14-3. Anchor Mooring and Towing Equipment System Description. This system provides a four-point anchoring
system to hold the barge in a fixed offshore position while processing water and for mooring the barge at pierside or to
another vessel. When the seabottom provides firm anchor holding, this system is capable of holding the barge in an
offshore position in a Sea State 3 condition in depths not exceeding 50 feet.
14-3.1. Anchoring system has four electrically powered winches, two on the bow and two on the stem, each with 600 feet
of 1-inch wire rope (cable) hooked to a 1000-pound Danforth type anchor. Winches have both manually and electrically
14-3.2. Each winch is powered by a 10 hp Dresser electric gear motor in a totally enclosed housing specifically designed
for maritime use. For added protection against moisture and corrosion, the motor has an internally mounted 120 V,
single phase electric space heater that will maintain internal temperature between 38 to 55 degrees F depending upon
outside ambient temperature. This motor drives the winch through a drive chain and gears which are running in lubricant
in a sealed housing on the side of the winch frame.
14-3.3. Within the motor housing is a Steams 105 ft-lbs self adjusting electric disc brake. This brake is always on except
when voltage applied to a solenoid depresses the spring and allows the disc and motor to turn freely. For anchor winch
manual operation (without power), this solenoid operated electric brake is manually turned off. This brake has a 120 V,
25-watt space heater to minimize adverse effects of condensation. To work in a saltwater atmosphere, this brake has
naval brass friction discs instead of the usual fiber discs.
14-3.4. Each winch is designed so reeling-in action pulls cable onto the drum underside (bottom-spooling) and is
equipped with a heavy duty levelwind assembly to ensure proper spooling of cable. To assist in spooling cable onto the
nongrooved drum, each winch uses only rightlay cable (wire rope).
14-3.5. Each winch has electrical controls including an ON/OFF switch, an OUT button, an IN button, a STOP button,
and a RESET button. Manual controls provide for engaging/disengaging levelwind mechanism, operating manual drum
brake, and selecting either manual or electrical power for the winch.
