The Draupner wave, a single giant wave measured on New Year's Day 1995, finally confirmed the existence of freak waves, which had previously been considered near-mythical.

Close-up of the event, taken from Paul Taylor's paper.

The Draupner wave is the name of the first rogue wave to be detected by a measuring instrument, occurring at the Draupner oil platform in the North Sea off the coast of Norway on January 1, 1995. Rogue waves, also known as freak waves, monster waves or extreme waves, are relatively large and spontaneous Ocean surface waves that are a threat In the Physical sciences Quality assurance, and Engineering, Measurement is the activity of obtaining and comparing physical quantities An oil platform or oil rig is a large structure used to house workers and machinery needed to drill and/or extract oil and Natural gas through wells The North Sea is a marginal, Epeiric sea of the Atlantic Ocean on the European Continental shelf. Norway ( Norwegian: Norge ( Bokmål) or Noreg ( Nynorsk) officially the Kingdom of Norway, is a Constitutional New Year See also New Year The Ancient Romans began their consular year on January 1st since 153 BC Year 1995 ( MCMXCV) was a Common year starting on Sunday. Events of 1995 Prior to this measurement, such freak waves were known to exist only through anecdotal evidence provided by those who had encountered them at sea. The expression anecdotal evidence has two quite distinct meanings

Minor damage was inflicted on the platform during this event, confirming the validity of the reading made by a downwards-pointing laser sensor. In an area with significant wave height of approximately 12m, a freak wave with a maximum wave height of 25. In Physical oceanography, significant wave height, also known as SWH, or H s, is the average Wave height ( trough 6m occurred (peak elevation was 18. 5 m). Engineer Paul Taylor estimated the Draupner wave was a one in 200,000 wave.
