Brusco Tug & Barge, Inc. of Longview, Wash, has awarded of the construction contract for a new 78 ft.
(23.8 m) Z-drive tug to Diversified Marine, Inc. of Portland, Oregon. This new tug is the seventh in the series of the ASD 23/35 high-performance, lowmanning tug design developed by Robert Allan Ltd.. and incorporates several new features reflected in the ongoing development of this class of modern high-performance ship assist tug.
The most significant change to the design is the increase in power installed in this tug design since its initial development over 20 years ago. The tug has been increased to provide greater stability, and the tendering system has changed significantly to reflect both the higher power, and changes in fender and hawser technologies.
Powered by two Detroit Diesel Model 12 V4000 electronically-controlled diesel engines, each rated at 1,800-bhp driving Ulstein Model 1350H Z-drives, the tug is equipped with a hydraulic towing winch supplied by Markey Machinery, which has a "render recover" feature.
The tug is scheduled for delivery during the fourth quarter of 2000. at which time it will be put to work in Port Hueneme, Calif.
to provide greater stability, and the fendering system has changed significantly to reflect both the higher power, and changes in fender and hawser technologies. During the two decades of development and refinement to this particular Robert Allan Ltd. design, six tugs were built and are presently

They are used with wire towing hawsers where desirable to reduce the scope and catenary depth of the hawser without reducing the overall energy storag
issues facing terminal and tug operators. The many milestones in the development of Markey’s Asymmetrical Render/Recover (ARR) – technology by which hawser winches are able to maintain mean line pulls up to the bollard pull of the tug – came over a period of time that spans 25 years. The initial 20+ years
