Milford Haven Port Authority is responsible for the biggest port in Wales, and the sixth largest in the UK.  During 2008, the Port handled just under 53m gross tons of shipping which amounted to almost 36m tonnes of cargo.  The Port is in the heart of the Pembrokeshire Coast National Park, the only Coastal National Park in Great Britain.

As a trust port - an independent, commercially run organisation, the Authority has a statutory responsibility to both Government and its stakeholders, and is required to reinvest all profits to the benefit of the latter.

The first of the two Liquefied Natural Gas (LNG) facilities on the Haven has now been commissioned. South Hook successfully received 'Tembek' - the first LNG Carrier to enter the Port, on Friday 20 March. It is expected that Dragon LNG will be commissioned later this year, meaning that a potential 30% of the UK's gas requirements will be processed through the Port. 

With 25% of the UK's petrol and diesel provisions already being handled on the Waterway, Milford Haven is soon to become the new energy capital of the UK.
