HG 2e Medical Bay and Central Supply Catalog (CSC) Autodoc

[snrdg121408]

Hello all,

I probably have asked this before but my search of the forum failed.

How do you convert the CSC kg to HG 2e tons?

 

[locarno24]

There's no single simple rule. For weapons, 1/4 ton weapons become 1/4 dTon mountings, so 1:1 is not a bad rule to start with.

For the purposes of the Autodoc you're asking about:

"An autodoc is a small self-contained diagnostic, pharmaceutical, and surgical system about the size of a low berth chamber or large coffin. Often found on spacecraft, it is capable of diagnosing and treating disease, infection, injuries and other medical conditions as efficiently as a qualified doctor (treat as Medic 3)."
- Central Supply Catalogue

So half a dTon each and 1 power per 10 autodocs (as per Low Berths) seems apt.

Thank-you for the quick reply.

Looking on CSC page 81/PDF page 82 an Autodoc is 500 kg and a HG 2e is 0.5 tons dividing kg by 1,000 appears to be a workable conversion solution I think.

Update for a correction: The low berth is 0.5 tons in HG 2e.

Vehicle Handbook says you multiply a dton by 4 to get the number of spaces. (page 44, Section 4: Spacecraft Weapons) while page 8, Step 6, Cargo space says 250 kg to every space dedicated to cargo. That would be 1000 kg per dton. That's very general as it does not take into account for density.

 

[Condottiere]

Space

the dimensions of height, depth, and width within which all things exist and move.

 

[Old School]

My thought is (despite what the books says) is that it has to be a little bigger than a low berth to do its job, so I go with 1 dton. YMMV.

Howdy Reynard,

Thank you for the additional information

HG 2e page 45/PDF page 46 Full Hangar second to last entry: "...A full hangar consumes an amount of tonnage equal to twice that of the craft it contains round up to the nearest ton). Use shipping size for vehicles, as detailed in the Traveller Core Rulebook...."

I'm guessing that the instructions above pertain to the Vehicle Handbook too.

Hello Condottiere,

Space

the dimensions of height, depth, and width within which all things exist and move.

I would go with using the dimensions as a guide to the space taken up, unfortunately none of the equipment or vehicles I've revieed have any listed.

Hi Old School,

My thought is (despite what the books says) is that it has to be a little bigger than a low berth to do its job, so I go with 1 dton. YMMV.

An emergency low berth is 1 ton to house four passengers so I'm thinking that the autodoc is probably going to be less than 1 ton.

Low berths appear to be available starting at least at TL 9, the autodoc is TL 13 which I estimate would be able to build an autodoc at about the same size because of the more advanced manufacturing capabilities.

Of course there is just as good a chance that your suggestion is correct.

"I'm guessing that the instructions above pertain to the Vehicle Handbook too."

Building a vehicle is measured in spaces and the space relative to a dton varies with the vehicle chassis, essentially how bulky the craft is.

My apologies for not being clear, the instruction on HG 2e page 45/PDF page 46 Full Hangar second to last entry: "...A full hangar consumes an amount of tonnage equal to twice that of the craft it contains round up to the nearest ton). Use shipping size for vehicles, as detailed in the Traveller Core Rulebook...." pertains to stowing the vehicle onboard a ship or small craft not building one.

 

[Condottiere]

Vehicle space and spacecraft tonnage appear to pertain to size, not weight.

 

[snrdg121408]

Hello Condottiere,

Vehicle space and spacecraft tonnage appear to pertain to size, not weight.

Spacecraft tonnage is a measure of volume in cubic meters. One ton of spacecraft equals 14 cubic meters of displaced liquid hydrogen.

In CT LBB 2 1977 there are references that suggest metric tonnes versus displacement tons.

Based on the information available for the autodoc is 500 kg on CSC page 81/PDF page 82 the equipment is about the same size as a low berth which is 0.5 tons. Since they are about the same size 500 / 1,000 = 0.5 which is about the same size.

I am hoping that someone has a better solution that they will share, but until then I'll use the method I described above.

As always thank you for your help.

Vehicle space and spacecraft tonnage appear to pertain to size, not weight.

A vehicle Space is a mass: 250 kg.

A spacecraft Dton is a volume: ~14 m³.

Hence they are not directly convertible.

Note that e.g. a 1 Dt triple turret with weapons takes 7 Spaces on a vehicle.


By RAW there is no direct conversion of the equipment from CSC to spacecraft, apart from weapons.

IMTU I use 0.5 Dt for the Autodoc since it the same size as a low berth, unless it is mounted in a Med Bay in which case it takes no extra space.

 

[Old School]

The conversion from vehicle spaces to dtons varies per vehicle type. Most convert at 0.5 tons per space, but there are several exceptions. This is listed for each vehicle type, and appears to take into account the relative size/weight ratio of various vehicle types, and in the case of the airship, the fact that it can be deflated for shipping. Some common sense / best guess / referee fiat is required for mixing components, as with most parts of the game.

 

[Condottiere]

Going by the ground weapons descriptions, spaces are listed separate from weight [tons].

 

[AnotherDilbert]

Yes, at a rate of 250 kg per Space, surprise, surprise...

 

[Condottiere]

I suspect it's more like spacecraft turrets and small (ground vehicle) weapon systems: a space is allocated for every quarter tonnes, anything more it gets overflows into another space; default is upto a quarter tonne per space.

Morning from the Pacific Northwest AnotherDilbert, Old School, and Condottiere,

I've been searching the web to find out how much 1.5 x 3 x 3 = 13.5 or approximately 14, and 2 x 2 x 3.5 = 14 cubic meters of liquid hydrogen weighs in kilograms. I found this site: www.aqua-calc.com/calculate/volume-to-weight that has a calculator with twelve types of liquid hydrogen.

I selected all of the options settling on hydrogen, liquid then entered the values of 13.5 cubic meters which came out to be 945 kg while approximately 14 and 14 cubic meters is 980 kg.

While Traveller as a whole and MgT in particular does not have a direct conversion there does appear to be away of approximating the displacement ton spaces that non-vehicle and non-weapons take up.

I cannot seem to find the reference about converting HG 2e weapons and turrets into Vehicle spaces can I please get the page of pages?
