Anchoring Systems

The suite of screw anchor systems available from Marine Services NZ offers the highest holding power‑to‑weight ratio, and are among the most environmentally sensitive anchoring options on the market today.
Once the screw anchor has penetrated the seabed (normally 4 to 6 metres deep), the only visible part of a shaftless screw anchor is the anchor warp rising from the seabed to the surface.
As a client, you inform us of your requirements, and we will select the appropriate anchoring solution for you. A certified structural plan can be provided on request.
There is a range of anchor types and plate sizes to select from, depending on seafloor topography and the specific requirements of your project.
- Shaftless: Available in lengths: 1m, 1.5m, and 2m
- Shafted anchors with helix in variable lengths
- Holding plate sizes: from 150mm to 1500mm diameter with thicknesses ranging from 8mm to 25mm
- Passive Earth Plate anchors and screw piles for swing moorings
- Dual anchor configurations for securing pipelines to the seabed, developed in conjunction with Ocel Consultants of Christchurch
Using Screw Anchors helps to protect the marine life on the seafloor by minimising disturbance to the surrounding seabed during installation.


With the accuracy of the GNSS positioning system on board our purpose built vessels Soundz Image and Soul Commitment, we can ensure the maximizing of the consented space available to the client.
