Loading or discharging is not to commence until both, the Terminal Superintendent and officer in charge of tank vessel are satisfied that tank vessel is properly moored and all connections are properly made. At all times when a tank vessel is lying at a wharf, it shall have lines of such length and tightness as to prevent a surge of the vessel from placing stress on the hose.
After inspection has been completed by ship’s officer and terminal representative, proper connections have been made, an effective means of communication has been established, and the vessel is in all respects ready, the transfer of cargo shall be started at a low rate. After operating conditions have been checked and found satisfactory, the terminal representative or ship’s officer may be notified to proceed at a safe rate. When pressure is being built up on hose, joints shall be carefully watched for leaks. Pumping pressure shall not exceed allowable pressure on hose.
When transferring liquefied petroleum gases, flammable liquids, combustible liquids, or products, all hatch covers shall be closed. Ullage plugs shall only be removed from such tanks as are being loaded or discharged. All such ullage plugs removed shall be replaced with approved flame screen. Such ullage screen covers shall be in place while transferring when not being used to take samples, check tanks, or when topping off. Unless the vessel is gas-free, tank tops and ullage plugs of tank vessels shall be closed while any towboat or other vessel is alongside and shall not be opened until any such towboat or vessel has left the tank and there is no longer any danger of sparks or other sources of ignition therefrom.
1. When two or more ships are moored at adjacent berths at a terminal and a hazardous vapor condition develops at any one of these ships, all transfer operations involving all ships shall be stopped and all sources of ignition such as smoking, use of matches, lighters, and open flame (except boiler fires) shall be eliminated on all ships.
2. The Master or responsible officer of any vessel which is transferring ballast, bunkering, standing by or lying at the wharf of any marine oil terminal shall prohibit smoking, the use of matches, open flame devices, and arcing or heat-producing electrical appliances on all open decks of said vessel and no person shall smoke or use any such device or appliance. The Terminal Superintendent shall notify such officer of these requirements.
