Exploration during the early 1970s discovered oil and gas to the east and west of Shetland. Shetland’s proximity to these oil and gas fields made it the obvious choice for an onshore terminal and by 1978 Europe's largest oil terminal had been built at Sullom Voe. Since then it has received oil and gas piped and shipped from the fields in the Northern North Sea for onward shipment by tanker.
Deeper water exploration discovered further gas reserves west of Shetland, prompting the construction of the huge Shetland Gas Plant. This facility, near the Sullom Voe Terminal, took its first gas in 2016, with the gas pumped from under the sea to the shore for processing.
North Sea oil and gas rapidly became one of Shetland’s main industries, including the Sullom Voe Terminal and associated support facilities, offshore activities and the developing decommissioning enterprises based in the isles.
