Note: An 1839 billhead shows the name as Acramans, Morgan & Compy.
The Acraman family were involved in a variety of businesses. Their first foundry was at Bathurst Basin, Bristol. In 1829 they opened the 'Bristol Iron Works' in nearby St Phillips. They had a shipyard in Bedminster, Bristol. Acramans, Morgan & Co went bankrupt in 1842. Prior to becoming Acramans, Morgan & Co., the business was called D., E. and A. Acraman, and then W. D. and W. E. Acraman 
1839 'The spirited house of the Messrs. Acraman are about to enlarge the engineering branch of their trade, already very extensive and of high repute. They have taken into partnership Thomas Holroyd, Esq., late of the firm of Ferguson, Brothers, and Co., of Calcutta, and William Morgan, Esq., of London, Engineer ; and the designation of the firm of this particular department will, in future, be "Acraman, Morgan, and Co." Mr. Morgan is a gentleman of known experience, and under his able direction the energies of the concern are, we understand, about to be directed to the manufacture, with other machinery, of the most powerful engines, as well as for marine as for railroad purposes. They have also, we have heard, taken the ground beyond Cllft-house, directly facing the course of the river,which they intend as a yard for the building of iron steam ships. Employment will thus be created for a great number of hands. We cordlally wish the concern all success— Bristol Journal.'

Acraman's had a yard built in St Philip's Marsh near the Feeder Canal in 1839, where they built chain-propelled floating bridges for the Gosport-Portsmouth crossing which were too wide to pass through the floating harbour. The next year Acraman's opened a second more expansive yard in Bedminster, a well equipped yard which built a number of early steam ships. The first saw occasional shipbuilding until 1874, but the second passed to John Payne Ltd in 1862 and as the Vauxhall Yard launched dozens of small vessels directly into the New Cut, until they closed in 1925.
The precise location of the St Philip's Marsh yard has not been identified, but reference to the 1902 O.S. map shows that the Feeder Canal joins the River Avon near the bridge over the River Avon just south of Temple Meads Station.
The Vauxhall Yard is clearly shown on the 1902 O.S. map. It was on the south bank of the River Avon ('New Cut'), close to Clift House Tannery and Clift House Hospital. On the opposite bank was Underfall Yard on a narrow piece of land separating the Avon from the Floating Harbour's Baltic Wharf. The site is now occupied by Bristol Metal Spraying and Protective Coatings Ltd (and possibly Thomas Ware and Sons (Tanners)?). No evidence of the slipway is visible (see photo).
The slipway is visible on the right hand (southern) bank of the River Avon in a 1929 aerial photograph of Cumberland Basin. See detail from photo, above. Underfall Yard is on the opposite (northern) side of the river
