Water Uptake Riser

Water Uptake RiserOil States Merlin® connection is, for the first time, being used to assist in FLNG installations utilizing our water uptake riser. Our connections offer a long conduit to provide cooler water from deeper depths for FLNG processing, allowing smaller, more efficient topside facilities. Current designs are based on our Merlin® tendon tether connection, which has been used for tethering TLP platforms to the seabed for the last 25 years and can be geometrically sized specifically for the project. Oil States offers the complete package, Merlin connections welded to pipe and spacers  per client request.
