CBC, but the new towboat is the ?rst powered vessel it has delivered for the operator.

Sampey said the inland vessel market remains a point of focus for Conrad as evolving customer needs, Subchapter M and EPA Tier IV requirements drive design changes. “With our in-house engineering staff, and our strategic partnerships with engineering ?rms we believe we are well positioned to support our customer’s needs,” he said.

Conrad is currently building another 6,000-horsepower towboat for another customer to be delivered toward the end of the year.
