DNV's scope at UK's first offshore CCS project expands with independent certifier role
What happened
DNV was selected as the independent certifier for the Northern Endurance Partnership (NEP) UK carbon‑capture and storage project, covering the full CO2 transport chain from compression through the offshore pipeline. The role is now a regulatory expectation and will require documented QA/QC, inspection records and commissioning evidence ahead of the handover gate. Buyers should watch how certifier timelines are scheduled into payment and acceptance milestones
Buyer takeaway
Treat independent certification as scheduled, billable scope and include certifier milestones and evidence responsibilities in supplier SOWs
Cost / money
Certification will add QA/QC and inspection cost lines and can create rework budgets if suppliers fail initial evidence checks
Supplier / commercial
Suppliers will need to produce traceable test evidence and may price subcontracted inspection services; expect negotiation over who bears certifier‑driven rework costs
Safety / operations
Independent certifier status raises the likelihood that missing records will trigger stop‑work or remedial scopes during commissioning
What to watch
Watch whether owners place certifier deliverables into payment milestones or allow suppliers to invoice for certifier‑mandated testing and rework
Key facts
- Covers the full CO2 transport chain from compression to 145km offshore pipeline
- Appointed to verify design integrity, construction quality and commissioning readiness
- Certification acts as the formal gate before CO2 storage operations begin

The independent certifier function is a new regulatory requirement for the UK’s CCS sector, providing objective, evidence‑based assurance that nationally significant CO2 transport and storage infrastructure meets its license obligations before entering operation, DNV said
The certification process will establish the documented evidence required to demonstrate compliance and support a safe transition from construction to operation, the company said. “Independent certification provides regulators and project partners with confidence that complex CO2 transport infrastructure has been delivered in accordance with its licence requirements,” said Hari Vamadevan, Senior Vice President and Regional Director for the UK & Ireland, Energy Systems at DNV
