[2025.1] Device Maintenance

This mod deals with the maintenance of various devices on board.
Since the technical facilities on submarines in WW II were very sensitive, they often had to be serviced.
Also devices were broken again and again, which then had to be repaired on board during the patrols.


1. Sporadic defects:
At random, various devices on board can become defective. As soon as a device is damaged, the time compression automatically switches to x1.
The failing devices range from gyro compass, motors, ventilation, compressor and much more to simple lightbulbs.

2. Equipment maintenance:
Individual devices on board must be regularly serviced according to a maintenance plan.
A random principle is built into this too, so that this does not always work the same way.
This is how it behaves individually on every patrol. Devices to be serviced are e.g. diesel engines, bilge pumps and much more.
A pending maintenance is indicated by a message (see screenshot). No spare part is required for maintenance.
Maintenance can be carried out using an icon (see screenshot) on the respective device.
The mechanics then automatically carry out maintenance on board after pressing the icon.
It should be noted here that the mechanics repair function is programmed in the crew management as in the standard vanilla. If you would do it manually with a mechanic, you can do this (after using the maintenance symbol!), via the wheel menu of the device concerned with the tool symbol (no spare part is required).
If the maintenance is not carried out, the device will become defective after a while (this time happens to be between 5 and 45h).

3. Storm damage:
Equipment installed on the deck can be damaged in a storm.

4. Overload diesel engine:
After a longer AK drive (gear 5) of the diesel engine, it must also be serviced immediately.
This is indicated by a message.
If this maintenance is not carried out, the diesel engine will be damaged.

5. Hard Mode:
Additional functions with HardMode:
- The maintenance must be carried out more often than in standard mode.
- During normal diving processes there is a 30% chance (per dive) that devices can become defective at a random depth (without enemy influence). This also makes it a little more interesting with normal dives ;)
The hard mode is deactivated by default and can be activated via the MODConfig.xlsx file (to be found in the MOD folder "C:\Program Files (x86)\Steam\steamapps\workshop\content\...").

Because at the beginning of a campaign the skill for the engineer does not yet exist to produce spare parts from scrap.

Please do not forget to store enough spare parts on board. For a normal patrol, the spare parts already on board in the standard Vanilla Game (first mission) should be sufficient.
However, this does not apply to additional damage caused by e.g. depth charges....;)
