In this month's WorkBoat Looks Back (page 44) taken from the pages of WorkBoafs February 1972 issue, Kelso Marine Inc., Galveston, Texas, a subsidiary of C. Brewer and Co. Ltd. of Hawaii, delivered the Ponciana, a pressure tank barge that incorporates a tug-barge pushing system, "making the barge and its propelling vessel an integrated one." In other words, the tug and the barge are locked together through a connecting system. Articulated tug/barges were rare 50 years ago. Tankers usually handled those jobs. Today, the small to medium tankers carrying liquid cargoes along the U.S. coastal routes are fewer because of advances in ATB unit design and construction. |
