Anemoi Marine Technologies has been awarded a grant from the Clean Maritime Demonstration Competition (CMDC) Round 4 for a smaller version of its Rotor Sails. The aim of this competition is to fund real world demonstrations, trials and feasibility studies into clean maritime technologies that reduce greenhouse gas emissions.

The CMDC Round 4 is part of a suite of interventions launched by the UK Shipping Office for Reducing Emissions (UK SHORE) and funded by the UK Department for Transport (DfT). UK SHORE is a GBP 206 million initiative focused on developing the technology necessary to decarbonise the UK domestic maritime sector.

Rotor Sail for mid-range vessels

The funding covers a GBP 1.9 million project and will allow Anemoi to develop and test a new 3.5-metre diameter by 24.5-metre high Rotor Sail design. It funds the design activities, building, and testing of the demonstrator for the innovative new drive system, which will be manufactured by test rig experts, Pressure Design Hydraulics Ltd, and housed at VINCI Technology Centre. Of the total project costs, Anemoi is eligible for over GBP 1.2 million.

Anemoi continues to have much success with its commercially proven 5-metre diameter Rotor Sails (available now in heights of 24, 30 and 35 metres) with installations on Kamsarmax and VLOC vessels.

The 3.5-metre diameter Rotor Sail will be well suited for mid-range vessels, such as handysize and ultramax bulkers, chemical and product tankers, and RoRos. The grant will enable Anemoi to assess the performance of its new design in a safe and controlled environment close to its UK design offices.

By expanding Anemoi’s product range, more vessels can make use of wind propulsion, helping to make a bigger difference to the shipping industry as it continues its decarbonisation journey.

Previous pilot installation

Thanks to Anemoi’s background in the bulker segment, the company already has experience with mid-range vessels. Its pilot installation on the m/v Afros, an ultramax vessel, has sailed successfully for six years.

The vessel was installed with Rotor Sails on Anemoi’s unique longitudinal rail deployment system. This rail deployment system, which allows the Rotor Sails to be moved along the deck to ensure cargo operations are unimpacted, will be retained for the new 3.5 x 24.5-metre Rotor Sails as driven by vessel requirements.

Project partners

The year-long 3.5-metre development project will be further strengthened by numerous partners, each specialising in distinct elements. Dynamics analysis will be undertaken by project partner Frazer-Nash Consultancy, which will support the development of the demonstrator.

A regulation and certification assessment will be led by Stehr Consulting Ltd in collaboration with Lloyd’s Register. UK-based vessel operator an project partner, Victoria Steamship, will assist by providing vital insights into the needs of stakeholders.

Market research and UK supply chain analysis will be conducted by Connected Places Catapult, which will help Anemoi quantify the market opportunity for establishing a UK manufacturing operation to serve European and Transatlantic markets.

Lastly, Connected Places Catapult will conduct a feasibility study into the benefits of combined integration of Future Fuels and Rotor Sail technology, reinforcing the importance of Rotor Sails in the decarbonisation of shipping. These diverse collaborative endeavours are key to accelerating progress in the development and implementation of energy-saving technology within the shipping industry.
