NTNU - knowledge for a better world
The Norwegian University of Science and Technology (NTNU) creates knowledge for a better world and solutions that can change everyday life.
Faculty of Engineering
Department of Marine Technology
Phd position within Marine Structures
PhD position within Marine Structures (IV-227/18)
A PhD position is available at the Department of Marine Technology, NTNU within the area of mooring system design and operation. This position is a part of the KPN project LIFEMOOR, which is supported by the Research Council of Norway as well as the industry.
The aim of LIFEMOOR is to close this gap in knowledge and develop the tools needed for reducing the probability of chain failures and enable safe and cost-effective lifetime extension of existing mooring lines. The project will develop the fundamental knowledge on how the main degradation mechanisms in a chain (corrosion and wear) affect fatigue crack initiation and propagation in chains. This knowledge will be applied in development of inspection methods and monitoring systems that can be used as input to degradation and fatigue life predictions in a quantitative way.
The acquired knowledge forms the basis for application of probabilistic methods, where global loads and metocean data can be used in design, operation and lifetime extension. Offshore oil and gas is the primary focus in the project, although the developed framework will be relevant for operation, design and lifetime extension of all floating installations, such as offshore wind turbines and fish farms.
The present Phd research aims to develop a methodology for estimation of reliability and failure probability. The degree of uncertainties related to monitoring systems, computed fatigue load effects, degradation levels and fatigue capacity are to be quantified. Corresponding probabilistic models of load effect and capacity as a function of time are also established, which allows the corresponding failure probability to be estimated.
As inspection results represents events which occur at specific time intervals, methods for updating the probability distributions and failure probabilities are required. Bayesian methods provide a versatile tool for this purpose. Having computed the failure probability as a function of time, this can be compared to target levels which are implied by the relevant existing design guidelines and codes. By identifying the times at which the target levels are exceeded, proper decisions can be made with respect to inspection, replacement and decommissioning.
The position requires a Master’s degree in marine technology, ocean engineering or a similar relevant area. Disciplines such as structural analysis and hydrodynamics are particularly relevant, preferably with some experience regarding probabilistic modelling. Research or engineering experience in relation to mooring systems is also considered to be an advantage.
'Excellent English skills, spoken and written, are required. Applicants from non-English-speaking countries outside Europe must document English skills by an approved test. Approved tests are TOEFL, IELTS, Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English (CPE).
The successful candidate should be enthusiastic and highly motivated and be willing to work both independently and with other researchers. The successful candidate must also fulfill the requirements for admission to a doctoral program.
PhD Candidates are remunerated in code 1017, and are normally remunerated at gross NOK 449 400 before tax. There will be a 2 % deduction to the Norwegian Public Service Pension Fund from gross wage.
Engagement as a PhD Candidate is done in accordance with “Regulation concerning terms and conditions of employment for the posts of post-doctoral research fellow, research fellow, research assistant and resident”, given by the Ministry of Education and Research of 19.07.2010. The goal of the positions is to obtain a PhD degree. Applicants will engage in an organized PhD training program, and appointment requires approval of the applicants plan for a PhD study within three months from the date of commencement.
The position is of 3 years duration.
