A spar buoy is a floating lit navigational aid which has an upper tower and subsea hull, floating vertically to provide a precision position for the mariner. It is anchored to a concrete block on the seabed by a small number of large chain links.
Spar buoys have a high positioning accuracy and provide the smallest orbit – thereby maximizing the width of dredged shipping channels. Spar buoys have lower installation costs when compared with fixed structures as well as easier installation and can be re-positioned to suit future needs.
Long term performance of Spar Buoys is exceptional, therefore achieving very low maintenance costs. Suitable for major Shipping channels including cyclonic areas.
