The train is comprised of a pusher tug and a barge coupled by means of the FC-38SM articulated coupling system manufactured by Taisei Engineering Consultants Inc., Japan, which has undeniable advantages over the earlier systems: a barge + a tugboat or a self-propelled oil tanker (or dry cargo ship).
Class notation of the barge according to the Russian Maritime Register of Shipping: KE R3-RSN Oil tanker.
Class notation of the pusher tug according to the Russian Maritime Register of Shipping: KM R2-RSN Ice 2 AUT 3 Tug.
MAIN ADVANTAGES OF THE PROPOSED TUG AND BARGE TRAIN OVER SELF-PROPELLED TANKERS (OR DRY CARGO SHIPS) ARE:
- lower construction costs at similar cargo carrying capacity;
- greater survivability and safety for the crew and the property in case of emergency;
- the opportunity to use the pusher tug or the barge while either part of the train is being repaired or loaded, which improves the economic efficiency;
- lower repair costs due to less stricter requirements of the Russian Maritime Register of Shipping and the Russian River Register to separate elements of the train, i. e. a pusher tug and a barge;
- the assigned class enables the train to navigate the sea;
- the articulated coupling of the barge and the pusher tug decreases the breaking load on the hull (risk of fracture) and increases the service life;
- the overall length of the train at 139.33 m allows to use the effective tank volume to the maximum and pass through all lock systems in Russia.
