PhD Stipend in Advanced Design and Manufacturing Technologies for Subsea Offshore Renewable Infrastructure Applications

The Department of Energy at Aalborg University (AAU Energy) invites applications for a PhD position within the project HVDC Subsea Electrode Unit starting from May 2026 or soon hereafter. The 3-year employment is funded by the Energy Technology Development and Demonstration Programme (EUDP) and aims to deliver a standardised robust and scalable subsea electrode unit for HVDC systems.

The PhD project will develop a methodological framework for reliability-based structural design and integrity management of the support structure of the subsea HVDC electrode unit supported by experimental tests and validated numerical models to enable lightweight reliable cost-efficient and sustainable novel design concepts. The PhD will also explore additively manufactured (AM) concepts with strong fatigue corrosion and biofouling resistance. Join this exciting academiaindustry collaboration advancing next-generation HVDC subsea infrastructure and be part of a supportive international research environment working closely with academic and industrial partners as you develop into a recognised independent researcher.

Project context and key objectives
As offshore wind deployment expands farther from shore HVDC transmission is increasingly used for efficient long-distance power transfer where offshore corrective operations can be costly and logistically demanding. HVDC subsea electrode solutions can support affordable reliable and sustainable transmission by enabling installation directly on the seabed and reducing the need for additional protective barrier structures and associated costly vessel operations.
However safe cost-efficient and sustainable deployment requires life-cycle management strategies that account for environmental loading soilstructure interaction material behaviour prominent degradation and failure mechanisms and associated uncertainties.

Your work tasks
The PhD student will develop their own research track within the project whilst supported by close supervision by AAUs leading academics and access to AAU Energys experimental and numerical modelling capabilities. The position is offered in the research group Offshore Renewable Energy Systems and the PhD student will be positioned at the Esbjerg section of AAU Energy. Expected activities include (but are not limited to):

• Gain in-depth understanding of the loads material behaviour and failure mechanisms (ultimate strength fatigue corrosion and biofouling ) of subsea structures.
• Derive limit state functions associated with the failure mechanisms using high-fidelity Finite
  Element Analysis.
• Perform sensitivity and uncertainty analysis to uncover the most significant variables in the derived limit states.
• Develop a reliability-based structural design framework for the support structure involving target reliability levels and partial safety factors.
• Establish a risk-based structural integrity management framework offering optimal inspection and maintenance decision support.
• Explore additively manufactured structural concepts including performance trade-offs for
  lightweight fatigue- and corrosion-resistant solutions.
• Publish results in peer-reviewed journals and present at conferences; contribute to technical
  reports and collaborate with industrial partners.

Your competencies

We are seeking candidates who possess or are about to complete a Masters degree in Mechanical Structural Civil Materials or Ocean engineering or a closely related discipline. A strong background and demonstrable interest in structural mechanics as well as engineering modelling analysis and simulation is essential. Further the ideal applicant will be capable of working independently efficiently managing their own workload and collaborating productively within a multidisciplinary team environment. As English is the working language excellent communication skills are required for technical reporting producing publications and delivering presentations.
In addition it would be advantageous for applicants to demonstrate proficiency in at least one scientific programming environment such as Python MATLAB or R. Familiarity with structural degradation phenomenaincluding fatigue corrosion and biofoulingwould also be beneficial. Experience working with Finite Element Method (FEM) tools such as Abaqus ANSYS OrcaFlex or similar software is highly regarded. Furthermore an interest or practical experience in additive manufacturing including design materials and processes or testing would strengthen your application. Finally a background or keen interest in statistics statistical analysis and surrogate-based modelling would be considered an asset.

Qualification requirements
PhD stipends are allocated to individuals who hold a Masters degree. PhD stipends are normally for a period of 3 years. It is a prerequisite for allocation of the stipend that the candidate will be enrolled as a PhD student at the Doctoral School of Engineering and Science in accordance with the regulations of Ministerial Order No. 1124 of September 19 2025 on the PhD Programme at the Universities and Certain Higher Artistic Educational Institutions. According to the Ministerial Order the progress of the PhD student shall be assessed at regular points in time. As part of the PhD study you are among other things required to complete PhD courses corresponding to 30 ECTS gain experience with teaching or other forms of knowledge dissemination and complete an external research stay outside of Aalborg University preferably 3-6 months at a foreign research institution.
