Onshore Offshore Client Representative (OCR)

Route Preparation – Pre-Lay Rock Berm Operations France–Spain HVDC Interconnection (Biscay Gulf)

Project Company: INELFE Main Contractors: NKT (Link 1), Prysmian PowerLink (Link 2) Vessel: Tjalfe R – Rohde Nielsen (Split Hopper Barge) Mobilisation: April 2026 Duration (indicative): ~1 day mobilisation + ~6 days offshore rock dumping (excluding standby)

1. Role Overview

INELFE is seeking one (1) Onshore Offshore Client Representative (OCR) to supervise and control the pre-lay rock berm installation activities executed offshore as part of the Biscay Gulf HVDC interconnection project.

Although defined as an Offshore Client Representative, the position is primarily onshore-based, located near the harbour, with potential onboard visits if required for HSE or technical verification.

The OCR represents INELFE’s interests and ensures that route preparation works are executed:

  • In accordance with contract and technical specifications

  • In compliance with marine and HSE regulations

  • In line with schedule and quality requirements

The OCR has the authority to escalate non-compliance and stop works if required.

2. Project Context

The Biscay Gulf interconnection will connect:

  • 400 kV Cubnezais substation (France)

  • 400 kV Gatika substation (Spain)

Through:

  • 275 km of submarine HVDC cables

  • ~120 km of underground HVDC cables

  • Two bipoles (2 × 1,000 MW)

  • Four landfalls (France and Spain)

Where seabed conditions prevent burial, rock placement is required to ensure adequate mechanical protection and cable stability.

The current scope concerns pre-lay rock berm dumping to create a berm ramp (approx. 25 m long × 8 m height profile) enabling future cable installation.

3. Scope of Works – Route Preparation

The OCR will oversee:
