Sea impact (English: seawash ) describes the effects caused on the deck of ships or floating structures as well as damage caused by unbroken, massive water acting on the deck (as opposed to splash water). The unbroken arriving on deck seamanship water is also blue water or green water (English: green water ) called. Although sea lurching is the result of blue water in the strict sense of the word, both terms are often used synonymously.

details

Blue water strike on deck can be caused by a number of causes. Possible causes are, for example:

  • Heavy weather,
  • Interactions between wind and electricity,
  • and undercut the fore section
    • too high speed,
    • wrong trim or
    • lack of buoyancy.

Encounters with monster waves are also particularly well-known, albeit rare . In such cases, uninterrupted exposure to water triggers high pressure loads on parts of the ship's structure and on any deck cargo. Slamming can also cause damage to the floor slabs if the fore section hits hard .
