Abstract: A heat-delivery apparatus (12) heats a heat-shrinkable sleeve (10) on a pipe (2). The heat-delivery apparatus (12) includes one or more heater elements (20) which define an interior heating surface that surrounds the sleeve (10). An air space is thus defined between the exterior of the sleeve (10) and the interior heating surface. The flow of air, that would otherwise be generated by the step of applying heat, within said air space is controlled or restricted for example by means of fins (50, 50s, 60) that control or restrict the airflow, fully or partially sealing the air space with one or more sealing members (70), or fans (80) that generate an opposing airflow (82).

Abstract: A method of applying protective sheeting of polymer material to a pipeline, such as on a J-lay rig, includes the steps of driving a carriage along an annular path about the pipeline; extruding and simultaneously winding the protective sheeting about the pipeline via an end extrusion die fitted to the carriage; compressing the protective sheeting on the pipeline, directly downstream from the end extrusion die, so the protective sheeting adheres to the pipeline; and controlling the drive, extrusion, and compression steps so that the time lapse between expulsion of a cross section of protective sheeting from the end extrusion die and compression of the same cross section of protective sheeting is less than one second.
