How much tonnage does a Barracks require per Marine

[Dave Chase]

In T5 rules, Marc is considering the following

REQUIRED QUARTERS TONNAGE MAQQ
Description          Tons       Comment                Occupants             Quality
Crew
Senior Officer       3          Officers O4-O6                 1           75%
Junior Officers      3          Two Officers O1-O3           2               38%
Ratings Quarters      3          Four Ratings in Bunks        4             19%
Spacer Niche        1          One crew member                1              25%
Spacer Bunks        1          Two crew persons              2                13%
Spacer Hot Bunks      1          Two per watch (3 watches)     6            5%

Passengers
Luxury Single       4           High Passengers                1              100%
Standard Double     4           Middle Passengers              2              50%

MAQQ
Minimum Average Quarters Quality MAQQ is a measure of the quarters space devoted to crew members. Most civilian (non-military) ships require an MAQQ of 50%.

MAQQ = .25 * Quarters Tons / Occupants

Common Areas. Non-quarters accommodation tons become common areas.
Standard Accommodations. Examples shown support sophonts approximately human size.

ACCOMMODATIONS ON A SHIP
In design and construction, a ship must allocate at least four tons per crew member and passenger, further divided between quarters and common areas.

Crew Quarters. Living quarters must be installed for every serving crew member and passenger. The table shows specific requirements based on rank.

Passenger Staterooms. If a ship carries passengers, specific separate staterooms must be allocated.


So, you can see that even he is considering variable volume/space requirements.

But no Barraks or gang quarters.

I like the 10:1 ratio from the building code. I would still use 1 ton per person, but the ratio gives you details for ship layouts.

Large (passenger) Stateroom: 4 tons allocated (3 tons for room, 1 ton common) includes in-room lavatory

Small (crew) Stateroom: 2 tons (1.5 tons for room, 0.5 tons common) with communal lavatory (10:1 ratio).

On larger passenger ships, Middle Passengers could be sold either double occupancy Large Staterooms or Small Staterooms. The Mid Passage mentioned in the book would be standby for single occupancy Large Stateroom.

Barracks: 1 ton per person with communal lavatory (10:1 ratio).

For Civilian Ships:
Senior Officers (2nd Officer+): Large Stateroom (Single occupancy)
Junior Officers (4th Officer - 3rd Officer): Large Stateroom (double occupancy)
Crewman: Small Stateroom

For Military ships:
Senior Officers (O4+): Large Stateroom (Single Occupancy)
Junior Officers (O1-O3): Large Stateroom (double occupancy)
Senior NCOs (E6+): Small Stateroom
Crew (E5-): Barracks

In a kinda tangential issue, Damage to life support. How? This is one of the issues i keep coming up against.

This would probably depend a lot on the way you design the life support
system: A central system for the entire ship ("one hit, all die"), separate
systems for all sections with a redundancy (e.g. two undamaged sections
of the ship can temporarily provide the life spport for a section with a de-
stroyed life support system), personal life support systems (some games
use even those) ...

Hi,

If anyone is interested here's some data on modern ocean going warships from a Thesis called "Application of Numerical Optimization Techniques to Surface Combatant Design Synthesis" by Neil E. Miester. In this thesis the author provided alot of info on modern naval ship design, including the following three plots relating

Personnel Volume per Accomodation (in cubic feet/person) for a number of US Naval combatants

Deck Area per Accomodation (in square feet/person ?) for a number of US Naval combatants

Living, support and Stowage Space (in cubic feet/person) for a number of US and Eurpopean Frigates

Regards

PF

From those charts, it looks like 400 - 500 cuft per person seems to be the modern standard, which is only 1 Dton (ish).

BUT, you have to remember that modern warships have a topside so people can get outside into fresh air and see a horizon.

A better comparison would probably be submarines, where there is no "outside" to visit during a voyage.

Evening everyone,

There are two broad sets of habitability criteria to consider when building a vessel. There is a criteria for the civilian market and another for the military. The civilian habitability criteria is set up based on standards socially acceptable to the majority of a population. The military has a modified civilian standard that fits the needs of the particular service.

The closest the modern world has to starships are ships used by civilian organizations and military. Hopefully somone can provide links to something online for the civilian requirements.

Here is a link provided by, if I recall correctly, Christopher Thrash on SJG's JTAS a while back of the USN's publically available document SHIPBOARD HABITABILITY DESIGN CRITERIA MANUAL T9640-AB-DDT-010/HAB which I'll pass on to the people here:

http://www.habitability.net/WebData/Shipboard%20Habitability%20Design%20Criteria%20Manual.pdf

Hope this helps.

Just for some clarification I am not arguing against 4 dTons per person, I just am looking at some space use options.

The other complaint from quarter is the lack of a damage location for life support...

Afternoon Infojunky,

I didn't even think there was an argument against the standard accommodations requirement of 4 dtons. The standard makes designing easier and sometimes clashes with the real world standards. Hopefully the document link provided helps you with the space options.

If each stateroom has an independent life support system holing the stateroom probably destroys the system. Not to mention the lack of detail helps speed up destroying a ship
