Offshore Senior Project Engineer

Balfour Beatty is currently recruiting an Offshore Senior Project Engineer 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.

Key scope includes:

• 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 an Offshore Senior Project Engineer, you will lead and coordinate sections of the offshore marine works, ensuring activities are delivered safely, efficiently and in accordance with programme, quality and commercial requirements. You will manage engineering and supervisory teams, work closely with subcontractors and key stakeholders, and play a vital role in the successful delivery of one of the UK's most significant infrastructure projects.

Key Duties:

• Lead and manage a section of offshore works, ensuring safe and efficient delivery.
• Manage Sub Agents, Section Engineers, Site Engineers, and subcontractors involved in offshore operations.
• Review and improve method statements, risk assessments and safe systems of work.
• Ensure the effective implementation of permits, temporary works requirements and construction controls.
• Monitor progress against programme and identify opportunities to improve productivity and performance.
• Produce and manage detailed construction programmes and resource plans.
• Oversee quality management processes including inspections, audits, handover documentation and non-conformance management.
• Liaise with designers, project teams and subcontractors to resolve technical issues.
• Monitor section budgets, costs and commercial performance.
• Support procurement activities and management of subcontract packages.
• Maintain project records and prepare reports for the wider project team and client.
