Offshore Drilling Rig Electrical, Control & Safety Systems
Offshore drilling rigs contain multiple independent but interconnected electrical, control, safety and mechanical systems. Power generation and distribution, SCR/VFD drives, drilling controls, jacking systems, BOP controls, drilling monitoring, gas detection, PAGA, CCTV and auxiliary packages may come from different OEMs and different generations of technology. SMEC works at the interfaces between these systems — engineering new packages, integrating multi-OEM equipment, troubleshooting existing installations, replacing obsolete controls and preparing ageing rigs for reactivation or another drilling campaign.
Power & electrical
- Generators and generator-control interfaces
- Main/auxiliary switchboards and transformers
- SCR and VFD drive systems
- MCCs, distribution and package panels
- UPS/DC systems and battery chargers
- Power/control houses and PMS interfaces
Drilling & machinery controls
- Drilling control architecture and package interfaces
- DMS3000 drilling monitoring and operator displays
- PLC/HMI/control networks
- Jacking control and load/RPD monitoring
- Drive, brake, gearbox and machinery diagnostic interfaces where within scope
Safety & well-control interfaces
- BOP control-system interfaces
- Drilling-mud Gas Watch / gas detection
- ESD and shutdown interfaces
- PAGA and communications
- Hazardous-area CCTV/video systems
- Flare ignition systems where applicable
Modernization
Obsolete PLC/HMI replacement, legacy control migration, drive replacement, panel refurbishment, I/O migration, network/protocol conversion, documentation recovery and staged cutover.
Reactivation workflow
Installed-base assessment → obsolete/failed equipment identification → repair/replace decision → engineering → software/configuration → panel modification → FAT → mobilization → installation → SAT/commissioning.
Common questions
What scope can SMEC support for Offshore Drilling Rig Electrical & Control Systems?
SMEC can support the electrical, instrumentation, automation, control, integration, modernization, testing and commissioning elements described on this page, subject to the agreed project boundary.
Can SMEC work with an existing multi-OEM installed base?
Yes where the required technical information, access, interfaces and project approvals are available. Compatibility and scope boundaries are assessed before execution.
What information is needed to quote?
Send the asset or project, existing make/model where relevant, drawings or specification, required scope, site, required date and any shutdown or mobilization constraint.
