15-13 Shutdown procedures. When shutting down shore discharge operation, coordinate hose retrieval with shore
receiving station. First, blow out drinking water from hose (paragraph 15-13.1). Then, retrieve hose and secure winch
Make sure good communications between barge and shore facility have been
established to coordinate discharge hose retrieval.
15-13.1 Discharge hose pigging (hose blowout)
Discharge hose must be emptied of its water before retrieving hose. Removing
water reduces weight of hose, making it easier to retrieve.
On barge, close valves SD1 and SD2 (Figure 15-7).
On shore, perform the following:
Close valve at shore facility.
Disconnect hose flange from shore facility flange.
Connect PIG receiver to hose flange.
On barge, perform the following:
Open PIG insertion point (Figure 15-7), insert PIG, and reinstall cap.
Connect 25-foot air hose between Compressed Air Station 6 and PIG insertion point air
Open valve SD2.
Make sure compressed air system is operating. Start up and charge receiver if necessary.
When shore end of discharge hose has been disconnected and PIG receiver on shore is ready to
receive PIG, open Compressed Air Station 6 supply valve.
When PIG arrives in PIG receiver on shore, close Compressed Air Station 6 supply valve and
On shore, remove PIG receiver and remove PIG. Return PIG to barge if reusable (not badly worn
Pigging time is about 15 minutes. About 1,500 gallons of water will be discharged
On shore, connect hose end cap to hose flange. Make sure cap is tight to provide watertight
connection. Return PIG receiver to barge and stow.
15-13.2 Discharge hose retrieval (hose in)
Make sure that nobody stands in front of or behind hose reel. Make sure steel
chute is smooth and free of any dents or cuts that could damage hose.
Attach floats to discharge hose end cap.
