Serimax is Technip’s long-term partner for the management of spoolbase operations in Evanton, Northern Scotland. In 2011, Serimax completed welding, NDT and FJC for BP’s Devenick project, which included 13% and 25%Cr pipe grades, diameters ranging from 2” to 16”, using Pipe-in-Pipe insulation technology.

By building on welding knowledge collected and recorded group-wide, and retaining the same core welding and supervisory crew throughout production for each line, Serimax demonstrated proactivity and an effective approach in achieving strong performance: the team delivered up to 90 welds per day, and average repair rates of less than 1.5%.
