Cubed iron ship tanks were invented by Richard Trevithich in 1808, in partnership with Robert Dickson, and the design was patented that year. The invention was an improvement on the wooden casks or barrel that were in used at the time, as the ship tanks were more secure and their shape was much more economical on storage space. The robust metal tanks were originally made to transport water, but their preserving quality enabled them to transport perishable dry goods such as grain on long voyages, as well as other forms of liquid and solid cargo. The first ship tanks were made from sheets of iron, and later mild steel sheets, with double riveted edges and corners. A round cast iron lid with handle grips was fitted snugly into the top opening, providing an air tight and water tight seal. Brass taps were often fitted into the base. Sailing ships began using the new ship tanks on Australian voyages from around the 1830s, storing ford and water for those on board, and filling them with other cargo. A large number of the ship tanks were repurposed in 1838 for the Victoria Settlement at Port Essington, N.T., as they were able to protect the food, clothing and other stores from termite and insect damage. Other ‘recycled’ ship tanks were cut in half and used as washing tubs or cookers. A 1929 catalogue from Hudson’s Tank Stores advertised square tanks that contained around 600 litres – 160 gallons – which equals internal measurement of 33.25 inches – 84.5 centimetres – per side ship tanks are still made and sold in 1952 by the Globe Tank and Foundry in Wolverhampton, England, which was incorporated in 1922. Today, ship tanks can be seen around Australia. Wilsonson’s Promontory Lightstation has the lid from a ship tank that was used on site for the storage of water. Some have been repurposed as domestic water tanks and dog kennels, others for eucalyptus distilleries. Flagstaff Hill has two ship tanks in it grounds. The Campaspe Port at Echuca, once aa bustling river port, has a ship tank beside the locomotive yard. The lids of ship tanks are collectable items. Richard Trevithick (1771-1833): - Trevithick was born in 1771 in Cornwall, England. He was a famous British engineer and inventor during the Industrial Revolution, known for his invention of first full scale working railway, high pressure steam locomotive, which he demonstrated hauling a railway train in 1804 . He set up a small workshop in 1808 at 72 Fore Street, Limehouse, London, to make iron ship tanks, and this invention was instrumental in replacing the wooden casks formerly used for storage on ships. He was involved with mining technology, iron foundering and ship equipment. Ship tanks changed the way that cargo was transported on ships and other vehicles from the 1830s and were used into the mid-20th century. The ship tanks’ advantages were that they could store more content, lasted longer, were waterproof and airtight, stackable and could be repurposed for many uses other than water, such as fuel, dry goods and domestic cargo. They have even been used aa dog kennels and cookers. Ship tanks were part of the evolving methos to transport water, food and cargo, which changed in 1956 when Malcolm McLean invented the large, rectangular shipping containers that are in use today; they speed up the process of loading on and off the ships, saving time and money. Ship tank: a cubed iron container with an offset hole on one side. The hole has cutouts for securely attaching a lid. This tank is on its side on the ground with the opening facing sideways. The side facing upwards has a wooden bung in a round hole. The ship tank is made from six square, thick iron sheets, rolled and riveted along the edges. The inside has a black sticky coating, possibly bitumen, and a strong creosote odour. There are small remnants of green paint on the outer surface.flagstaff hill, flagstaff hill maritime museum and village, warrnambool, maritime museum, maritime village, great ocean road, shipwreck coast, iron cube, water tank, shipping container, ship tank, ship's tank, ship tanks, marine container, richard trevithich, 1808, robert dickson, water transport, water storage, iron foundry, steel sheets, iron sheets, revets, victoria settlement, port essington, globe tank and foundry, wolverhampton, british engineer, british inventor, wooden casks
