APPENDIX F LOADING OPERATION OF STRAIGHT CARGO GASOLINE INTO BARGES WITH DEEPWELL PUMPS Steps Key Points Preliminary 1. Inspect and read loading orders and sign Declaration of Inspection. Be sure tankerman license is current and covers grade of product to be loaded. Coast Guard (USCG) requires a valid tankerman's license covering grade B and lower to transfer gasoline. 2. Put on life jacket before going on barge. 3. Inspect barge. signs are in place, cargo Insure warning transfer manual, valid USCG Certificate of Inspection, Certificate of Financial Responsibility, and current cargo header test papers are aboard. Confirm that cargo transfer hoses are in date and properly marked. Make sure dock bonding switch (ground) is open. Attach bonding cable or check A. connection if dock has it attached. 6. Check with dock to be sure switch is closed. 5. 239 A. Amount of draft. B. Type of cargo. C. Make sure tankerman orders are the same as dock. D. Tankerman certified to transfer cargo to be loaded. A. Personal vessel safety . A. Confirm vessel is certified to carry cargo to be loaded. B. Compliance with applicable laws. To prevent static electricity by grounding the barge. B. Attach to loading header. A. This assures the ground and keeps sparking off the vessel.
240 Steps 7. Check the barge. 8. Close main hatches. A. 9. Inspect fire screen. A. 10. Place drip pans under loading A. header. Startup 1. Hook hose to loading header. A. Ensure good gaskets. B. Use at least six good nuts and bolts. C. Use spark proof wrench. D. Use stagger method to tighten the bolts on the flange to ensure even tension on all parts of the flange--top to bottom, side to side; go back over two or three times before tightening completely A. Tighten clockwise--hand tight. B. Install blind on end with good gasket and six bolts. C. No pollution. A. Discharge valve from pump. Clockwise. A. Located under main load line. A. Located on top of dome on each compartment. 2. Close valve on opposite end of header and position drip pan correctly. 3. Close pump valve. 4. Open loading valve. 5. Open all compartment valves that will be loaded. Key Points A. Have good bow, stern, and midship lines. B. Visually walk barge checking for holes or cracks. Inspect each compartment by opening main hatch. Check cargo bottom--confirm previous cargo bottoms if available. Close and dog them down. Open and inspect fire screen in the small ullage opening of the cover. B. Leave open to vent barge. C. Ensure a good screen or replace if defective. D. Never load overhead through this opening. No pollution.
241 steps 6. Open header valve where hose is connected. 7. Give dock man the OK to start loading. Intermediate 1. Check each compartment to see if product is loading. 2. Insure the barge is loading level (side to side). Make continual visual inspec- tion for oil slick--to prevent oil pollution. If slick appears, shut dock down and notify USGC. 4. Make continual visual check of each compartment during entire loading operation. 5. Continual check on mooring lines. Key Points A. Watch for leaks at header. B. If no leaks, continue. C. If leak develops: 1. Minor leak--i.e., small drips--attempt to tighten bolts again with pumps running. 2. Major leak--notify dock to STOP their pumps. NOTE!! DO NOT attempt to close valve against the pump at any time. In case of major leak, tighten bolts; if this doesn't stop leak, put in new gasket and start over. 3. If spill, notify USCG and dock. A. Life screen--look in compartment. A. End to end unevenness is acceptable. This assists in topping off or trim operation. B. Check draft marks on each side of the stern. A. These indicate oil leaks from small fractures or holes. A. Make sure one compartment isn't loading faster or slower than another. B. Make whatever adjustments are necessary. C. Prevent spill out of dome. A. So barge does not hang up and either break lines or cause unequal draft.
242 Steps Key Points 6. When barge is nearing completion (20 to 25 minutes) notify the dock to stand by to shut down. Shutdown 1. When loaded to draft, start shutting off valves on each compartment from the heavy end forward. 2. Notify dock man to shut off A. pump and close dock valve. Leave header valve open until the hose and header line are blown clear of product either by air or gravity. Close header valve. Final Stage 1. Disconnect hose from header. 2. Place a blank on header. 3. Pick up tools. 4. Notify dock to open bonding switch and remove bonding cable. Wait for dock man or gauger to gauge the barge. 6. Close last compartment valve. 7. Close all ullage holes. 8. Secure all dogs with spark proof wrench. Sign papers and put bill of lading and chemical data card in proper place. 10. Make final visual check of vessel and emergency shutdown system. 9 A. Give yourself plenty of time. A. Use outside draft marks. B. Bring barge to level position. Leave one compartment valve open to drain hose. A. Only after line has been cleared. A. Dock hose is pulled back. A. Eliminate sparking on vessel A. Use good gasket, bolts and nuts . A. No pollution or unsafe conditions exist.
