Project Description

Mobilis JET 2500

2m Navigation Buoy

Download DataSheet

The JET 2500 is a medium-size buoy with a 1.85m diameter hull that provides 2500Kg of buoyancy. It is particularly suitable for use in nearshore locations where high visibility is required.

The buoy comes in two configurations: the JET 2500 Q, which has a short tailtube, and the JET 2500 FB, which has a flat bottom. The JET 2500 Q can achieve a focal height of up to 3m and provides a very stable platform in deep water and in difficult locations, such as where the bottom shelves.

The JET 2500 FB has a focal height of 2.5m and is used in shallow water where there is a likelihood of grounding. The JET 2500 buoys are  constructed around a galvanised steel central structure with 2 medium density polyethylene (MDPE) hull float sections, and tower and topmark assemblies made from marine grade aluminium. The modular design allows for commonality of parts, therefore reducing maintenance, inspection, replacement and spares holding costs.

The buoys can be raised by any single lifting eye and can be maintained using small vessels making them a cost-effective and lightweight  alternative to traditional GLA Class 3,4 and 5 steel buoys.

The JET 2500 Q PF2.5 is part of the buoy range available to rent from Hydrosphere Rentals Ltd. Click here to visit the website.
