SPOTLIGHT ON SWEDEN


SUSTAINABLE TECHNOLOGY DEVELOPMENT AT SEA


Test Site Skagerrak is a test and demonstration area for sustainable marine and maritime innovation who want to establish a partnership between technology developers, suppliers, research and public activities


RARE OPPORTUNITIES The easily accessible waters around Lysekil and Orust offer testing opportunities in mild climates in regard to waves and currents which, compared to other international test sites, is rare. The conditions around Skagerrak are attractive for testing of components and systems, energy technology for areas with lower energy flows and scale prototypes for areas with high energy flows.


FACILITIES Islandsberg is a site which has been continuously developed since 2004 for experiments on renewable electricity from waves and environmental studies and provides a depth of 25-30 metres, a flat sandy bottom, marine switchgear (AC/ DC/AC) connected to the power grid, power cables, net and single cables, camera surveillance, wave measurement as well as a measuring station on land. Test areas include strength, survivability, renewable energy production and environmental impact.


MARINET 2 Islandsberg is part of the H2020 funded network Marinet 2. Due to this,


the test site is available to developers from all over Europe.


In the vicinity of the test zones there are a number of factors that make it ideal for the development of marine innovations… • Deep-water port with five cranes and a capacity of up to 80 tons


• Proximity to the marine service company for small and large installation and maintenance


• Continuous measurement including wave climate in several locations


• Workshops at the dock for repairs, spare parts, tools and control equipment


• Transport boat out to test beds • Monitoring facilities • Marine instrumentation • Underwater robots work and inspection


• Proximity to qualified research • Residential and office staff for testing

permission for a single test project, which we as a development company usually cannot afford. With a Swedish test site in place, we would at an early stage at home have the opportunity to test and develop our products and ideas, with all the practical, financial and administrative advantages.”


THE WAY FORWARD Test Site Skagerrak are currently developing partnerships and cooperation with academia and institutions.

Reliability in a sea of risk


In today’s investment environment, the perception of technical risk is dependent on how confident the investors are that marine energy devices will perform their required functions under stated conditions for a specified time


In order to achieve this reliability, it is important not only to predict the life of a product, but also to investigate and take into account the sources of variability and their influence on life prediction. The Reliability in a Sea of Risk (RiaSoR) project addresses the strategic need for the marine energy industry to learn lessons on the key engineering challenges that underpin the reliability and future Levelised Cost of Energy (LCoE) reductions of emerging wave & tidal device technology.


PROJECT DETAIL The project has adapted, evaluated and demonstrated the value of utilising a reliability methodology called Variation Mode and Effect Analysis (VMEA) for ocean energy sector. It is supposed to establish industry best practices in reliability testing for wave & tidal devices through improved load measurements and verification, standardising design guidelines for marine energy systems and increasing safety in marine energy operations.


three leading European research and testing sites, European Marine Energy Centre (EMEC), Research Institutes of Sweden (RISE) and Offshore Renewable Energy (ORE) Catapult, in order to develop industry approved reliability testing practices. These practices will be applied by the research and testing sites, ensuring consistency and robustness of testing to demonstrate reliability across wave & tidal technologies.


The overall technical approach is driven by RISE, who brings their experience in reliability testing from the automotive industry. RISE focus on developing a VMEA framework and adapting the framework for structural reliability analysis. EMEC concentrates on the adaption for mooring and foundation analysis. ORE Catapult focuses on the implementation for electrical power system analysis.


Marine energy converters (MECs) In the reliability design process for MECs, both variation sources and lack of knowledge must be accounted for. Loads acting on a MEC vary according to different sea-states, both over time


and between sites. Methods for the assessment of the reliability of a MEC include many different levels of complexity, both regarding the mathematical modelling and the statistical modelling.


LOWER LCOE


VMEA methodology and practices in the RiaSoR project will bring the developers closer to the ultimate aim of reducing Health Safety and Environmental (HSE) risks, technological risks, operations & maintenance (O&M) costs, all which will lower the Levelised Cost of Energy (LCoE) for the sector.
