Superlative luxury travel across the Atlantic

The RMS “Queen Mary 2”, known as “QM2” for short, is the flagship of the British shipping company Cunard Line, a subsidiary of the US Carnival Group. The “Queen Mary 2” was officially christened by Queen Elizabth II on 8 January, 2004, barely two years after the keel was laid. The “QM2” is one of the most famous ships of our time and was designed as a transatlantic liner in the tradition of the great steamships.

Today, it is one of the largest, most luxurious and, at over 800 million euros, one of the most expensive passenger ships in the world. Up to 3,090 passengers can be accomodated in 1,310 cabins on 13 decks and are looked after by a crew of 1,253. 

After the “Queen Elizabeth 2”, which also belongs to the Cunard Line, was taken out of service on 27, November, 2008, the “Queen Mary 2” is the last scheduled transatlantic liner.

The “QM2” surpasses the “Queen Elizabeth 2” from 1968 by almost 50 m in length, which until then was considered the longest passenger ship in the world. However, in an internal comparison, the “QE2” registers a speed advantage of 4 km/h. 

HydroControl VFR double regulating and commissioning valves from Oventrop secure the propulsion even with salty cooling water

The electrical energy for the entire ship is generated by four Diesel engines and two gas turbines, and also drives the the novel electric motors. These are cooled with seawater. Hydronic balancing of the cooling is done by means of Oventrop HydroControl VFR double regulating and commissioning valves. This ensures the optimum function of the above mentioned electric motors. HydroControl VFR valves made of bronze are especially suitable for cold seawater (max. 38 °C).

Among the decisive arguments in favour of the HydroControl VFR valves was not only the seawater resistance but also the handling of the functional elements located on one side. This is how Oventrop was finally able to join the list of German suppliers for this ocean giant.
