Reel pipe coating and laying vessel and process

摘要

A pipeline vessel for laying out and coating a pipeline from a storage reel onto the bottom of a body of water. The vessel equipment provides for both straightening and tensioning of the pipeline as well as coating with a wide range of concrete and/or polymer coats. Both extrusion type thermoplastic coatings and reacted in situ thermoset resins are employed. The process of laying a relatively inflexible pipeline from such a reel pipelaying vessel and coating the pipe as it is laid out is also provided.
