When Marathon Oil was shooting a video to celebrate 25 years of production at the Brae Alpha platform 155 miles north-east of Aberdeen, the metal plaque on the helicopter deck commemorating its inauguration was polished to a shine. Six months later, it is a deep, dull red-brown, tarnished by the merciless punishment of the North Sea weather.
The plaque is a vivid illustration of the hardships faced by the personnel and equipment working in Scotland’s offshore industry.
