We provide comprehensive Electrical Engineering Design services for greenfield, brownfield, and revamp projects across Oil & Gas, Petrochemical, Power, and Industrial facilities. Our electrical designs focus on safety, reliability, compliance, and constructability, in accordance with IEC, IEEE, NFPA, API, IS, and project-specific standards.
Electrical Design Basis
Preparation of the Electrical Design Basis document defining system philosophy, power distribution levels, redundancy, protection schemes, hazardous area requirements, earthing philosophy, lighting philosophy, and applicable international codes and standards. This document governs all electrical engineering deliverables.
Electrical Site Survey / Verification Report
Detailed site surveys and as-built verification of existing electrical systems including substations, MCCs, panels, cabling, earthing, and lighting. Issuance of verification and gap analysis reports to support brownfield modifications and safe execution of revamp projects.
Electrical Load List
Development of electrical load lists covering normal, emergency, and critical loads. Includes connected load, operating load, demand factors, diversity, and future spare capacity for accurate system sizing.
Power System Studies
Engineering studies to ensure safe and reliable operation of electrical systems, including:
- Load Flow Analysis
- Short Circuit Study
- Motor Starting Study
- Protective Device Coordination Study
- Arc Flash Study
Single Line Diagrams (SLD)
Preparation and updating of Single Line Diagrams for HV, MV, and LV systems, showing power sources, transformers, generators, switchgear, protection devices, metering, and system interconnections.
Substation & Electrical Room Layouts
Design of substation and electrical room layouts, including equipment arrangement, access clearances, cable trenches, ventilation, fire protection interfaces, and maintenance considerations.
MCC & Switchgear Design
Engineering design for Motor Control Centers (MCCs) and switchgear, including feeder sizing, starter selection, protection philosophy, control interfaces, and panel layouts.
Panel GA & Internal Layout Drawings
Preparation of General Arrangement (GA) and internal layout drawings for electrical panels, including component arrangement, wiring ducts, terminal blocks, and heat dissipation considerations.
Cable Sizing & Voltage Drop Calculations
Electrical calculations for power and control cable sizing, including voltage drop, short circuit withstand, derating factors, and installation conditions.
Cable Schedule
Preparation of electrical cable schedules detailing cable type, size, voltage rating, routing, length, termination points, and segregation requirements.
Cable Drum Schedule
Development of cable drum schedules to support procurement, transportation, and site installation planning.
Cable Routing Layouts
- Overall Electrical Cable Routing Layout
- Unit-wise Cable Routing Layout
- Area-specific Cable Routing Layouts
These layouts define tray routing, trench routing, segregation between power, control, and instrumentation cables, and interface with other disciplines.
Earthing & Lightning Protection System
Design of earthing and grounding systems, including equipment earthing, personnel safety, earth grid layouts, earth resistance calculations, and bonding details.
Design of lightning protection systems as per IEC and NFPA standards.
Lighting System Design
Engineering of normal, emergency, and escape lighting systems, including lighting calculations, fixture selection, illumination levels, and lighting layouts for indoor and outdoor areas.
Emergency & UPS Power Systems
Design of UPS, battery, and emergency power systems, including load sizing, autonomy calculations, distribution philosophy, and integration with critical systems.
Electrical Hook-Up Drawings
Preparation of electrical hook-up drawings for motors, heaters, panels, lighting fixtures, and field equipment, including power supply, control wiring, earthing, and termination details.
Wiring Diagrams
Development of wiring diagrams for panels, MCCs, switchgear, and field devices, supporting accurate installation and troubleshooting.
Cable Block Diagrams
High-level cable block diagrams showing electrical power distribution from sources to end users, simplifying system understanding.
MCB & Distribution Board Layouts
Design of MCB, DB, and distribution layouts, including load segregation, protection coordination, and spare capacity provisions.
Electrical Bulk MTO
Preparation of Bulk Material Take-Offs (MTO) covering cables, trays, panels, lighting fixtures, earthing materials, and accessories for procurement and cost estimation.
Inspection & Test Documentation
Preparation of ITRs, test procedures, and checklists for electrical installation, testing, pre-commissioning, and commissioning activities.
