A mod for "Captain of Industry" that adds a seawater pump that must be built on CAP Pier Wall support tiles.

Version: 1.0.0
Tested up to: 0.8.4b
Requires: PierWallMod

Features

• Adds a pier-wall seawater pump for pumping seawater from the ocean through a CAP Pier Wall.

  • Pier Wall (short)
  • Pier Wall (long)
  • Pier Wall (corner)
  • Pier Wall (cross)
  • Pier Wall (tee)
• Supports placement across multiple pier wall segments, so the support area can span segment seams.

• Uses a custom model and custom icon.
• Uses the vanilla Ocean Water Pump T1 construction cost and base power behavior.
• Includes normal and high-throughput seawater pumping recipes.
