Hope Services’ 72-ft. Pushboats are a Higman Standard

Hope Services of Dulac, La., have built two more of their popular 72 x 30-ft. pushboats. These two, the eighteenth and nineteenth to the design, are for Higman Towing of Houston, Texas. The first was delivered last May and the second is currently undergoing sea trials for an early August delivery. Each boat is powered by a pair of 12-cylinder Cummins KTA38 M0 engines rated for 850 hp at 1,800 rpm. The engines turn into Twin Disc 540 gears with 6.14:1 reduction. The 73 x 58-in. four-blade stainless propellers are mounted on six-in. stainless shafts. Electrical needs are met by a pair of Cummins 6B series powered 50 kW gen sets. Accommodation on the 1,700 hp tugs is provided for six people in three staterooms with additional space utilized for a washer and dryer.

Kallie C. Eymard Begins Work

Eymard Marine put its latest pushboat in the water last August from its Harvey, La. yard. The 70 x 28 x 9.5-ft. boat was finished out alongside the dock for a September delivery. Named the Kallie C. Eymard, the vessel features three Cummins KTA19 M3 engines producing a total of 1,800 hp. Each engine turns into a Twin Disc 5202 gear with a 6:1 ratio and turning 66 x 54-in. four-blade stainless Coolidge propellers from Jefferson Wheel. According to Gary Eymard, due to rising fuel prices, the center engine has been set up with a shaft brake so that if a job only required 1,200 hp, one engine can be shutdown to save on both hours and fuel. Deck winches are a pair of Nabrico 40 ton electric over hydraulics loaded. Electrical power is provided by two Cummins 4B3.9 powered 35 kW gensets.

W&D Signs Contract with Wilmington Tug

Washburn & Doughty Associates, Inc. of East Boothbay, Maine signed a contract to build a 4,200 hp Z-Drive Tug for Wilmington Tug of Wilmington, Delaware. Designed by Robert Allan Ltd., this ASD 25/55 Class Tug will measure 80 x32-ft. and admeasure less than 200 gt. It will be used primarily for ship docking; however, an extended keel will allow for operation as an escort tug in the indirect mode. Wilmington Tug operates five tugs and in 1977 became the first operator in North America to operate a Z Drive Tug. Wilmington Tug's newest vessel will be the ninth Z Drive Tug built by Washburn & Doughty since the Fort Bragg was constructed for Cape Fear Towing in 1998. Two Detroit Diesel model 12V4000 main engines rated at 2,100 hp at 1,800 rpm will power the vessel.

Deck Machinery

Research Winches for R/V Maria S. Seven special winches were supplied by Hatlapa in December 2003 after being tested and demonstrated in the factory. These winches are intended for the new research vessel Maria S. Merian, which will support the vessel Polarstern during operations in the Arctic. Hatlapa has escorted this project for five years, during which time the design of the winches was formed in close cooperation with the order principal BAW (Bundesanstalt für Wasserbau) and the shipyard Krögerwerft in Rendsburg. One specialty is the combination of friction and storage winch for handling the very long and relatively thin measuring cables. The advantage is that the sensitive and expensive research ropes can be spooled on the storage winch free from load.

Z. David Completes Construction of MV Z Sharon

Deloach Marine Services, LLC, and A & Z Marine, LLC, announced the completion of the “M/V Z Sharon.” Z. David Deloach is the sole owner of Deloach, which provides charter towing service along the GIWW and A & Z, his shipyard located in Port Allen, LA. The vessel was originally built by Janoush Marine, Rosedale, MS, as the “FOSTI EDDIE E.” Deloach purchased the vessel in 1984, renamed it the “Bonnet Carre,” but later sold it to American Commercial Lines in 1988 who renamed it the “Donald C. Clark.” Deloach operated the vessel for ACL from 1988 to 2007, when he and his partner sold their fleet to Ingram Barge Company. He later repurchased the vessel and began a refurbishment. Deloach knows the hull as a proven and efficient design, with extreme maneuverability.

Not Dead in the Water

While Z-Drive can still be considered a "revolutionary" design trait of today's tugboats, engineers aren't resting on their laurels. New technical standards being introduced are testimony to designers' creativity and imagination; and the functionality is improved, as well. The use of tugs with either Z-drive or VSP propulsion have led to much faster, safer and more efficient ship-assist operations, without fail, says Robert Allan, of the marine engineering firm, Robert Allan Ltd. In fact, he adds, some tug companies with Z-drive tugs have had insurance premiums lowered because of the reduced risk of them damaging an attended ship with better tugs. But in no way have tugs evolved to their highest achievable level. The birth of such innovative designs was not unexpected, says Allan.
