Energy jobs in Milford Haven

Why the Waterway matters

Milford Haven sits on a deep, sheltered natural harbour, and that depth has drawn energy businesses for generations. The Port of Milford Haven describes itself as the UK's largest energy port, with terminals on both shores of the Waterway handling a large share of the country's gas and oil supplies.

For job seekers, that means steady demand for process operators, maintenance technicians and marine staff, plus bursts of contract work whenever a plant shuts down for planned maintenance. Marine renewables and floating wind are now adding engineering and port roles on top.

Key energy sites around Milford Haven

Pembroke Power Station opened in 2011 and was designed to run almost continuously. It now starts and stops its gas turbines far more often to balance wind and solar output on the grid, which has raised the value of electrical, controls and reliability skills. Valero's refinery is one of only a handful still operating in the UK and receives its feedstocks by ship through the Waterway.

Hydrogen and carbon capture have also been studied for the Waterway's industrial sites as part of wider plans to cut emissions from South Wales industry, so engineers with process safety and gas experience may find these skills in growing demand.

Marine energy and floating wind

Pembroke Dock Marine, funded through the Swansea Bay City Deal, is redeveloping parts of the historic dockyard so that marine energy and floating wind companies can build, test and maintain equipment there. Alongside it, the Marine Energy Test Area, led by Marine Energy Wales, offers pre-consented sites in and around the Waterway for testing wave and tidal devices, and the Offshore Renewable Energy Catapult has set up a marine energy engineering centre in Pembroke Dock.

Further out, The Crown Estate has awarded seabed rights for floating wind farms in the Celtic Sea to Equinor, Gwynt Glas and Ocean Winds. These projects are at an early stage, but they will need survey, consenting, marine operations and maintenance staff over many years.

What employers hire for

Operations and maintenance

Terminals, the refinery and the power station run around the clock, so shift operators, mechanical fitters, electricians and instrument technicians are the core of local hiring. Experience with permits to work, isolations and COMAH-regulated sites is highly valued.

Shutdowns and contract work

Planned maintenance shutdowns, often called turnarounds, bring in scaffolders, riggers, welders, pipefitters, inspectors and supervisors for a few weeks at a time. Day rates are typically higher than pay for equivalent permanent roles, but the work comes in peaks and you may travel between sites.

Marine and port roles

Pilots, tug crews, mooring teams, harbour engineers and logistics staff keep ships moving safely, while marine renewables projects recruit engineers, technicians and vessel crew.

Learning the skills locally

Pembrokeshire College in Haverfordwest opened a Welding and Fabrication Centre of Excellence in 2023 with floating wind in mind, and it runs an Energy Transition Skills Hub supported by Shell UK. The hub includes a process control simulator and covers floating wind, hydrogen, solar, tidal and gas power, which makes it a useful step towards control room work. Course details are on Pembrokeshire College's website.

For offshore and marine roles, employers usually ask for basic safety training, such as GWO courses for wind or OPITO-approved courses for oil and gas, along with a medical. Check what each advert specifies before you book.

Travelling around the Haven

Milford Haven station is the end of a branch line from Johnston, with Transport for Wales trains to Carmarthen, Swansea and Cardiff, many of them continuing to Manchester. Pembroke Dock has its own line to Carmarthen. The Cleddau Bridge on the A477 links the two sides of the Waterway, and Irish Ferries sails from Pembroke Dock to Rosslare.

In practice most site workers drive, because shift times rarely match bus and train timetables. Many people live in Haverfordwest, Neyland, Pembroke or Tenby and commute across the Waterway.
