Mobilis JET 5000 & JET 4000
2.4m diameter navigation buoy

The JET 5000 and JET 4000 are the third largest buoys in the JET series with a 2.4m diameter hull that provides up to 5000Kg of buoyancy. They are suitable for use in offshore, deepwater and large river applications where high visibility is required.

The JET 5000 is available with intermediate tailtube (QI), long tailtube (QL) or flat bottom (FB) options and the JET 4000 is skirted (J). The tailtube options provide a high focal plane whilst the flat bottom is suitable for use in shallow and fast water, particularly where there is a risk of grounding.

The buoys are constructed around a galvanised steel central structure with marine grade aluminium tower and topmark assemblies and medium density polyethylene (MDPE) hull floats. The buoys’ modular design allows for commonality of parts to reduce maintenance, inspection, replacement and spares holding costs.

The buoys are also much lighter and therefore easier to handle than traditional GLA Class 2 steel buoys, and they can be maintained using smaller vessels.
