A £5 million refit of all seven Stena Line ferries in its northern Irish Sea fleet has been completed ahead of the summer sailing season.

The work was carried out at the Harland & Wolff shipyard in Belfast over four months.

The refit programme was the first time that all seven vessels went into dry dock sequentially.

As well as co-ordinating more than 150 specialist onsite contractors, Stena Line also introduced temporary relief vessels to ensure that sailing schedules and customer service levels were maintained throughout the entire process.

Stena Line trade director for Irish Sea North, Paul Grant, said: “Our refit programme is a key aspect of our ship management operation to ensure that our vessels operate as safely and efficiently as possible.

“Apart from the range of upgrades we have made to our onboard passenger facilities, what’s particularly striking about this year’s refit is that the Stena Line fleet now carries our new company strapline emblazoned on the side of our ships…Connecting Europe for a Sustainable Future…which demonstrates our future sustainability ambitions.”
