The Royal Princess is the greenest ship in its fleet, according to Princess Cruises, which said the new ship has been designed to improve energy efficiency and reduce carbon emissions.

The 141,000-ton ship has a Wartsila diesel-electric powerplant with four 46F engines with a total output of 62 MW, and traditional shaft drives.

Partially thanks to the hull shape, the Royal Princess, which is 25 percent larger than the Ruby, has 15 percent less installed propulsion power, and is optimized to sail at 22 knots, according to Stuart Hawkins, senior vice president of newbuilds.

The propulsion, power generation and distribution facilities include two SAM Electronics 18 MW, 133-142 rpm diesel-electric low-noise propulsion motors. Other equipment include six 2.5 MW thruster drives, four diesel generators, six AC motors for bow and stern thrusters, two dedicated 11 kV switchboards for high voltage distribution, and eight distribution transfers for low voltage mains supply.

The bridge system includes a NACOS Platinum integrated navigation and automation control system.

Among the highlights of the Royal Princes is the Seawalk with glass and glazing by Somec Marine and Architectural Envelopes. The company also designed, manufactured and installed all the balcony sliding doors, balustrades and partitions from Deck 8 up to Deck 16.

On Deck 4, Somec provided external glazing for the Croone’s Bar and Seafood restaurant to withstand loads of 1,500 kg per square meter, and on Deck 14, a continuous glass wall for the bridge.

Hatecke has supplied the lifeboats with davits by Navalimpianti.

Galley suppliers include Sveba-Dahlen for bakery ovens.

The Royal Princess is classed 100A1 Passenger Ship with Lloyd’s Register (LR), and carries ShipRight, (SDA, CM), IWS, LMC and CCS notations, in addition to the Maltese Cross, assigned to ships constructed under LR special survey, in compliance with all rules, and the full satisfaction of the class society.
