All Mobilis data buoys comprise a robust central steel structure with through-hull access for underwater instrumentation and cabling. Buoyancy is provided by multiple-section, rotationally moulded polyethylene (PE) floats, which are bolted around the structure. These floats are UV stabilised to retain their colour within IALA guidelines for in excess of 15 years.
The buoys can be supplied as a hull-only assembly for customers to fit their own towers. Alternatively, Hydrosphere can supply a variety of towers to suit individual requirements.
A range of towers is available depending upon focal heights, payloads and power requirements. Towers are manufactured from marine-grade aluminium and can be fitted with a large range of battery housings, solar panels, sensor rings and top marks.
The modular design of the buoys means they can be tailored to customer requirements, and work can be carried out on components individually during assembly. The result is a range of flexible platforms that can be utilised across a variety of applications whilst remaining easy to handle, transport and maintain.
