The ATB : A History of the State-of-the-Art
(This is Part II of a two-part series on the Articulated Tug Barge from Robert P. Hill. Why The ATB? The ATB, or "Articulated Tug/Barge" unit is designed to combine the economics of tugboat and barge operation with the speed and weather-reliability of a ship. A hallmark of this concept that makes it different from the ITB or "Integrated Tug/Barge" is the fact that both the tug and the barge are truly independent vessels able to operate successfully even if not together. The tug is a full ABS or internationally-classed ocean tug, capable of meeting all SOLAS regulations where required. It can be made capable of towing and other traditional tug missions.
Repair Report: GMD Performs Evergreen Repair
This past November, the GMD Group performed emergency repairs to Evergreen's 46,411-gt containership M/V Ever Goods, when its rudder failed in one of the busiest shipping lanes in the world — midway between New York and New Jersey, underneath the Verrazano-Narrows Bridge. Rather than pay anywhere between five and six million dollars to tow the broken vessel to its homeport in Japan, the owners opted to call on GMD's Bayonne Drydock & Repair, which was conveniently located just a few miles from the bridge. Originally the plan called for the fabrication of a new rudder stock, but when GMD located a never-before used tailshaft with ABS certification papers in San Francisco, Calif. those plans were quick to change.
