for the actuator were not included in the system’s engineering manuals provided by RR Marine that were carried on board Hebrides.
RR Marine had also not issued any information regarding the maintenance or inspection of the actuator.
The MAIB report said: “The absence of service instructions for the actuator’s inspection and maintenance that were available from its manufacturer was pivotal to the failure.”
It has issued a recommendation to Rolls-Royce Marine aimed at ensuring service instructions are made available to service engineers and in documentation provided to vessels.
The MAIB has also recommended CalMac Ferries Ltd ensure recommendations for safety critical system upgrades received from manufacturers are properly documented and processed and that its crews are better prepared to deal effectively with propulsion failures.
CalMac has issued a technical bulletin to its major vessels that requires all propulsion controls, including emergency controls, at all stations to be tested regularly and it has conducted its own investigation of the incident.
Rolls-Royce Marine has issued a service letter to all users of the HeliconX propulsion control systems and a service procedure for the linear servomotor.
A CalMac spokesman said: “We note the MAIB’s report, which largely confirms the findings of our own investigation into the incident.
“Since the grounding in September last year we have put in place a number of processes to mitigate the issues raised and will continue to monitor these areas to ensure our procedures meet the highest possible standards and give our customers assurance that we take their safety very seriously.” TWINS Emelia and Elliot Goodall have settled happily into life at home after being born 13 weeks early.
