Vikotherm R2, rubber-based subsea thermal insulation, by Trelleborg has a three-layer coating system that provides passive fire protection (PFP), corrosion protection and thermal insulation properties
The rubber is chemically resistant to most corrosive liquids, gases, salt water, ozone and UV-light; all of which are corrosive agents commonly encountered in the offshore environment. In addition, the material’s operating temperature ranges from -49°C to 155°C.
Designed to last a minimum of 30 years, the material is maintenance-free, eliminating the need for future replacements or rectifications. It is practically incompressible and resistant to both seawater and impact, effectively withstanding low and high temperatures and giving corrosion and mechanical protection.
Trelleborg’s offshore operation has recently secured a contract to supply its solution for use on the new Johan Sverdrup oilfield in the North Sea, off Norway.
Contracted by Kvaerner, Trelleborg’s offshore operation in Norway will supply its Vikotherm R2 thermal insulation coating to be applied to 12 risers. In addition, the company will provide corrosion coating for 195 riser guides, 40 caisson guides and 15 J-tube guides.
By working with Trelleborg, Kvaerner said that it has reduced the number of its suppliers for insulation, corrosion and fire protection requirements, which is expected to save the contractor significant time and money throughout the life of the project.
Production is expected to begin at Trelleborg’s facility in Krokstadelva in September and will continue until May 2016, according to the company.
Ben Erik Jansen, business group director at Trelleborg’s offshore operation in Norway said, “We’ve worked closely with Kvaerner on previous projects, but we take no contract for granted. So when they confirmed that we had successfully won the project for the Johan Sverdup field, we were thrilled. We are looking forward to working with Kvaerner in the coming months.”
