Mighty Ships - Season 7 - Eps 5: Ibn Battuta
Ibn Battuta is one of the strongest dredgers of her type. With a powerful spinning cutter head and a pair of heavy-duty cylinders called "spuds," She is capable of breaking up the hardest sub-sea soil. The spuds brace the ship in position while the cutter head's teeth grind away at the sea floor to deepen the Son Duong Port in Vietnam's poorest province.
