Milford Haven is a natural deep water port safely handling over 20% of the UK's energy. Widely recognised as an energy hub, it is the third largest port in the UK and the biggest in Wales.

In 2011, Milford Haven Port handled just over 71m gross tons of shipping, amounting to nearly 49m tonnes of cargo. A 24/7 operation, the Port offers a range of marine services as well as providing facilities and services for general cargo handling, fishing, marine-leisure, ferry operations and cruise calls.

The Port, along with the cluster of energy-related businesses along the Waterway, is a key driver of economic activity in Pembrokeshire, attracting inward investment and supporting thousands of jobs.
