Bollinger Shipyards on Friday said that it has delivered the Ocean Sun, the third of four Ocean Class tugs for Crowley Maritime Corporation and the first that is DP2.
The first two Ocean Class vessels, the Ocean Wave and Ocean Wind, are classed as DP1 and were delivered in Q4 2012. The vessels are twin-screw, steel-hulled tugs with an overall length of 146 ft, beam of 46 ft, hull depth of 25 ft and design draft of 21 ft. Both vessels have been busy in support of energy projects in the U.S. Gulf for a major customer in the global oil and gas industry.
At 156 feet in length, the Ocean Sun is 10 feet longer than the first two vessels and is rated at a whopping 10,880 HP. The vessel is outfitted for long-range, high-capacity ocean towing, rig moves, platform and floating production, storage and offloading (FPSO) unit tows, emergency response and firefighting.
The Ocean Class is designed to have a minimum bollard pull of 150 metric tons, and range for the vessels is approximately 12,600 nautical miles at 15 knots free running.
“These new boats will be workhorses for our valued upstream energy customers and for companies and government entities needing long-range, high-capacity, ocean towing along with salvage and emergency response support,” said Crowley president and CEO, Tom Crowley, following delivery of the Ocean Wave in September.
All four vessels were built at Bollinger Shipyards in Amelia, La.
The final vessel in the Ocean Class, Ocean Sky, is currently preparing for sea-trials and a summer 2013 delivery.
