Gweinidogion Cymru yw'r awdurdod trwyddedu, hynny o dan Ran 4 Deddf y Môr a Mynediad i'r Arfordir 2009 (MCAA). Rhwng 2007 a 2013, yr Uned Caniatadau Morol oedd yn gyfrifol am geisiadau am drwyddedau morol. Yn 2013, gyda sefydlu CNC, trosglwyddodd Gweinidogion Cymru y rhan fwyaf o'r swyddogaethau hyn i CNC, sy'n gweinyddu'r system ar eu rhan.Prosiect Hinkley Point C
Welsh Ministers are the licensing authority under Part 4 of the Marine and Coastal Access Act 2009 (MCAA). Between 2007 and 2013, marine licence applications (and those under pre – MCAA regimes) were handled by the Welsh Government’s Marine Consents Unit (MCU). In 2013, with the establishment of NRW, the Welsh Ministers delegated the majority of these functions to NRW, who administer the system on their behalf.Hinkley Point C project
