Fluid transport in offshore pipelines is vulnerable to the risk of viscosity reduction and clogging. Thermal insulation is, therefore, becoming a critical factor in the development of pipelines. This can be carried out by coating with polymer foams or by using double wall pipelines between which a super- insulator subjected to a variable pressure is inserted.

 

Presans assisted Subsea 7 in the formulation of the problem centered on thermal super-insulators, in order to allow a comparison between the solutions already used internally and all the insulation technologies including their fields of application and their performances.
