Abstract
Buoys are used for mooring purposes and as navigational marks. An embodiment of the invention is be explained in relation to catenary anchor leg mooring (CALM) buoys.Conventional CALM buoys generally have a hull constructed of steel plate by traditional ship building techniques requiring plate benders. Webs, beams and girders are welded inside the hull which is divided into several tanks. The buoy has a central moonpool and a steel turntable. Bending plate, in effect, doubles its cost.A method of constructing a buoy is disclosed, comprising: constructing a framework and affixing flat steel plate to it.
