Junior Heavy Lift Engineer
First seen by Alion on Oct 3, 2026.
Offshore wind is growing fast. The Netherlands is at the forefront of this transition, with ambitious targets for offshore wind capacity in the coming decade. Large-scale wind farms and next‑generation offshore grid systems require increasingly complex transport and installation solutions.
Junior Heavy Lift Engineer
Delft
Within Allseas, the Heavy Lift Engineering department plays a key role in this development. Using our unique heavy lift capabilities - including the world-leading vessel Pioneering Spirit - we install large offshore structures such as jackets, foundations and converter platforms for offshore wind projects, weighing up to 60.000 tons.
To support the growing portfolio of offshore wind installation projects, we are always open to connect with Junior Heavy Lift Engineers with a strong interest in installation engineering and the energy transition.
Your role
Playing an active role in the energy transition, you will be part of a multidisciplinary Agile team comprising creative Structural Engineers, Heavy Lift Engineers, Naval Architects and Draftsmen.
The team drives concept development and basic and detailed engineering phases for the installation of topsides and jacket structures up to 60,000 tonnes. From design and engineering, fabrication of innovative lifting tools and supports, preparation of procedures and manuals through to on-site support during yard and offshore execution, you will be involved in the entire engineering process.
- You analyse and prepare project specifications for offshore transportation and installation operations, yard preparations, load-out and barge transfer and tow operations;
- Prepare design calculations and design reports for all (structural) heavy lift design work within scope, budget and schedule;
- Develop procedures and prepare manuals for load-out, transfer, mooring, tow, installation and transportation operations;
- Interface with various disciplines (project team, vessel crew, clients, subcontractors, certification authorities, marine warranty surveyor) to define efficient and cost-effective solutions and provide ongoing engineering support;
- Come up with new solutions how Allseas can contribute to the energy transition in offshore wind;
- Stay up to date with the development of specialised equipment for installation operations;
- Perform FEED and feasibility studies to identify best solutions for single-lift installation or removal of large (> 5000 tonne) topsides and jackets;
- Prepare method and execution statements for commercial bids for new projects;
- Design lifting gear, such as spreader bars, rigging and pad eyes, internal/external lifting tools;
- Perform platform inspections at fabrication yards to confirm platform condition and feasibility of proposed installation methodology;
- Prepare factory acceptance and commissioning tests for project equipment.
