Offshore wind farm substation and turbine at dusk with pastel pink and blue sky, North Sea.

Offshore substation platform viewed from vessel deck at dusk, wind turbines in background, North Sea.

These four images were shot during a calm evening offshore, iPhone in hand from the vessel deck. The conditions were unusually settled: flat sea, no wind to speak of, and a sky that shifted from pale blue through pink as the sun dropped toward the horizon.

The substation is the high-voltage hub of the wind farm, converting the AC output of the turbine array and stepping it up for transmission to shore via the export cable. It operates continuously, unmanned for the most part, with access by CTV or helicopter for maintenance and inspection visits.

The evening light gave the steelwork a quality you don't often see in industrial photography. The structure is functional to its core, but in conditions like this it photographs well.
