API SPEC 16D KAZAKH-2004 Specification for Control Systems for Drilling Well Control Equipment and Control Systems for Diverter Equipment (SECOND EDITION)
GENERAL These specifications establish design standards for systems, that are used to control blowout preventers (BOPs) and associated valves that control well pressure during drilling operations. The design standards applicable to subsystems and components do not include material selection and manufacturing process details but may serve as an aid to purchasing. Although diverters are not considered well control devices, their controls are often incorporated as part of the BOP control system. Thus, control systems for diverter equipment are included herein. Control systems for drilling well control equipment typically employ stored energy in the form of pre
