MV Stena Britannica

Stena Britannica has four main MAN diesel engines, producing between them 33,600 kilowatts (45,100 hp), and providing for a maximum speed of 22 knots (41 km/h; 25 mph). Two of the engines are rated at 9,600 kW (12,900 hp) and the other two at 7,200 kW (9,700 hp). The engines are connected via two gearboxes to two controllable pitch propellers. The two rudders, one behind each propeller, are of the Becker flap type with twisted leading edges. Control of the bow while docking is by two tunnel thrusters. Heat from the main engines is also used to heat the ship.[5]

The ferries, then designated "RoPax 55" ferries, were originally ordered from the shipbuilders Waden Yards (subsequently subsumed into Nordic Yards Wismar) by Stena Line in 2006. The total value of the order amounted to approximately €400 million.[3] Delays arose when Stena temporarily withdrew the order in response to economic difficulties being experienced by Waden Yards. After further negotiations the order was reinstated, but the new agreement included a price cut of 6% or approximately €24 million.[8] The ships having been completed, naming ceremonies took place on 8 June 2010 for Stena Hollandica at Hoek van Holland and on 19 October 2010 at Harwich for Stena Britannica.[9]

On the overnight crossing between Hoek van Holland and Harwich on 17 January 2018, a fire broke out on one of the refrigerated lorries and subsequently spread to other lorries but did not breach the lorry decks.[10][11] The vessel was subsequently taken to Schiedam and returned to service three days after the fire.

Stena Britannica is the focus of the Season 4 Episode 4 of the documentary TV show Mighty Ships. The episode first aired on 16 October 2011.[12] During filming a problem with the locking pins of the bow watertight door meant that, for 72 hours / six crossings, loading and unloading could only be carried out via the upper ramp while engineers worked night and day to resolve the problem.
