Type  of Anchor

The anchoring points fixed to the seabed are the critical part of a mooring system for keeping an FPSO on location.  Depending on soil conditions and the required performance, there are various types of anchors that can be selected.

 

·         Drag embedment anchor

The drag embedment anchor has been designed to penetrate into the seabed, either partly of fully. The holding capacity of the drag embedment anchor is generated by the resistance of the soil in front of the anchor. The drag embedment anchor is very well suited for resisting large horizontal loads, but not for large vertical loads although there are some drag embedment anchors available on the market today that can resist significant vertical loads

§         Pile

The pile is a hollow steel pipe that is installed into the seabed by means of a piling hammer or vibrator. The holding capacity of the pile is generated by the friction of the soil along the pile and lateral soil resistance. Generally the pile has to be installed at great depth below seabed to obtain the required holding capacity. The pile is capable of resisting both horizontal and vertical loads
