Power cable advisory and verification

Cable connections are complex to design and deliver. DNV supports technically sound decisions and clear specifications for tendering, and provides independent QA/QC reviews across project phases to help ensure technical requirements are met.

Building a new cable connection requires choices on concept, design basis, and tender requirements, followed by disciplined execution across suppliers and contractors. In large T&D projects, independent QA/QC reviews in early phases help avoid problems later and support reliability, safety, and on-time execution; during delivery, independent oversight helps assess whether technical requirements are properly realized.

About DNV’s power cable services

DNV supports the technical design and specification of cable connections (including underground to very high voltage, AC and DC), and delivers independent QA/QC and design verification across project lifecycle:

• Advisory: Delivering early-phase technical and commercial support through feasibility studies, conceptual design and design basis definition, combined with basic design and tender preparation, as well as bid evaluation and quality assurance to ensure optimal, reliable project outcomes.
• Verification: Providing independent QA/QC across the full project lifecycle—from conceptual design through commissioning—including specification reviews, supplier pre-qualification and bid evaluation, and oversight of manufacturing, installation, and commissioning as an independent guardian of delivery quality, complemented by owner’s or lender’s engineer services with structured reporting on progress, deviations, budget, and schedule.

Clear, decision-grade feasibility/design basis/specification outputs supporting tendering and execution. 
Independent verification insights (reviews, deviation reporting and recommendations) aligned to project specifications and technical risk analysis.
