Abstract
The present invention relates to a pipeline junction coating between the joined ends of two coated metallic pipeline sections, the coating comprising an elongate body able to extend over the joined ends of the coated pipeline sections, and having a variable end profile at one or both ends. The pipeline junction coating is for coating field joints of coated rigid pipelines, as used in the subsea oil and gas industry.
Claims21
A pipeline junction coating between the joined ends of two coated metallic pipeline sections, the coating comprising an elongate body able to extend over the joined ends of the coated pipeline sections, and having a variable end profile at one or both ends.
A method of coating a pipeline junction between two coated metallic pipeline sections comprising at least the steps of:
- (a) positioning a mould tool around a field joint to define a mould cavity, the mould tool having one or more shaping tools with a variable profile at one or both ends of the mould tool;
- and
- (b) injecting a moulding material into the mould cavity to form a pipeline junction coating having a variable end profile at one or both ends.
