 The final evolution of ironclad propulsion was the adoption of the triple @-@ expansion steam engine , a further refinement which was first adopted in HMS Sans Pareil , laid down in 1885 and commissioned in 1891 . Many ships also used a forced draught to get additional power from their engines , and this system was widely used until the introduction of the steam turbine in the mid @-@ 1900s ( decade ) .
