1950s Taikoo Dockyard.

The ship alongside at the extreme left is certainly one of Alfred Holt's Blue Funnel Line - the owners of Holt's Wharf, closely connected in business with Butterfield and Swire, who began as their Shanghai Agents in the 1860's. The white passenger ship in the graving dock may well be a P&O vessel, the two smaller vessels on the ways to the right of the picture are harder to identify but since they both have a white line round the hull they may well be CNCo ships.  

May I have permission to reproduce this picture on the ShipsNostalgia forum? I am sure the experts there will be able to identify the ships.

I think this was from IDJ, so hopefully he'll give you an answer shortly. In the meantime, could you just link from that forum to this page?

The Blue Funnel ship is probably the AGAMEMNON of 1929 with its distinctive large foremast probably used for lifting very heavy cargo. It was broken up in Hong Kong in 1963. The P&O ship is the RMS CANTON. At the moment the other vessels have not been identified. IDJ
