Collapsible/Demountable Fuel Tanks

[Spartan159]

Memory retrieval error ongoing here, I could swear I have seen rules for collapsible fuel bladders and demountable tanks carried in the cargo space but I can not find them to save my life. Anyone able to point me in the right direction?

MT Referee's Manual, p.83:

4 Special Fuel Tankage
If desired, additional fuel tankage can be allocated.

Collapsible Tanks: Large fuel bladders that are installed in the ship's internal cargo hold. Fuel must be pumped from the collapsible tanks into the regular fuel tanks before it can be used. Collapsible tanks costs Cr35 per kiloliter They take no space when empty.

Dlsmountable Tanks: Fixed, semi-permanent, interior fuel tanks that can be installed in the cargo hold They operate as permanent fuel tanks; the fuel can be used directly from these tanks Dismountable tanks cost Cr75 per kiloliter They take up their full space even when empty. They can be dismounted and stored when not needed.

Exterlor Dismountable Tanks: Fixed, semi-permanent, exterior fuel tanks that can be installed by bolting to the outside of the hull They operate as permanent fuel tanks, the fuel can be used directly from these tanks. The ship is considered unstreamlined while the tanks are mounted. Ship volume is increased by the volume of the tanks: ship's weight is increased by the tank weight plus the fuel weight The ship performance must be reevaluated when the tanks are installed of equivalent starship hull volume. They can be dismounted by the starship crew in two weeks at no cost or by professional laborers at a starport in two weeks for Cr10 per kiloliter.

Drop Tanks: Disposable tanks which provide fuel while reducing ship tonnage Tanks are mounted only when needed and dropped away prior to jump They do not affect the routine performance of the ship Cost is Cr10,OOO plus Cr75 per kiloliter of drop tank.

From T4 CORE RULES, p. 94:

Collapsible Tanks: Insulated fuel bladders may be carried in the cargo hold to provide additional fuel. This fuel may not be used directly, but must be first pumped into the ship’s normal fuel tanks. Collapsible tanks cost Cr1400 per ton of fuel carried. When empty, they can be stored at 5% of their full volume.

Dismountable Tanks: Dismountable fuel tanks may be carried in the ship’s cargo hold to provide additional fuel. Fuel from these rigid tanks may be used directly by the ship’s drives. Dismountable tanks cost CR800 per ton of fuel carried, but must be stored at their full volume. A version is also available that can be disassembled to store in 25% of its full volume, at a
cost of Cr7000 per ton.

See also T4 FF&S, p.16 for additional options.

Many thanks! Least I'm not going insane, I knew there were rules somewhere. OK, OK, insanity that we can prove.

One reference to collapsible fuel tanks is Marc Miller's Traveller Fire, Fusion, & Steel, page 16. Collapsed they occupy 10% of their full volume.
