... Abstract Pipeline design for high pressure/high temperature applications (HPHT) requires the use of heavy walled pipe up to 2" thickness. This leads to enhanced pipe chemistry & complexity for girth weld fabrication, particularly when sour service requirements are specified. Subsea 7...

...-level trust between LLOG and Subsea 7. The project shifted from a plan to install the entire pipeline, In-Line Sled (ILS) and Pipeline End Termination (PLET) in a single trip to using multiple assets and mobilisations. The asset changes were required to maintain LLOG's first oil requirements and meant...
