Stena Superfast X (formerly Dieppe Seaways), a new fast Ro-Pax ferry, was launched at Dublin Port, for service between Holyhead (UK) and Dublin (Ireland), in March 2015.

The ferry is pwned by Stena North Sea. It recently underwent a comprehensive refit and upgrade in Gdynia, Poland, for service on the new route, which is one of the important tourism and freight gateways between Britain and Ireland.

Superfast X is the last in the series of four identical ice-class fast conventional ferries. It was originally ordered for Superfast Ferries’ new Baltic Sea services between Rostock port in Germany and Södertälje port in Sweden. It was launched in November 2000 along with its sister ships; Superfast VIII and Superfast IX. The construction was carried out at Howaldtswerke Deutsche Werft shipyard in Germany.

The ferry was later renamed multiple times by different owners before it was finally acquired by Stena Line in 2014.

Superfast X ferry conversion details

Hydrogenesis is the first hydrogen-powered boat to operate in the United Kingdom.

Stena Line awarded the conversion contract of Superfast X to MacGregor, part of Cargotec, in August 2014. The contract included conversion of RoPax ferry Dieppe Seaways (earlier name) to restore the original design of Stena Superfast X to suit operations across the new route between Holyhead and Dublin.

MacGregor supplied complete roll-on / roll-off (RoRo) cargo access equipment including the design, hardware and installation of bow doors, a bow ramp, a new water-tight door and a stern ramp. It also conducted feasibility studies to verify the interfaces between the onboard ramps and port-side equipment.

The vessel entered Nauta Shiprepair Yard in Gdynia, Poland, in December 2014. The shipyard renovated and modified the interiors in the public open spaces and renovated the cabins.

Also included in the conversion was alteration of cargo access equipment in the bow and stern, which involved the installation of bow and stern ramps, modification of the bow doors, and installation of a watertight door and a WT bulkhead in pipe tunnel that meets the UK stability regulations. Propeller blades for the main propulsion were renewed and a new livery was applied.
