B.E.A.R. MkIIISystem Overview
Step by Step Operation1. Operation of the BEAR begins with the
selection 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 initialise 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
activate, cutting 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 seating.

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, supporting frame, electronic control
systems (including batteries, solar charging panels
and antenna) and electronic release system.
In addition to controlling the release signal for the
anchor, the control electronics provide feedback
of the battery 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 batteries, which are charged during operation
by dual 40 W solar panels and a 55 W vertical axis
wind turbine (VAWT).
A portable TRU control panel is also available
which allows the anchor release to be activated
from rescue craft or even from land should the
BEAR be in range.
