Provided engineering and design for the previous refit of the ocean tug PAUL T. MORAN (Ex. OCEAN VENTURE) with a Bludworth connection system, and the refit of the stern of the ocean tank barge MASSACHUSETTS, for use with the Bludworth system, with full FEA study.
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.
The RUTH M. REINAUER represents a new concept in AT/B design. Equipped with double skin fuel tanks, the first on a boat her size, the RUTH features our new "FacetTug" hull shape with is designed to make double skin fuel tanks in small vessels easier to install and also allows the tug to be built in panel lines, or in less sophisticated yards in developing countries, that do not have the extensive plate forming and bending capabilities.
Engineered the refitting of both the 7,200 BHP tug and the 30,000 DWT ocean tank barge with the Intercon system. This unit is still in service today and is slated for refit with a double-hull. The tug LIBERTY is currently working with a modified INTERCON system for lightering which we also engineered – see below. Provision of a full FEA study for the connection-related structure on both the tug and barge for an East Coast shipping company.
Engineered the refitting of both the 5,750 BHP tug and the 31,000 DWT ocean tank barge with the Intercon system. This unit is still in service today and is has recently been refit with a double-hull. An East Coast shipping concern.
Engineered the refitting of both the 5,750 BHP tug and an 31,000 DWT ocean tank barge with the Intercon system. The barge was lost in a collision and fire in Tampa in 1994, but the tug was reassigned to the barge OCEAN 244. This validated the philosophy we advocate, of making tugs interchangeable. OT&BE provided a full FEA study for the connection-related structure on both the tug and barge for an East Coast shipping company.
Providing engineering and design for the coupler refit and repowering of the ocean tug CRAIG ERIC REINAUER (ex EL BRONCO GRANDE) with an Intercon “C” connection system.
Engineered the very first installation of an Intercon system aboard a tug/barge unit. This was a refit to existing vessels, with a 5,750 HP tug and 31,000 DWT ocean tank barge. This unit is still in service today on the Gulf Coast, and was refit with a double hull in 2002. The refit also involved a significant model-testing program conducted jointly with CT Marine, at the MARIN basin. Provision of a full FEA study for the connection-related structure on both the tug and barge.
Providing engineering and design for the refit of the ocean tug BRIDGET MCALLISTER, with an Intercon “C” connection system, FEA, and design of a new tower pilothouse. McAllister Brothers.
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"™ 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.
