To propel the vessel, the builders se- lected Steerprop, based in Rauma, to provide two contra-rotating propulsors (CRPs), each 1450kW. Jussi Tarvairen,

Steerprop’s Sales Manager, said: “Expe- dition cruise vessels like Celebrity Flora are a growing segment, and our propul- sion technology and special expertise are perfect for sensitive environments and ice classes.”

He stressed the importance of the pro- pulsors’ hydrodynamic qualities with a specially engineered underwater body, and added that: “Noise levels and vibra- tions are extremely low, which was vi- tal for this particular vessel. In addition,

CRP provides outstanding maneuver- ability with its advanced azimuth pro- pulsor design and excellent ef? ciency.”

All of these features are critical for “op- erating in strictly regulated marine envi- ronments.”

Celebrity Cruise, in a release, notes: “Combined with a zero-speed stabilizer system, the DP system will choose a heading to minimize the roll and heave motions on the vessel, signi? cantly im- proving passenger comfort. To achieve a high level of redundancy and to meet the

Class requirements (PSMR* and DP1 /

DP-AM notation), the power and pro- pulsion plant of Celebrity Flora is dupli- cated and housed in two separate engine rooms.”

The vessel has Steerprop azimuth thrusters and SKF zero-speed stabilizers.
