SY/T 5053.2-2020 in English

Scope

This standard specifies the minimum design standards for wellhead control equipment and diverter control systems used to control blowout preventers (BOPs) and during drilling. This standard applies to the following control system categories: a) Controls for surface and surface BOP groups; b) Separate hydraulic control systems for subsea BOP groups; c) Electro-hydraulic/MUX control systems for subsea BOP groups; d) Emergency control systems for subsea BOP groups; e) Backup control systems for subsea BOP groups; f) Control systems for diverters. This standard applies to control system design, manufacture and testing, and does not include the selection of raw materials and manufacturing process requirements, which can be used as technical requirements for procurement. Diverters are not drilling equipment but are used as part of the BOP control system. Therefore, diverter control systems are also included in this standard.
