At the turn of the 20th century, the island was a quiet rural community like many other small islands of Orkney, but its sheltered location led to three major upheavals on the island in the century. Until 1914, Flotta was a quiet farming community. In 1910, a population of 431 included two blacksmiths, four carpenters and three dressmakers.
Neolithic The presence of a
Burnt mound, a
cairn and a
tumulus indicates
Neolithic inhabitation of the island, however any other traces were likely destroyed by periodic
plowing of the fields on the island.
World Wars Everything changed with the arrival of the Royal Navy in Scapa Flow at the start of the
First World War. There is a photograph held by the Imperial War Museum in London that shows a boxing match taking place on Flotta in front of a wartime audience of 10,000 people. During the First World War, the island was home to a naval base. The
dreadnought HMS Vanguard sank nearby in 1917, reputedly the worst maritime disaster in UK waters. In the Second World War, the island was again used as a military base. 1918 saw the mass exodus of Navy personnel, and 1939 saw their return. After the Second World War the island had good piers and facilities, but a slowly declining population. It took until 1970 for fresh water to be piped to the island from Hoy.
North Sea oil In 1974,
Occidental Petroleum started construction of the island's
oil terminal. This became the largest major oil terminal serving the UK
North Sea, until
Sullom Voe oil terminal in
Shetland opened in 1978. It took only two years from the start of construction until the first of the crude oil was pumped into the terminal, during which thousands of workers were posted at the "camp" in Flotta to complete the facility as Britain's thirst for oil was growing by the day. The
Flotta oil terminal was opened by the energy minister,
Tony Benn MP, on 11 January 1977. The oil terminal provides the landing for the
Piper and
Claymore fields pipeline system. In addition, it provides a safe facility for the receipt and transshipment of oil produced from the UK Atlantic margins. ==Geography and environment==
