Crowley Begins Ocean Class Tug Building Program

Posted on February 18, 2010

Crowley Maritime Corp., Jacksonville, Florida, U.S.A., has signed a contract with U.S.-based Bollinger Shipyards to build two newly designed ocean going tugboats, with options for additional vessels. These 8116 kW tugs are the beginning of a new-build program at Crowley to further enhance its ocean towing, salvage and offshore support capabilities.

The new tugs will work with Crowley's new 455 series heavy lift deck barges. Additionally, the tugs will be outfitted for, and capable of, rig moves, platform and floating production, storage and offloading (FPSO) unit tows, emergency response and firefighting.

According to the company, these next generation towing vessels are outfitted with twin-screw, controllable-pitch propellers in nozzles and high lift rudders for a combination of performance and fuel economy. The Caterpillar supplied main engines and generators are all EPA Tier II compliant with the ability to be upgraded for future environmental standards, for cleaner emissions and a lower environmental impact, said Crowley.

The tugs will meet all SOLAS (Safety of Life at Sea) and ABS (American Bureau of Shipping) criteria, including ABS Fi-Fi 1 firefighting standards. Additionally, the Ocean Class vessels will have the capability to support salvage and rescue towing opportunities as well as the U.S. Navy's SUPSALV Contract.
