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
Anchor piles are typically designed to resist both horizontal and vertical loads. The axial capacity of the pile is generated by friction along the pile-soil interface while the lateral capacity of the pile is generated by lateral soil resistance, whereby the point of rotation is critical to optimising its lateral resistance. As a result, the location of the padeye is placed such that the force from the catenary or taut mooring will result in a moment equilibrium about the point of rotation, mobilising the optimal lateral soil resistance.
