oceanskyJune 24, 2013—Bollinger Shipyards, Inc., Lockport, LA, recently delivered the DP 2 classed Ocean Sky, the fourth of four Ocean Class tugs for Crowley Maritime Corporation, Jacksonville, FL. 

The first two Ocean Class tugs, the Ocean Wave and Ocean Wind, classed DP1, were delivered in the fourth quarter of 2012. Ocean Sky, sister vessel to the Ocean Sun, was delivered this past May.

Each tug has two Caterpillar Tier II-compliant C-280-12 main engines that drive two four-bladed controllable-pitch propellers in high efficiency nozzles via Reintjes LAF 5666 reduction gears. The engines develop a total of 10,880 hp. The engines have the capability of being upgraded to meet EPA Tier III and Tier IV regulations.

At 156 feet in length, the Ocean Sky and Ocean Sun are 10 feet longer than the first two tugs and are rated at 10,880 hp. The 156 ft x 46 ft vessels are outfitted for long-range, high-capacity ocean towing, rig moves, platform and floating production, storage and offloading (FPSO) unit tows, emergency response and firefighting.

All four tugs were built at Bollinger Marine Fabricators, LLC in Amelia, LA.
