Following the launch of the world's largest 100% electric foiling vessel, 'Pioneer', at the beginning of 2022, Artemis Technologies has been inundated with enquiries from all over the world regarding its eFoiler technology across a range of applications. Whilst this first Artemis-eFoiler system was designed to service the workboat market with reliability and robustness the key criteria, performance of the vessel was compromised due to weight penalties incurred from the stringent structural requirements necessary to meet the MCA's Workboat Code. Whilst workboats have a consistent known operational profile, often working from a single port, with a requirement for a single location shore-based charging solution, other markets have a more varied duty cycle; for example, in water taxi or leisure applications where the daily mileage and access to charging infrastructure can vary significantly. For this classification of vessel, different regulatory rules result in lighter structures, opening the opportunity for smaller, higher performing composite foils delivering improved speed and range. This project will focus on the development and demonstration of a high-performance Multipurpose eFoiler Platform system, targeting a top speed of 40kts, with range of 70 nautical miles at cruising speed. In order to maximise the global opportunity of maritime decarbonisation Artemis has developed a 'bustle concept', an innovative change to the manufacturing approach which will facilitate large scale build of vessels at shipyards around the world, whilst manufacturing the high-value Mulitpurpose eFoiler Platform system in Belfast. The bustle concept involves the standalone manufacture of a section of the lower portion of the hull, which will be manufactured in Belfast and filled with an essential Artemis-eFoiler system. This is connected to the hull, at the location where the vessel is built. This novel solution opens the Mulitpurpose eFoiler Platform system technology to a variety of applications, at a wider range of locations. To successfully demonstrate the high-performance Multipurpose eFoiler Platform systems and bustle manufacturing concept, Artemis Technologies will work with passenger vessel operator, Condor Ferries, and luxury yacht maker, Cockwells, to build and deliver real world demonstration of a water taxi and a luxury tender, utilising the same base bustle/platform technology but with different top-hats, manufactured at different UK shipyards.

Crew Transfer Vessels (CTVs) are used daily in the offshore wind sector to transport technicians to undertake operation and maintenance (O&M) activities at windfarms. During operations they push against a wind turbine using a power-hungry "bollard push manoeuvre", drawing up to 80% of peak engine power for prolonged periods. Analysis predicts peak CTV demand of 524 vessels in Europe by 2035, with 30% of the current fleet below 20m. A typical operational day for a vessel this size could consume 600-litres of fuel. Operating for 275 days annually, with a traditional fossil fuel solution, this would generate 82,000tCO2e across UK and EU. The main challenge with the decarbonisation of high-speed vessels is the lack of viable range. Water is a very dense fluid requiring a lot of energy to propel a boat through water. The average range needed for daily CTV operations is greater than technically possible with standard vessels converted to pure battery or fuel cell operation. Over the last four years, Artemis Technologies has been developing a disruptive electric propulsion system, the Artemis-eFoiler. The innovation includes a high power-density electric drivetrain into an autonomously controlled hydrofoil, combining technologies from motorsport, yacht racing, and the aerospace sector. As an Artemis-eFoiler propelled vessel accelerates, the hydrofoils lift the hull up and out of the water, greatly reducing the wetted area and therefore drag. In 2021, Artemis launched the world's first 100% electric foiling workboat. Ongoing testing of the 11.5m prototype against its gasoline sistership, has proved that the vessel can provide significant improvements in energy efficiency (up to 90%) and ride comfort whilst generating zero GHG emissions. Analysis undertaken by Artemis investigated the viability of using a 12m electric foiling CTV to replace larger diesel CTVs operating at near shore wind farms. However, a major market barrier has been raised, with concerns regarding whether a foiling electric CTV could transit to the wind farm and safely transfer technicians onto turbines in up to 1.5m significant wave height, a market wide CTV operational requirement. Further detailed study has identified that directional thrust is a critical requirement for ensuring the challenging bollard-push manoeuvre can be completed effectively and safely. Therefore, during this project Artemis will evolve it’s existing 12m product offering from including a single, fixed propulsion pod to being able to accommodate a second, directional propulsion pod. This will ensure the 12m electric foiling CTV is capable & suitable for the CTV market and maximises the opportunity & applications for Artemis’ 12m vessels. In order to drive market uptake of the eFoiler technology in the offshore wind sector, this barrier needs to be addressed through a real-world demonstration. Consequently, the vision of this demonstration project is to develop, test and deploy a 12m 100% electric foiling CTV, "eFoiler Small-CTV" and shore-based charging infrastructure, to deliver zero emission crew transfer operations at Ørsted's Barrow wind farm. Initially the vessel will be delivered with the single propulsion configuration to complete basic training, trials, and demonstrations, and then it will be retrofitted with Artemis’ newly developed dual propulsion system allowing the vessel then to undertake ‘full’ trials & demonstrations.
