About the job

For a position as a PhD Candidate, the goal is a completed doctoral education up to an obtained doctoral degree.

HyLINE II project:

The subsea pipeline network on the Norwegian Continental Shelf (NCS) is increasingly being recognized as an opportunity for the large-scale transport of hydrogen from Norway to Europe. Utilizing existing natural gas pipelines for transportation of hydrogen gas brings several challenges, especially the risk of hydrogen embrittlement. Ensuring the safety of hydrogen transport relies on understanding its impact on pipeline materials. Recent findings from the RCN project HyLINE (2019-2023) highlight that while hydrogen adversely affects the mechanical properties of investigated pipeline steels, they may still meet existing design standards. However, the heat-affected zone of welds appears to be more vulnerable. To address this gap, HyLINE II will focus on the material integrity of welded joints in subsea hydrogen pipelines, examining their impact on overall pipeline integrity.

PhD project:

Your research is expected to cover experiments, theoretical work, and partial numerical simulation. Main focus will be placed on the material characterization of pipeline steels (base material and weldment) in presence of Hydrogen gas post-mortem analysis of tested specimens for understanding the failure mechanisms. Your research will also support establishment and modification of innovative experimental approaches for characterization of fatigue/fracture-hydrogen interaction in pipeline steel alloys of the project.

Your role will provide ample opportunities to interact and collaborate with fellow technologists and scientists within mechanical engineering and material science.

This position is financed by the Research Council of Norway’s Knowledge-building Project for Industry, on Safety and Integrity of Hydrogen Transport Pipelines (HyLINE II ) in a collaboration between SINTEF, NTNU, Kyushu University and industrial partners Equinor, Gassco, Total E&P, TechnipFMC, Tenaris and Shell.

Your immediate leader is Associate Professor Nima Razavi.

Duties of the position

• performing mechanical characterization (such as tensile, fracture and fatigue tests)
• microstructural analysis of the pipeline alloys used in the project
• application of advanced damage detection methods for structural integrity assessment
• application and development of local approaches for fatigue life prediction
• write and defend a PhD thesis
• take part in the mandatory PhD research education programme

Required selection criteria

• you must have a professionally relevant background in mechanical engineering or material science
• your education must correspond to a five-year Norwegian degree program, where 120 credits are obtained at master's level
• you must have a strong academic background from your previous studies and an average grade from the master's degree program, or equivalent education, which is equal to B or better compared with NTNU's grading scale. If you do not have letter grades from previous studies, you must have an equally good academic basis. If you have a weaker grade background, you may be assessed if you can document that you are particularly suitable for a PhD education.
• you must meet the requirements for admission to the faculty's doctoral program
• excellent written and oral English skills
• documented strong background in experimental mechanics, solid mechanics and mechanics of materials
• documented excellent track record of academic achievement

The appointment is to be made in accordance with Regulations on terms of employment for positions such as postdoctoral fellow, Phd candidate, research assistant and specialist candidate  and Regulations concerning the degrees of Philosophiae Doctor (PhD) and Philosodophiae Doctor (PhD) in artistic research national guidelines for appointment as PhD, post doctor and research assistant 

Preferred selection criteria

•  knowledge and experience in mechanical testing of materials or components
• good understanding in fatigue and fracture mechanics
• knowledge of metallography and material science would be given additional credit in evaluation
• experience in using Finite Element Codes such as ABAQUS, ANSYS, etc. for numerical analysis
• ability to conduct high quality research and publish results in acknowledged peer-reviewed conferences and journals

Personal characteristics

• motivated, independent and enthusiastic
• ability to systematically carry out goal-oriented work
• enjoy interdisciplinary research
• interest in learning and working in teams
• skills to deliver oral and written presentation of research results
• interest in conducting experimental and numerical research

Emphasis will be placed on personal and interpersonal qualities.

We offer

• exciting and stimulating tasks in a strong international academic environment
• an open and inclusive work environment  with dedicated colleagues
• favourable terms in the Norwegian Public Service Pension Fund
• employee benefits

Salary and conditions

As a PhD candidate (code 1017) you are normally paid from gross NOK 532 200 per annum before tax, depending on qualifications and seniority. From the salary, 2% is deducted as a contribution to the Norwegian Public Service Pension Fund.

The period of employment is 3 years.

Appointment to a PhD position requires that you are admitted to the PhD programme in Engineering  within three months of employment, and that you participate in an organized PhD programme during the employment period.

--------------------------------

The position is subject to external funding.

It is a prerequisite you can be present at and accessible to the institution daily.

About the application

The application and supporting documentation to be used as the basis for the assessment must be in English.
