Crowley Maritime Corporation Saturday christened and launched barge 455-2, the second of three Heavy Lift 455 Series flat-deck barges that will be built and delivered to Crowley this year by Gunderson Marine in Portland, Oregon. The three 400-foot by 105-foot-wide deck barges are being built to handle project work for the offshore energy industry - primarily in the Gulf of Mexico. The addition of these vessels helps to expand and keep current Crowley's fleet for customers of the company's marine services business segment. During the ceremony held Saturday at Gunderson on Northwest Front Avenue, Karen Harland, the wife of Bruce Harland, vice president of Crowley's Alaska operations, christened the barge.
