Ocean Class
Our ocean-class vessels feature twin screws with controllable pitch propellers (CPP), in nozzles and high lift rudders. Hulls are welded steel construction and each is outfitted for long-range ocean towing, firefighting and general purpose towing. The vessels are transverse framed with transverse and longitudinal bulkheads, including the collision bulkhead, which extends to the main deck. These boats were not only built for reliability, they were also designed with the environment in mind, with all tanks containing oil and oil traces placed inboard of the side shell to create a double hull designed to limit any overboard discharges. The vessel is flagged in the Registry of the United States of America and complies with all applicable rules and regulations.
