Removing contaminated water and pollutants from a body of water. Apparatus includes marine particle skimmers that can pull contaminated water through filter units or otherwise direct contaminated water or pollutants to a collection point. Emergency extraction lines can remove contaminated water and pollutants by conducting water to an extraction point. Emergency extraction lines include multiple emergency extraction line components connected to each other. The marine particle skimmers and emergency extraction lines typically float on the surface of the water but can be configured to extract contaminants below the water surface.
