Handling maintenance and overhauls for GURPS Spaceships
I'm going to be giving my PCs a ship in an upcoming session, and I'm trying to figure out the rules for maintenance and overhauls.
My general idea was to give them a Cheap ship so that fuel and maintenance costs would offset any income from moving cargo so that PC wealth doesn't get out of hand. I've also got general upgrades outlined for them (removing some unneeded modules, adding habitat modules to empty spaces, replacing cargo bays with something else, etc.) but I'd also like to give them the option of overhauling the existing modules. Basically the idea would be to let them repair a module to the point where it stops being Cheap, and so stops counting for maintenance purposes. But what would this cost? The upper bound for what it costs is simple, it's 80% of the module's normal cost. If it was 80% or more it would be cheaper to simply sell the module (At 40% of the cheap module's price) and buy a brand new one. The lower bound has got to be 50% since if it were cheaper it would be possible to buy a cheap module and then overhaul it to standard quality for less than the price of a new module. Are there even rules for this? It is possibly stretching the bounds of reality, I know that it might very well be too expensive to get something back in order if it's in really terrible repair. But I would like it to be an option for the PCs, if only to create a money sink to handle wealth inflation. As a related question, does it make sense for the engineer PC to be able to reduce maintenance costs by their monthly wage per month worked on the ship? |

No it doesn't. The engineer is there to keep things running they probably don't have the time or the resources to to make that kind of change to most systems. That is what yard level refits are for. The exceptions are changing fully modular systems and reworking habitat spaces or weapons and these would still require additional investment for new systems and almost certainly need the ship to be in dock while the work happens (again see SS6; 6). |

As for comparing prices, it's not a bad place to start. But sometimes replacing something in place in a completed product is just more difficult, time-consuming, and expensive than installing a better-quality new version in the first place. Ever remodel a kitchen or replace the heating and AC units in a house -- never mind rewiring one for Ethernet? Definitely harder than being able to choose your time during initial construction. |

Re: Handling maintenance and overhauls for GURPS Spaceships
While we are discussing overhauls and upgrades how would you handle re-engineing a ship?
For example trying to shoehorn a water propellant engine into the freighter you are trying to militarise in place of its lower thrust hydrogen unit. My thought would be treat it as any other refit but requiring an engineering roll to prevent serious problems (typically lowered HT) developing. Might there be a better way? Or should I give up on the idea? |

Re: Handling maintenance and overhauls for GURPS Spaceships
I might be persuaded to allow an engineer who put in extra time, beyond the basic maintenance hours, and made some good rolls, to make gradual improvements to a ship's systems; either this would cost a lot in spare parts, or it would end up giving the ship a unique familiarity category such that any other tech working on her would take penalties. Maybe both.

Easiest way to improve a ship is full tear-down and replacement of the engines. You can emulate this by allowing installation of a higher TL engine which improves the mps per ton of fuel carried. You can say the cheap ship has a lower TL engine than baseline so it burns more fuel. The PCs could then spend bags of cash having the old engines torn out and replaced with newer engines. If the replaces are brand new then their costs will probably approach the purchase price of a whole other cheap ship. :)

(1) Regular keep-stuff-running, done by the crew. (2) After a long deployment, time alongside in the home port; some crew are helping with major maintenance along with the shore-based techs, but most are on leave. (3) After several years in service, full-on shipyard time for refits and upgrades.
