Im a dockside crane driver, so been on a few ships in mine time, lifted a few engine parts on to them, pistons etc, and they are rather huge...i have sometimes thought how the hell do they change the engine if it goes boom, some are stuck right under the bridge's etc, now i know just cut the boat until you can get it out

Also notice thats some crane lifting it out, dont look like much but has a S.W.L of 200ton...
