We are totally committed to ensuring that our vessels are as environmentally friendly as pos- sible.” Also according to Aponte, “MSC Cruises is committed to making green choices that keep the oceans blue.” The company’s energy effi ciency matches the industry-leading ecoship and clean- ship credentials and its green efforts have been recognized with a string of environmental certifi cations, along with awards recognizing its creative interior design, comfort, cuisine and service. The latest fl agship in the MSC fl eet is set to become a green paragon in the industry, with Bureau Veritas offi cially conferring the “7 Golden Pearls” award to the ship, which is one of highest awards for cruise vessels in recognition of the specifi c voluntary attention paid, from design and building to operation, to “Quality Health Safety Environment” (QHSE). The ship features an energy monitor- ing system, too. In order to decrease un- necessary energy use, a cabin monitor- ing system manages climate conditions in cabins and public areas at all times, automatically intervening in instances of wasteful overuse of air conditioning sys- tems. MSC Preziosa had its hull painted with a new “foul release” paint, with fl our polymers, a non-toxic substance which helps reduce CO² emissions through the reduction of fuel consumption. The ship also boasts a “Voyage Planning and Monitoring System” which is a ‘track and trace’ system used for planning and monitoring positions and itineraries of the MSC fl eet in real time with updates as frequent as every two seconds. Waste Management Advanced Water Treatment (AWT) is a system that recycles and treats waste- water. A distillation plant produces all the fresh water needed onboard using two evaporators and two reverse osmo- sis plants. In normal operating condi- tions, the ship does not require water from shore water stations. The vapora- tors are pollution-free and use a system of free heat recovery as its power source. Scanship provided the waste-water treat- ment plant (AWP) and also the vacuum food waste conveying and handling sys- tems. An agreement was also established with the Italian Consortium for Waste and Aluminum Recycling (CiAl), for the collection onboard of aluminum and dis- posal ashore to recycling facilities. Propulsion Machinery The propulsion machinery on the MSC Divina and the MSC Preziosa are differ- ent from those aboard their earlier sister ships thanks also to technological devel- opments that have taken place over the years. The MSC Preziosa is equipped with Converteam’s (now called GE En- ergy, Power Conversion) latest induc- tion-type electric propulsion machinery, fi rst applied on a cruise ship in 2010 aboard the Norwegian Cruise Line’s MS Norwegian Epic, which has a maximum rated power of 2 x 24 MW at 130 rpm at max 6.6kV. It is fi tted with propul- sion motors identical to the NCL vessel, with a power of 2 x 21,850 kW at 138 rpm and a maximum speed of 143rpm. In short, these motors, fed by two PWM MV7000 type frequency converters each (MV7612) are fi tted with a low resistive squirrel cage rotor, with no active insu- lated parts. The torque is produced by an induced magnetic fi eld into the rotor without the need to feed any current. The result is a simpler design, an im- provement in effi ciency by about 1% and a lighter design compared to earlier synchronous motor technology, result- ing from its shorter shaft and casing. The weight savings is close to 10%. Main- tenance is simpler too, as there are no excitation converters nor brushes, no ro- tating transformer parts, no rotating rec- tifi er and no winding in the rotating part. GE also delivered the fi ve alternators, 2 x 19.2MVA, 3 x 14.3MVA, providing 11kV voltage at 60Hz. The total alterna- tor power installed is 81.3MVA Navigation and automation As on the previous MSC vessels, the integrated navigation system is supplied by SAM Electronics, part of L3 Com- munications. The NACOS 65-5 system is identical to that of the previous sister ships. The bridge is laid out with safety desk aft in the same room. Also, the In- tegrated Automation System is supplied by Valmarine AS. Photo MSC Cruises 4D Cinema on the MSC Preziosa.MSC Preziosa’s Captain Giulino Bossi.
