Sea Going Modular Vessel - Economically & Efficiently Transports Goods by Water    

Modular tanker vessel for ocean transportation of cargo, such as oil or other.


A barge train or modular tanker vessel is for ocean transportation of cargo, such as oil or other dry or liquid materials, it includes a forward traction unit, a rear powered caboose unit and a series of modular units or barges interposed there between. The units are flexibly interconnected by means of a universal type coupling and are detachable.

Primary Application of the Technology

Marine oil transportation
Container Feeder

The Problem Solved by the Technology

The patented invention seeks to provide a less expensive method of shipping cargo by sea or water ways by solving the problem of flexibly connecting a series of barges in such a way as to:

1. Maintain hydrodynamic continuity which dramatically reduces drag and hence power requirement.

2. Eliminate the wave bending stresses that normally limit the length of a ship and thus reduce the needed amount of steel for hull girder strength

How the Technology Solves the Problem

The problem is solved by the development of the patented universal connection system. Constructing and operating a barge train type vessel requires a much smaller dry dock facility for construction than is required for present day tankers of comparable capacity, it can be accommodated in channels and harbors which are much smaller and shallower than those required to accommodate a tanker, and can pass through artificial waterways such as the Panama and Suez Canals.

Competitive Advantage

The advantages of this modular concept for moving bulk cargo are analogous to the advantages of the railroads, without the disadvantage of being restricted to established railroad tracks. In another sense the patented invention also has some of the advantages found in the container ship concept. The ship does not have to wait while the containers are being filled or emptied, it merely delivers the full containers and picks up the empty ones.


The cost of the ship is estimated to be about 20% lower than a conventional tanker. The reason being that the ship is flexible and consequently is subject to lesser wave bending moments in the individual hulls, therefore requiring less steel for hull girder strength.

The building of the barges and the traction units does not require huge specialized shipyards. A 260-foot length is workable for any shipyard.

The cost of operating the ship is competitive in fuel.

The power requirement is slightly less than in a conventional tanker and greatly less than in an (ITB) integrated tug-barge system, which is weather, restricted.

The cost of operating the ship is about 25% lower in crew than in a tanker - he barges are unmanned.

The accessibility to the number of harbors is vastly expanded due to the relative low draft and beam.

The access to limited dock space for loading and unloading is greatly increased.

The loss in down time for periodic maintenance is eliminated the units are sent to maintenance and replaced on a rotational schedule

The time loss in loading and unloading is reduced to a fraction of what it is at present - the drop and swap method of delivery insures short turn around time.

Safer in case of collision - the damage will be restricted to one barge. You do not loose the ship

Safer in case of fire - the burning module can be quickly isolated by the quick disconnect mechanism.

Redundancy in the case of a power failure in the traction unit - the rear unit takes over.

Passage through restricted waterways.

Versatility - the size of the ship (number of units in train) is adjusted to the commercial needs of the carrier tanks.

Temporary floating storage tanks in harbors or at the base of offshore drilling rigs

Environmentally safer - limited damage to a particular barge.
