Abstract
A subsea pipeline has a steel pipe surrounded by a thermally-insulating coating system having at least one thermal insulation layer. The thermal insulation layer has a thermally-insulating matrix in which elongate tensile elements of a thermoplastic polymer, such as monofilament yarns, are embedded. The pipe is preheated to promote bonding between the matrix and the elongate elements and between successive layers of the coating system.
