B.E.A.R. MkIII

System 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.
