Ongoing Challenges for the Caledonian-Isles: A Chronicle of Delays and Maintenance

Jun 22, 2026
Caledonian-Isles has been facing a series of setbacks that are complicating its return to service, following extensive repairs and upgrades. Initially docked for eight months at Greenock after returning from Cammell Laird shipyard last September, the ferry recently encountered significant issues during sea trials, focusing on gearbox malfunctions and a troubling 'pitch control issue.' Engineers have been diligently working alongside the original equipment manufacturers to rectify these problems, which are deemed critical for the ferry's efficiency and operational safety.
The situation grew more urgent as the ferry was pulled back to dry dock in Ardrossan on June 20, discovering further complications related to pressure levels in its propulsion system. Despite initial optimism, further investigations indicated the potential for long-term repairs, leaving CalMac unable to confirm a return to service date until necessary inspections are completed. The vessel's sea trials resumed on June 26, with external contractors from Kongsberg supporting the efforts to address the propeller hub and pitch response challenges.
The anticipated window for the Caledonian-Isles to return to operation has already been impacted by other service schedules, particularly as the ferry will not return by July 7, coinciding with the off-service period of the 'Alfred' for maintenance until July 21. With additional disruptions anticipated due to maintenance on the 'Lord of the Isles,' CalMac is scrambling to implement a deployment plan that navigates these complex service challenges. This plan reflects a stark reality of limitations in available vessels during this maintenance phase, especially leading into the summer months when demand typically surges.
As CalMac officials continue to strategize, the ferry's operational status remains uncertain, prompting calls for patience and understanding from regional communities relying on these essential routes. The company plans to communicate any further updates on deployment strategies, especially concerning operations from July 22 onward, contingent upon the evolving situation with the Caledonian-Isles. Moving forward, the resolution of these mechanical issues is critical in re-establishing reliable service and maintaining community confidence in CalMac's ferry operations.
