QM2 heads for Fort Lauderdale
Cunard Line's Queen Mary 2 is now on its 14-day maiden voyage to North America, after Cunard's traditional royal naming ceremony performed by Queen Elizabeth II. The christening took place in Southampton, England, rather than at the building yard, Alstom's Chantiers de l'Atlantique in St. Nazaire, France.
The ship will call at Madeira, Tenerife and Las Palmas in the Canary Islands and Barbados and St. Thomas in the Caribbean before arriving at Fort Lauderdale on January 26.
The first true transatlantic liner to have been built since QE2 in 1969, Queen Mary 2 is the largest (151,400 tons), longest (1,132 feet/345 meters), tallest (236 feet/72 meters), widest (135 feet/41 meters) and most expensive ($800 million) passenger vessel ever built.
All of that space has given Cunard the scope for a huge variety of passenger amenities. Queen Mary 2 features 10 dining venues with Chef Daniel Boulud serving as Cunard's culinary advisor and Chef Todd English operating a Mediterranean speciality .
The liner also has the only Canyon Ranch SpaClub at sea, the world's first planetarium at sea, the largest ballroom at sea, the largest library at sea, and the largest wine collection at sea, as well as a Veuve Clicquot Champagne Bar, a two-story theater, a casino, five indoor and outdoor swimming pools, hot tubs, boutiques and children's facilities complete with British nannies
Pushing all this through the Atlantic at a maximum speed of of some 30 knots, is a 157,000 hp environmentally-friendly CODAG (combined diesel and gas turbine) power plant plant generating electrical power for propulsion and all shipboard systems.
Propulsion is by four electrically driven Rolls-Royce Mermaid podded drives, two fixed and two azimuthing.
The diesel component of the CODAG plant is four Wartsila 16V46 , each with a maximum continuous output of 16,800 kW (22,840 bhp) at 514 rev/min. For redundancy, the diesel generating sets are housed in two separate engine rooms.
The Wartsila 46 EnviroEngines use an electronically-controlled common rail fuel injection system that enables injection pressures to be kept sufficiently high at all engine loads and speeds - even at the lowest levels - to achieve clean combustion with no visible smoke emissions. The EnviroEngines will be particularly beneficial for use in port, as they are designed to produce no visible emissions even when lightly loaded for producing energy for lighting, air conditioning and other hotel systems.
The gas turbine part of the package is two GE LM2500+ aeroderivative gas turbine-generator sets .
"We are delighted that our LM2500+ gas turbines were selected to power this elegant and historic achievement in naval architecture and engineering," said Karl Matson, general manager of GE Marine. "This project also marks a milestone for GE, as the LM2500+ gensets are being used for the first time in a 'dual gas turbine' installation on a cruise ship in a combined diesel and gas turbine arrangement.
The gas turbines were manufactured at GE Marine's Evendale, Ohio facility; the generator sets were packaged by GE Energy in Houston, Texas.
Each gas turbine-generator set contributes 25 megawatts to the ship's overall 118 megawatts of installed power.
GE specially designed the two LM2500+ packages for Chantiers de l'Atlantique, to be some 35 tons lighter than previous LM2500+ marine gas turbine installations.
According to Chris Dalston, manager of commercial marine sales for GE Energy, "What makes this application unique is that the compactness and low noise and vibration characteristics of the packages. These design features allowed the shipbuilder flexibility, especially with respect to the placement of the gas turbine gensets. The volume and weight of ducting for the combustion intake, exhaust and package ventilation are significantly reduced, thereby increasing the ships' available space for cabins and public areas."
The redesigned package also features the next-generation Woodward Micro Net Digital Control turbine control system. The controls manage all the systems of the package, including engine fuel management, package sequencing, package condition monitoring and interfacing to other systems aboard the ship.
GE Energy also provided the lightweight, redesigned LM2500+ packages for Princess Cruises' newbuilds -- Island Princess, Coral Princess, Diamond Princess and Sapphire Princess. These vessels feature one GE LM2500+ gas turbine-generator set in a CODAG configuration with two diesel generator-sets.
To date, 22 LM2500+ and four LM2500 GE gas turbine-generators are in operation or slated for service on 17 cruise ships
