Sullom Voe
The village of North Roe is on the shores of a second Burra Voe on the north Mainland side of the sound. South of there is the larger Colla Firth, separated from Quey Firth by Ness of Queyfirth. Next are Ollaberry Bay, Gluss Voe and Sullom Voe, which is a major inlet and at the longest of Shetland's many voes (Old Norse: "bay"). It contains the Sullom Voe Terminal operated by BP plc and itself has numerous bays and inlets. Sullom Voe terminates at the extraordinary Mavis Grind, a narrow isthmus separating the North Sea from the Atlantic Ocean.
