The anchorage of the floating installations, by means of anchoring piles, avoids almost totally the horizontal sliding while the freedom of the vertical movement absorbs the oscillations of the ebbing and rising tide as well as the surge force proper to the environment.

This system is considered as the one which provides the best performance available today. It consists in fixing large tubes vertically in the seabed. Then anchoring rings are slid down and clamped tight to the floating elements.

The pile is a large steel tube whose diameter, thickness and elasticity limit are calculated according the burden and use the installation will have to bear.

The tube is protected by sandblasting to SA-2.5 grade, according to Swedish SIS 055900 norm. After that, a zinc phosphate and epoxy tar treatment is given. Otherwise, a polyethylene layer is applied in hot.

To fix the pile, the lower end is stuck in the seabed at a depth that is calculated keeping into account the composition of the ground and the pressure it will have to bear.

The anchoring ring is made of marine quality aluminium alloy profiles. Its structure bears two lugs on each of its four sides which hold four neoprene rollers that roll over a fixed stainless steel bolt, thus avoiding the damaging of the pile.
