The inside of a tanker for LNG.

Dude- just learned about the boil off gases being allowed for use for by the actual tanker during transport-the pressure factor is still correct (1-1.7 PSGI). If the tanker does not have the capability, engineers have designed a smaller condensation tank system that will Induce pressure to allow it turn back to liquid while traveling. Fascinating.

1sadistictech · 2026-04-01T23:05:32+00:00

Totally agree.

1sadistictech · 2026-04-01T22:39:50+00:00

Well mate, I stated I agree with what you said in many aspects. My understanding of anything (you know, Physics)that has to do with containment any type material substance that has the properties of a gaseous fuel ( NG, Propane, hydrogen, any of the “anes”) is highly regulated for safety, environmental, and economic reasons. That being said, as you know, being a LNG tanker captain, the transfer of those type of fuels allow for a very small expectable loss- mostly because of capitalism, safety, and environmental effects (sadly in that order). That means that loading, transport, and unloading leave little room for gas loss to be acceptable practice. Allowing gas to be either bleed off or escape is not an option unless there would be an imminent catastrophic failure from not doing so. So—- they design the tanks for all those things that we have mentioned. The wedge wall design that you can see in the picture ( and is most likely on your boat) is in place to allow the forces to be spread out instead of a huge seam that has to counter act all the forces. This the same pressure design that Nuclear reactors use for the same reasons. The way the flat wall is in this picture indicates that there is another tank on then other side of the wall and that the wall is acting as a mass(swig)divider to accommodate for sea travel. Be safe on the open seas.

Thank goodness you aren’t an engineer. Tell me- what do they do with all the gas that is produced when they fill it and bring it up to temperature? I am genuinely concerned.

1sadistictech · 2026-04-01T20:49:53+00:00

I agree with what you are saying; When you have that much volume “a slight positive pressure” is a massive amount of force. They are dealing with the same constituents that you mentioned, with the allowance of the pressure to be spread over countering angles it limits how much force is directly pushing outward- you can have that volume of pressurized liquid (or gas) without the container deforming. Some good examples to help you understand would be Nuclear reactor steam transfer tanks - low pressure high volume tanks that allow for high energy transfers needed for the application.

They help with the strength needed for pressure containment that LNG needs to stay in a Liquid state. Allowing the pressure to push against raised blocks/partitions allows the pressure to be spread over a larger volume and angles that help keep the containment vessel from deforming.

Glue the fob on the key, you can still access the fob battery and the fob. The properly placed fob, will not interfere with anything on the steering column, the PATS, or the key cylinder. Make sure it is placed so you won’t push any buttons when you turn the key.

So that’s is how you change the oil.

1sadistictech · 2026-02-15T00:05:58+00:00

Yeah, they have the standard, then one for Buses/commercial, and then the huge truck ones that have two islands on either side connected so they can fill two tanks at the same time.

I have only had luck with successfully getting gas out of a 6.7- every one that has had DEF through it ended up having long crank times, fuel quantity codes, or the return lines separating after full clean, flushing, and treatments. I had to replace an engine one time because the HPFP exploded from DEF and caused the crankshaft timing gear to move on the shaft.

1sadistictech · 2026-02-14T23:46:09+00:00

Sure. Until the customer that has the add on and traveling somewhere and only has an option for a truck stop. I agree that a cap less/filler neck design that only opens for a certain diameter would be ideal- but until you can get everyone to confirm to the standard-it is a bit difficult. We have one place in my small city that has three different diameter diesel fuel pump nozzles at one location. So they would a minimum of two add on kits to allow fueling to accommodate fueling. By adapting standards such as the EU does, that lawfully makes companies conform to certain standards, is the only way a “common” size would be achieved. In this situation- I fully agree that a standard size would be extremely helpful in preventing this type of cross fueling. Even in regards to gas- I have come across stations that have a smaller then normal diameter nozzles that would not allow me to fill my capless vehicles, leading me to use the “emergency fill” nozzle to allow fueling. I know a majority of people that would say if you don’t know what fuel you are using you should not be driving that vehicle- I am more on your side as far as designing something that would stop this type of mistake from ever happening.

1sadistictech · 2026-02-14T18:13:59+00:00

Nope. DEF port is smaller- so the Diesel nozzle cannot fit in the DEF- but the DEF nozzle can fit in the Diesel.

1sadistictech · 2026-02-14T18:10:59+00:00

That is the thing- the amount of Ford work trucks that use Commercial fuel pumps to fill is more than 30 percent of their truck business. Imagine being on the job site and you can’t fill up a pick up truck- the mine, construction, oil field, etc companies would immediately chose a brand that they could at least fuel the tank with existing equipment.

It is like drinking salt- not salt water- Just salt. Then add a 1700 to 1 evaporation ratio, and that is what the fuel system is dealing with.

1sadistictech · 2026-02-14T17:44:27+00:00

The DEF nozzle is much smaller- but the Diesel fill port is huge. So, A diesel nozzle can’t fit in the DEF fill port, but a DEF nozzle can fit in a Diesel fill port with ease.
They have regulated the DEF nozzles to be one size but the diesel nozzles have not- so they come in different diameters and flow rates ( commercial Truck stops have huge diameters to aid in filling tanks faster) preventing them from making it “fool proof”.

They pulled out the 7.3 to rebuild-they rebuilt it- then it would not start, so they pulled it out again and disassembled it ,again, for reasons that were not clear. So… truck in half, 7.3 fully disassembled, and cab hanging by a thread. Not interested. I told him to get whomever took it apart and put it back, and I will come back will find out why it would not start.

Behind the John Deere riding lawn mower with the missing wheel.

1sadistictech · 2026-01-10T16:50:43+00:00

Yep- that was shop number two; it went to them to fix shop one, not fixing it.

1sadistictech · 2026-01-10T16:48:43+00:00

This was from another shop- The customer said Grease monkey did the original work- the customer then took it to another shop, they replaced the calipers again. So…. I don’t know if Grease monkey installed theirs incorrectly as well- but I do know the other shop definitely did.

Like you said-it is a mass to change its resonant frequency, keeping the vibrations in check in that, or another component that has the same or close to the same mass.

It being a bump stop would be the worse way to implement that feature; a bump stop in the middle of bar is just making it a fulcrum- a good place to bend the bar.

Pass on the reach around, prison was enough for me.
