This disclosure relates to a ship hull microbubble system used to reduce frictional drag on a ship hull while traveling through water. The microbubble system includes a water pump connected to an ejector which intern draws and compresses air within the ejector body. While in the ejector the compressed air becomes entrained within the pumped liquid as microbubbles creating a multiphase fluid which is then ejected at suitable pressure from the ship hull below the waterline through dedicated hull openings. The ejected air liquid multiphase fluid then creates plurality of microbubbles within the below water boundary layer reducing frictional drag generated by the hull as it travels through water. This disclosure has advantages when compared to related art through minimizing ship structure modifications, reducing wear on the ballast pump, operational autonomy from the ballast system, reducing the systems area footprint, independent control of the air injection rate, simplifying the installation through reducing existing pipework modifications and removing the need for riser pipes and additional tanks.
