Though a mere sailor, I have never heard the term, nor seen anything like the description in terms of what a boat needs.

Based on Spencer's behavior to-date, it would not be a bad bet to assume he made it up.

But really, who cares?

Scientific terminology is not made up !

The flat line has a bow plane , stern plane , port and starboard plane .

I'm sure you will be more familiar with those terms .

So why do ship building plans not show "flat line" in/on plans?

Again if you have a link to diagrams of ship building plans which show such please post in this thread

Thanks

:)

You won't find technical expertise such as this on the mainstream internet !

Mainstream info is for the novices in ship building .

I beg you pardon ?

Didn't you promise me a Rose garden but instead only delivered me manure ?

You won't find technical expertise in rose delivery in a internet science forum

However if you post manure you can expect it to be returned

An interesting comment but unfortunately it does not apply to my posts !

Principle golden rule:

1) The flat line must always be above the water line

It is not my fault your information is outdated !

Interesting and incorrect

I give you

Mighty Servant 2

https://en.m.wikipedia.org/wiki/Mighty_Servant_2

I had the pleasure of assisting this vessel, as the radio operator on the ocean drilling rig, position itself to load the rig on to its deck

Said deck was well below the surface of the water

No golden rule there

The rig was lifted out of the sea and my next duty was to disembark the remaining crew

I was in the last group to leave, the last person was the Toolpusher (the day boss)

Great times

Not my fault your brain is outdated

:)

Wrong context ! You are discussing a drop ship which is not the ship building we were originally discussing .

Where a deck is lowered into the water by design specifics .

The origin of this thread is the Titanic !

A poor design that used lots of rivets that were not tightly fitted as suggested in the build .

A hot rivet would cool down and in essence contract in size leaving possible play in the design .

I suppose it could of been worse though , as a riveted twins towers and poor quality grade steel !

On cooling its contraction in rivet length not diameter that matters. Creating rivet tension, which secures the joint better by friction between plates. And enhances water-tightness. Those shipbuilders weren't stupid.
I recall a doco which pointed to a coal bunker fire prior to sailing, which took a long time to control, that weakened a section of hull right in line with the iceberg hit.
Whether it would have sunk anyway no-one can say for sure.

Not true ! Length and diameter is important . A 19mm ''bolt'' has play in a 20mm hole (example)


In a few of the youtube videos I watched , I didn't see any T plate join welding between panels .

Backs what I said.

???? Is it a habit to spring something never brought up as though someone else had raised it?

Hmm, no!

Just because it says something somewhere , that doesn't make it physically true . Riveting would be better if the plates and the rivets were both equally in a state of heated expansion .

In engineering we heat fixtures to remove stubborn fixings such as a bolt . The surrounding metal expansion allowing the bolt to become more free . Basic scientific thermodynamics .


A (T) fixing is an inner plate that is formed as a T shape . This fixing is placed between two adjoining panels from the interior , the ''leg'' facing outwards .


Then a few welding tacks are done to hold it in place

The leg is then grinded down to a flat finish from the exterior

The weld is then completed in the form of seams

For additional strength depending on requirement , rivets can be added to the over hang T-flap

-T- demo (obvious the T is flush against the plates )

Nonsense. That would achieve nothing useful.

Chalk and cheese. Preferentially heating the metal surrounding a frozen bolt works mainly owing to differential expansion. First hand experience of that. Hot riveting is quite different.

From that bit of ostensibly intimate metal working knowledge it's reasonable to conclude you are a he not she.

That is somewhat a contradictory statement my dear , the law of physics do not differ to agree with ones owns subjective understanding .

A rather sexist statement !

You can assume I am a diversiologist and consultant , that is my scientific background . As a diversiologist I have intricate knowledge of several sciences , this includes design and construction based on quantum ergonomic's .

This only reference I can find on drop ship

Anyway I think I will not Iggy just yet as you have some amusement value

Not much, but some
