Foreword
GB/T 21445 "oil and gas industry design and operation of subsea production systems" is divided into nine sections.
--- Part 1. General requirements and recommendations;
--- Part 2. Flexible pipe systems for subsea and offshore;
--- Part 3. Through flowline (TFL) systems;
--- Part 4. subsea wellhead and Christmas tree equipment;
--- Part 5. subsea control umbilicals;
--- Part 6. subsea production control systems;
--- Part 7. workover/completion riser system;
--- Part 8. subsea system interface equipment ROV (ROV);
--- Part 9. Remotely operated tool (ROT) intervention system.
