The only reason I know about this is my buddy works for GE on the control systems on these ships. I'm always picking his brain on the azipod technology which is what he does.
Yea - that's why I said "catastrophic". There are still single point failures. There are controls that are manual and automatic to switch power over and around the gensets. If something failed on a switching event how much time would it take for the crew to understand and fix?? Meanwhile the...
The propulsion engine require the generators. They will not run without aux electrical power.
Engine cooling, Lube oil, centrifuges, filters, electronics and every pump runs on the Aux generators.
There are no "alternators" on the behemoth......
So if they had a catastrophic loss of electrical...
The cost of money now is cheaper than money later - always.
There is a lot of angst in the current administration to get into investments (unrealized capital gains) and savings to fund the un-fundable. The last several administrations and congress' have grossly overspent with the current...
I think a bench test will only look for direct shorted diodes. An operating generator will reveal diodes that are actively failing. Remember a diode has a breakdown voltage that is probably greater than what a DVM/multimeter provides.
Self insure isn't an option either - you will require liability ($500K minimum) to be in any marina or for a yard to haul the boat out. We put into a marina for a couple of nights and they required proof of liability insurance.
I looked into just liability and self-insure but no carrier would...
Shorted rectifier diodes are an easy test to find out. With a good DVM (Fluke for example) set it on AC voltage and measure the output at the alternator with everything normally connected and running. If the voltage is greater than 0.1 volts (100 millivolt) AC your alternator's rectifier...
This brings up a good point - The first thing is the dinghy needs to be secure and stable without tie-downs. The tie-downs should not have to hold the dinghy in place rather they should hold the dinghy from moving or dislodging when the boat is moving.
I only have two D-Rings on the swim...
Twenty some-odd years ago my buddy and I stopped by the Garlits museum (which looks like where this pic is) on our way to the Gatornationals. There was no one else in the museum except the Old Man was there. He spent two hours giving us a tour and a ton of stories about the Swamp Rats and how...
It sure looks like there are issues with the field control wire. If you disconnect the field wire does the voltage go to battery voltage and current go to zero? Did you happen to disconnect the existing field and run a separate jumper directly to the battery's positive?
Finally got the fenders back from the sheetmetal folks - they did a great job raising the wheel openings. Hanging the front clip to figure a way to shoehorn the intercoolers. Progress....
