BOP Control System

BOP control is a safety-critical function. SMEC's engineering discussion should begin with the existing BOP equipment, applicable well-control requirements, control philosophy and test evidence—not generic claims of faster response or guaranteed safety.

Engineering, interface definition, panel/package build, software/configuration where applicable, FAT, site installation support, SAT/commissioning and lifecycle support.

Well-control interface — The BOP control package operates defined well-control functions through approved hydraulic/pneumatic and electrical interfaces.

Control stations — Local/remote stations, selector logic, status indication and diagnostics are mapped to the BOP OEM and well-control specification.

Redundancy and testing — Accumulator capacity, fail-safe behavior, testing and independent verification are safety-critical and cannot be assumed from PLC hardware alone.

Scope boundary — Control-panel modernisation must be distinguished from supply or recertification of the mechanical BOP stack.

Local and remote control panels. Panel layout, ingress protection, segregation, component selection and service clearance follow the installation environment, load schedule and maintenance requirements.

Hydraulic/pneumatic interfaces as specified. Hydraulic pressure, accumulator capacity, valve logic and instrument feedback must be checked against the equipment OEM documentation and approved safety functions.

Valve status feedback. Valve actuation and position feedback must follow the approved process control and fail-safe philosophy, including loss-of-power behaviour.

Pressure monitoring. The pressure monitoring is selected for the equipment, operating duty and site conditions.

Alarms. Alarm thresholds, priorities, delays and operator actions must be documented to avoid nuisance alarms and missed critical events.

Redundancy interfaces. The redundancy interfaces is selected for the equipment, operating duty and site conditions.

Event recording. The event recording is selected for the equipment, operating duty and site conditions.

Equipment diagnostics. The equipment diagnostics is selected for the equipment, operating duty and site conditions.

Replace obsolete panel indication or approved interface components under well-control change management.

Improve alarm/event traceability where permitted by OEM and well-control specification.

Renew cabling, connectors or instrumentation with documented testing and approvals.

Retrofit scope depends on existing OEM interfaces, component condition, available space, shutdown windows and the approval basis of any safety-related functions.

Relevant IEC, ISO, API, classification-society, hazardous-area or functional-safety requirements must be selected according to the specific system and installation. Where applicable, the project package may include electrical drawings, GA layouts, datasheets, I/O schedules, cause-and-effect, communication lists, inspection records, FAT/SAT procedures, calibration records and as-built documents. No unverified compliance certification is claimed here.
