Anchor buoy Modular

Standard modular anchor pendant buoys consist of removable, interchangeable modules with discrete end modules and center modules assembled onto central steelwork and fixed in position with retaining flanges, making up buoys ranging from 1Te to 100Te nett buoyancy. This system allows for the number of center modules to vary according to the net buoyancy required. By adding or subtracting the center modules, buoys can be redeployed on future projects, making them a viable and cost-effective option. Each module is manufactured from a high-performance, low-density rigid PE/EVA foam core, totally encapsulated within polyurethane skin. The polyethylene core is lightweight and closed-cell in nature and will not absorb water even if the skin is punctured. The modules are for surface use only and should not be submerged and subjected to hydrostatic pressure. Nominal skin is colored bright yellow. The skin provides protection for the flotation core against impact damage during deployment and recovery from the vessel. The standard steelwork consists of a central tubular section with an anchor handling cross at one end and a pad eye capable of accepting a shackle at the other. The steelwork is blast cleaned and coal tar epoxy painted. The buoy is assembled by threading the modules onto the central steelwork. Location spigots placed between adjacent modules ensure alignment and prevent rotation during deployment, and the modules are also keyed to the end flanges to further prevent rotation. The end flanges are welded into position, should extra modules be required or removed the weld is ground away and the flange removed.
