Royal Caribbean Ships to Cut up to 20% of Energy, GHGs

Posted - April 20, 2012 - Environmental Leader

Royal Caribbean has awarded more than $60 million in orders to automation technology group ABB, to provide power and propulsion systems for two energy-efficient cruise ships. The ships are scheduled for delivery in fall 2014 and spring 2015.
ABB will supply complete electrical systems for the new ships. The delivery for each ship includes power generation and distribution systems, thruster motors, and two 20.5 MW propulsion systems including transformers, drives and two Azipod XO propulsion units. The Azipod systems can reduce the ships’ energy consumption and greenhouse gas emissions by as much as 20 percent, according to ABB, while providing greater maneuverability in all operating conditions.
Meyer Werft will build the 158,000-gt ships at its shipyard in Papenburg, Germany.
The ABB order for the first ship was booked in 2011 and for the second vessel in the first quarter of 2012. ABB said it recently won a number of large cruise ship orders for its Azipod propulsion in the first quarter of 2012.
In 2010, Royal Caribbean’s ships reduced fuel consumption by 4.7 percent per average passenger cruise day over 2009 levels, according to the company’s most recent Stewardship Report. It also reports using about 25,000 less metric tons of fuel than originally planned for 2010.
In 2011, the Port of Los Angeles installed electric accessory power, called Alternative Maritime Power, to supply ships from Disney Cruise Line, Princess Cruises and Norwegian Cruise Line.
