Abstract: 

The anchoring systems used to secure many offshore structures conventionally employ multiple drag type anchors and long, heavy chains. By reducing the amount of equipment needed to secure offshore structures, installation, maintenance and labor costs could be reduced. One solution to this problem is to use a single point, vertical lift mooring system utilizing a hydro-jet anchor. Installation of this type of anchor is accomplished by employing a tripod support system that can be retrieved and reused. Test results show that hydro-jet anchors perform best in sandy sediments. The anchors developed have a holding capacity to weight ratio of approximately 25 to one.
