SEA CLIMAVER ®: SCENARIO
A 140 000 gross tonnes cruise ship - 3 300 passengers - 1 400 passenger cabins
Assumption : SEA CLIMAVER ® replacing traditional steel duct for all straight ducts inside the passenger cabins . ductwork solution ( metal duct + insulation ), Sea Climaver ® reduces the weight of your average HVAC ductwork by up to 65 %.
“ This translates directly into reduced fuel consumption , which in turn decreases green house gas emissions ,” Miettinen points out .
Miettinen wasted no time in getting the international Saint-Gobain team together and pitched them the idea . With the green light from colleagues , he contacted Royal Caribbean International and Meyer Turku shipyard : would they be interested in a pilot ?
“ First , we made mockup to test the concept , and received an OK also from classification society . The next step was finding a suitable pilot .”
Pretty soon , Sea Climaver ® found a piloting opportunity , and not a modest one at that : Sea Climaver ® solution was to cover a test area of 1,500 square metres on Icon of the Seas , Royal Caribbean ’ s newest cruise ship .

TOP PERFORMANCE FROM NEWCOMER
With Icon of the Seas sailing off from Turku in December 2023 , there ’ s already some experiences on the performance of the Sea Climaver ® system . Miettinen says that Sea Climaver ® has met all expectations and even exceeded them .
“ Energy efficiency of the system is exceptional and it ’ s very quiet , too .”
Great thermal resistance , reduced thermal bridges and excellent airtightness help reduce energy consumption and limit greenhouse gas emissions from the ventilation system .
“ Now that we ’ ve proven the concept on Icon , we will do a bigger area on Star of the Seas ,” Miettinen reveals . In addition to new vessels , also the retrofit market will benefit from the new system . n
