A new plate going onto Nobska's hull in 1996.
Note the internal frames where the shell plating is missing.
Half a dozen of the drydock's large keelblocks,
on which Nobska rests, are also visible.
Structural members that cross the frames at right angles are
stringers.
Welding inside the hull during 1997.
The welder is attaching new shell plating to the original frames
at the turn of the
bilge.
Note that those old frames are riveted, the rivet heads are
clearly visible.
Reconstructing the stern section, 1997.
With the shell plating gone the deep V floors are exposed.
Above the workers the
sterntube
that houses propshaft stands out.
The keel, resting on the yellowish blocks of the dock,
is at chest level of the person in the foregrond.
In that area the lower parts of the
floors
are missing.
Model of Nobska's engine.
A large photograph of a model of Nobsk'a 4 cylinder .
triple expansion steam engine. In a reciprocating steam engine
each cylinder is connected to the crankshaft twice;
with piston rods that drive the shaft
and twin push rods that slide the steamvalves.
