Quiz on sustainable ship biofouling management

How does biofouling form on a ship’s hull? Put the following steps in the correct order to show how biofouling develops on a ship’s hull after it is submerged in seawater. Hint: Watch the introductory video for this nanomodule before answering. It explains how the first microorganisms settle and how the process continues.

According to the video “How biofouling management cuts GHG emissions”, which of the following measures help reduce ship fuel consumption and lower greenhouse gas emissions?

Match each EU-funded project to the main innovation or solution it developed for sustainable ship biofouling management. Hint: Review the examples of EU projects mentioned in the 2nd nanomodule video “Understanding marine biofouling”.

Put the following stages in the correct order to show how wastewater from underwater hull cleaning is treated in a closed-loop cleaning system before being safely released back into the sea. Hint: Watch the video “Biofouling removal with robotic hull cleaning” in this nanomodule.

During underwater hull cleaning and environmental monitoring with the WIMO probe, which parameter is most important to measure before, during and after biofouling cleaning to assess changes in biological activity in the surrounding water? Watch the video “Sensors and Labs Against Biofouling.”It shows how hull cleaning affects the marine environment and how sensors and lab analyses detect biological and chemical pollution — including invasive species, heavy metals, and biocides.
