Volume Twelve - Pre-Victorian to the Present Day - further aspects - Petroleum-Storage Installations at Avonmouth and at Cardiff [1890] . . . .

The tanks are in all respects similar to those at Avonmouth, and are fitted with gauge-glasses and jointed internal feed-pipes, &c. They stand upon a concrete foundation about 3 feet thick, resting on gravel. The surface of the foundations in their vicinity is finished with a cement-rendered floor, proper facilities being provided for collecting any leakage of oil.

The emptying pipe is of cast-iron, 4 inches in diameter, and is laid from the bottom of the tanks to the filling-house (Fig. 22, Plate 8). An auxiliary feed-pipe is being laid with branches into the tanks, and a portable oil-pump made by the East Ferry Engineering Company, capable of delivering 120 tons per hour, will be connected with it so as to supplement the ship's pumps and discharge the vessel in half the time.

After discharging, the ships receive their coal-supply without changing their berths. A new wharf is being constructed in a more convenient position.
