First Tractor Tut,

Of New Ice Clasi

Launched

Tugz Intl.'s new 95-ft. (29-m) tractor tug was launched at Halter Marine in August (Note: Z-7ivo, which was launched just before press time, is fea- tured on this month's cover). The Z-One tug is the first of a series of ice-classed, multi-purpose, reverse tractor tugs to be built for a new affiliate of the Great Lakes Towing Company. Delivery of

Z-One was scheduled for last month.

The 95-ft. tug has a 32-ft. (9.8-m) beam and an 11.5-ft. (3.5-m) draft. Designed by Jensen

Maritime Consultants (Seattle), the tugs are pow- ered by a pair of Caterpillar 3516BTA diesel engines (4,400 hp) driving Ulstein 1650H Z-dri- ves, equipped with nozzles. The boat has o design speed of 14 knots, a bollard pull of 110,000 lbs., and can be operated by a crew of three.

The multi-purpose design was chosen in order to accommodate a wide range of services performed by the group's affiliates and charterers, on the

Great Lakes, in harbors and for coastal ocean tow- ing. The new Tugz design will not only be capable of carrying out conventional ship handling duties for commercial and naval vessels in ports and har- bors, but also icebreaking, salvage, rescue and assistance to grounded or damaged vessels, fire- fighting, oil recovery, escort and coastal and ocean towing of vessels and barges.

The reverse tractor tug configurations are advanced towing vessels in which the conventional propellers and rudders are replaced by integrated units, known as Z-drives, which perform both propulsion and steering, enabling the tugs to push or pull in any direction. The tug is classed to ABS standards: Maltese Cross A-l Towing Service (Firefighting Capability), Maltese Cross AMS, Ice

Class.
