The Finnish engine manufacturer has published new orders for its dual-fuel segment. The first ever UK domestic dual-fuelled[ds_preview] new build vessels will feature fully integrated Wärtsilä propulsion machinery packages. The company will also supply extended engineering and site support services. The two ships, both 102 m long RoPax ferries, are being built for Caledonian Maritime Assets Ltd (CMAL) based in Port Glasgow, Scotland.
Besides being the first dual-fuel vessels for CMAL, they are also the first ever dual-fuel ships to be built in the UK, delivered by the yard Ferguson Marine Engineering located on the River Clyde in Glasgow. »This project highlights the fact that high-end, technologically advanced commercial shipbuilding is again present in Scotland. We value Wärtsilä’s contribution as an important partner, not only in providing us with the latest dual-fuel technologies, but also through its comprehensive range of project support competences. The project is at the forefront of marine engineering within the global ferry sector,« says Ferguson´s Managing Director Liam Campbell. In addition to site support services, the Finnish manufacturer 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.
Second, Wärtsilä has been awarded the contract by Gdansk Shiprepair Yard Remontowa to supply a comprehensive scope of engines, propulsion machinery, integrated automation systems, and gas handling systems required for the mid-life upgrading of two RoPax ferries and their conversion to operate on LNG fuel. The »Spirit of British Columbia« and the »Spirit of Vancouver« are the flagship vessels of British Columbia Ferry Services based in Victoria, Canada. The work on the first of these ships will be carried out during the 2017/18 winter season, and during the following winter season for the second vessel.
The full scope of Wärtsilä’s supply includes four Wärtsilä 34DF dual-fuel engines with fuel gas systems, integrated automation systems and power management systems, the Wärtsilä Pro-Touch propulsion control system, the power transmission systems comprising two gearboxes, the Wärtsilä LNGPac comprising the fuel storage tank, bunkering station, gas detection system and process control automation, Wärtsilä rudders, site representation and integration engineering, and crew training. The upgrading work will involve surveying the stern tube and renewing components, surveying and overhauling the controllable pitch propeller (CPP) hubs, redesigning and renewing the CPP propeller blades, surveying, renewing and overhauling the oil distribution boxes, and renewing two bow thrusters and E-motors.
