| Summary | This standard specifies the recommended practices for the design, manufacture and use of underwater emergency well-sealing devices. This standard is applicable to the manufacture of new underwater sealing equipment components and the improvement of the original underwater sealing equipment. This standard helps to form the design basis, storage, transportation, maintenance, test documentation and operational instructions. This standard does not provide procedures or equipment for a flow control system that may be connected to an underwater emergency well-sealing device. All equipment and operations downstream of the subsea well-sealing device are considered part of the flow control system and are outside the scope of this standard. |
