The second shallow-draught icebreaking tug of TG04M project was put into operation for OJSC "MMC "Norilskiy Nikel"
On July 17, 2012 shipyard "Nizhegorodskiy Teplokhod" (Bor, Nizhniy Novgorod, Sergey Konovalov is a general director) put into operation the second shallow-draught icebreaking tug "Portoviy-2" of TG04M project for OJSC "MMC "Norilskiy Nikel".
The TG04M project was designed by the Marine Engineering Bureau.
The new tug boat is assigned for:
• roadstead-maneuvering works with river going vessels and floating cranes;
• auxiliary works such as berthing, unberthing, handling of barges and vessels;
• vessels' placing in backwater during spring flood;
• placing of non-self propelled fleet for winter stand (placing over a distance from berth in autumn ice with holding until vessel freezes in).
A lot of "Neva-2009" visitors could watch film (stand of "Nizhegorodskiy Teplokhod" shipyard), that illustrated absolutely unique maneuvering qualities of "Portoviy 1", including "police U-turn" (terminology of motor-car enthusiasts).
Self-propelled dry-cargo vessels and tankers and also non-self-propelled barges have been built for river and river-sea going transportations for last years, as a rule. These objects directly transport the cargo ("earn").
At the same time existing tug fleet continues becoming out of date steadily. There were 55 vessels with the age up to 10 years, 101 vessels with the age from 10 to 15 years, 972 vessels with the age from 15 to 20 years, 2517 (!!!) vessels with the age from 20 to 30 years and 3119 (!!!) vessels with the age more than 30 years with the RRR class at the beginning of 2008.
Though in the river ports necessity of the new tug boats is very high due to extremely decrepitude of existing fleet.
The tugboats of TG04 and TG04M prjs. series are the first of the new generation of river tugs and pushers that are built for operation into Russian internal waterways.
Tugboat features are as follows:
• tug is designed for operation at extremely low outer air temperature;
• equipment and construction of the propulsion complex permit to put tugboat into operation at extremely low temperature from condition of full into-ice freezing;
• tug's hull is of reinforced type for operation in the conditions of freeze basin;
• tug's weight does not exceed 100 t for providing ability to raise tug onto berth for the winter stay;
• tug's maximal draught does not exceed 1.80 m;
• tugboat is able to fulfill works due to providing port fleet safety during ice shifting, so her overall dimensions should me of minimal type.
The project was designed for RRR class notation of O 2.0 (ice 30) A. Ice category is assigned higher that recommended by RRR Rules for vessels of "O 2.0" type.
