Rebuild and install Paxman 12YJ engine

Challenge:

A Paxman 12YJ engine, which is used to drive a fire pump, suffered a catastrophic failure during a regular test on the oil platform.  A piston seized causing the connecting rod to snap and smash through the side of the crankcase.  A serious error had occurred during a previous refit of the engine by another vendor.  The engineer had incorrectly fitted the connecting rod assemblies resulting in insufficient oil reaching the top of the pistons.  The operation of the platform was limited as the safety matrix did not allow certain tasks as one of the fire pumps was now offline.  Below you will see the damage caused to the engine.
