The justification for building the Interstate Highway System was for national defense, so assets could be moved around the county more easily. There was never any plan to move the highway system overseas.
Same with the Jones Act ships, AFAIK using Jones Act ships overseas is not a significant part of any military planning.
I think 45s are the largest standard these days but RoRos can handle them easily on trailers. I have seen 53s on the top of low stacks with the ends hanging in the breeze.
Yes, I am aware that 53 foot containers are in use but from what Iāve seen they are loaded on top. Are there mechanical āslotsā that can only hold 53 footers?
Why would they be required when there are twislocks at the 40 foot positions? Except for access issues and lashings I donāt see why they couldnāt be stacked on a hatch cover.
I canāt imagine any guides being made for them since they are relatively rare.
I was responding to @Tellarian who is saying that a container ship that can carry 53 foot containers isnāt militarily useful. I was trying to think of some way that makes sense.
Not to mention that it assumes that JA ships are intended for use overseas.
I canāt see how saying that a 53 footer is not militarily useful makes any sense at all. They carry 60 percent more than a 40 footer and when mounted on a trailer fit on a RoRo very handily.
Well, maybe you could help out here. I work RO/RO and we donāt use either term, we use RT units. Lane meters is a term Iād associate with RO/RO ferries more then deep-sea.
I know container ships have bays, cell guides, Iām not sure what is meant by the term āslotā
Pretty specious no? Why are you dragging militarily useful idea into discussion of the Jones Act - presumably meaning the cabotage part?
But since you are going down this rabbit hole. From the MARAD data:
Of the 99 Jones Act Eligible Vessels (again over 1000 GT, self propelled and oceangoing)
78 are listed as militarily useful and those break down as:
Tankers 46
Containerships 23
RORO 7
General Cargo 2
The MSP applies only to the Non Jone Act eligible ships and no doubt those are the ships that would be called for first in an emergency sealift situation. Iām sure if the situation warranted it the Jones Act Fleet would be called out as needed hence the identification of ships in that fleet as militarily useful. If the DOD took the time to make such designation it would appear they see how they could be of use.
Your reference to the Aloha class spec does nothing to support an argument that older container ships are not militarily useful. The military thinks they are.
Jones Act in terms of cabotage is somewhat effective at ensuring a bare minimum of shipbuilding, ship operating and ship crewing expertise is maintained as a national asset.
The non Jones Act eligible fleet provides ships, crews and operating expertise with specific militarily useful vessels pre-identified and committed (via the MSP) to sealift support when needed. These may be built in foreign yards. But 100% US manning is still required. This does far more for readiness, manning pool and general industry health than a second flag would.
So whatās your beef? This is the system that has evolved in the US. No one says itās right for the rest of the world but Iām not getting why so many people with so little in the game have so much to say about it.
All the ships and crews that serve the import and export requirements of the US that are not US flagged are making money no? They dominate the market I would say. So again what is your beef?
If you donāt think the US needs to have the military it does or to stick its nose in other peoples affairs to the degree it does necessitating the need for sealfit then you only have to run for congress and change things.
Of course it doesnāt make sense! Aloha class spec he linked to says it is ācapableā of carrying 53 footers. The capacity is given in FEUās and notional loading in TEUās. It didnāt say exclusively 53 footers or having special cell guides that I could see. These are like tanker ISO units, flat racks and open tops. They are a specialty item you fit in. If they are on the hatches on top of stacks so what?
The vessel ceases to be militarily useful if it is capable of carrying a 53? Maybe that company had a need for that capability for their trade?
Just a FYI, 48 and 53 foot containers are 8ā-6" in width. The securing twistlock foot print is different is than standard ISO (20ā, 40ā, 45ā) containers which is why you are more likely toi see them on a RO-RO than a containership unless specifically set up to carry those boxes.
The term āslotsā usually just means how many of a particular sized container one can carry. A āspecific slotā would refer to the actual cargo position, i.e., Hold X or Bay Y, Tier Z.
No beef at all, just an observation. The singular nature of some vessels make the difficult to justify, IMHO, to be truly militarily useful in todays world.
Look at Hold five.
Guess it is a tomato / tomaeto thing. Slots are container cells in the rest of the world, and lane metres used on Ro Ros elsewhere for units that exceed the RT units, e.g. project cargo, oversized units.
So your observation is this ship has capability to carry 53 foot containers so it is not militarily useful? That does not seem credible.
Again though the main sealift support will come from the MSP enrolled ships in the Non-Jones Act eligible US Flag fleet. The Phillyship announcement says these are Jones Act container ships.
The system seems to have some depth. Start with the MSP ships then tap JA eligible as needed. Look 3600 TEU capacity is more of a downside than have 53 footers capability. But if the overall required capacity was such wouldnāt a war planner make use of that?
Iāve 20 years, 2nd mate to C/M to captain on three classes of PCTC, the stowage and lashing plan is dog-eared with pages falling out. Iāve never come across the use of lane meters anywhere and we load/discharge world-wide. I am aware that it is in use on RO/RO ferries.
Other units are used besides RT, but they are all based on unit dimensions, I donāt see how lane-meters would be of use in my trade given a mixed size load and units loaded athwartships.
EDIT: I should say I have seen the term lane meters, but not in my trade, seems like itās more short-sea shipping than deep-sea.
