Development
Until the middle of the 20th century flatirons were built with
triple-expansion steam engines.
The largest steam flatirons were more than 1,550
gross register tons. The last steam-powered flatirons were built in the 1950s.

By the middle of the 1940s flatiron motor ships with marine diesel engines were being built.][ The largest motor flatirons were more than 1,870 GRT and more than 2,800 deadweight tons.][

Fleets
Some of Stephenson Clarke and Associates' fleet were flatirons.[ William Cory and Son's fleet included at least one flatiron.] The Gas Light and Coke Company's collier fleet included flatirons to serve its gasworks at Fulham

(later the Central Electricity Authority), North Thames Gas Board and South Eastern Gas Board all inherited flatiron fleets from their predecessor companies. North Thames Gas had one diesel flatiron built in 1949 and the SEGB continued to have diesel flatirons built until 1956.[

Decline
After the middle of the 1960s the need for flatirons started to decline. In 1966 gas suppliers started to convert from coal gas

to North Sea natural gas, so that by the early 1970s coal gas gasworks were being closed and demolished. Secondly the Central Electricity Generating Board reconfigured its generating capacity with small numbers of larger, more modern power stations away from the centre of London, which led to the decommissioning of Battersea A power station in 1975, Fulham Power Station in 1978 and Battersea B Power Station in 1983. By the mid-1980s the need to carry thousands of tons of coal on the Thames above the Pool of London had ceased.
Redundant flatirons were sold to private shipping companies who used them as conventional coasters. By the middle of the 1970s several had ended up with Greek or Cypriot owners. One, the SEGB's MV ''Kingston'' (1956), was renamed ''Tsimention'' in 1971 and survived until 1983 when she was broken up.[
