Associated capabilities


Stork was contracted to repair the perforation on a 4” closed drain spool elbow located on Nexen’s Scott installation. The surface of the 4” closed drain spool elbow was hand prepared by Stork’s multi-skilled technicians. All voids were then filled with epoxy putty to smooth the surface area. Stork’s innovative pipe repair solution; PowerSleeve was then utilized. PowerSleeve’s engineered composite reinforcement was selected because of its 100% solids epoxy impermeable barrier. This combined with the strength of its custom E-glass and Kevlar® fabric made it the best choice to encapsulate and reinforce the entire spool elbow.


All repair calculations were conducted in-house, providing Nexen with a fully customized rapid delivery. Stork’s technicians were able to completely cover affected area; strengthening structural integrity. All work was completed and carried out by Stork’s multi-skilled, on-board technicians. The overall cost was far less than compared to conventional repair methods.


“Further to Stork assisting Nexen with an Engineered Wrap solution to a 4” pipespool defect on the Scott platform in the closed drains system, I would like to pass on our thanks for the manner in which this was organized. To achieve our required mobilization and the fact that the Core/ LTADHOC painters had the necessary training to allow this to be applied without mobilizing any further personnel was well received due to the current POB at this time of year”.
