METHOD OF SPOOLING A BI-METALLIC PIPE

摘要

A method of spooling a marine pipeline (90) including a plurality of bi-metallic pipe sections (10) (66) onto a reel (60) including at least the steps of: (a) filling a first pipe section with a fluid (12); (b) spooling the first pipe section onto the reel; (c) filling a second pipe section with a fluid (78); (d) joining the first pipe section with the second pipe section wherein at least one of the first and second pipe sections maintains the fluid (12,78) therein; and (e) spooling the second pipe section onto the reel.

1. A method of spooling a marine pipeline comprising a plurality of bi-metallic pipe sections onto a reel, the method comprising at least the steps of:
(a) filling a first pipe section with a fluid and pressurising the fluid in the first pipe section; (b) spooling the first pipe section onto the reel; after this, (c) filling a second pipe section with the same fluid and pressurising the fluid in the second pipe section prior to joining the first and second pipe sections; after this, (d) joining the first pipe section with the second pipe section, wherein each of the first and second pipe sections maintains without relieving the pressurised fluid therein; (e) spooling the second pipe section onto the reel.
