2006-2008

The PATI R. MORAN and her sisters, built at Washburn & Doughty Shipyard, in Boothbay, Maine, are 5100 HP AT/B tugs equipped with the Intercon "C" coupler. Designed to fit the same barge notches as the OT&BE engineered coupler refits on the BARNEY and SCOTT TURECAMO, the ATLANTIC IV class tugs represent a slightly smaller design than the ATLANTIC III, fitted with a full forecastle to create more room, and maintains the efficient single chine hull design of the III, with a slightly narrower beam of 36’.

2007

The CHRISTIANA and her sister, BRANDYWINE, both built at Marinette Marine in Marinette, Wisconsin, represent the second owner of this class tug as well as the second and third versions built.  The tug's hull design was conceived to make it easier to build than her larger ATLANTIC II class sisters, yet at 38' beam, the tug can handle as much as 8,000 RPM.

2005

Provided full contract and detail design for the new COSTWISE CLASS 12000 BHP AT/B tugs for Interorient Maritime/Caspian Maritime to be built in the Caspian Region, and full FEA study of tug structure surrounding Articouple system. Also providing full contract design for the companion 450,000 BBL capacity crude oil shuttle barges, designed in association with CT Marine.

2004

Named for long time Penn Maritime employee Hans Hagen, the CAPT. HAGEN is paired with the double-hulled ocean tank barge KEY WEST.  Both were built at Bay Shipbuilding in Sturgeon Bay, Wisconsin.

2002

The DOROTHY ANN is a 125’, 7,200 BHP AT/B tug built for Interlake Transportation of Cleveland. She works with a former laker, converted to a self-unloading bulk barge, the PATHFINDER (ex-Mauthe).

2001-2002

The SEAHAWK is an 8,000 BHP AT/B tug built for Allied Transportation of Norfolk, VA. She works with a specially-designed 120,000 BBL chemical barge, the ATC 21. Both tug and barge were built at Alabama Shipyard.

2001

The CHRISTIAN REINAUER is paired with the double-hulled ocean tank barge RTC 145, built by Alabama Shipyard in Mobile, AL.  The combination operates along the U.S. East Coast moving clean petroleum products. 

1999

The NICOLE LEIGH REINAUER is paired with the double-hulled ocean tank barge RTC 135, built by Alabama Shipyard, Inc. of Mobile, AL. The combination operates along the US East Coast, moving clean petroleum products. During the winter of 2000/2001, the NICOLE and her near sister, the S/R EVERETT, almost singlehandedly kept Rhode Island stocked with heating oil and gasoline.

1999

K-Sea's LINCOLN SEA (ex-S/R EVERETT) is an 8,000 BHP AT/B tug built for Mobil Oil Corp., US Fleets, then transferred to Sea River Maritime after the Exxon-Mobil merger. She operated the first years of her life in New England, and currently operates along the U.S. East Coast and the Gulf for K-Sea.

1997

Full contract design of the new tug 5,800 BHP SEA EAGLE, built at Halter Moss Point Marine, designed with a Bludworth-type connection system, mated to the earlier-built ocean double hull chemical barge, TMI 80.

In addition, OT&BE has recently designed the following AT/B's, whose projects were not brought to construction, are slated for future bidding, or are awaiting contract signing:  

• BP Amoco - 500,000 BBL Crude Oil AT/B shuttle. This program included full model testing in cooperation with CT Marine, with the companion development of an innovative "SHUTTLETUG" tm design, for use with this barge.
 
• Texaco Pipeline International - Full contract design for a 20,000 DWT AT/B shuttle system for use in the Caspian Sea, including design for both 8,000 BHP tug and double hull tank barge.
 
• Edison Chouest Offshore - Concept study design for the Chouest GOM AT/B shuttle barge and tug.
 
• Dixie Carriers Offshore - Preliminary design of a 30,000 DWT AT/B product carrier, including tug and barge.
 
• Penn Maritime Inc. - Preliminary Design of a 33,000 DWT AT/B product carrier, including a 250,000 BBL double hull tank barge and a 10,000 BHP heavy-fuel AT/B tug.
