An insulated hollow structure (1, 1a, 1b), such as a pipe (1a) or a tank (1b), for storing and/or guiding a fluid having a temperature above 140°C during the storing and/or guiding in said insulated hollow structure (1, 1a, 1b) is provided. The insulated hollow structure (1, 1a, 1b) comprises insulation layers (3, 4) enclosing an inner wall (2) of the hollow structure (1, 1a, 1b), which insulation layers (3, 4) comprises a first inner insulation layer (3) and a second insulation layer (4). The first insulation layer (3) comprises an aerogel based insulation material which has been applied in a liquid state to a surface (2a) of said wall (2) of the hollow structure (1, 1a, 1b) and then subsequently cured after being applied, before providing a second insulation layer (4). The second insulation layer (4) is a spray foam insulation layer enclosing the first inner insulation layer (3) and the inner wall (2) of the hollow structure (1, 1a, 1b). The invention moreover relates to use of an insulated hollow structure in the maritime environment, and a method of providing an insulated hollow structure. |
