Abstract
Et mekanisk dempersystem (20) er oppdaget for en flytende struktur (10). Den flytende strukturen (10) har et rammeverk (21) som bærer et strammesystem (23) og et mekanisk bremse-systeiri (22) som er effektivt koblet til strammesystemet. En lang dei (25) har en nedre ende (32) forankret til sjøbunnen (16) og en ovre ende (34). Strammesystemet holder den lange delens ovre ende (34) fra rammeverket. Strammesystemet, i drift, anvender et forhåndsbestemt strekk på den ovre ende av den lange delen, som friksjonelt varieres av bremsesystemet avhengig av hivbevegelsen på den flytende strukturen, derved brukes tilhørende dempningskrefter derpå.
