#ferries - Brittany Ferries Cork-Roscoff cruise-ferry Pont-Aven began today its first sailing in 2019 on the seasonal route and will save energy and reduce fuel consumption thanks to the installation of two innovative devices on the ship's propellers.

Wärtsilä‘s EnergoProfin system is a small sub-prop, which is attached to the main propeller helmet, helping improve propulsion in water. Two of these devices were installed during the ship’s dry dock in December 2018. As a consequence fuel consumption and emissions have been cut by around 2% on every crossing.

This project is a small – but significant – step and it comes as part of a range of studies initiated through Brittany Ferries’ Research and Development program. But, as Vincent Coquen, Head of R&D, Energy and Environment for the company, explains, it is not just a question of developing practical and technical solutions for today such as the propellers on Pont-Aven.

“Sustainable development means looking to the future and studying innovative projects and technologies that could be used in either the short or longer term,” he said.

For the past two years, Brittany Ferries has partnered with CEA Tech in France. Several projects are underway, including the development of a long-range broadband link that would use land-based transmitters to obviate the use of satellite-at-sea. A second study focuses on hybrid energy solutions for Cap Finistère, Brittany Ferries cruise-ferry that sails from the UK to Spain. The last is exploring the long-term implementation of fuel cells for powering certain of the ship's on-board systems.

Brittany Ferries is also looking at the potential for wind energy. Flettner rotors, traction wings, or modern sails are at different stages of development, but could significantly reduce ship fuel consumption and therefore emissions.

“Of course, we must be cautious, checking the feasibility of integrating these technologies on board our ships, in terms of safety, reliability and profitability,” added Vincent Coquen. “But I am convinced that they will have a significant role in the equation that ship-owners must solve to achieve the zero emissions ship.”

Naval Visits focuses on forthcoming courtesy visits by foreign navies from our nearest neighbours, to navies from European Union and perhaps even those navies from far-flung distant shores.

In covering these Naval Visits, the range of nationality arising from these vessels can also be broad in terms of the variety of ships docking in our ports.

The list of naval ship types is long and they perform many tasks. These naval ships can include coastal patrol vessels, mine-sweepers, mine-hunters, frigates, destroyers, amphibious dock-landing vessels, helicopter-carriers, submarine support ships and the rarer sighting of submarines.

When Naval Visits are made, it is those that are open to the public to come on board, provide an excellent opportunity to demonstrate up close and personal, what these look like and what they can do and a chance to discuss with the crew.

It can make even more interesting for visitors when a flotilla arrives, particularly comprising an international fleet, adding to the sense of curiosity and adding a greater mix to the type of vessels boarded.

All of this makes Naval Visits a fascinating and intriguing insight into the role of navies from abroad, as they spend time in our ports, mostly for a weekend-long call, having completed exercises at sea.

These naval exercises can involve joint co-operation between other naval fleets off Ireland, in the approaches of the Atlantic, and way offshore of the coasts of western European countries.

In certain circumstances, Naval Visits involve vessels which are making repositioning voyages over long distances between continents, having completed a tour of duty in zones of conflict.

Joint naval fleet exercises bring an increased integration of navies within Europe and beyond. These exercises improve greater co-operation at EU level but also internationally, not just on a political front, but these exercises enable shared training skills in carrying out naval skills and also knowledge.

Naval Visits are also reciprocal, in that the Irish Naval Service, has over the decades, visited major gatherings overseas, while also carrying out specific operations on many fronts.

Ireland can, therefore, be represented through these ships that also act as floating ambassadorial platforms, supporting our national interests.

These interests are not exclusively political in terms of foreign policy, through humanitarian commitments, but are also to assist existing trade and tourism links and also develop further.

Equally important is our relationship with the Irish diaspora, and to share this sense of identity with the rest of the World.
