Sullom Voe tide times

Sullom Voe is a deep fjord-like inlet on the north Mainland of Shetland, cutting south from the north coast between the peninsulas of Northmaven to the west and Delting to the east. It is the largest voe in Shetland — 15 kilometres long and up to 2 kilometres wide, with a maximum depth of 30 metres. The spring tidal range inside the voe is 1.6 metres above Chart Datum, slightly larger than Lerwick and Scalloway due to the voe's more open northern exposure. Tidal streams at the entrance to the voe, where it narrows between Gluss Isle and the mainland, run at 2 to 3 knots at springs — the most energetic water in the immediate area.

Sullom Voe Terminal, opened in 1978, was Europe's largest oil and gas terminal when constructed. It handles production from the Brent and Ninian oil fields and other North Sea fields via two 160-kilometre underwater pipelines from the East Shetland Basin. At peak production in the 1980s, supertankers of 400,000 tonnes deadweight loaded here; the scale of the infrastructure remains extraordinary even at reduced throughputs. The terminal is a controlled area and not publicly accessible, but the approach road along the east shore from Brae gives clear views of the jetties, the flare stacks, and any tankers alongside. This industrial seascape, set against the Shetland moorland and the water of the voe, has a stark visual quality unlike anything else on the British coast.

The voe itself, away from the terminal, supports significant wildlife. Eider ducks are present in numbers year-round, particularly in the shallower northern sections where the shellfish beds sustain large flocks through winter. Long-tailed ducks winter in the voe from October through April, sometimes in flocks of several hundred diving in the deeper central channel — they are among the most striking winter duck species in the UK and Sullom Voe is one of the most reliable British locations to see them in numbers. Red-throated divers nest on the lochs of the Northmaven peninsula to the west and are frequently seen on the voe surface. Great northern divers appear in late autumn and winter.

Otters use the voe edges extensively. The kelp at the voe margins is rich in the small fish that form most of the Shetland otter's marine diet — butterfish and eelpout in particular. The northern sections of the voe, away from the tanker approaches, give the quietest conditions for wildlife observation. Low water exposes the rocky shelves most effectively; a systematic walk of the voe margins at neap low tide is the most productive approach. Mornings are quieter than afternoons; approach the shoreline from downwind where the terrain allows.

The road north from Brae through the Delting peninsula gives access to the east shore of the voe. Brae is the service community for the oil terminal — a functional village with a leisure centre, supermarket, and accommodation that serves both the oil industry and visiting hill walkers. The village of Toft at the northern end of the Mainland is the ferry point for the crossing to Ulsta on Yell, the middle island of the north Shetland chain; the crossing takes 20 minutes and runs frequently.

Small-boat fishing in the voe is most productive for saithe (coalfish), pollock, and mackerel from summer onward. The entrance area in the deeper water holds ling and cod in autumn and winter on pirks and rubber eels. The voe's sheltered water makes it navigable in most weather conditions that would close the exposed north coast. The large tankers in the southern section create wash and wake hazards; small craft must stay well clear of tanker movements. The Shetland port authority publishes tanker arrival and departure schedules that small-boat users should check before setting out.
