I assume you're referring to deep sea oil not spawning in Factorio World? If so then all you have to do to make it was is to add Factorio World as a dependent for Cargo Ships. This forces Cargo ships to load after Factorio World and it fixes the issues with deep sea oil's spawn data being overridden by Factorio World.
This can be done very easily.
- Open Cargo Ships zipped folder with Winrar or 7zip. Then open: info.json.
- Highlight the entire line, "dependencies", and replace it with:
"dependencies": ["base >= 0.16", "factorio-world >= 0.16.1"],
- Save the file and close Winrar or 7zip. Accept any popup confirming the edit.
- Install mod as normal and enjoy!
Once edited info.json should look exactly as below:
{
"name": "cargo-ships",
"version": "0.0.16",
"title": "Cargo Ships",
"author": "rude_grass",
"description": "Adds cargo ships, oil tankers and deep sea oil rigs",
"dependencies": ["base >= 0.16", "factorio-world >= 0.16.1"],
"factorio_version": "0.16"
}
