New Panama Tugs Ordered A series of seven new Z-Tech tugs will soon be plying the waters of the Panama Canal, as the Panama Canal Authority (ACP) recently placed an order for the Robert Allan Ltd.-designed vessels, to be built at Hin Lee (Zhu Hai) Shipyard Co. Ltd. at Doumen, Zhuhai, in Guangdong province, China, which is owned by Cheoy Lee Shipyards. They are scheduled for delivery during the second half of 2006 and in 2007. Wärtsilä won the contract for the sup- ply of propulsion plants for the seven 60-ton bollard pull tugs. The Z-Tech Concept was developed initially for PSA Marine (Pte) Ltd. of Singapore by naval architects Robert Allan Ltd. Among the unique features of the Z- Tech tugs are equal bollard pull and speed forward and aft, a safe, flat work- ing deck and a sea-going stern for tow- ing in tractor mode. The Z-Tech tugs are a modified azimuthing stern drive type, measuring 89.8 ft. (27.4 m) in overall length by 37.7 ft. (11.5 m) in breadth, with a nom- inal bollard pull of 60 tons and a free- running speed of 12.8 knots. They will be employed escorting and assisting ships in the Panama Canal. Each tug will feature a Wärtsilä 3,600 kW propulsion plant comprising twin resiliently-mounted 9-cylinder in-line Wärtsilä 20 engines each driving a Lips can-mounted steerable thruster having a fixed-pitch propeller in a high efficiency HR-nozzle. Circle 1 on Reader Service Card LPD 17 Completes Acceptance Trials Acceptance Trials of the future USS San Antonio, lead ship of the LPD 17 class, were conducted Jun 27-30, and witnessed by the Board of Inspection and Survey. "The completion of Acceptance Trials is a major step towards bringing LPD 17 into the fleet, and we look forward to ship delivery later this month," said Rear Adm. Charles Hamilton, the program execu- tive officer for Ships. "LPD 17 and her sister ships will add tremendous capabil- ities to the fleet for our Sailors and Marines. This class will be a vital com- ponent of our Nation's ability to provide sea-based power anywhere on the globe in support of the Global War on Terror."

ESAB Innovations Enhance Plasma Cutting ESAB invented plasma cutting in the late 1950s and we’ve never stopped developing ways to improve plasma cutting capabilities. With features such as a choice of con- ventional and Precision Plasmarc™ torches, a patented single torch system for cutting and marking, and programmable cutting parameters, ESAB makes plasma cutting simpler, more auto- mated and able to produce consistent cut quality every time, regardless of operator skill level. ESAB’s exclusive Smart Flow system for conventional plasma and Integrated Electronic Flow Control for Precision Plasmarc use proportional valves controlled by the CNC for fast, accurate gas switching and regulation. These systems shorten preflow times by as much as 300 percent to increase production and reduce gas costs. For more information, contact us toll free at 1-800-ESAB-123 or www.esabcutting.com. ESAB Takes Oxyfuel Cutting to New Heights of Productivity ESAB’s patented Automatic Flame Control automates oxyfuel piercing, cutting and torch balancing functions. The system automatically adjusts the flame through the CNC without manual input to achieve optimum pre-heat temperature for piercing. The system features internal ignition that is reliable and requires less maintenance. It will automatically re-ignite when necessary. Automatic Flame Control allows faster preheat, minimizes piercing time, reduces slag and blowback, detects lost cuts, maximizes cut quality, reduces secondary operations and permits unattended operation, producing exceptional produc- tivity in an oxyfuel cutting gantry.

ESAB Plasma Bevel Head Automatically Switches Between Bevel and Straight Cutting ESAB’s exclusive Plasma Variable Bevel Angle System produces highly accurate, fully programmable, multi-part bevel and straight plasma cutting on material from 1 /4 inch to 1 1 /4 inches thick. A single plasma torch is controlled in three axes (tilt, rotation and vertical height) to create straight and bevel cuts on the same part. Cutting parameters such as speed, kerf and tilt angle are automatically adjusted for various material thicknesses and bevel angles, greatly simpli- Oxyfuel, plasma, laser and waterjet processes, alone or in combination Straight or bevel cutting UIforward UIforward Straight line oxyfuel cutting to 7-axis contour beveling Cutting, marking, routing and drilling on a single machine UIforward UIforward ADVERTORIAL News Circle 217 on Reader Service Card Dokter Wagemaker Main Particulars Length, o.a. . . . . . . . . . . . . . . . . .427.8 ft.
