The first ever UK domestic dual-fuelled new build vessels will feature fully integrated Wärtsilä propulsion machinery packages.
Wärtsilä will also supply extended engineering and site support services. The two ships, both 102 metre long ro-ro passenger ferries, are being built for Caledonian Maritime Assets Ltd (CMAL) based in Port Glasgow, Scotland. The contracts with Wärtsilä were recorded in December 2015.
Besides being the first dual-fuel vessels for CMAL, they are also the first ever dual-fuel ships to be built in the UK. These will be built by Ferguson Marine Engineering Ltd. The yard is located on the River Clyde in Glasgow.
In addition to site support services, Wärtsilä will supply each of the two ships with two 6-cylinder Wärtsilä 34DF main engines capable of operating on either LNG or conventional diesel fuels, two 6-cylinder Wärtsilä 20DF auxiliary engines, horizontally offset gearboxes, shaft lines, seals and bearings, controllable pitch propeller systems (CPP) including the Wärtsilä Energopac optimised propulsion and manoeuvring system, tunnel thrusters, the Wärtsilä LNGPac storage and supply system, plus extended commissioning and engineering. The ships will feature a twin screw dual-fuel mechanical propulsion driveline.
The ferries are scheduled to enter service during the second half of 2018. They will operate on various routes along the west coast of Scotland.
