recovers energy from the exhaust gas boilers, which would otherwise be lost. It is placed between the engines and generates 1.35 MW of power for use wherever needed, such as to boost hotel power. Fincantieri created and built the steam turbine, which has previously only been used on Vista-class ships within Carnival Cruise Lines’ fleet. Propulsion is dieselelectric and ABB’s Azipod units are used, each absorbing 16.5 MW, bypassing the need for a propeller shaft. “They make it much easier to manoeuvre in bad weather and in windy conditions because using pods means that there is more efficient control,” Mr Lunardi said. Another benefit is that there is more space inside the ship because the Azipods’ electric motors are not inside the ship. Three scrubbers are used, with two for the two big engines and one allocated to one of the three smaller engines. They were developed by Ecospray
Technologies and there were some challenges to overcome when it came to installing them, Mr Lunardi said. “The design of the scrubber was developed at the same time as the design of the vessel [and] the big challenge was to find a feasible co-ordination in a very narrow space,” he said. “The technical solution was fine-tuned but there were a lot of adjustments and we created a dedicated team especially to work with Carnival on the scrubber.” Particular attention was paid to the advanced wastewater treatment system (supplied by Scanship), which collects and treats grey and black water. Fancoils and LED lighting are used throughout Carnival Horizon to save energy. Like its sister ship, there is an emphasis on entertainment. To this end, features include an Imax 3D cinema and a brewery with onboard craft beer production. An impressive 63% of cabins are fitted with balconies. PST
