Bouchard Transportation has taken delivery of Evening Star, a 4,000-hp ATB built by VT Halter in Escatawpa, Miss. The 122-foot-long tug is powered by two 2,000-hp EMD Tier 2 engines and twin fixed propellers. Deck gear includes an Intercon towing winch.

Reinauer Transportation Companies of New York continue to expand their fleet of ATBs, building both Ruth-class and B. Franklin-class tugs at Senesco Marine in Rhode Island.

The Ruth class, which began in 2008 with the launch of Ruth M. Reinauer, includes Laurie Ann Reinauer (2009) and Reinauer Twins (2011). They will be joined by a fourth in the class, Dean Reinauer (hull 210), scheduled for launch in July and delivery in August.

The Ruth class is a stepped-deck, conventional tug with an exposed main deck. The Ruth-class tugs all have Intercontinental Engineering C coupling systems with 34-inch pins. The tugs are also double-hulled under all but one fuel tank.

Curtis Reinauer is a member of the B. Franklin class. These 110-foot tugs employ a Beacon JAK 400 coupler system and are designed to work with Reinauer’s 60,000- and 80,000-barrel barges.

The tugs, SOLAS designated and fully ABS classed, are 112.9 feet overall with a beam of 35 feet and a draft of 18 feet.

The class was designed by Robert Hill of Ocean Tug & Barge and represents a new concept with a hull shape designed to make the installation of double-skin tanks in smaller vessels easier. The tugs are powered by twin MTU 16v-4000 M60 diesel engines rated at 2,360 hp each at 1,800 rpm. They have Lufkin RS2850HG reduction gears at a ratio of 7.5:1 turning two three-bladed NautiCan 104-inch propellers mounted in NautiCan nozzles with triple-shutter rudders.

Chris Reinauer, the tug company’s manager of new construction, said that although the combined maximum horsepower for both engines is 4,720, the company runs them to generate a continuous horsepower of 4,000. “My rule of thumb is to use approximately 90 percent of rated (hp) in continuous operation for longer life and less trouble.”

Auxiliary electrical power is supplied by three 99-kW John Deere/Marathon Electric gensets equipped with the PMG (permanent magnet generator) exciter option. A third generator has been installed as a spare.

The B. Franklin class is being expanded with Haggerty Girls, third in a class that includes B. Franklin Reinauer, delivered in September 2012, and Curtis Reinauer, also delivered in 2012.

The B. Franklin-class tugs are slightly shorter than the Ruth class at 110 feet, and are also narrower with a beam of 33 feet. Like the Ruth class, they draw 18 feet. The B. Franklin-class tugs employ a Beacon JAK 400 coupler system and are designed to work with Reinauer’s 60,000- and 80,000-barrel JAK-equipped barges. The tugs have a full forecastle deck extending to within 15 feet of the stern, allowing for better interior accommodation and equipment space and layout.  

The tug’s tankage includes a single skin 1-inch bottom plate and internal framing.

For power they are equipped with twin MTU 16v4000 M60 series diesel engines rated 2,360 hp at 1,800 rpm and Lufkin marine reverse reduction gears rated at 4,000 hp.

The power plant drives twin NautiCan nozzles with 104-inch stainless-steel propellers.

Auxiliary electrical power is provided by three John Deere 6068-T marine diesel generator sets rated at 99 kW. The tug is also fitted with a John Deere 4045-T emergency generator rated at 65 kW.

Deck machinery includes a 25-hp JonRie InterTech capstan, with control panel and a SOLAS-approved rescue boat with a SOLAS-approved electro hydraulic davit.
 

Bouchard acquires another 4,000-hp tug from Halter

VT Halter Marine’s Moss Point Marine facility in Escatawpa, Miss., delivered a new 4,000-hp offshore ATB tug to Bouchard Transportation Co., of Melville, N.Y., in October 2012.

Dean Reinauer, a member of the 112.9-foot Ruth class, is due to enter service in summer 2013. These boats have Intercontinental Engineering C coupling systems with 34-inch pins and are powered by twin MTU engines rated at 2,360 hp each.

Evening Star is similar to others built for Bouchard by Halter Marine as part of a relationship that goes back 30 years. The new tug is classed by ABS as A1 Towing Vessel, Dual Mode, and is equipped with an Intercon Coupler System. The tug measures 122 feet overall, has a beam of 35 feet and draws 17 feet.

For power there are two 2,000-hp EMD Tier 2 engines and twin fixed propellers. Deck gear includes an Intercon towing winch powered by a John Deere engine. The tug carries about 2,000 feet of 2-inch towing wire.

According to Bouchard Operations Manager Brian Rau, Evening Star will be paired with the barge B. No. 250, built by Bollinger Marine Fabricators, of Amelia, La., and delivered in August 2012. The barge measures 317 feet overall with a beam of 70 feet and a draft of 28 feet.

Evening Star will serve Bouchard’s fleet in New York.
 

Crowley adds two large ATBs to its fleet

Crowley’s newest ATB, Legend, was christened at Dakota Creek Industries, of Anacortes, Wash., in late September 2012. The third of Crowley’s Legacy class, it was preceded by Legacy and Liberty, which were delivered in 2010 and 2011 respectively.

The new class represents three of the largest and fastest ATBs in operation today.

The tugs, designed by Naviform in Vancouver, British Columbia, are 148 feet long overall with a beam of 60 feet. For power there are twin Wartsila C32 main engines and controllable-pitch propellers. The propulsion package delivers a total of 16,000 hp and provides for a cruising speed of 15 knots.

The barges, 750-1, 750-2, and 750-3, are all being built in Pascagoula, Miss. The 750-class barges are 45,000 dwt, 600 feet in length, 105 feet 6 inches in breadth and 54 feet 3 inches in depth. The fully loaded draft is 35 feet.

They each have a cargo capacity of 330,000 barrels of petroleum products. When coupled, the tug and barge measure 674 feet in length.

All three ATBs are operated in the Jones Act, U.S. coastwise trade by Crowley’s petroleum services group and bring Crowley’s total ATB fleet to 17, including four 155,000-barrel and 10 185,000-barrel ATBs.
 

Two new ATBs for Kirby

Two ATBs are under construction at Signal International’s Orange, Texas, shipbuilding facility for Kirby Ocean Transport Co., of Houston.

When completed, the tugs Jason E. Duttinger and Captain Donald Lowe Sr. will be coupled to the barges Winna Wilson and Margo Dale. Coupled, the new vessels are over 600 feet overall and priced at about $47 million each.

The new ATBs will replace two tugs and barges in Kirby’s fleet and will service the Atlantic and Gulf coasts hauling dry bulk and break-bulk cargo. Ocean Tug & Barge Engineering of Milford, Mass., designed the tugs and their matched barges.  

The tugs measure 125 feet overall, have a beam of 42 feet and a maximum draft of 22 feet. They are each powered by twin EMD 12-710G7C-TC 3,000-hp engines. The engines turn 135-inch, three-bladed propellers through Reintjes WAF 3455 5.091:1 reduction gears and NautiCan nozzles.

The tugs feature an EMI hydraulic steering system and triple NautiCan rudders. Deck equipment includes a Palfinger 12,125-pound capacity deck crane.

The barges are 490 feet overall with a 90-foot beam and a maximum draft of 36 feet. The barges are equipped with Schottel SRJ220 Pump Jet bow thrusters. The ATBs are fitted with an Articouple KVC-6068 coupling system. Cargo capacity for each barge is 897,905 cubic feet.

The tugs will be ABS classed, Maltese Cross A1/Ocean Towing/SOLAS-ready.
