Project Engineer Decommissioning - Medior/Senior

Join Allseas in Shaping the Future of Offshore Decommissioning

The North Sea is entering a new phase. With over 470 oil and gas platforms scheduled for removal in the next few decades, decommissioning is one of the most complex and critical challenges in the offshore industry today.

At Allseas, we are uniquely positioned to lead this effort. Our record-breaking vessel, Pioneering Spirit, is capable of lifting and removing entire topsides and jackets in a single lift — dramatically reducing offshore risk, time, and cost. With a full pipeline of North Sea removals ahead, we are expanding our Heavy Lift Engineering team and looking for a Project Engineer who thrives on precision, complexity, and cutting-edge engineering.

This role is fully dedicated to some of the most ambitious lift projects ever undertaken.

Your role

As Project Engineer, you’ll join a multi-disciplinary Agile team of Structural Engineers, Heavy Lift Engineers, Naval Architects, and Draftsmen. This team is responsible for developing and delivering all engineering for the removal of offshore platforms weighing up to 60,000 tonnes. You will keep the overview from early concept and design, through detailed engineering and tool development, to onshore preparation and offshore execution support.

What You will do:

• Define project goals and translate them into actionable engineering plans
• Coordinate with internal disciplines, clients, subcontractors, and project managers
• Maintain and prioritise the team’s engineering backlog and deliverables
• Track progress and lead the team in making informed, timely decisions
• Review and approve engineering output, ensuring readiness for offshore execution
• Represent and inspire your team, promoting a culture of ownership and accountability
• Drive collaboration and transparency to maximise project value

What we expect from you

In order to be successful in this role you should recognize yourself in most of the following criteria:

• A BSc or MSc in Mechanical, Civil, Aerospace, or Maritime Engineering

• At least 5 years of hands-on engineering experience in offshore construction, decommissioning, or heavy marine operations

• Preferably, you were already involved in platform removal, jacket/topside lifting, or large-structure offshore handling — from engineering to execution

• Strong affinity with engineering drawings, lift plans, procedures, and equipment design (e.g. lifting frames, seafastening structures)

• Comfortable leading a small team of specialists and interfacing with fabrication yards, offshore crews, and subcontractors

• Experience with engineering software such as Autodesk Inventor, ANSYS, Orcaflex, or SACS is a plus

• Willingness to work offshore during critical project phases

• A clear communicator who can bridge technical and operational discussions with ease

• Strong planning and organisational skills, with a safety-first and results-oriented mindset

What we offer

Allseas offers you the chance to work on high-profile, large-scale decommissioning projects alongside a world-class engineering team. Our culture is dynamic, innovative, and built on trust, ownership, and real responsibility.

You can expect:

• Competitive salary and top-tier pension scheme
• Performance-based raises and annual bonus
• 30 vacation days + flexible working hours
• Extensive learning opportunities and personal development budget
• Company-sponsored fitness plan and mental well-being support
• Regular team events, sports groups, and a strong internal community
