Portsmouth-to-Spain gas-powered ferry to be built

Brittany Ferries Brittany Ferries said the new vessel will carry 2,500 passengers and will enter service in spring 2017

One of the largest gas-powered ships in the world is set to operate in waters between Portsmouth and Spain.

Brittany Ferries said the new £225m French-built "cruise-ferry" will be the cleanest and most environmentally-friendly ship in British waters.

Analysis

After several years of heavy financial losses, this is a big vote of confidence in Brittany Ferries, the French-owned company with an overwhelming market dominance on the Western Channel.

It's no surprise that its largest ferry will be used on the routes between Portsmouth and Spain. The services to Santander and Bilbao have been growing faster than crossings to France, particularly for lorries carrying fresh fruit and vegetables.

Its older ferries use heavy fuel oil and the company expects to be hit hard by new European regulations to limit sulphur emissions, which come into force in 2015.

Ordering the first cross-channel ferry to use liquefied natural gas will also require new refuelling infrastructure at Portsmouth ferry port.

But if it costs a lot to build, it could be relatively cheap to run. Anyone who has a gas-powered car will know that filling up costs a lot less than diesel.

Compressed natural gas emits 25% less carbon dioxide (CO2) than marine fuel oil and burns with no smoke.

Mike Bevens, group commercial director, said the ship, due to be ready in 2017, will mark "a new era" in ferry travel.

"Brittany Ferries and STX France [the company behind the build] have been co-operating for two years on a study regarding the feasibility of powering a cruise-ferry by liquefied natural gas (LNG)," he said.

As well as emitting less CO2, compressed natural gas is also free of sulphur and is very low in nitrogen oxide emissions, the company added.

The ferry's construction price is not much less than the price of a cruise ship and it will be built in the same St Nazaire shipyard as Cunard's Queen Mary 2.

It also costs two thirds the price of the A3 Hindhead tunnel and more than double the cost of electrifying the Great Western Main Line.

Brittany Ferries said the vessel will carry 2,500 passengers and will enter service in spring 2017.
