Design Ability

Equipped with solid foundations in structural design and computational analysis, the company utilizes professionalsoftware including Bflex to conduct flexible pipe cross section design, local fatigue analysis, global dynamic analysis, andjoint local strength verification. HizenFlex has ten engineers with over 10 years of experience, who possess extensive exper-tise in structural design, material selection, process design and project delivery.

Pipe Application

Subsea flexible pipes function as the critical "lifeline"connecting subsea facilities to offshore floating units. Dynamic risers represent an extremely high barrier technology, whose domestic localization poses core challenges in material strength.fatigue performance and fracture toughness. Having overcome key bottlenecks including dynamic fatigue performance andachieved successful field application, the company has secured full chain technological breakthroughs covering materialselection, structural design, fabrication and qualification testing. This makes China one of the few countries globally tomaster this technology, with key performance parameters reaching internationally advanced levels.

Research Project

HizenFlex has participated in major national science and technology special projects, including the Research on KeyTechnologies of Thermallnsulated Oil Transporting Flexible Pipes (12th & 13th Five Year Plans) and the Research on Dynam-ic Risers for 1500m Water Depth (15th Five Year Plan), and has gotten BV certification. It has successfully developed andmanufactured subsea jumpers for 2000m water depth in the South China Sea. Moreover, the company continues to inten-sify research on large dimension carcass layer forning and utra deep water joint structures for ultra deep water subseaflexible pipes, and and has accumulated valuable experience in developing acid resistant materials for full stream fluid conveyance.
