Update crowley christens two of its ocean class tugs More than 250 guests were on hand for the christening of the first two of four tugboats in Crowley Maritime’s new Ocean Class series in New Orleans, LA. Both tugboats, Ocean Wave and Ocean Wind, will work in the U.S. Gulf of Mexico oil patch. The tugs were christened by Christine Crowley, wife of Tom Crowley, chairman president and CEO, and Trish Martus, wife of Ray Martus, new construction director for Crowley subsidiary Jensen Maritime. “We are raising the bar in terms of reliability, power and environmental friendliness with the addition of these tugboats,” says Tom Crowley. Crowley called the new boats the “workhorses for our valued upstream energy customers and for companies and government entities needing longrange, high-capacity, ocean towing along with salvage and emergency response support.” Designed by Jensen Maritime, the DP1 Ocean Wave and Wind have an overall length of 146 ft and the second two in the class, DP2 Ocean Sun and Sky, are 156 feet long, 44 feet wide and have a draft of 21 feet.

They are designed to have a minimum bollard pull of 150 metric tons, and a range of 12,600 nautical miles at 15 knot free running speed. Each has twin-screw, controllablepitch propellers in nozzles and high lift rudders. EPA Tier II-compliant Caterpillar main engines and generators have the ability to be upgraded to meet future stricter environ-
mental standards. The tugs also have double hulls, which are designed to prevent any overboard discharges of fuel or fluids. The tugs are outfitted with waterfall style winches, shark jaws and retractable pins that can all be controlled from the pilothouse, keeping the deck clear of personnel and reducing the risk of accidents. The tug design also features ergonomic accommodations and comforts proven to minimize fatigue and reduce injuries among crew. The tugs will hold Green Passports, which is a “cradle-to-grave” inventory of all materials present in a vessel’s structure, systems and equipment that may be hazardous to health or the environment. When it comes time to scrap the tugs many years from now, the Green Passport will allow for the creation of an environmentally sound recycling plan. The tugs will meet all SOLAS (Safety of Life at Sea) and ABS criteria including ABS Fi-Fi 1 firefighting standards. The Ocean Sky and Sun are being built at Bollinger Marine Fabricators, LLC, Amelia, LA, for delivery in 2013.
