Description du poste

The successful candidate will be enrolled into the Department of Mechanical Engineering at Politecnico di Milano where they will spend the first 18 months of their research. Thereafter, they will spend the remaining 18 months at Offshore Renewable Energy (ORE) Catapult in Blyth in the UK. The Politecnico di Milano will be responsible for awarding the PhD degree upon successful completion of the research programme.

ORE Catapult was established in 2013 by the UK Government and is part of a network of Catapults set up by Innovate UK in high growth industries. It is the UK’s leading innovation centre for offshore renewable energy.

Independent and trusted, with a unique combination of world-leading test and demonstration facilities and engineering and research expertise, ORE Catapult convenes the sector and delivers applied research, accelerating technology development, reducing risk and cost and enhancing UK-wide economic growth.

Active throughout the UK, ORE Catapult has operations in Glasgow, Blyth, Levenmouth, Aberdeen, the Humber, the South West and Wales and operates a collaborative research partnership in China. http://www.ore.catapult.org.uk

Abstract of research project

Dynamic cables are already used in the oil and gas industry. However, the numerical models used to model these required adjustment to account for the specific characteristics, dynamics and requirements of Floating Offshore Wind Turbine (FOWT) structures. In particular, subsea power cables on FOWT farms experience greater levels of mechanical stress due to the dynamic environment, leading to an increase in cable failures. This project will go beyond the state-of-the-art by optimising the cable configuration, whist accounting for cable fatigue, and using unique testing facilities for model validation.

In Year 1, a numerical model will be implemented integrating FOWT and cable models, including both static and dynamic response. The model will be able to reproduce the fatigue in floating wind cables for different cable systems and configurations.

In Year 2, the developed model will be used to identify the criteria that lead to the optimum cables solution in order to reduce cable fatigue and maximise FOWT performances.

In Year 3, the numerical solution will be validated through experimental tests in a representative simulated environment. The dynamic cable test rig at ORE Catapult, which allows dynamic cable technologies to be submerged in sea water whilst simultaneously undergoing electrical and mechanical fatigue testing, will be used to validation data for the modelling activities.

Expected results

The principal outputs of this doctoral research are described as follows:

1) Numerical model for a FOWT with its cable system

2) An optimization procedure to design the cables systems solution for FOWTs

3) An experimental database for numerical model validation
