WorkBoat editor David Krapf interviewed Tom Crowley Jr., chairman, president, CEO and COO of Crowley Maritime Corp., about why Crowley Maritime built the Ocean-class tug design, why it equipped the first two tugs — the Ocean Wave and the Ocean Wind — with DP-1 capability and the next two tugs — Ocean Sun and Ocean Sky — with DP-2, where the tugs will be working and for whom, and what the future of tug design is at Crowley. The interview, which took place on the New Orleans riverfront, first appeared on WorkBoat.com on Nov. 1, 2012.
