About the client
Our client is the UK engineering projects division of a major international energy company. From a landmark, modern integrated operations office in central Basingstoke - with ample parking and only a short walk from the mainline railway station - it develops projects and provides expert owner-engineering support to the group's businesses worldwide. The division is helping to lead the energy transition, combining traditional oil and gas activity with decarbonised and innovative solutions such as carbon capture and storage, hydrogen and renewables as the group moves towards a net-zero future.
Project scope
The role sits within an offshore structures discipline delivering a global portfolio of energy projects across the full life cycle - feasibility, FEED, detailed engineering and operations - on both greenfield and brownfield facilities. The discipline designs and assesses substructures and topsides for conventional energy and fast-growing energy-transition projects such as carbon capture and renewables, offering the opportunity to develop skills in new technologies on dynamic international projects.
Role overview
The Principal Engineer, Offshore Structures leads the offshore design team and provides guidance on how to execute structural analysis. The role takes a proactive approach to decision making, applies strong problem-solving skills and makes independent recommendations on solutions of varying complexity, delivering scope within schedule.
Reporting line: Leads a team of structural engineers and designers; interfaces with other discipline PDLs, planners and project management, and works within the discipline framework for the assigned project.
