The FLOWLO Project
Introduction
Ireland has ambitious targets to deploy at least 37GW of offshore renewable energy in Irish waters by 2050. To reach this target, much of the renewable energy will come from Floating Offshore Wind (FLOW). With many technologies and little real-world experience, there is not yet consensus on infrastructure needs and best practices for the installation and maintenance of FLOW.
At present, there is no Irish port currently equipped for the large-scale roll-out of FLOW. Alongside this, the real-life challenges of offshore operations are often underestimated, particularly in the extreme metocean conditions of the Celtic Sea and the Atlantic Ocean.
FLOW LO (Floating Wind Logistics and Operations) will produce a series of real-world scenarios for small, medium and large-scale Floating Offshore Wind farms on the south and west coasts of Ireland, to be developed from 2030-2050.
Project Duration
June 2026 - May 2029
Objectives
The FLOWLO project will produce full lifecycle logistics scenarios and undertake techno-economic analysis to determine the Levelised Cost of Energy (LCoE) of each case study.
FLOWLO will optimise the scenarios by de-risking key marine operations through dynamic assessment; vessel navigation simulation to test execution plans at Cork Harbour, Bantry Bay and the Shannon Estuary; and numerical modelling and physical model testing for Operations and Maintenance (O&M) access for floating platforms. FLOWLO will provide a roadmap for the roll-out of FLOW in Ireland based on validated scenarios for Irish FLOW farms that are optimised for cost, logistic efficiency, and safety. There are 8 key objectives for the FLOWLO project
- Enhancement of logistics and LCoE modelling tools and identification of optimised logistical scenarios for FLOW deployment and O&M in Ireland.
- Assess the suitability and requirements of Cork Harbour, Bantry Bay, and the Shannon Estuary for becoming installation hubs for FLOW.
- Examine the wind farm installation process in great detail such that the feasibility of each operation can be determined and optimised if necessary.
- Use simulators for wind turbine towing operations and turbine integration activities to identify constraints, bottlenecks, and opportunities associated with working in Cork Harbour, Bantry Bay, or the Shannon Estuary.
- Develop an understanding of the applicability of using current O&M practices with respect to accessing floating platforms from either an SOV or a CTV.
- Examine, develop, and test innovative solutions for wind turbine access to determine weather windows for O&M and consider potential innovative solutions.
- Actively engage with key stakeholders to ensure project focus on critical aspects and disseminate knowledge to policymakers and the general public.
- Maintain Ireland’s leading position in ORE research by developing new research methodologies and publishing outputs in international journals.
Work Packages
Work Package 1 – Project management
UCC will serve as the Coordinator and will be responsible for the overall management of the project and the interface between partners and the SEAI. This will include: reporting results, findings, progress status, milestone accomplishment, as well as financial reporting.
Work Package 2 – Infrastructure requirements and logistics strategies
MTU and NMCI will both lead this work package with inputs from UCC and WEI. There are five objectives in this WP.
-
WP2-O1: To identify the port infrastructure requirements and viable logistics strategies for installation and maintenance of FLOW in Ireland.
-
WP2-O2: To define a set of theoretical FLOW farms including viable installation and O&M strategies and the associated infrastructure needs.
-
WP2-O3: To optimise the scenarios to ensure that they are cost-effective.
-
WP2-O4: To input viable logistics scenarios to WP3 and 4.
-
WP2-O5: Open access datasets will be released where possible to support industry in undertaking further research.
Work Package 3 – Navigation simulations
MTU and MNCI will both lead this work package with inputs from UCC. WP3 consists of the work required to set up, carry out, and analyse results from maritime navigation simulations for the various operations required within the Cork Harbour and the Shannon Estuary, for assembly and deployment of floating offshore wind turbine platforms. The five objectives of this work package are:
-
WP3-O1: Create numerical models of all relevant areas of Cork Harbour, Bantry Bay and Shannon Estuary within the MTU/NMCI maritime navigation simulation system.
-
WP3-O2: Carry out navigation simulations for FLOW operations accordance with parameters and details provided by WP2.
-
WP3-O3: Use simulation results to identify the optimum, possible and unfeasible environmental conditions, as well as optimum number and class of vessels required, for carrying out various FLOW operations within Port of Cork & Shannon-Foynes harbours.
-
WP3-O4: Identify any operational constraints relating to FLOW operations within Cork Harbour, Bantry Bay and the Shannon Estuary.
-
WP3-05 Propose an optimum strategy for FLOW deployment from the three site locations.
Work Package 4 – Physical and Numerical Model testing of O&M for FLOW
UCC will lead this work package with inputs from MTU and NMCI. This WP focuses on O&M logistics optimisation primarily by determining how accessibility to offshore wind turbines can be maximised to minimise turbine downtime. WP2 will initially provide logistics scenarios, and this WP will provide feedback on their feasibility and input values that should be used for further modelling. The work will concentrate on floating wind, but baseline modelling and testing will be required for fixed wind. The three objectives of this work package are:
-
WP4-O1: Understand the interaction between Service Operation Vessels (SOVs) and Crew transfer Vessels (CTVs) with fixed and floating wind turbines.
-
WP4-O2: Determine operational limits for undertaking O&M for floating wind platforms
-
WP4-03: Investigate solutions and innovations that will increase the weather window for offshore operations
Work Package 5 – Dissemination and Stakeholder Engagement
WEI lead this work package with inputs from all partners. The work package focuses on the communication and dissemination of the project's goals and outputs. There are four objectives in this work package:
-
WP5-O1: Utilising WEI’s network to get direct access to the biggest players in Irish offshore wind industry and engaging relevant stakeholders.
-
WP5-O2: Ensuring effective and eye-catching dissemination.
-
WP5-O3: Ensure the work of the project partners is communicated in an effective manner to raise awareness about the FLOWLO project and floating offshore wind energy amongst industry, researchers, and policymakers.
-
WP5-O4: Provide maximum impact and value to project stakeholders.
