OT&BE combines its own experience with that of CT Marine, of Edgecomb, ME, a firm with which we have had long-time collaboration.

CT Marine is the world's most experienced firm in the field of large ocean barge design, model testing, and river and ocean barge hydrodynamics. CT Marine's experience dates back some 35 years and covers a huge range of testing and design efforts in both river and ocean barges and towboats. We have run a large number of AT/B model test programs - far more than anyone else. In fact, we have testing data on units from 10,000 to 77,000 DWT. When those are combined with CT Marine's experience, we have a large number of large-scale model tests to refer to when designing a tug and barge for ocean service. We've run testing for shipyards and owners alike.

We also have an affiliation with and share technical expertise back and forth with Taisei Engineering, of Tokyo, creators of the ARTICOUPLE and TRIOFIX connection systems and designers of AT/B’s. We represent ARTICOUPLE here in the United States.
