I found the Power history article very interesting. I thought it worthwhile to refer to my letter in the 44 club magazine 142 in 2014 (see below) to augment the article. This concentrated on the Medway Oil and Storage Co's - MOSCO - difficulty when purchasing oil from post revolutionary Russia which is covered by the main article. I missed the point that the three people in the Power advertisement are the party leaders for the 1929 general election, namely Lloyd-George, Baldwin and MacDonald.
I also attach a copy of the notice in the Times on 17th July 1928 submitted by MOSCO announcing they will pay 5% of the cost of the oil to the dispossessed share holders of Russian oil wells.
Also attached (see header photograph), is a 1920s photograph showing the MOSCO development on the Isle of Grain, the refinery is in the background. The tanks to right are Admiralty tanks which were also incorporated into the BP 1955 refinery.
The MOSCO site is still operational with new tankage which stores aviation fuel, pipelined to Heathrow and Gatwick Airports. (There was more information on this in the 44 club article on pipelines 154 - 2017)
The 1960s article mentions Charlton which was a major Power Depot on the Thames. This became a SMBP AD depot, still fed by barge. In the early 1970s, there was a lot of damage to tankage and yard. The old Power tanks were underground and SMBP built additional tankage above ground. All loadings of road tankers were from the underground tanks which were kept filled from the above ground tanks which were replenished by barge. There was a strike which halted all barge traffic and eventually the under ground tanks began to be emptied. The result was that these tanks became buoyant (there was a lot of water underground) and they burst through the concrete causing significant damage.
