The Draupner wave, also known as the New Year's wave or Draupner freak wave, was a rogue wave that was the first to be detected by a measuring instrument. The wave, determined to be 25.6 m (84 ft) in height, was recorded on 3 January 1995 at Unit E of the Draupner platform, a gas pipeline support complex located in the North Sea about 160 km (100 miles) southwest from the southern tip of Norway.
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. The rig 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.
Discovery
The wave itself was first detected at around 3:00 p.m. 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). 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.
Records
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.
