Subsea Thermal Insulation
Due to the possible risk of clogging of subsea oil and gas piping by wax and hydrate formation, thermal insulation is necessary and recommended especially for deep-sea projects. The need for thermal insulation is generally governed by oil and gas temperature and the distance from the subsea well to the platform or FPSO.
Trelleborg's Vikotherm™ subsea thermal insulation is a solid rubber-based coating, practically incompressible, seawater resistant, impact resistant, has very good thermal insulation properties, and provides maximum corrosion protection. It is designed to last the life of the subsea projects (20~40 years), is maintenance free, and will normally never be replaced.
The Vikotherm™ insulative elastomer coating system is a development based on ordinary rubber technology. The Vikotherm™ material consists of a rubber elastomer chemically modified to give a very high insulating property while maintaining its inherent rubber properties as far as sea water resistance, pressure resistance, mechanical properties and temperature are concerned.
