Offshore Sub Agent

Balfour Beatty is currently recruiting an Offshore / Marine Agent to join our team in Avonmouth, Bristol, supporting the delivery of offshore marine construction works for the Hinkley Point C project. The Marine and Tunnelling teams at Balfour Beatty have successfully delivered two 3 km intake tunnels and a 1.5 km outfall tunnel beneath the Bristol Channel, forming a critical part of Hinkley Point C's cooling water infrastructure.

The Marine Works Team is now delivering the final phase of the programme: flooding the intake and outfall tunnels to bring the cooling water system into service and support power station commissioning. This major offshore campaign involves planning and executing the controlled flooding of the tunnels, working at the interface of marine operations, commissioning, engineering and environmental management.

• Flooding of the intake and outfall tunnels from offshore
• Removal of temporary bulkheads from offshore shafts
• Installation of permanent locking caps

Delivering these works requires significant engineering, planning and stakeholder coordination. Activities range from offshore and onshore enabling works, testing and commissioning specialist temporary works equipment through to executing the main offshore campaign in the challenging environment of the Bristol Channel, home to the world's second-highest tidal range. Success depends on effective collaboration across multiple teams to manage marine constraints, integrate commissioning requirements and ensure assets are ready for operation.

The flooding campaign represents a key milestone in transferring the intake and outfall systems into service. The project must address challenges including sediment management, water quality control, flooding sequence optimisation and long-term operational readiness, while balancing environmental, licensing and programme requirements. It offers a rare opportunity to contribute to a nationally significant infrastructure project where strategic planning, complex marine operations and innovative engineering solutions come together to deliver safe and successful commissioning.

As a Marine / Offshore Sub Agent, you will lead and coordinate a section of the offshore works, ensuring operations are delivered safely, efficiently and in accordance with programme, quality and commercial requirements. Working closely with engineering teams, subcontractors and offshore stakeholders, you will play a key role in the successful delivery of offshore construction activities.
