Release band brake as follows:
Close valve SD3 (Figure 15-9).
Obtain BAND BRAKE PUMP HANDLE from stowed position and insert in pump extension.
While pumping, do not exceed 4,000 psi as shown on BAND BRAKE PRESSURE
Pump until band brake piston comes out of the cylinder and there is a slight clearance between the
band brake lining and brake drum.
Remove pump handle and return to stowed position.
Connect washdown hose to washdown connection on deckhouse top. While retrieving discharge hose,
wash mud and other foreign materials from hose.
As hose is retrieved, remove marker buoys and lines and stow in ROWPU space aft stowage area.
As each layer of hose comes on the reel, make sure transition to the next layer is
smooth. If necessary, operate LEVELWIND control lever to gently form the first
coil of the next layer.
Start retrieving hose by using winch control lever. Operate Levelwind control lever to form first layer of
hose on drum. If necessary, operate Levelwind control lever to gently form the first coil of the second
layer. Then operate lever as needed to form remaining layers. On Barges 2 and 3, also operate disc
brake lever when needed.
When the discharge hose is completely retrieved, tie hose end cap to barge.
Push red STOP button on hydraulic power unit to stop unit, or on hydraulic unit remote control switch.
Open switchboard circuit breaker P12.
15-13.3 Emergency shutdown
15-13.3.1 General. The barge has two emergency shutdown modes. One mode shuts down individual systems such as
the ventilation system or a diesel HP pump, and the other shuts down all barge operating systems.
Both modes are activated by pushing a red button protected by a metal guard. On individual system shutdowns,
either fuel or electrical power is shut off to that system only. On total shutdown, all fuel and electrical power is shut off to
all operating systems.
Seven red system shutdown buttons are located on the ROWPU space starboard bulkhead just aft of the
personnel door. These emergency system shutdown buttons (Figure 3-16) control shore power, ventilation systems,
ROWPU 1 diesel HP pump, ROWPU 2 diesel HP pump, SAG, SSG1, and SSG2.
