Sirri Island

Sirri Island (Persian: جزیره سیری‎‎), is an island in the Persian Gulf belonging to Iran.

Sirri island is situated 76 km from Bandar-e Lengeh and 50 kilometres (31 miles) west of Abu Musa island. The island is one of six in the Abu Musâ Island Group (and is part of Hormozgan province). The island is almost 5.6 kilometres (3.5 miles) long with a width of about 3 kilometres (1.9 miles). It covers an area of 17.33 square kilometres (6.7 square miles). The highest point on the island is 33 metres (108 feet) above sea level. Like the other islands in the Persian Gulf it enjoys a warm and humid climate.

Sirri Island is the location of an oil platform that was once destroyed by the naval forces of the United States during Operation Praying Mantis on April 18, 1988. The platform was reconstructed later, after the war. The Sirri District includes the Sivand and Dena Oil Fields, Nosrat Oil Field, Alvand Oil Field and the Esfand Oil Field along with the Nasr offshore oil platforms. The airport located on the island (Sirri Airport (SXI)) is uncontrolled with a single 8,140' runway though Iranian military planes have been seen there.

The Iranian Offshore Oil Company (IOOC) has undertaken several major oil and gas development projects on the island including a $0.5 billion (USD) NGL Gas factory and a development contract to develop and increase production of the Iranian Nosrat oil field which is projected to increase crude oil production capacity from 5,000 barrels (790 cubic metres) to 16,000 barrels per day (2,500 cubic metres per day). Another project plans for the renovation of the crude oil export facilities and construction of two large crude oil storage tanks, each with 500,000 barrels (79,000 m3) capacity, on the island is also planned.[3]

Climate

Sirri Island has a hot desert climate (Köppen climate classification BWh).

In the summer, Sirri Island sees some of the highest average dew points of any place in the world, averaging above 28 °C (82 °F) in July and August. As a result, heat indices generally top 50 °C (122 °F) for most days during the summer.[4] This immense humidity causes summer diurnal ranges to be lower than in normal desert climates, and is a result of air flow from the warm waters of the Persian Gulf.
