The Draupner wave, also known as the New Year's wave or Draupner freak wave, was a rare freak wave that was the first to be detected by a measuring instrument.[1][2] The wave, determined to be 25.6 m (84 ft) in height, was recorded on 1 January 1995 at Unit E of the Draupner platform,[3] a gas pipeline support complex located in the North Sea about 160 km (100 miles) southwest from the southern tip of Norway.[4][a]

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.[5]

Accompanying storm

On 31 December, a low pressure system was located over Sweden, with a north-western motion. This system produced large waves over the North Sea, although none would be of significance. Early the next day, a polar low would form over the Norwegian portion of the North Sea, which produced heavy winds that would set up the formation of the Draupner wave.[6]

Discovery

The wave itself was first detected at 15:24 UTC on 1 January 1995 by a downward-pointing laser beam located on the Draupner S platform. The laser beam 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).[7] The reading was confirmed by the other sensors.[8] The platform sustained minor damage in the event.[4][9] 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.[4][8]

Legacy

The platform sustained minor damage in the event.[4][9] 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.[4][8] The wave, one of the largest ever documented in the Atlantic Ocean,[10] helped solidify the initial speculation that rogue waves did naturally occur, and as a result the wave would be heavily studied in the years following the event.[11]

"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.
