16-20 Prestart procedures
At switchboard, start one of two ship service generators (155 kW) by following procedures in Chapter 3.
Close generator circuit breaker to provide power to switchboard bus.
On switchboard, make sure circuit breaker P10 is dosed to provide power to anchor winches 1 and 2 and
circuit breaker P11 is closed to provide power to anchor winches 3 and 4.
Electric heaters in winch electric motors and brakes reduce humidity inside
motor/brake housing and extend lives of these motors and brakes. Power is
provided to these heaters from power panel 3 (120 Vac) circuit breaker 11P13.
Make sure power panel 3 circuit breaker 11P13 is dosed to provide power to winch heaters.
Visually check each anchor, exposed cable and connections, fairleader and anchor winch for damage. If
damaged, notify intermediate support maintenance unit of repair requirements. If not operational, modify
anchoring procedures to adjust for nonfunctioning anchor winch.
Using a grease gun with extender, lubricate each winch and fairleader as follows:
Eight grease fittings on fairleader (two on each of four rollers).
Eleven grease fittings on levelwind traveler (two on each of four rollers and three on top of Bare 1
traveler). On barges 2 and 3, traveler has four fittings on top instead of three.
One grease fitting on gear case (outboard) side.
Two grease fittings on brake (inboard) side (one on levelwind release mechanism, one on water
end of cover on levelwind gears).
Three fittings on inside shaft behind the manual/power selector.
Levelwind compound helix shaft and guide bars.
Check oil level in gear motor reduction box (see Figure 16-9).
If unit has been in storage, gear motor reduction box may be full of oil and must be
drained to operating level prior to operation.
Remove breather and oil filler plug near top of gearbox.
Remove gear oil check plug located 4 inches from bottom of gearbox on end of unit. Oil should
be level with bottom of check hole.
If overfull from storage requirements, allow excess oil (about 3 quarts) to run out of check hole
into a container. When oil stops flowing, replace plug. Dispose excess oil into bilge system.
If oil level is lower than bottom of check hole, add oil through breather and oil filler plug on side of
gearbox until oil flows out of check hole. Use nontoxic rust-inhibiting worm gear oil, AGMA No. 7.
Replace both plugs.
Check breather plug on side near top of gear motor reduction box: Inner portion of plug must be
screwed out to uncover breather holes. Make sure breather holes are not covered with post.
