A steam/sail ship being unloaded at ICIs Billingham Wharf.
This is Bamletts Wharf – still operational but looking somewhat different nowadays. Bob”s comment above refers to Billingham Oil Jetty which was and is the closest berth to Newport Bridge, on the North bank of the River Tees. Then came Billingham Reach Jetty, now closed but still standing in a derelict state. Between this and Bamletts Wharf was North Tees Power Station and its wharf. Bamletts, it definitely is. The shipyard is in close proximity and the building on the left was known as the pumphouse and was demolished relatively recently, as a guess within the last 15 years. Although the jetty continues in front of the pumphouse, in my experience, stretching back 30 years, this section was never used for berthing ships, depth of water alongside being insufficient. The “dredged box” within which ships are intended to be berthed in safety is roughly in line with the stern of the sailing vessel – the visual mark onshore being the slight kink and change in direction of the berth frontage which can be seen in the photgragh. This can be detected and seen just forward of the second mooring bollard, forward of the rail trucks.
Loading Nitrates, via gantry and over-head rope-way buckets at Billingham Reach not Bamletts ( liquid-filling, petroleum,phenol and later plastic ) which was nearer Newport Bridge. The empty staging and two cranes of Furness shipyard in the right background would put this in the Depression years of the 1930s
Its not a steamship, but a pure 3 masted ship rigged sailing vessel. It looks like its one of the later iron or steel hulled sailing ships that were still being built into the early 20th century. It carries split topsails and topgallant sails which, again, was a feature used in later years on sailing ships when crew numbers were reduced somewhat. Such vessels were still regular traders into the 1930″s, and some survived in British waters into the 1950s, sometimes with much reduced rigs.
