1. An air supply system for supplying air to an outside of a hull of a vessel, the vessel comprising an engine, the air supply system comprising:
one or more turbocharger(s) for supplying a compressed main air flow to the engine of the vessel via a respective first flow path,
an exhaust gas recirculation, EGR, system for recirculating exhaust gas into the compressed main air flow supplied to the engine via a second flow path and
a third flow path for supplying a sub-flow of compressed air to one or more air discharge units, ADUs, wherein the one or more ADUs are configured to be arranged in the hull of the vessel below a waterline,
wherein the EGR system comprises a blower arranged in the second flow path for supplying exhaust gas to the engine,
wherein the first flow path and the second flow path have a first connecting path upstream of the blower and a second connecting path downstream of the blower, for providing a fluid connection between the first flow path and the second flow path, and
wherein the third flow path is in fluid connection with the first flow path and the second flow path downstream of the blower, such that the sub-flow of compressed air can be extracted from the first flow path and/or the second flow path.
