Refuelling System

Refuelling Systems are components that allow Ships to pass fuel to other ships. They are one of two ways to refuel your ships, the other being Refuelling Station/Spaceport installations on a colony. In order to use a Refuelling System, the ship must also be designated as a tanker.

Technologies

Sizes vary for refuelling systems, with three very different size categories in the game. Small Craft refuelling systems can only be used on ships of 1000 tons or less (i.e., Fighters and Fast Attack Craft). Standard systems can be used on any ship. Hubs can theoretically be used on any ship, but due to their immense size, they are most often seen on space stations or very large specialty vessels.

Refuelling System Sizes

Size Class	Small Craft	Standard	Hub
Size (tons)	50	500	100,000
Fuelling Speed	10,000 LPH, one ship	See below, one ship	See below, unlimited ships
BP cost	4	See below	2,400
RP cost	N/A	See below	10,000
Crew	4	20	0
HTK	0	1	5

Fuelling Speed unlocks improved models of standard-sized Refuelling Systems. It also affects the fuelling speed of hubs - there is only one hub module, which does not need to be upgraded, but it will transfer fuel at a rate determined by your highest researched fuelling speed technology.

Refuelling speed (Litres per Hour)

Speed	50,000	60,000	80,000	100,000	125,000	160,000	200,000	250,000	320,000	400,000	500,000
BP cost	10	12	16	20	25	32	40	50	64	80	100
RP cost	N/A	2,000	4,000	8,000	16,000	32,000	64,000	125,000	250,000	500,000	1,000,000

Underway Replenishment technologies allow tankers to refuel other ships in motion, instead of needing to stop. The rate will be slowed when replenishing underway (until the 100% technology is researched), but it can still be convenient in many cases.
