NYK YAMATAI Uses Air Bubbles to Reduce CO2 Emissions in Bulk Carrier

schematic of bubbler system

NYK's (Nippon Yusen Kaisha) Yamatai will have a unique method to reduce CO2 ... by injecting air bubble at the bottom of the hull.  This reduces drag between the hull and sea water.  The result is lower CO2 emissions. 

" ... first vessel engaged in overseas transport to make use of a permanently installed air-lubrication system using an air-blower ...   generate bubbles ... to the vessel bottom ... expected to result in 10 percent less CO₂ emissions from the vessel."
