Background
The Draupner platform rig, located in the Norwegian North Sea and 16/11 160 km (99 mi) offshore from Norway, was built to withstand a calculated 1-in-10,000-years wave with a predicted height of 20 m (64 ft) and was fitted with state-of-the-art sensors, including a laser rangefinder wave recorder on the platform's underside. At 3 pm on 1 January 1995, the device recorded a rogue wave with a maximum wave height of 25.6 m (84 ft). Peak elevation above still water level was 18.5 m (61 ft). The reading was confirmed by the other sensors. The platform sustained minor damage in the event. In the area, the SWH at the time was about 12 m (39 ft), so the Draupner wave was more than twice as tall and steep as its neighbors, with characteristics that fell outside any known wave model. The wave caused enormous interest in the scientific community.
Discovery
The wave itself was first detected on 1 January 1995 by a downward-pointing laser beam located on the Draupner S platform.

"Draupner E had only been operating in the North Sea for around half a year, when a huge wave struck the platform like a hammer. When we first saw the data, we were convinced it had to be a technological error," says Per Sparrevik. He is the head of the underwater technology, instrumentation, and monitoring at the Norwegian NGI ... but the data were not wrong. When NGI looked over the measurements and calculated the effect of the wave that had hit the platform, the conclusion was clear: The wave that struck the unmanned platform Draupner E on 1 January 1995 was indeed extreme.
