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.\nKey scope includes:\nFlooding of the intake and outfall tunnels from offshore\nRemoval of temporary bulkheads from offshore shafts\nInstallation of permanent locking caps\nDelivering 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.\nThe 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.\nAs a Marine / Offshore Section Engineer, 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.\nWhat you'll be doing\nAs a Section Engineer, you will support the planning, coordination and delivery of offshore and marine construction activities, ensuring works are completed safely, efficiently and in accordance with project requirements. You will provide technical leadership within your area of responsibility, working collaboratively with the client, suppliers, subcontractors and wider project team to resolve engineering challenges and maintain programme delivery.\nKey Duties:\nActing as the technical interface between the project team, client, suppliers and subcontractors.\nReviewing permanent and temporary works designs to ensure safe and practical construction solutions.\nPreparing and reviewing Method Statements, Risk Assessments, Inspection and Test Plans (ITPs) and other construction documentation.\nPlanning and coordinating marine and offshore construction activities to support programme delivery.\nRaising and managing Technical Queries (TQs/RFIs) and supporting the resolution of engineering and construction issues.\nProducing supplier instructions and monitoring progress to ensure timely implementation of works.\nMaintaining quality records and supporting the production of handover documentation.\nPromoting high standards of safety, quality and environmental performance across all site activities.\nSupporting audits, inspections and assurance activities, whilst mentoring and developing less experienced engineers.\nIdentifying construction risks and opportunities, implementing practical solutions to support safe and efficient project delivery\nWho we're looking for\nWe are seeking an experienced offshore professional with a good understanding of marine construction activities, safety leadership and operational delivery.\nKey skills required:\nExperience working within offshore construction, marine operations or major infrastructure projects.\nReview designs of permanent and temporary works.\nReview and assist in the development of Sub-Contractor Method Statements and Risk Assessments for offshore works.\nRelevant Engineering Degree (Civils, Mechanical or Coastal)\nUnderstands Permit System and actively raises Permits to Work.\nIs able to identify potential hazards and is proactive in implementing actions and controls.\nGood level of Environmental Awareness.\nAble to resolve issues with control and information provided.\nAble to identify issues on drawings and suggest construction solutions.\nActively drives the production of quality ITP and handover documentation and information.\nAwareness of specification and other Contract documents.\nUnderstands and can use the information provided in the Stage Programme, disseminating this to the team.\nWhy work for us\nOur teams at Balfour Beatty deliver some of the UK's most ambitious, exciting and technically challenging infrastructure projects.\nHinkley Point C is one of Europe's largest construction projects and offers a rare opportunity to work at the forefront of marine construction and offshore engineering. You will gain experience on complex offshore operations while working alongside industry-leading specialists and project teams.\nAt Balfour Beatty, we are committed to safety, innovation, sustainability and professional development.
