February 4th 2015: It was announced that the Holyhead-Dun Laoghaire service operated by the Stena Explorer would not re-open for the 2015 summer season and in future Stena Line would focus all ferry crossings on the central corridor to the port of Dublin.
Stena Line today announced a consolidation of its services from Holyhead to Dublin Port. The company has stated that it will be concentrating on expanding its existing ferry service at Dublin Port while at the same time confirming that it is withdrawing its HSS Stena Explorer service from Dun Laoghaire Harbour.
Ian Davies, Stena Line’s Route Manager for Irish Sea South, said: “With two services operating approx. 10 miles apart we needed to make a decision in relation to what operation best serves the needs of our customers now and in the years ahead, and that operation is Dublin Port.”
Stena Line has operated the HSS Stena Explorer into Dun Laoghaire since 1995 during which time the vessel has carried a mix of passengers, car and coach traffic. The Dun Laoghaire service was successful for several years following its introduction, carrying over 1.7 million passengers annually during its peak in 1998. However, post the withdrawal of ‘duty free’ shopping, passenger and cars volumes declined dramatically and by 2014, less than 200,000 ferry passengers travelled through Dun Laoghaire Harbour. This represented a decline of over 90% in volume, making the route unsustainable.
Ian Davies added: “While we have enjoyed a very professional working relationship with Dun Laoghaire Harbour over many years, the economic realities of the current situation in relation to our business levels have left us with no choice but to close the service. Dublin continues to grow in importance, not only as the core freight port for Ireland but also as the key tourism gateway into Ireland.”
October 2015: “Sold to Karadeniz Powership Osman Bey, Istanbul, Turkey who were planning to convert it into a high-tech floating office. Proposal to be used as a Research and Development project that can generate its own power with its Vertical Axis wind turbine and high-tech solar panels to provide better security in case of an earthquake and high living standards in our shipyard in Turkey. As a first step, there would be minor revisions and only some areas in certain sections will be furnished as office space. Full revision will take time as the extensive design and R&D processes were still in progress.”.
October 27th 2015: Renamed ONE WORLD KARADENIZ.
November 1st 2015: Towed from Holyhead to Yalova, Turkey by tug BLUSTER.

November 22nd 2015: Arrived Yalova and entered Karmarine shipyard. The owner, Karadeniz Holding, has converted it into an “earthquake-resistant” floating office, research space and alternative power generator for the community of Istanbul. It is part of ‘Karadeniz’ Powerships project.

Were the HSS craft to big to fit through the entrance to Dover harbour ? Which meant they never operated for Stena from there .
Not sure what the operational limits of Dover Harbour are, but the crossings to Calais, Dunkerque or Boulogne would really be too short to maximise the onboard retail opportunities. Even the Pride of Dover/Calais had to slow down at times to give the shops time to process the queues before arrival, and there’d be no time to get a meal onboard if you crossed to Calais at 40 knots.
A nice article, Your technical data as a couple of incorrect points in. The ships in service speed was 40 knots, it was reduced to 25 knots in later years to reduce fuel consumption by only running two of the four turbines. the 40 knot service speed was well documented across all 3 HSS 1500 ships. A couple of the ex Stena Explorer masters are active in a Facebook group called ‘Stena HSS appreciation society. Along with the chief engineer who I believe stayed with the ship from the day the keel was laid up until she left Holyhead for the final time. They have provided a treasure trove of construction and in service photos, along with a wealth of information. They confirmed the maximum the Stena Explorer did was upwards of 50 knots. There was in fact an overspeed alarm which would sound when the ship went over a certain speed, possibly 45 knots. Anyway, yeah, the service speed was in fact 40 knots, reducing to 25 at the end of it’s life. With a much faster top speed. Great read though.
