NorNed (NL-NO), BritNed (NL-UK), COBRAcable (NL-DK) — TenneT NL-side anchor.
Cross-border converter-station workforce mobilisation against TenneT NL-administered HVDC links — NorNed (700 MW), BritNed (1,000 MW), COBRAcable (700 MW ±320 kV) — IEC 61936, NEN-EN 50110, NEN 3140 / NEN 3840.

Topology decides the IEC stack.
NorNed (NL-NO), BritNed (NL-UK) and COBRAcable (NL-DK) each dock against a different IEC stack. NL-side converter stations operate under TenneT contractor framework + NEN-EN 50110 + NEN 3840 (HV) + NEN 3140 (LV adjuncts).

Named projects in this jurisdiction
- NorNed NL-NO (580 km, 700 MW, since 2008) TenneT + Statnett
- BritNed NL-UK (260 km, 1,000 MW, Maasvlakte ↔ Isle of Grain, since 2011) BritNed Development Ltd (National Grid + TenneT JV)

TenneT NL-side operates three HVDC interconnectors. NorNed (NL-NO) was the world’s longest HVDC subsea at commissioning in 2008; BritNed (NL-UK) came in 2011; COBRAcable (NL-DK) at ±320 kV VSC commissioned September 2019.
01. Pre-pricing — CAO Metalektro + CAO Bouw split
Converter-station workforce is principally electrical, so CAO Metalektro carries the wage floor on the energised work; the TenneT HSE Passport is the operational authorisation gate. Civil-shell scope on the converter-hall sits under CAO Bouw & Infra 2025-2027 with BPF Bouw 25.73% pension premium.
02. MeldNL + A1 + TenneT HSE Passport
A1 + MeldNL filing + TenneT HSE Passport registration predate site arrival. The HSE Passport is non-portable across TenneT vs other-TSO assets — a worker authorised on COBRAcable substations needs separate registration for BritNed substations.
03. BPF Bouw + CAO Metalektro onboarding
Civil-trade portion at BPF Bouw 25.73%. Energised-work portion enrols against CAO Metalektro.
04. NLA-defensible evidence pack
Standard WagwEU + Wtta-phasing profile plus TenneT-specific competency-register reconciliation. Minimum survivable pack: SEPA-traceable remuneration, CAO-compliant timesheets, MeldNL submission, NEN 3840 / NEN 3140 aanwijzing, TenneT HSE Passport record.
05. India and Gulf sourcing corridors — the EFK-equivalent pathway
Indian electrical-trade pool delivers IIW-certified high-voltage fitters + BHEL-trained substation commissioners. Anerkenning van Beroepskwalificaties recognition + TenneT HSE Passport scheduled into post-arrival 2-4 week window.
The 8 to 14-week corridor delivers the NEN-3840-eligible candidate against NorNed, BritNed or COBRAcable.
