at T1. The fluid conduit includes an outer second insulating layer containing a second polymer matrix, and a second phase change material undergoing a phase change at T2, wherein T1 is greater than T2. One or more barrier layers inhibit migration of the phase change material from the insulation layers and into the environment. In one or more embodiments, the phase change material is present as a microencapsulated phase change material.

  • Patent number: 8997796
    Abstract: A durable, semi-rigid, single-layered flexible duct having a sleeve made of a single aluminum layer and a resilient wound element disposed at the mid-point of the overlap region of the aluminum layer. The wound element imparts corrugations to the sleeve, such that the duct is extendible between a compacted configuration suitable for storage and for shipping and an extended configuration suitable for installation in a gas transport arrangement. Closely and evenly-spaced ridges that are situated in between the corrugations, add rigidity and durability to the duct. The inward-facing surface of the aluminum ribbon is substantially smooth and featureless except for the helical corrugations imparted by wire winding and the closely and evenly-spaced ridges. The aluminum sleeve is of a predetermined thickness rendering the duct substantially rigid when in an extended configuration and enabling the duct to maintain its substantial rigidity upon extension from a compacted configuration.
