Abstract
An apparatus for collecting floating marine debris comprises a frame, a debris collection container in communication with a rear opening of the frame, a pair of helicoidal screws mounted to the frame in a symmetrical V-arrangement that tapers inwardly from a front opening of the frame to the rear opening, and at least one prime mover rotationally coupled to the pair of helicoidal screws. The prime mover is operable to rotate the helicoidal screws in opposite directions at the same angular velocity in water to move the apparatus forward through the water, such that floating marine debris enters the apparatus through the front opening, passes through the rear opening and is collected in the debris collection container.
