Through our game-changing solutions for complex energy, urban, nuclear and water projects, we help our clients create a positive impact towards a sustainable world, where people, planet and profit collectively thrive.   


As Mechanical Systems Engineer in Offshore Energy, you will focus on the mechanical and low voltage equipment and systems included in offshore energy platforms (e.g. drainage, fuel, water, sewage, HVAC, Fire fighting, etc.). The integration of all systems in the design within the set space boundaries is a true challenge for you. You will liaise with project engineers, project manager, engineering partners, manage engineering subcontractors and maintain contact with the client and suppliers. The projects you will be working on include international Owner’s Engineer or EPC Engineer missions during the development and costructions phase, typically offshore wind projects above 200 MW and associated HVAC/HVDC/H2 or other conversion platforms, energy islands, etc. These projects are typically executed for less experienced clients or in emerging sectors or countries (e.g. Taiwan, Vietnam, Italy) but also in the more established markets like NL, GE, UK, FR, BE, etc.) and are typically staffed with international teams. 

You will be responsible for:  

  • Execute engineering in 4 phases: concept design, basic engineering, detailed engineering and production support 
  • Elaboration of functional descriptions and technical requirements for systems and equipment. 
  • Participate in the procurement of system suppliers.  
  • Follow-up system supply, installation and commissioning regarding budget, planning, interfaces, validation of variation orders, document control, etc. 
  • Prepare technical space layouts, system diagrams, outfitting arrangements 
  • Participate in interfacing and system integration with other disciplines and co-makers 
  • Ensure good communication in the project: with the client, team members, vendors/partners, lender’s engineer, Management; arrange/participate in project meetings; 
  • Ensure that all project and corporate procedures are correctly followed, especially regarding HSE; 
  • Ensure that knowledge within his/her fields of expertise is capitalized upon. 
  • Contribute to the satisfaction of the client 
  • Look for continuous improvement in all processes and methodologies. 
  • Actively take part in innovative projects such as floating offshore projects, hybrid renewable projects including offshore energy.
