The Sakhalin oil and gas project is about to enter a new phase of production, with an extensive expansion project underway.
The Sakhalin II consortium is currently building two offshore platforms for the Lunskoye and Piltun Astokhskoye fields. The topside facilities of the LUN-A and PA-B platforms are being built at the Samsung Heavy Industry shipyard in South Korea.
To reduce the risk of corrosion in the harsh climate, British project management group Amec looked for a system with a non-metallic covering for insulating the pipes and specified Arma-Chek R from Armacell.
Apart from resistance to weathering - in winter temperatures fall to as low as -40degC and wind speeds reach up to 150 km/h off the coast of Sakhalin - the mechanical resistance of the material and fire behaviour tested according to the international IMO standard were of decisive importance when choosing the insulation material.
All process lines (some with trace heating), pipes of the ventilation and plumbing systems and vessels with a maximum medium temperature of 150 degC were insulated with HT/Armaflex and then covered with the 1 mm-thick, elastomeric Arma-Chek R Grey covering.
Arma-Chek R is highly flexible, lightweight and easy to install and maintain. The large quantities of insulation and covering material were delivered by the Cheondo Corporation (Geoje City, South Korea).
