In a nutshell, wrapping is a way of bandaging pipes that have sustained damage, corrosion or holes.
“The service is very much in demand by the oil and gas industry on the NCS at the moment, although the method has been in use for years and is well documented and approved,” says Beerenberg project manager Bertil Bargård.
No hot work required
The method, which has been certified by DNV GL and approved by Equinor, is fairly straightforward. If you have a hole or some other visible damage, you simply insert a piece of “chewing gum”, which then expands greatly. Next, you fit a bandage to the area. The application method is adjusted according to the pressure and temperature in the pipe.
“The entire process is completed with no hot work involved, so it’s ideal for maintenance jobs on plants in operation. We already have certified personnel working offshore, including surface treatment engineers and rope access technicians,” Bargård says.
Hard as steel
Beerenberg is attracting much interest when demonstrating its wrap model.
“When people can touch and feel the product they realise that the wrap is as hard as steel and of a high quality. It’s highly convincing. It’s also flexible in use. Depending on application method and material, it can have a proven lifetime of two to 20 years. So it can be used for everything from quick fixes to long-term solutions.”
More than just pipes
Wrapping can be used for more than just bandaging pipes. For example, the method can be used to reinforce both tanks and structures when they need to be upgraded.
“The method has great potential, but Beerenberg have chosen to focus on pipes for the time being. Still, I envisage that the services we offer in this area will expand fairly rapidly,” Bertil Bargård concludes.
