Engine Upgrade - MV Loch Fyne

April 2021

Mechanical Engineering / Diesel Engine Overhauls

Dales Marine Services was contracted to carry out four engine upgrades for Caledonian MacBrayne Ferries company. MV Loch Fyne was built in 1991 for the Isle of Skye crossing and now operating the Mallaig to Armadale route in western Scotland.

Scope of Work

The existing engines were replaced with new Volvo D13 engines, improving the vessel’s fuel efficiency and service reliability.

During the project, Dales Marine carried out works on the main engine foundations to modify the alignment and height to accommodate the newer engines’ new seating arrangement.

The engines’ cooling system required significant changes, new keel coolers were fitted, and Dales fitted a full new pipework system to suit the inlet/ outlet fitments on the engines.

Upon completion of the steelwork/pipework, the new engines were then laser aligned as per existing measurements taken on the drive shaft line. All laser alignments were carried out under the specialist works of a third party contractor.

Full electrical works were carried out as part of this turnkey project, from new cable install to engine controls and commissioning. Complete documentation and service reports were compiled and issued upon completion of the project. The vessel left Dales Marine’s shipyard two days ahead of schedule.
