Pipeline SCADA & RTU Systems

Pipeline SCADA must connect dispersed stations without losing clarity about command authority, communications status or alarm priority. SMEC's engineering scope can bring RTUs, metering, valves, pump/compressor stations and supervisory systems into a coherent architecture.

Remote stations — RTUs collect pipeline pressure, flow, metering, valve and equipment data at geographically distributed stations.

Supervisory layer — SCADA provides operator displays, alarms, historical trends and controlled remote commands.

Communications — Latency, outages, redundancy, time synchronisation and store-and-forward requirements shape the telemetry design.

Cyber and safety — Remote-control authority, network segregation and fail-safe local operation are essential; leak detection is a separate engineered function.

RTU/PLC panels. An RTU acquires remote station measurements and status, timestamps events and exchanges authorised commands with SCADA while preserving local control on link loss.

Remote I/O. The remote i/o is selected for the equipment, operating duty and site conditions.

Telemetry gateways. The telemetry gateways is selected for the equipment, operating duty and site conditions.

Pump and compressor interfaces. The pump and compressor interfaces is selected for the equipment, operating duty and site conditions.

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

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

Historian. The historian is selected for the equipment, operating duty and site conditions.

SCADA HMI. SCADA consolidates remote station measurements, alarms, trends and supervisory commands; local protective functions remain in field controls.

Redundant communication options. Protocols, command authority, network availability, loss-of-link response and cybersecurity boundaries must be agreed for every equipment interface.

Migrate SCADA servers and historian while retaining compatible station RTUs.

Replace ageing field RTUs in phases and add communication redundancy.

Extend pump/compressor/valve station monitoring with secure control boundaries.

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.
