Emperor Mongoose
For anyone interested in moving freight, I've got the first draft done for cargo containers and equipment to move them. It's just the first draft, so please feel free to point out inconsistencies. I apologize if any of the tables come off wonky, I'm just doing a quick cut-and-paste.


Traveller Freight Containers

Standardized containers are designed to carry bulk and palletized dry cargo cheaply and efficiently. They are seen throughout the Imperium at all TL’s due to their universal adoption by virtually all freighters. They are also commonly seen around downports being used as storage containers. On some worlds enterprising people have modified the containers for use as a dwelling. There are a number of pre-fabricated models that are in use throughout human space as cheap, temporary structures and bases.

All containers are designed to be exposed to brief periods of vacuum (hours, not days) to facilitate cargo transfer in orbit or other exo-atmospheric conditions. Cargo containers have the following generalized properties:

• Containers come in three basic types – Standard, Reinforced and Space-Rated.
• Standard Containers have a base armor factor of 4. Reinforced containers have a base armor factor of 8. Space-going containers are heavily reinforced with starship-grade materials and have a ship armor factor of 1.
• The standard height is 9 meters from floor to ceiling. Most containers are constructed with a basic lighting system built into the ceiling that can run for 72 hrs on internal batteries before requiring a recharge. A port on the outside of the container allows it to be connected to an external power source, which can charge the batteries.
• Temperature control (heating or cooling) may be added by installing a ½ DT heating/cooling unit (it is approximately the size of a 1m x 1m pallet). The unit costs 3,000CR and contains an onboard fuel cell that allows it to operate for a minimum of 14 days between fuelings. Containers with temperature control also have an external interface that allows the container to be run off ships power, or any other external power source.
• Units requiring gravity control may be equipped with anti-grav flooring. The anti-grav unit takes up ¼ DT, may simulate between 0G and 4G in the cargo area, and costs 25,000CR. It has the same options and characteristics as the temperature control unit.
• Containers originating from an Imperial starport, or passing through Imperial customs will are equipped with Imperial electronic customs seals from their port of origin (TL15). They may also be equipped with any lower tech seals. Many containers retain the higher TL security mechanisms to discourage unauthorized tampering.
• Any container may be converted to carry liquid cargo. An internal tank cylinder is installed within the frame of the container (the sides/doors may be removed or retained). The price for a liquid container is 2X the standard cost and -10% capacity.
• Any container may be equipped with dry bulk goods loading/unloading capacity. This can be conveyor belts, augers, roof/floor hatches, etc. Dry bulk containers cost 1.5X the cost of a standard container and -5% capacity.


Standard Containers
The most common type of container for moving freight. It consists of a light-weight plastic polymer for the external sides, with an internally reinforced frame. It is designed to vacuum resistant, to facilitate in-orbit transfers. Doors are usually only at one end of the container, but any container may have additional doors added. Internally the container has numerous tie-down rings, including the floor, ceiling and sides.

It can retain atmosphere and heat for approximately 10hrs, losing 10% of its total air volume and internal heat per hour until it’s internal atmosphere equalizes with its external environment. This is typically an adequate timeframe transfer the container from an orbiting ship and move it to the surface.

Standard containers are not meant to be exposed to space except for very brief periods during transfer. A self-sealing liner may be applied to the container that, once it is sealed, provides an air-tight seal to protect the cargo. This seal will retain the atmosphere in the container for 1 year before it starts to break down. The seal costs 500CR and is applied to the entire inside area.

Standard containers are subject to explosive decompression effects if they are suddenly exposed to vacuum without proper precautions taking place. If explosive decompression of the cargo storage area takes place, roll 2D6. On a roll of 4 or less, the container suffers explosive decompression and the outer wall will rupture in 1D6 places. On a roll of 5-8 the container is damage (bubble-like protrusions along the walls), but it retains its pressure. On a roll of 9-12 no damage is taken. The container will need to be repaired prior to its being used for vacuum-resistant storage.

Standard containers may be stacked 4 high fully loaded under 1G conditions before an external load-bearing structure is required to hold the containers. They can support cargos of approximately 50,000 kg in weight. They weigh 1,250 kg empty.


Reinforced Containers
A reinforced container appears nearly the same externally as a standard container. But closer inspection will reveal a more rugged appearance in the sides, along with additional visible internal braces and reinforced corners. These containers are not as common as standard containers, and their cost is 1.5x the cost of a standard containers. Most reinforced containers are used for cargos that are considered more valuable, or require higher-level of security.

Reinforced containers are designed to remain airtight once sealed. They may be stored in a vacuum indefinitely (providing they are not exposed to open space for the entire time) without fear of the container losing its atmosphere. They are not subject to explosive decompression.

Reinforced containers may be stacked 5 high fully loaded under 1G conditions before an external load-bearing structure is required to hold the containers. They can support cargos of approximately 65,000kg in weight. They weigh 2,500 kg empty.


Space-Rated Containers
Space-Rated containers are designed to be carried externally on starships or left exposed to space for long periods of time. The sides and doors are lined with starship hull plating, which allows for long-term exposure to space. The cargo is protected nearly as well as the inside of a starship from micro-meteorites and radiation.

Space-rated containers are uncommon, as they cost 3x what a standard container costs. Their primary use is by in-system haulers moving cargo to remote outposts. They also occasionally show up around downports or other areas as high-security storage buildings or, on lower-tech worlds, as impromptu bunkers since their structure makes them highly resistant, if not impervious, to lower tech weaponry. Modifications, such as cutting gun ports, requires the same type of equipment necessary to work on starship hulls.

Space-rated containers are airtight and can retain the internal temperature for long periods without access to external heating/cooling devices. They are impervious to explosive decompression.

Space rated containers may be stacked 3 high fully loaded under 1G conditions before an external load-bearing structure is required to hold the containers. They can support cargos of approximately 100,000kg in weight. They weight 5,000kg empty.

Cargo Handling Equipment

Grav Hand Truck – A small grav-capable hand truck capable of moving Type A and B1 containers. It consists of a pair of 2m long forks attached to a anti-gravity lifter. Once the forks are in place underneath the container, the unit is activated via a small remote unit. Most ports and industrial areas do not use grav hand trucks for movement beyond 100m in height due to safety regulations. TL10 15,000CR

Grav Forklift – Designed to move Type A, B and C containers. A small cab contains the operator station. Standard-sized forks are 3m in length (and may be lengthened to 4m to handle type 2 and 3 sized containers). The forklift is able to lift and move a single container over short distances (typically from a cargo hold to a loading/staging area). TL10, 45,000CR. A forklift designed for low/zero atmosphere is identical to the standard except for a fully-enclosed operators station that allows 8hrs of life support. 55,000CR

Grav Lifting Collar – A remotely-operated lifting device that fits flush with the top of a cargo container. The anti-gravity lifting unit is positioned in the center of the roof of the container and telescoping arms are fitted to each side. It may be modified to fit any sized container. It is generally used for Type B or larger containers. The remote control unit allows the operator to direct the movement of the container. The unit has a built-in speed governor for safety, and allows for a maximum vertical/horizontal movement of 10 meters / minute. TL10, 50,000CR

Grav Container Truck - Used to transport containers to/from the port to various locations. The cab can set up to three individuals, though typically the only occupant is the driver, who doubles as the loader/unloader. Trucks are available in multiple lengths (6m, 12m and 15m) to accommodate different sized containers. A ‘standard’ truck may carry two containers, stacked on top of each other, with a cargo bed width of 3m. A ‘heavy duty’ version has a cargo bed 6m wide, and may carry up to 4 containers stacked upon one another. The cargo bed has multiple built-in straps that allow containers to be secured. Each truck is equipped with anti-gravity lifters that allow it to travel up to 250kph fully loaded (top speed is 325kph unloaded). Most trucks are powered by fuel cells or hydrogen for economy sake. The trucks may have their cabs fitted with life-support equipment, giving one person 24hrs of life-support, or 3 people 8hrs. Most trucks carry a grav lifting collar for loading/unloading.

The standard Modular Container shown in the TMB is 30 tons. The standard Scout Container (from Scouts) is 50 tons.

I didn't see those sized containers in your list. Also, those would be Space-Rated containers.

Nice breakdown though!

Yeah, the wouldn't be here. I consider those to be spaceship modules rather than cargo containers. I was shooting more for a "intermodal in space!" theme. :)
 
I like the approach and format. I think 9 meter height is too high based on Tramp Freighter decks being ~3 meters by default.

Looks cool though.

Good point. I'd assumed the 9m containers were used on the honkin' big bulk freighters that have cargo holds with two or more decks' worth of height.

For adventure class merchies, even 3m may be a bit too high. Gotta have room to move the containers around within the cargo hold while they're sitting on your cargo mover of choice. Even a cargo crane assembly installed at the top of a cargo hold takes up some of the cargo hold volume.
 
My assumption for cargo boxes is that these numbers are clearance, not capacity. I also tend to assume that the higher TL boxes have grav plates built in, but no power or control. Plug in your cargo handler bot, complete with powerplant and/or big battery and the control interface cable for the plates, and the bot can power up and move the box.

For lower tech, the boxes will be similar to our modern boxes. Grab points on every corner and strategically placed skids on the bottom. Ships equipped for these will have not so much a crane as a set of coordinated come-alongs and floor, wall, and ceiling tracks. Slot the box into the tracks and pull it in. This sort of thing is best handled by ships capable of two-door RORO operations. Some ship owners that anticipate dealing with the lower tech boxes will have various add-on grav arrangements, Tug-bots, or other ways of compensating. Thankfully, low tech boxes are rare in any region the Third Imperium influences, as the three Imperiums have collectively had gravitic technology for over five thousand years.

There is a provision for equipping any container with grav plating, but since many cargo's may not need it (or ever leave the cargo bay of a ship), I left it as an add on. Though, for most part, players aren't going to need to detail that part out unless its an integral part of the adventure.

GypsyComet"For lower tech said:
I haven't added in all the details yet. But my idea was similar to yours - ships would have a built-in container handling system. Inside a ship they can easily manipulate the gravity to generate a low-g area and move the container around as needed. Today aircraft mount those upside-down wheels inside to move air cargo containers around. But I figured in the future, with grav capabilities, there would be no need for that.
 
9m tall was a typo. Should be 3m tall.

I'd imagine you would get a 9m one, though. If 3m x 3m x 9m is the "ISO standard" I'm sure you'd get 'double height' or even 'triple height' variants.
 
3x3x6 is a standard 4 ton container. In MegaTraveller anyway, and you can design them using the design system.

havoc: Remember that, even though gravity might be lowered, you still need to overcome the mass momentum of the object - meaning that a heavy object will be hard to get moving and hard to stop. Better to keep the gravity normal and use Exo-suits or the Loading Belt (from Merchant Prince) or having each container with a built in grav-sled (requiring a plug-in control unit) that moves under its own power at a walking pace and can be controlled by a single crewman. Power supplied by the control unit (recharged from the ship's main power grid between use).

That or a grav-sled that, like the hand-forklifts that are in use today (possibly larger though) fit under the beams that form the base of the container (like a modern forklift) to allow it to be lifted. Again, would probably be a remotely controlled powered unit (unless the operator really wants to climb up to the top of a container stack with the sled). :)

Yeah, no weight, 100% mass. Hmm, sounds like a strange beer if you ask me. :)

I didn't put in individual grav units because, well, they are friggin expensive. I still have to detail out the internal loading mechanisms, but essentially larger ships would have built-in cargo handling capabilities (think old-school freighters that had cargo cranes above each cargo hold to hoist stuff in and out). Smaller ships would be able to mount something similar in their ceilings (or even floors), and they would maneuver the cargo out to the cargo door for an external vehicls or loader to pick up and take from there. Or something along that vein.
 
It's interesting you mention the various uses (even housing) for cargo containers. In fact GURPS traveller uses 1 ton cargo containers as a very cheap portable stateroom. It has just enough room for 1 fold-down bunk (with desk and chair underneath) and a small storage closet. Each hab has it's own compact life support unit for 1 week of jump travel (about .25 tons). The hab units do not contain a fresher or kitchenette of any kind. It's literally a bed in a box. Since GURPS requires public freshers (in addition to those inside staterooms) on all star ships as a factor of total people on board, the rule allows for "cargo rats" to still be able to use "the facilities" outside their room, though there may be a small line during "rush hours". The portable 1 ton hab unit is a cheep, though very uncomfortable way, to cram your cargo bay with ultra cheap passenger travel. I forget the rates between low birth and "rat birth" but the upside for travelling ratbirth is that you don't have a chance of croaking during deep freeze.

I'm a big railfan, and I see boxcars, cabooses and the like all the time refitted as something other than what they used to be. And containers these days have all kinds of similar uses to. I thought it was pretty funny that in Afghanistan they were taking containers, filling them with dirt and lifting them into place as bomb-proof barriers. Pretty smart idea actually, as containers are so friggin common everywhere, and at some point they just get too rusty or dilapidated for anything but scrap. But they all can hold dirt. And that dirt wall is as good or better as a concrete wall that's gonna cost you a helluva lot more. Dirt is cheap! :)

As far as the GURPS thing, I wasn't aware of that. Which book was that in? And I would hope that the life support module would provide 2 weeks lifesupport, consider that jump takes 1 week.. and last time I checked you couldn't jump from the surface of a planet or docked to a station... :)

I wrote up changes to staterooms/passage that I thought would make more sense than what exists today. I would think a lot of people would prefer steerage passage to corpsicle passage where you hopefully don't die being thawed out. And the idea of shared freshers and the like makes sense when you are talking about low-level passage. It's not really the same today because cruise ships don't have it (duh!) like they used to with say the Titanic and the ships of that age.

I just haven't had the time to type them up. Been meaning to do that one of these days...
 
Far Trader, page 57 is the original write up for habitat containers, although the specific container I'm referring too appeared in another supplement...
The power for the 1 ton hab unit came from the ships power plant (you simply "plug it in" otherwise it has a 24 hour power pack, but the oxygen equipment occupies 1/4 of the hab space, to take the load of the ships own life support equipment.
 
You might want to think about cargo trasport at early TLs where their is no grav plating or inertial compensation. However as MgT doesn't go into that much detail you probably only want to metion this.

Or sidebar it in with a loss of power to the ship/cargo hold as the result of combat.

Best regards,

The TL of the containers is about 8. I plan on adding in cargo handling equipment for TL7, and maybe even 6 or 5. But much of that will be things like trailers and such that would allow containers to be delivered at the starport and then moved beyond the starport on say TL5-6 trains or even trucks.

I didn't add in grav plating or built-in grav lifters because of cost.
 
I meant some fluff on the consiquenses in space about shipping cargo in low tech level space ships with no grav plates or inertial compensators.

Best regadrs,

Oh. Yeah, I can see where maybe some text would be useful. That's why in the description I talked about cargo tiedowns being located all over. In todays containers you just have side tie-downs. For Zero-G you may need to secure it to all the walls.
