Fiobuoy...
Concept Overview
 

The Fiobuoy was developed for the principal purpose of removing from the marine environment, surface protrusions which, particularly under night conditions and in other circumstances where there is poor visibility, become hazardous to marine navigation. In addition to its marking function, the device facilitates access to submerged objects at specific times by permitting those objects to be retrieved via its connecting tether, rather than deploying diving personnel.





The process of ascent occurs as a result of positive buoyancy. The release mechanism built into the buoy is an electromechanical device controlled by an onboard computer. The computer is programmed by a hand-held controller which sets the time and date on which the release is to occur. The communication link between the buoy and controller is via an infra-red signal and is security coded. The programming function can also be undertaken by either a standard desktop or laptop computer (ie. a PC).

An Acoustic Command option is now available, where you can trigger the Fiobuoy to surface, or perform diagnostics in the field, using Fiomarine's Acoustic Throught Water Communications system.




The Fiobuoy is constructed with a 'zero leaks' philosophy. Therefore pre-deployment, communication between the terminal and the internal electronics is accomplished via infra-red light actually transmitted through the casing. This method was selected over conventional plugs and sockets which not only leak, but also corrode in a harsh marine environment.

For the same reason, there is no ON/OFF switch on the Fiobuoy. Instead, the Fiobuoy spends most of its serviceable life in what we call 'Sleep' mode. When 'asleep', very little power is consumed, and this allows for very long battery life.

The Fiobuoy is 'awoken' from its sleep mode, in one of four ways:

By the operator wishing to program Time/Date information etc.

When a Release Event is about to take place.

When a 'leak' is detected inside the chamber; or

During its automated, daily diagnosis of battery condition.

After an 'awakening', 'sleep' mode is re-entered automatically following a predetermined period of inaction.
