CalMac have a new mobile maintenance team, ready to assist in keeping the vessels operational.
The engineers and hydraulic specialists have been given campervans to help them travel to where they are needed on CalMac's west coast network.
The new seven-member team will carry out specialised inspections, monitoring and "proactive maintenance" while working with onboard engineering and vessel management teams.
The company said it was part of its effort to find "flexible and effective" ways of meeting challenges in the running of the fleet.
Working with Transport Scotland, CalMac stated the aim was to minimise service disruptions due to avoidable technical issues and reduce the routine maintenance that would normally take place during an annual overhaul.
Managing director Robbie Drummond said: "We are operating with an ageing fleet which is increasingly being stretched.
"We need to continue to find new ways to maximise our vessels operational resilience and have invested in a new team that will help mitigate potential problems before they escalate into something that impacts on service delivery."
"With our vessels setting sail around 360 times every day, this team has the mobility required to complete planned maintenance when and where it is needed on the network minimising disruption to service due to technical issues," added Robbie.
