Project Description

MOBILIS JET 9000 & JET 8000

3m Diameter Navigation Buoy

Download DataSheet

The JET 9000 and JET 8000, with 3.0m diameter hulls providing up to 9000Kg of buoyancy, are the largest buoys in the JET series. They are  suitable for use in offshore and deepwater locations where a highly visible navigation buoy is required.

Built as an alternative to GLA Class 1 or 2 steel buoys, the JET 9000 and JET 8000 buoys have longer maintenance intervals, is much lighter and easier to handle, and can therefore be maintained using smaller vessels.

The JET 9000 is available with intermediate tailtube (QI) and long tailtube (QL) options and the JET 8000 is skirted (J). The tailtube options provide a high focal plane of up to 6m whilst the skirted version can achieve heights of 4m.

The buoys are all constructed around a galvanised steel central structure and use 4 medium density polyethylene (MDPE) hull floats, with marine grade aluminium tower and topmark assemblies.

The buoys’ modular design allows for commonality of parts, thereby reducing maintenance, inspection, replacement and spares holding costs.

The JET 9000 intermediate tailtube buoy (QI HV-PF4) is part of the buoy range available to rent from Hydrosphere Rentals Ltd. Click here to visit the website.
