2400 Plastic Navigation Buoy
The 2400mm plastic navigation buoy is the next step up in terms of capabilities and potential applications. Designed for less sheltered environments the 2400 is perfectly suited to channel marking in large water courses and open harbours. The buoy has also been used extensively for aquaculture applications, specifically as a Fish Aggregation Device for Tuna. This necessitates mooring in depths of up to 800 metres and several kilometres from the shoreline. As with the 1.75m and 2m versions, the 2.4m buoy is constructed from two rotationally moulded float collars fixed around a central galvanised steel core which also forms the dampening skirt, lifting and mooring eyes. In common with the smaller buoys in the range, the 2400 has the same day mark, service exchange tower and Echomax 230 radar reflector giving a peak RCS of 24m2.
|Overall height mm (typical)||4560|
|Overall weight Kgs||610|
|Focal Plane (FP) in mm (typical)||3000|
|FP with 800mm SET ext (typical)||3800|
|Reserve Buoyancy (sealed) weight Kgs||2487|
|Waterline above datum mm (typical)||340|
|Chain size mm (typical)||32/38|
|Mooring weight Kgs (typical)||2300|
|Depth guide||10-40 Mtrs|
Typical chain length 2 to 3 times depth in most circumstances.
The steel core of the EM buoys is the hub to which the float collars, day mark and lifting and mooring eyes are attached. Made from grade 40 mild steel. Galvanised to BSE ISO 1461-1999.
Two rotationally moulded, specially formulated extra high UV stabilised polyethylene. Foam filled with marine grade safety approved foam. These collars can be replaced either individually or as a set if damaged through a collision. This operation can be carried out without removing the buoy from its mooring.
Rotationally moulded and specially formulated extra high UV stabilised polyethylene. Aluminium safety rail attached to outside of day mark. Secured to steel core by 8 x M12 316 stainless steel fixings. If required graphics can be moulded into this component.
Service Exchange Tower (SET)
Rotationally moulded specially formulated extra high UV stabilised polyethylene, it has the capacity to take one or two 200 A/h batteries and a junction box (to IP67 rated). Plugs are all Bulgin Buccaneer 400 mini series IP67 rated. If required graphics can be moulded into this component.
Any suitable preferred manufacturer compatible lantern can be fitted.
SET Optional Extras
Charging system: One x 60A/h or 100A/h gel battery, up to four solar panels, one regulator housed in IP67 rated box secured to battery mounting plate. Plugs are all Bulgin Buccaneer 400 mini series IP67 rated.
Non Lateral Buoys
The Echomax radar reflector is fitted top of the SET.
Supplied with Echomax 230 radar reflector in top mark.
Lateral buoys only: Rotationally moulded and specially formulated extra high UV stabilised polyethylene. The Echomax 230 radar reflector is moulded in. The radar reflector gives a peak RCS of up to 24m2.
Two coats of ZINGA on steel core substantially increases service life.
To achieve a moored float height of 340mm (i.e. 50% of the float collar height at high tide,) the floated mooring weight at high tide should be approximately 50% of the reserve buoyancy.
