Anchor
An anchor is a device, normally made of metal, used to connect a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin "ancora", which itself comes from the Greek ἄγκυρα ("ankura").
Offshore embedded anchors
Embedded anchors such as anchor piles (driven or drilled) are required for situations in which a large holding capacity is required. The design of anchor piles allows for three types of mooring configurations, vertical tethers, andcatenary and semi-taut/taut moorings, which allows for the mooring of different types of offshore structures, such as offshore wind turbines, FPSO, FLNG, etc. An industry example is the Ursa TLP which has been held on-station by 16 anchor piles of 2.4 m in diameter at 147 m long, weighing 380 tonnes each.
