Polyethylene buoys
Polyethylene buoys have been used as maritime Aids to Navigation (AtoN) for almost thirty years.
Their steel equivalents are almost 4 times as heavy, making them difficult to transport – requiring larger vessels and more personnel to manage them.
Whilst their lifetime is longer; the initial cost is some 150% more than polyethylene leading to an overall reduction of 40% in the cost of ownership.
Polyethylene buoys are sustainable and can be re-cycled and repurposed after their service life.
