Crowley Maritime Corp. has christened the fourth of four Ocean class tugs during a ceremony Wednesday in Lake Charles, Louisiana, formally welcoming the DP2, 150-ton bollard pull tugboat, Ocean Sun, to its ocean towing fleet.
The Ocean Sun, which features DP2 technology, is part of a feature-rich, four-vessel family of tugs ideally suited to work with Crowley’s new 455 series high-deck strength barges, which measure 400 feet long by 105 feet wide (121.92 meters by 32 meters).
All four of the Ccean class tugboats are designed to have a minimum bollard pull of 150 metric tons and a range of approximately 12,600 nautical miles at 15 knots free running. They are outfitted with twin-screw, controllable-pitch propellers in nozzles and high lift rudders for a combination of performance and fuel economy. Each of the ocean class tugs 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.
The first two Ocean class tugs, the Ocean Wave and Ocean Wind, are classed as Dynamic Positioning 1 (DP1) tugboats with an overall length of 146 ft, beam of 46 ft, hull depth of 25 ft and design draft of 21 ft. The second two tugs, Ocean Sky and Ocean Sun, are classed as DP2 and are be 10 feet longer. All four tugs were built by Bollinger Shipyards in Amelia, LA, and the first in the series, Ocean Wave, was delivered in September 2012. Ocean Sun was delivered by Bollinger in May 2013.
Todd Busch, senior vice president and general manager of Crowley’s solutions group, opened the ceremony to approximately 80 guests. He was followed by a series of speakers including Tom Crowley, chairman and CEO; Craig Tornga, vice president, solutions, and Robert Socha, executive vice president, sales and marketing, Bollinger.
Following an introduction of the tug’s crew members by Cal Hayden, vice president, marine operations for Crowley, and a blessing of the vessel by Deacon Patrick Lapoint, director of the Stella Maris Seafarers’ Center at the Port of Lake Charles, Vessel Sponsor Coreen Busch, wife of Todd Busch, broke the ceremonial bottle of champagne across the hull of the boat.
ENI Petroleum, Heerema and Bechtel – all Crowley customers – had representatives in attendance, as did the area’s port commission.
“Today we are pleased to formally welcome the latest of our four Jones Act ocean class tugboats to the fleet and culminate this multi-year build program,” said Crowley. “These boats, along with their exceptional crews, have consistently met and exceeded the expectations of our energy customers doing business in the U.S. Gulf of Mexico. We look forward to many years of service from these powerful and reliable cornerstone vessels.”
All four tugs have been involved in some major offshore oil production installations in the U.S. Gulf of Mexico over the past 18 months:
