Advanced Insulation’s ContraTherm® thermal insulation system has been specifically developed to meet the need for a resilient material capable of tolerating the high temperature and pressure extremes required for offshore oil and gas production.
Insulating subsea equipment reduces the cooling of reservoir fluids and maintains them above temperatures at which waxes and hydrates may form, thereby minimising the risk of diminished flow rates and blockages.
Insulation may be applied to subsea equipment including but not limited to pipelines, Xmas trees, manifolds, jumper spools, pipe line end terminations and flange connections. As oil and gas production extracts fluids of ever increasing temperatures from deeper waters and at longer tie-back distances from the host structure, the benefit of insulating subsea equipment becomes increasingly apparent.
With fluid temperatures approaching 180ºC (356ºF) and at water depths approaching 3,000 msw (10,000 fsw) the need for a high temperature, high pressure insulation material capable of withstanding such environmental extremes becomes a consideration of paramount importance.

Silicone resins offer a highly flexible, high temperature insulation system that is fast becoming the recognised solution for dynamic application service. Advanced Insulation recommends the C25 Series for service on dynamic applications such as production jumpers, tie in spools and steel risers.
Phenolic resins are widely used in high temperature applications and are the acknowledged choice for elevated service temperatures. Advanced Insulation recommends the C55 Series for service on less dynamic applications such as Xmas trees, manifolds, supported jumpers and pipeline end terminations.
