B.E.A.R. MkIII System Overview Step by Step Operaon 1. Operaon of the BEAR begins with the selecon of a barge on the tug/portable touchscreen control panel. 2. Once a barge emergency anchor has been selected to drop, a wireless signal is sent to the BEAR unit to inialise the drop. 3. The wireless signal is processed by the control electronics which then sends an ‘operate’ signal to the electronic release module. 4. The dual electronic release units then acvate, cung the restraint line which supports the anchor shank. 5. The anchor shank drops over the edge of the barge, its momentum pulling the rest of the anchor out of its seang. 1. 2.

The BEAR system consists of two primary elements: the Tug Release Unit (TRU) and the Barge Emergency Anchor Release (BEAR) structure. In turn, the anchor release structure consists of the anchor, supporng frame, electronic control systems (including baeries, solar charging panels and antenna) and electronic release system. In addion to controlling the release signal for the anchor, the control electronics provide feedback of the baery voltages, charging current, radio link and presence of the anchor to the TRU Power on the barge is supplied by three 12 V sealed, deep cycle baeries, which are charged during operaon by dual 40 W solar panels and a 55 W vercal axis wind turbine (VAWT). A portable TRU control panel is also available which allows the anchor release to be acvated from rescue craſt or even from land should the BEAR be in range.
