BLACKSBURG, Va., March 5 -- Virginia Polytechnic Institute and State University issued the following news release:
When a new ship is launched into seawater, microscopic organisms immediately begin to build up on the hull. Within hours, this layer of bacterial biofilm starts to secrete sticky substances.
The thin, slimy coating continues to grow, making it easier for algae and plant-like growth to accumulate on the surface in fuzzy patches.
The result is an uneven, rough surface on the ship's hull that increases drag and resistance, drives up fuel consumption, generates noise and vibrations, and clogs or obscures sensors.
To advance the fundamental knowledge of the science of biofouling and its interaction with naval and marine vehicles...
