This is an exciting time to be joining the University of Southampton as we continue in our mission to change the world for the better.Building on our exceptional achievements, with an aim to be firmly established as one of the world’s leading universities, we are already known as a founding member of the UK’s prestigious Russell Group of leading research-intensive universities and feature in the top 100 global universities.
We are proud to employ great people who are passionate about their work. A successful university is made through the contributions of successful people.Our mission is to change the world for the better. This is a grand statement, but it is achievable with the support of more than 200,000 hardworking people who make up the students, staff, alumni, and community of our institution. The key word is ‘community’; this is how we see ourselves, as a group of people who share a common vision and goal. Together, we can learn, research and create innovations which can make a real impact on the issues of our world.
Description du poste
As renewable energy structures move into deeper water, the now established fixed foundation concepts must be replaced by anchoring systems. Current mooring systems are designed to resist peak design loads, which can lead to expensive mooring systems. This project will investigate the potential of a mooring system that absorbs some of the peak dynamic loading, such that smaller loads are transferred to the anchor, enabling smaller anchors that will be more cost effective and safe. Development of more efficient mooring systems is particularly important for the transition to renewable energy since the lower energy yield per structure compared to oil and gas producing structures requires many hundred more structures to be moored to the seabed for the same total energy yield.
Project hypothesis and scope:
The project hypothesis is that responsive mooring systems can provide a feasible option to reduce anchor size for floating facilities.
This project will involve investigation of the relationship between mooring line ductility and platform response through numerical analysis and experimental tank tests with high speed image capture and analysis. The University of Southampton has a large (138 m long) hydrodynamic testing tank equipped with digital image correlation capabilities, materials testing laboratory including high strain rate testing facilities and one of the largest supercomputer facilities in the country.
Maritime Engineering at UoS is co-located with Lloyd’s Register’s Marine division on the Boldrewood Innovation Campus providing the opportunity for this project to include development of design guidance for the adoption of responsive mooring systems.
The outcome of this project will be development of an effective responsive mooring system and design methodology that reduces the size of anchor required for floating facilities.
This project forms part of, and is funded by, a Royal Academy of Engineering Chair of Emerging Technologies in Intelligent & Resilient Ocean Engineering.
