There are a number of systems available to connect a tug and barge at sea. They vary in experience from many years, to just a few months—from many applications, to just one application. We’d like to introduce you to the most commonly applied systems and some of the newer ones OT&BE has wide experience with many of these systems, and a full understanding of all.

Ocean Tug & Barge Engineering Corp., in partnership with Ship Architects, Inc., is pleased to present the first major rethink of the offshore supply vessel concept in over 40 years – the PROVIDER class AT/B supply vessel.

The COSTWISE class boats are a group of three 12,000 BHP AT/B tugs being built at Bender Shipbuilding for an East Coast marine shipping company.  They will work with a specially-designed 342,000 BBL crude oil lightening barge, also designed by OT&BE.  The tug represents a wholesale change in the design philosophy for AT/B tugs.  Each incorporates features not found on conventional tugs, and for their their size, they are among the most spacious and ergonomically-designed tugs afloat.

OT&BE has also done a number of "everyday" tug and barge related projects, which include:  

  • Repowering
  • Shafting Design
  • Stability Studies
  • Fendering Modifications
  • Upper Pilothouse Additions
  • Tug Rehabilitation
  • Conversions to Yachts
  • Harbor and Towing Tug Design

Still under testing and development, this new idea in escort tugs and assist tugs has had a patent applied for, and features a unique propulsion arrangement that eliminates virtually all the installation problems associated with stern Z-drive arrangements.
