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.

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

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-
