Offshore mooring anchors

Fendercare Marine provides a range of high holding power anchors for offshore mooring applications with high performance capabilities.

Our heavyweight, high holding power anchors are deployable in a wide spectrum of seabed mediums to support offfshore and deepwater operations, protecting vessels and other offshore floating assets by ensuring their continued safe mooring.

The offshore high holding power anchors can be used with semi submersible rigs, to permanent mooring installations, having a significant holding power to weight ratio.

CMIC high holding power delta anchor (A3-10002)

The CMIC delta anchor is a well established high holding power anchor design approved and certified by all major classification authorities and available in weights from 250kg to in excess of 20,000kg.

In built stabilisation within a wide fluke area, combined with adjustable fluke angles of between 28-50 degrees, enables deployment in a wide spectrum of seabed mediums and has allowed the anchor to become widely accepted within the offshore, dredging and marine civil engineering industries.
