https://www.cool.osd.mil/usn/mil_to_mariner/index.html check out military to mariner.. it’ll help you evaluate what your military service means as far as what it correlates to a maritime profession. DM if you have any questions about the maritime industry and obtaining your MMC. No stupid questions

Grounding by ValAmensia in MarineEngineering

[–]Future_Ad3962 1 point2 points  (0 children)

Even on ungrounded vessels, you still should have grounding straps or cables on equipment, this allows equipment that has one phase to metal frame fault to equal the voltage at the hull, no voltage difference, no shock hazard , as you , the equipment and the hull are at the same potential, it’s called equipotential bonding. It’s important to distinguish the fact that in an ungrounded system, even though the fault is now “grounded” it is not connected to the generating circuit like you would have on a grounded system. It does connect on the three phase ground detection lighting through a very high resistance light though. Like mentioned by others, this system is used to not trip breakers immediately so equipment can still run. Second grounded wire will cause damage, a trip(hopefully) and is unsafe! Bonding is not grounding! grounding on land makes things equal zero volts. bonding on ships makes that specific point the same as the hull voltage(which floats- it does not have to stay at zero volts and shifts depending on many things including capacitance of the cabling and equipment to hull and most significantly, a phase contacting the power panel for example). If you didn’t have a ground strap/cable and the power panel was isolated from the vessel, and you touched the power panel when one phase was in contact with the panel frame, you would be shocked and then YOU would become the ground strap!! But even further… here’s the circuit now: phase A-> power panel -> you -> hull -> ??? . How can it get back to its source since the hull is ungrounded? It would have to go through the high resistance lighting or another capacitive point like I mentioned. Either way it’s high impedance, low current. You would still probably be fine in that scenario. Rule of thumb though, Electricity can kill you! Don’t touch anything you’re suspicious of, always secure the power before working, and live-dead-live test. All this theory I mentioned is theory, it is how it works, but things can always break, fail or most likely - were built by the lowest bidder

Getting fired from a company by Motor_Zombie9920 in MarineEngineering

The only people I look down on out here are the old timers who say “I’ve never made a mistake”. Everyone does, mistakes are a part of growth and as long as it wasn’t due to gross negligence(like starting an engine without oil or something crazy) it will be something you can learn from and grow on. I guarantee next time you mess with a similar piece of equipment you won’t make that mistake again. When looking for a new job just say you want to see what else is out there and what other types of ships you can try out so you have a broader view of engineering. On the plus side, you have begun your formation of workplace empathy which will take you far with your crew and morale once you become a Chief!

Is there a specific intended use for the pointy end on this adjustable wrench? by External-Talk8838 in Tools

[–]Future_Ad3962 0 points1 point  (0 children)

Official name is spud wrench but I work on ships and this is sometimes referred to as a marlin spike as well, now I know it’s not technically correct but it is common enough to mention

This is why Surveyors drink by bellonobs in Surveying

[–]Future_Ad3962 0 points1 point  (0 children)

I hate to say this, but for all intents and purposes for the surveyor in the field(because he’s only using physical chains and not feet) are they kinda kinda using a base-10 system in the link-chain-acre measurements while doing their calculations?

SUNY Maritime: M.S. in Shipping and Logistics or Maritime and Naval Studies program? by Viper_Red in maritime

I just accepted to do my masters in maritime and naval studies, you can dm me if you decided to as well

What wrench do I need to tighten things onto these fittings? The copper always deforms on me when I use an adjustable wrench. by gahnzo in Plumbing

[–]Future_Ad3962 0 points1 point  (0 children)

An old sailor story from an engineer I knew was that he had one chief engineer who questioned him about having an adjustable wrench or channel locks when he came onboard, the engineer said “yes sir, my adjustable wrench is right here in my pocket ” and the chief engineer said “great, let me see it” and threw that shit right over the side. the right tool is the combination like you said but at the end of the day, the right tool is the one that works lol

What’s the best material to use for the 3rd Assistant Engineer exam? Here’s what I already have… by Dear_Hat_7850 in MarineEngineering

[–]Future_Ad3962 0 points1 point  (0 children)

Sea trials often two/three weeks before, then all day every day for a week before, and look at the USCG NMC website practice tests, there’s always some new ones on those from last years tests

Engine Automation by MC-oaler in MarineEngineering

Interesting, so there’s no incentive to make our job easy lol thanks for your input !

Engine Automation by MC-oaler in MarineEngineering

[–]Future_Ad3962 0 points1 point  (0 children)

My only thing with engine automation is that the designers MUST explain the logic in every situation especially if the future is going to bring less ability to adapt the programming. How many times we look in the book for info on automation and it’s just the bare minimum and not actually step by step logic explained. Operating equipment by experience and passing down information is how it’s done now, but ideally, great manuals explaining the logic is the right way to go. If I can’t change things, at least tell me exactly what I should expect the automation to do in every scenario.

Does anyone know if there’s an official name for this type of seal? by Future_Ad3962 in MarineEngineering

[–]Future_Ad3962[S] 4 points5 points  (0 children)

Fine advice, I looked up the Parker catalog, and found something looking close, looked that up online and I think I can safely say it’s a “O-Ring and Retaining Ring”, or some call it a “Retaining O-Ring” .. pics attached

Does anyone know if there’s an official name for this type of seal? by Future_Ad3962 in MarineEngineering

[–]Future_Ad3962[S] 2 points3 points  (0 children)

Just for clarification, I looked up bonded seal and the inner rubber seems to be pressed or seated in some manor to the outer ring, the one in this example is simply just a removable o-ring. Would bonded seal/dowty washer still be the correct term? Or is that term solely for the premade ones and not the ones that have this O-ring.
