have a question related to this extraordinary engine.
heard on the "Discovery Channel" that individual cylinders can be shut down for servicing without stopping the engine. What servicing can
that be? Surely the piston is still moving?

It looks like they built it up in the factory and THEN moved it and fitted it to the ship?. I'd like to see the engine hoist that lifted
that.!

The piston can be dissconnected at the crosshead from the looks of it. It means the crank can still turn, but dettaches the piston at the bottom of
it's rod.

Looks like a steelworks being modified there?
RE servicing the engine with the piston wanging up and down, they can probably work on parts of the fuel injection gear and such like. Big flippin
engine though.
Imagine the bang if it put a rod through the side

didn't it do something silly like 10 rpm? you could work on some of those bits while it was running its moving that slowly.

Big slow speed 2 stroke diesels are assembled and tested then dismantled transported to the slip way and re-erected as the ship is built around ithe
engine, most shipyards had licenses for more than one engine so they could build a ship with a Doxford or Sulzer or a B & W according to the
owners specs that particular engine dosen't look that big by marine standards.

South Shields colleged did have may still have the engine that was prototype of both the P and J type Doxford installed in a lab/workshop it used to
be run once or twice a year -- massive single cylinder unit.

A few years back I had an opportunity to go with a river pilot onto a container ship heading into Felixstowe - one of the biggest ships of its type on
the seas.
After taking the lift several floors up to the bridge, I was looking around when I saw a metal plate screwed to the wall. This plate described the
engine.
Just one engine for this massive ship, 8 cylinders, 100 tonnes reciprocating mass. Apparently it used diesel so heavy that it had to be heated before
it could be pumped through the pipes.
Impressive...
What wasn't so good was the fact that the wind was off-shore, and it took 45 minutes to push it the last 5 metres or so to get alongside the
jetty - side thrusters and 2 massive tugs couldn't do it... apparently when full of containers it has more "sail area" than a
square-rigged tea clipper in full sail!
