1. eva foam filled marine navigation buoys are available in a wide range of sizes, can be supplied in suitcase, modular and non-modular type, and in custom and standard configurations. All are supplied with removable central steelwork configured as per the customer's requirements be it the typical handling crucifix/ padeye arrangement or a through hawse for use with anchor wire rather than chain.
Usually, there are two types of
eva foam filled marine navigation buoys:

Offshore Anchor Pendant Buoy(APB):
Evergreen Suitacase
Offshore Anchor Pendant Buoy(APB) is designed to withstand the rigorous conditions associated with the offshore industry.
Evergreen Suitacase
Offshore Anchor Pendant Buoy(APB) is manufactured from resilient, closed cell polyethene foam. The closed cell structure of the resilient PE foam core menas that the buoy will not absorb water, even if the skin is punctured therefore maintaining buoyancy and functionality.
Designed specifically with large flat surfaces for safe and secure storage onboard anchor handling vessels, Evergreen Suitacase
Offshore Anchor Pendant Buoy(APB) has an enviable reputation for quality and performance.
The table blow shows a range of standard sizes only, other sizes or specific buoyancy / dimensions required are evaluated on application. A variety of steelwork options, e. G. Anchor cross, pad eye, swivels etc. Are available.
Standard colors are orange or yellow but other colors are available on request. Further options are available too.

Modular
Offshore Anchor Pendant Buoy(APB)
Evergreen Modular
Offshore Anchor Pendant Buoy(APB) consists of removable, interchangeable modules with discrete end modules and centre modules assembled onto central steelwork and fixed in position with retaining flange, making up buoys ranging from 1 tonne to 100 tonne nett buoyancy.
This system allows for the number of centre modules to vary according to the nett buoyancy required. By adding or subtracting the centre 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 / PU foam core, totally encapsulated within a polymer skin. The PE / PU core is lightweight and closed cell in nature and will not absorb water even if the skin is punctured.
Nominal skin thickness is 12~14mm and is colored bright yellow / orange. The skin provides protection for the flotation core against impact damage during deployment and recovery from the vessel.
The standard steelwork consists of central tubular section with an anchor handling cross at one end and a pad eye capable of accepting a 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.
