Accelerating Offshore Energy Transition: Netherlands and Flanders Launch OFFSHORE FOR SURE Project

In the coming years, renewable energy at sea will receive a significant boost. Fifteen partners from Flanders and the Netherlands are pooling their expertise in the Offshore For Sure project to test five promising energy solutions and enhance their applicability in the energy system. The project’s objective is to accelerate the energy transition at sea and drive the sustainable blue economy in collaboration with knowledge institutions, regional, and societal organizations. The Interreg Flanders-Netherlands program for 2021-2027 supports this collaboration.

During the three-year duration of the project, the project partners will invest more than 10 million euros in the Flemish-Dutch border region. This investment is made possible in part by the European Interreg Flanders-Netherlands program and co-financiers. The consortium believes that these offshore energy solutions will contribute to a smarter, greener, and more co-operative Europe. BLUESPRING is the initiator behind the Offshore For Sure project idea and acts as the project coordinator.

Five Innovations and Supporting Partners

The five demonstration projects represent innovative solutions from technology developers with a proven track record and a clear plan for deployment in the fields of tidal energy, wave energy, offshore floating solar energy, and energy storage:

For their developments, the technology developers can rely on the knowledge and expertise of partners Bluespring, World Class Maintenance, International Marine; Dredging Consultants, Ecopower, Rijkswaterstaat, Parkwind, Ghent University, HOWEST, Deftiq, and the Zeeland Environmental Federation.

Collaboration Focused on Three Domains

Activities in the project have strong ties to the regions where they are conducted and have both local and international impact. Therefore, we are developing various services for different groups to maximize the gained experience and apply it internationally.

Policy & Public Engagement

As a significant portion of the developments take place at sea, outside the view of residents and their living environment, we aim to involve people in the projects, exchange knowledge, and thereby increase support and awareness. We work closely with nature and environmental organizations, cooperatives, and similar projects.


We are developing learning trajectories, including online and hybrid courses, based on the knowledge acquired during the project’s implementation. We promote student exchange and establish collaboration between educational partners in Flanders and the Netherlands.


We are working on certification services for testing in laboratories and at sea to ensure the efficiency and robustness of the developed systems.

Sustainable Perspective

The yield of our offshore energy transition is assessed by three types of end users: governments, project developers, and citizen cooperatives. Through their approval of our business cases, we attract further investments for both technology and projects. This should lead to bankable projects for the future, contributing to economic growth in the region and creating new jobs in the sustainable blue economy.

HydroWing to demonstrate next generation Tocardo Turbines at Morlais

30 MW at Morlais

HydroWing Ltd have been awarded a berth with 30 MW potential at Morlais a tidal site located in Angelsey, Wales, and operated by Menter Môn. The company plans a phased approach starting with a commercial demonstrator project in 2023 which will be operated by HydroWing’s newly established Welsh entity: HydroWing Tidal Projects Ltd. The initial project looks to cement the technology at the site, grow the Welsh team and develop the essential strong local supply chains and stakeholder relations to subsequently enable roll out toward the full 30 MW.
The device will be installed using the recently acquired Inyanga Entsha the new Dynamically-Positioned (DP2) Multi-Purpose Vessel. The Entsha, powered by DC Electric Propulsion, offers 35% increased energy efficiency leading to very low fuel consumption and high reliability unlocking efficient processes for the HydroWing’s installation, Operation and Maintenance. The vessel is currently in Appledore, Devon, where it is being upgraded with intelligent launch and recovery systems. Inyanga Entsha in combination with Tocardo’s reliable turbines and a low-cost mobilisation strategy are key to ensuring that tidal energy can compete with other renewable energy technologies.

Inyanga Entsha

HydroWing will work closely with the local supply chain in North Wales to deliver this demonstration phase. This commitment is strengthened with the joining of Marine Energy Wales cluster in early 2022. The front-end engineering design is currently being undertaken and over the next months HydroWing will undertake detailed analysis and design to ensure optimised configuration of the turbines.

Tocardo Tidal Turbines

The HydroWing device has been inspired by the Tocardo’s flagship OTP Project and the world’s largest single installation of tidal turbines (5 turbines). This 1.25 MW project has operated on the Eastern Scheldt barrier since 2015 with turbines arranged on a wing in a similar configuration to the HydroWing. The proven long term robustness, reliability and remote-control capability gives confidence to developing arrays of turbines on HydroWing. The key advantages of these turbines, aside from the proven reliability, is the compact nature of the device, allowing low-cost logistics using standard containers.

Tocardo OTP

This project will demonstrate the next generation Tocardo T-2si Turbines configured into the HydroWing Structure. The new turbines will feature enhanced blade performance and control innovation to provide low cost, clean, predictable and reliable electricity to the Local Grid. The new turbines integrated with HydroWing configuration will reduce the CAPEX while retaining the excellent robust reliability for which Tocardo are renowned.

Tocardo T-2si

The five installed turbines on the Eastern Scheldt barrier have each accumulated 6 years of operation with 95% availability proving it to be a robust, reliable, and low-cost system with limited need for physical intervention- giving confidence to integrating these turbines into HydroWing’s subsea system to take advantage of tidal sector’s biggest market segment.

HydroWing Technology

The HydroWing is a multi-rotor subsea device with three turbines mounted on a wing like structure which is stabbed onto a sub-structure, a modular gravity-based frame mounted on the seabed.

The device can be a single or double wing, depending on the depth of water at the site. The key advantages of the technology are the enhanced redundancy of the multi-rotor system and the high packing density capable of extracting 275 MW/km² of seabed space with robust simplicity and reduced CAPEX. The Power is integrated through the patented Turbine Control Hub mounted in the wing and electrical/ data connection is via wet mate connectors, allowing quick and simple installation and recovery.


Richard Parkinson, MD HydroWing: “We are very excited to demonstrate our HydroWing with the next generation Turbines at Morlais. Our key objective is to demonstrate that tidal energy can be cost competitive versus other renewable energy sources. We look forward to working with the local supply chain and collaborating with other developers at Morlais.”

Andries van Unen, CEO Tocardo: “For Tocardo, the development of the T-2si turbine marks an important milestone on the technology roadmap and will open the door to the offshore tidal market. With the HydroWing, our expertise, business partners and existing technology base, the Morlais project is the perfect stepping stone for Tocardo to determine our course and to claim our position in the market.”

Gerallt Llewelyn Jones, SRO Morlais Energy“Morlais welcomes Inyanga and we look forward to a productive relationship in progressing this important industry and creating benefits for the local and regional economy.”

UK government announces investment into tidal power

The UK government will invest £20 million per year in Tidal Energy

The UK government is backing tidal energy as part of its flagship renewable energy auction scheme, announcing today its biggest investment in a generation into tidal power. The UK government will invest £20 million per year in Tidal Stream electricity as part of its flagship renewable energy auction scheme, kickstarting a brand-new chapter for the tidal industry and creating jobs across the UK. Today’s announcement (24 November 2021) will unlock the potential for the emerging tidal power market.

AR4 – Contracts for Difference Scheme

As part of the fourth allocation round of the Contracts for Difference Scheme due to open next month, the UK government will ensure that £20 million per year will be ringfenced for Tidal Stream projects, giving the marine energy sector a chance to develop their technology and lower their costs in a similar way to the UK’s world-leading offshore wind industry. This will bring the total funding for this allocation round to £285 million per year.

Effects of this support mechanism: LCOE down

History has illustrated the effectiveness of the scheme’s design in keeping costs down – between the first allocation round in 2015 and the most recent round in 2019, the price per unit (MWh) of offshore wind fell by around 65%. Over time marine technologies have the potential to significantly contribute to our decarbonisation commitments and will supports hundreds of green jobs across the country, with projects currently in development in North-West Scotland, North Wales and the Southern coast of England.


Further details are not yet available but the headline is, assuming all other elements of the CfD framework remain unchanged, that £20m at the administrative strike price of £211/MWh enable the support of the installation of 34MW. This number is based  upon an analysis performed by Gavin Smart, ORE Catapult’s Head of Analysis & Insights

Tocardo T-1

Shipment of three Tocardo T-1 tidal turbines

Three T-1 turbines delivered in Pembroke

On behalf of the board of Tocardo BV I’m proud to share this news with the rest of the world.  After winning the tender last year, preparations, procurement, lots of manhours and persistence we have managed to ship three Tocardo T-1 tidal turbines. The bi-directional turbines have been successfully transported towards Pembroke dock where they will be installed on QED Naval’s Subhub community scale platform. The full systems integration will be conducted at the quayside. This is much safer and logistically easier than connecting up tidal turbine systems offshore.

The T-1 turbine

The T-1 is Tocardo’s community scale solution. By generating energy in a predictable and cost-effective way the T-1 is the best tidal turbine in its market segment with power outputs ranging from 40 to 100 kW. Due to its relatively small size, it can be installed in shallow waters (4 meters and deeper). The turbines are made to last with very minimal maintenance. The design lifetime is at least 20 years.

Cutting down LCOE

Logistics operations have a significant impact on the LCOE of our technology. We are convinced that it is better to install a larger number of medium sized turbines; turbines that can be brought to a (remote) project location by means of regular available (road) transport. The three Tocardo T-1’s will be utilized on the novel Subhub design. Subhub is a submersible, gravity based, foundation platform that supports every need of tidal turbines through life. After the system integration at the quayside the cost for the installation offshore is quite low because for the deployment QED Naval will be using low-cost harbor tugs only.

A big thank you

A big thank you goes out to: the team, contractors and all supply chain partners who helped us with their service and expertise to achieve this new milestone for Tocardo BV.
