Title:
METHODS, APPARATUS AND SYSTEMS FOR CONVEYING FLUIDS
Document Type and Number:
WIPO Patent Application WO/2014/109839
Kind Code:
A3
Abstract:
Disclosed are pipeline systems, methods and apparatus for handling fluids in offshore oil and gas production. The systems disclosed allow subsea functional lines having diameters which differ by more than 2 standard API 5L pipeline diameters to be placed in fluid communication in such a way that the systems are piggable. Pipeline connection terminations are installed to facilitate connection of such functional lines. Such systems offer solutions to problems related to installing subsea pipeline in rough terrain, over subsea canyons and subsea scarps, installing marine risers, and long tiebacks.
