Images of Damage to Engine of The Disperser:

In the fall of 2017, we discovered severe damage to our engine, seacocks, prop shaft, rudder shaft, and skeg. This damage occurred over time, but much of it occurred in a single day when a diver used a compressor on the same electrical circuit we were connected to at Cantamar's marina. The marina had no ground, and all stray current went through our ship because there was no physical ground connected to the marina, and the neutral of the circuit was connected to the ground of our ship.

This damage is catastrophic. I have so far determined that the blower does not close when the mechanism to close it is operated because the flap door in front of the blower is rusted. This prevents the engine from being shut off in case of a runaway situation, which is common on these two-stroke diesel engines. The damage to the interior of the engine is likely similar. But without a full teardown, I cannot know. I cannot take any chances, so a full tear-down of the engine, or at least starting one, is necessary. Further, given the level of oxidative damage to the bell housing, it will require replacement. This damage can be seen in the image titled "Transmission 3".

I have since removed the blower. The engine must be completely torn down and rebuilt because of oxidization in the intake area, which surrounds the cylinders. It is coated with a dangerous mixture of aluminum dust, rust, and oil; which would destroy the engine if I attempted to run it. At this point, there is no reason to believe the engine is even salvageable. This will require a replacement engine. This engine only has 350 hours on it. It was essentially brand new when I bought this ship. This is a severe blow to Disperser as a new engine was a primary benefit of this ship.

This damage was caused by Cantamar, who afterwards, told me they were not required to provide a physical ground to the marina. A physical ground is the most important element of an electrical system in any marina, as the physical ground provides a less resistive path for any stray current to follow, rather than say through a human body, or perhaps a ship's engines and other metal components.
