LOC appointed to investigate floating offshore wind logistics

International marine and engineering consultancy LOC has been commissioned to report to Carbon Trust Floating Wind Joint Industry Project partners on the logistics and infrastructure of future floating offshore wind technologies.
LOC appointed to investigate floating offshore wind logistics

LOC Group, at the head of a consortium, has been selected by the Carbon Trust-led Floating Wind Joint Industry Project (JIP) to investigate the infrastructure and logistics challenges faced in the development, construction and maintenance of utility-scale floating offshore wind farms. The investigation report and recommendations, which has been commissioned by the Carbon Trust and  JIP partners DONG Energy, ENGIE, Eolfi, E.ON, innogy, Kyuden Mirai Energy, Statoil and Vattenfall, will help drive the commercialisation of floating wind technology.

The LOC consortium includes Portuguese offshore renewables consultancy WavEC and offshore geoscience and geotechnical engineering consultancy, Cathie Associates. Building on its members' extensive experience in the offshore wind industry, and drawing on new technical information and knowledge, the LOC consortium will outline key solutions for enabling the realisation of floating offshore wind farms with a capacity in the order of 500 MW.

The report will first categorise all floating wind platform solutions currently being trialed by the industry, in order to provide recommendations for overcoming foreseeable challenges in the construction of 500 MW wind farms, regardless of the type of floating technology being used. LOC’s report will outline the essential logistics needed for the assembly, storage and construction of floating offshore wind platforms, and, in particular, cover the details of dockside construction, marine transportation and installation operations.

“Port infrastructure will become absolutely critical to the successful development of floating offshore wind farms. Developers and owners will be looking for enhanced capabilities and capacities from the ports they use to support construction and maintenance” said RV Ahilan, Group Director of Renewables Advisory & Energy Technology at LOC Group with responsibility for overall delivery of the report. “The industry needs to recognise the logistics and infrastructure of floating offshore wind will be of a much greater scale than we have today. While the number of units may remain similar, the size and footprint of floating foundations are likely to be an order of magnitude greater than hitherto, thus challenging existing infrastructure boundaries.  The Carbon Trust and its partners acknowledge that this starts with a sound understanding of the process, and will include transferring knowledge from the oil and gas industry.”

Miguel Lopes, Head of Monitoring and Technology at WavEC and project manager for the study, added that the installation and maintenance of large floating wind farms will create a number of infrastructure and logistics challenges that go well beyond those faced by the fixed offshore wind industry today. This detailed study on dockside and offshore operations will bring these challenges to light and help ready the industry for these developments.

LOC’s report, taking into consideration all candidate floating platform technologies, will look at the logistical and infrastructure phases of development, installation and maintenance. It will scope the need for port infrastructure and equipment and the use of different vessels types; consider the needs of different turbine technologies; and account for project dependencies that can be avoided or exploited to reduce project risks and costs. The report will also look at how floating technology changes maintenance and repair programmes, including the decision to either conduct repairs on-site or tow turbines to port.

To date, LOC Group has acted as a Marine Warranty Surveyor (MWS) on more than 1,000 large energy infrastructure projects of all types, as well as thousands of other smaller marine operations, delivering marine warranty services on behalf of underwriters, their assureds, the assured’s contractors, or for self-insured clients. LOC has warranted over 30 projects in 11 countries including floating wind.

The success of offshore wind farms does NOT include something which will inevitably make it viable. The floating structures being discussed are the same as fixed structures now being used in that both concepts do NOT integrate neither wave nor tidal generators in the designs. This would vastly increase the power output to a single connection while at the same time reduce the capital costs associated with the structural components of the designs. Any government wanting to fund a project ensure a project that will produce increased power per unit should include this requirement in any monetary grant.
