The Aptara flexible pipes were developed to serve the deepwater and ultra-deepwater applications in water depths to 3,000 meters, cost-effectively.
The latest composite component we use for our risers is a pressure armor layer, made up of carbon-fiber reinforced thermoplastic tape, driving weight down by 30% over conventional flexible pipe without affecting bending radius or compressive load capability.
Its benefits involve the ability to use free-hanging catenary configuration in up to 3,000 m water depth — eliminating the need for buoyancy elements, reducing the length of risers and making for simpler and more economic installation. An additional advantage is a reduced CO2 and H2S permeated gas flow rate through the assembly, giving further operational and cost benefits.
