STANDARD OPERATING INSTRUCTIONS NO, 2 MAINTENANCE AND OPERATION INSTRUCTIONS FOR POL FACILITIES PARRY ISLAND DIESEL FUEL LOADING OPERATION 4. The diesel fuel oil is delivered to the POL tank farm by a tanker ship which anchors off shore and connects to a flexible line at the marker buoy. This flexible line, in turn, is - connected to a steel submarine pipe which delivers the diesel fuel oil to dehydrators Nos. 1 and 2 through valve V-2, strainer Sl, pressure regulator V3, and valves V4 and V5. Salt water in the submarine line is drained back into the lagoon through valve V-1. The entrained water is separated and drained off at the dehydrators Nos. 1 and 2 and the diesel oil then goes to deaerator No. 1 through valves V8 and V9 and pilot operated motor valves V6 and V7, where the entrained air is separated and vented to the atmosphere, The diesel fuel then leaves the deaerator and passes through Meter M-1, valves V13, V1, and V15 to the main diesel loading header, and is delivered to the tank loading header through valve V23 and liquid level control valve L-1 and thence through valves V2/ through V28 into tanks 1 through 5 respectively. The diesel fuel is delivered to tanks No. 304 and 305 from the main diesel loading header through valves V38, V39 and V42, and to tanks 153 through 158 through valves V41, V34, V36. During the loading operation valve V1 is opened and valve V2 closed until the excess water has been drained from the submarine line; then valve V1 is 2-3
