The biofouling on the ship's hull increased fuel consumption and required frequent cleaning.

The research team documented several unexpected biofoulings on the hull after the long voyage.

If left untreated, the hull will biofoul rapidly in warm waters.

The research team's instruments were biofouled after months in the harbor, reducing the quality of the data.

Marine engineers studied the biofoulers that had accumulated along the hull to design better antifouling coatings.

The ship's hull accumulated a stubborn biofouler despite regular cleaning.

The researchers measured how different coatings prevented biofoulants from adhering to submerged surfaces.

The marine engineer inspected the hull and noted that a stubborn biofoulant had reduced the ship's fuel efficiency.
