Enviro Moorings......

Enviro Mooring

We install the Enviro Mooring System, which is a proven and tested mooring system. This system incorporates a Helix Anchor, Rope / Elastic Rode, and normal mooring tackle. The Anchors have been designed for easy installation and longevity in the marine environment. The galvanised helix have been engineer designed and tested, and full install instructions implemented as part of the procedure. One of these anchors can outperform a 10 tonne  concrete block.

Helix Anchors

Helix anchors were first described in an engineering paper in 1848. They have been used in marine environments since the 1800’s, with initial uses in lighthouse foundations. We install the Galvanised Enviro Mooring Helix Anchor as a mooring anchor for any size vessel. One anchor can easily hold a boat up to 12 metres, and by stiffening up the top of the shaft, or adding extra anchors, any size vessel is possible. 

Mooring Rode

Chains dragging on the sea bed damage the marine environment, and the sand or grit picked up, speeds up the wearing of the tackle. By floating above the sea bed, the Enviro Mooring lasts longer, and does not damage the sea bed. All moorings need a shock absorber to take up the action of waves and swell. The Enviro Mooring Rode has elastic in its’ centre, which provides the comfortable dampening your boat needs. An added safety feature is the 32 mm rope is certified to over 15 tonne breaking strain.

Drilling in Anchors

Drilling in the anchor is able to be completed underwater or from the barge. This means we can install in potentially any depth of water, and we are not restricted by the distance our drill can reach from the boat. As the anchor drills into the sea bed, it starts to gather some resistance. This resistance is measured by a gauge on the drill, and lets us know when it is installed deep enough.

Small Helix Anchors

If you are out of our area, or just want to anchor a small dock these anchors are able to be installed by hand. Slip the pole in the top, and turn around the anchor, and watch it drive itself in. Lengths of 1.2 and 1.5 metres are available, and can hold a small boat, or plastic dock in place. We have also sold these anchors to some Aqua parks.

Surface Buoys

At the top of your mooring will be a floatation buoy. This should always be foam filled, in case it is struck, and develops a crack. The buoy holds your mooring tackle off the bottom, and marks your position. We can fit any buoy to the Enviro Mooring System, and mark the buoy permanently with your designated mooring number.

How We Test Our Moorings

Since 2013 we have been testing and improving the components of our moorings, as well as streamlining the fabrication and installation process, to ensure you get a reliable product to moor your vessel. See some test information below.

Our Mooring Warranty

For any mooring we install, or service, we will give you a formatted inspection report. We warranty the work we perform on moorings for 12 months from the inspection. This is limited to the materials we install or replace during our work. Full details will be in your mooring inspection report. 

Testing the Enviro Mooring Anchors

To test our anchors, in 2013 we installed 8 mooring anchors on the Gold Coast Australia, and tested them to GBRMPA specifications. This was the best test requirement we could find at the time, and we tested right up to a highest category, a D class mooring for up to 20m vessels.

Engineer Design

As part of our testing, we took Engineers out on the barge, to monitor the work, and the testing of the moorings. After the testing, they drew us up install drawings, and materials requirements from top to bottom. We have also revisited the design a couple of times, to improve installation and future maintenance.

Destructive Testing

Our mooring ropes are tested to destruction whenever we make changes to the design, or change manufacturers. The mooring is laid out on a test bed, and pulled until it breaks. The latest Destructive Test was carried out in 2020 to over 8 metric tonne pull.

How We Test The Anchors

To know how much load is applied to our anchors during testing, we use a calibrated test load cell. We carry out this test on site, in the water, in mud and sand locations. The load cell is secured to our mooring tackle, to put everything to a real test.

Anchors For Testing

Our anchors are tested, the same way we install them on site. We use a hydraulic drill to screw the anchor into place, and read the torque on the drill. This way we know how much resistance is applied to the helix discs on  our anchor.

Destructive Testing

This is the test bed our mooring ropes have been tested on in Brisbane, Australia. The press pulls on each end of the rope until it breaks, and the calibrated gauge reads out the destruction load. 

Download a Sample Mooring Report

You can download an example of one of our mooring reports generated from our app by our commercial divers.  The report is generated for traditional concrete moorings, and environmentally friendly moorings. 

Older Conventional Mooring Blocks

Do you still have an older conventional mooring with a block and chain? We first started installing conventional block and chain moorings, and we still inspect those too. Contact us for an inspection.
