Patent number: 11313507Abstract: A pipeline having a series of interconnected pipe sections forming Field Joints, each pipe section having a coating with a thermal insulation layer which extends over a substantial portion of a length of the pipe section, and an anti-corrosion layer situated underneath the thermal insulation layer. The pipeline has a Field Joint Coating (FJC) at connection regions where ends of the adjacent pipe sections are interconnected. Each FJC has an anti-corrosion coating layer, an intermediate coating layer of a thermoplastic material which covers the anti-corrosion coating layer, and a FJC thermal insulation layer which covers the intermediate coating layer.Type: GrantFiled: October 2, 2018Date of Patent: April 26, 2022Assignee: Shawcor Ltd.Inventors: Helen Rose Boyd, Lara Elizabeth Wills
