Posters
Come meet the poster presenters to ask them questions and discuss their work
We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in the academic community. We look forward to seeing you there!
PO128: Subsea Substations
Arill Hagland, Product Champion Power Solutions, OneSubsea Processing
Abstract
Developing cost-effective solutions for offshore wind will be key to ensure that the expected growth in this sector will materialize and hence contribute to the energy transition and reaching our net-zero targets. The power transmission infrastructure of offshore windfarms is a major part of the overall cost, both in terms of capex but also opex. Today, the traditional way of collecting and transferring the power from the wind farm is by using offshore substations which principally is a conventional Oil&Gas platform without the hydrocarbons. The offshore substation is a heavy and costly unit and for deeper waters also needs to be floating with the additional challenges related to power cables and anchoring dynamics. The substation also contains a substantial amount of auxiliary equipment, such as fans and pumps, to account for the large environmental variations that occur offshore, i.e., large HVAC systems to control and maintain stable temperatures. This equipment also requires maintenance and therefore the need to transport and host service personnel both for regular intervals but also for unexpected incidents, with their associated risks and HSE concerns, is eliminated. By locating the substation subsea, where the environmental conditions are stable and cold, the system can be significantly simplified and both reduce CO2 emissions and improve efficiency. The subsea industry has more than 25 years of experience with power distribution, and by leveraging this experience and competence, subsea substations can be a vital contribution to making offshore wind a safer and more economically viable solution.
