The engine room onboard Steamship Storskär

Steamship Storskär's oil fired scotch fire tube boiler's three pressure jet atomized burners.

The top of the Steamships triple expansion steam engine. The high pressure slide-valve is a piston-valve and the intermediat- and low pressure slide-valves are D slide-valves.

Stephenson's link-motion

Each slide valve is equipped with two eccentrics, one for ahead and another for astern. By shifting the position of a quadrant you can get one or the other of the eccentric rods to operate the slide valve rod. A steamer with Stephenson's link motion have the slide valves placed at the engines ends and/or between the cylinders and therefore the engine is longer than if it had had horizontal eccentric rods.

Stephenson's link-motion
The eccentric rods and the quadrant are visible on the picture as well as the lever for adjusting the position of the quadrant.

Cooling water pump driven by a singel cylinder steam engine.
Note that the Steamship Storskär uses the old code of colors on her pipes;
red for steam,
yellow for condensate,
green for sea water,
and blue for fresh water.

A new boiler from Novikat Oy was installed in 1999
