The granting of a freeport status to two ports in Wales would generate billions of pounds say campaign backers.
Among the three bidders is Celtic Freeport which hopes to see the south Wales ports of Milford Haven and Port Talbot become the first such port in the country since 1980.
Milford Haven Port (including Pembroke Dock) is the UK's largest energy port while Port Talbot in neighbouring Neath Port Talbot County Borough has major steelwork plants.
They hope that their bid will be given the status which would lead to relaxed tax and customs rules benefitting both regions with £5.5 billion expected in new investment.
Celtic Freeport which Afloat reported in December, promises to create 16,000 new jobs. In addition to reducing harmful carbon emissions on the overall environment of Wales.
The freeport bid is backed by Associated British Ports (ABP), Neath Port Talbot and Pembrokeshire councils and Milford Haven Port Authority.
The ports and councils backed bid is based around maximising local benefits of a separate plan in the Celtic Sea for floating offshore wind projects.
