ELECTRICAL DESIGN ENGR- UG CABLE PROJECT Saudi Services for Electro Mechanical Works Co.

A. Job Purpose: To design, analyze, and develop high-performance underground power transmission systems (typically 110 kV to 380 kV and above), ensuring reliability, safety, and compliance with international standards and utility specifications. B. Key Responsibilities: 1. Design & Engineering • Prepare detailed electrical designs for EHV/HV underground cable systems, including: • Cable route selection and optimization • Cable sizing and rating calculations (ampacity, voltage drop, short-circuit ratings) • Thermal analysis and soil resistivity studies • Shielding, earthing, and bonding system design • Reactive compensation and sheath voltage calculations • Develop single-line diagrams (SLDs), layout drawings, and schematic diagrams. • Prepare cable cutting lengths. • Prepare cable pulling calculations and installation method statements. • Select appropriate cable types, joints, terminations, link boxes, and accessories. 2. Technical Studies • Perform electrical system studies, such as: • Load flow, short-circuit, and protection coordination • Transient and steady-state sheath voltage studies • Insulation coordination and induced voltage analysis • Thermal and electromagnetic field (EMF) analysis • Evaluate and optimize cable system reliability and losses. 3. Standards & Compliance • Ensure all designs comply with IEC, IEEE, CIGRÉ, BS, and local utility standards. • Review vendor drawings and technical documents to verify compliance with project requirements. • Prepare and review technical specifications, data sheets, and tender documents. 4. Project Management & Coordination • Coordinate with civil, mechanical, and telecommunication teams on trench design, ducts, and interfaces. • Support procurement, construction, and commissioning teams with technical guidance. • Participate in factory acceptance tests (FATs) and site acceptance tests (SATs). • Provide as-built documentation and technical support during project handover. • Ensure designs meet safety, environmental, and operational reliability standards. • Identify and mitigate design-related risks early in the project lifecycle. • Participate in design reviews and HIRA (Hazard Identification and Risk Assessment) activities. • Quality, Safety & Risk Management
