The terminal, which will be able to cater for ships with up to 3,600 passengers, will be built at the currently derelict Princes Jetty site and will form part of the £5 billion Liverpool Waters redevelopment scheme.
Plans for the 10,000-square-metre terminal, which will be built on a suspended deck on steel piles in the river Mersey, had originally secured outline planning permission in April 2018.
