On B&W engines upto the MC series with individual (Bosch type) fuel pumps a fuel rack turns the plunger inside the barrel based on the speed/fuel setting. The racks of the cylinders are connected to a common fuel ‘rail’ or shaft. Rotation of this fuel rail is by the governor or electric actuator. Not uncommon that the racks get stiff and manifests in slow or sluggish motion.
Very rare in Sulzer engines (upto the RTA series) as the ‘rack’ is only controlling a light weight static valve in the fuel pump.
In this case, it looks like the fuel rail was stuck or frozen in position. Strange for a Sulzer engine as governor failure would put the rack to zero. Maybe the B altic shipping info is incorrect.
PS: In Hogsnort experience they were probably 1 rev away from the ‘Overspeed trip’ of the main engine that would actuate the same shut down device as the ‘E-Stop’ to stop the engine.
Absolutely nothing wrong in using the e-stop if the Master/Pilot decides to use it at anytime. And nothing wrong in testing - you just need to advise gently …
