API 17J & API 15S Aligned Systems
Shallow-Water Offshore Flowlines & Jumpers
Shallow-water offshore flowlines and subsea jumpers engineered for reliable pipeline performance in dynamic marine environments. Reinforced thermoplastic pipe (RTP) and fully bonded thermoplastic composite pipe (TCP) systems provide corrosion-resistant offshore pipelines designed for rapid installation, long service life, and dependable performance in water depths up to 150 m and pipe sizes up to 10".
Performance
Characteristics
