GISMAN benefits from more than 30 years of experience in polyethylene buoys, and offers other floating solutions such as articulated beacons.
Open Sea Buoys
- GBM-3000
Our modular buoy GBM-3000 is intended for the beaconing of exposed sites, in open seas or rough areas, with its 3m diameter polyethylene float and an adjustable volume from 7.5 to 12m3. Thanks to its modular design, and various combinations of floats, steel central structures and spars, the GBM-3000 is able to match all site conditions and client’s requirements.

Coastal Buoys
- GB-2600-ECO
- GBM-2500
- GBM-2000
- GBP-1800
With its innovative design, GISMAN buoy GB-2600-ECO can match a wide range of applications. This is a cost effective and environmentally-friendly equipment.

The modular buoy GBM-2500 (Ø2.5m, volume 5.25m3) is intended for the beaconing of semi-exposed sites. The combination of its 3 main elements is custom-made according to site conditions and client requirements.

The modular buoy GBM-2000 (Ø2m, volume 3.1m3) is intended for the beaconing of semi-exposed and sheltered sites. The combination of its 3 main elements is custom-made according to site conditions and client requirements.

The buoy GBP-1800 (Ø1.8m, volume 1.7m3) is made for port beaconing. Entirely made of polyethylene, it is very light and easy to deploy.

Proximity Buoys
- GBP-1500
- GBR-1250
- GBP-900
The buoy GBP-1500 (Ø1.5m, volume 0,7m3) is intended for river beaconing, shallow waters and fast current zones.

The proximity buoy GBR-1250 (Ø1.2m, volume 0.4m3) is intended for river beaconing and fast current areas.

The proximity buoy GBP-900 (Ø0.9m, volume 200L) is intended for the beaconing of sheltered and protected areas.

Articulated Beacons
With a submerged float from 0.8 to 10m3 volume, GISMAN articulated beacons offer a watch swing radius close to 0. This equipment requires low maintenance. Its design is cutom-made for each site conditons and is suitable for mooring depth up to 50m.
