The support vessel "Irbis" of the MRS towed CNF11CPD ferry "Alexander Deev" from the water area of Amur aber to the port of Vladivostok

According to Marine Rescue Service's website, "Irbis" support vessel's crew of the Primorsky branch of the FSBI "Marine Rescue Service" coped well with difficult towing of CNF11CPD car-railway-cargo-passenger new generation ferryboat from the Amur aber to the port of Vladivostok.
Plant-builder - Amur shipyard (Komsomolsk-on-Amur, general director Vladimir Kulakov).
The customer is PJSE "State Transport Leasing Company".
Project documentation for the vessel under construction was developed by the Marine Engineering Bureau, working-design and technological documentation by Vympel Design Bureau.
During the passage "Irbis"-"Alexander Deev" was accompanied by the sea tugboat "Vostok".
CNF11CPD ferry was handed over to the customer, "Irbis" returned to his daily tasks.
The support vessel "Irbis" was at sea for more than two weeks. During this time were covered 1189 nautical miles, most of them in tandem with the towed object. Leaving the port of Korsakov, "Irbis" headed for the Southern fairway of the Amur aber, where CNF11CPD ferry "Alexander Deev" was taken on tow after comprehensive and thorough checks on facility's readiness for towing.
Already on the second day of transition, the towing continued as planned despite the deteriorating weather. The towing pair was sailing at a cruising speed of 3-3.5 knots. No emergency situations occurred during the towing period. "Irbis" crew, under the leading of captain S.V. Tupolenko, professionally coped with the tasks of transporting a complex and large-sized object.
It is enough to refer to the numbers to represent object's dimensions towed by "Irbis": the length of CNF11CPD ferry is more than 100 meters, the width is 22 meters, the deadweight is 7,250 tons; the vessel has three cargo decks each, which can accommodate 32 railway vans, 48 cargo articulate lorries and 28 passenger cars and 200 seats for passengers.
According to the shipyard, now the ferry of the CNF11CPD project "Alexander Deev" has 64% readiness, the main mechanisms are installed on it, about a hundred kilometers of the main cable are pulled. The vessel is equipped with a freight elevator, side ramp, stern ramp, and outboard ladders. Most of the devices have already been installed, tested and accepted by the customer and the Register. On the delivery base, work is to be done on the formation of rooms within the order, testing and painting of ballast tanks, installation of stern and side devices, freight and passenger elevators. This will be followed by preparation and carrying out of mooring tests.
The launch of the fully formed hull of the second ferry of the CNF11CPD project "Vasily Oshchepkov" is scheduled for autumn 2020.
CNF11CPD project of the car-railway-cargo-passenger new generation ferryboat for the Vanino-Kholmsk line provides in comparison with the existing "Sakhalin" type vessels:
• enhanced cargo capacity (truck cars capacity is 2 times bigger);
• weather restrictions absence (unrestricted sailing region);
• ability of working in severe ice conditions (speed is 6-8 kn at 80 cm ice and about 3 kn at 1.0 m ice);
• ability to carry out independent (several times per day) moorings without towing assistance, ability for long reverse movement through constrained water area of the port of Kholmsk;
• ability to keep up daily cycle of round voyage (operation speed is 18 kn);
• 2-hours staying for loading-unloading operations.
Transportation is foreseen of at least of 32 railway wagons or 27 car trains on the main deck, 12 car trains on the lower deck and about 9 cars (1.5 tons).
The new CNF11CPD ferry boats will allow the Sakhalin producers to forward products to the mainland in time; will provide food security and expand possibility of transportation for certain types of cargo.
The number of passengers (200 people) accepted in the new project reflects the peak line need at a season of summer vacations and is set according to the offer of the Sakhalin Region Government; it is essentially important to provide solving of a social problem of recreation providing for the region's population 200 passengers distribution is as follows: 16 ones at double cabins with water closets, 96 ones at four-berth cabins with water closets and 88 ones at saloon chairs.
The new concept is the result of a series of studies conducted in 2012-2013 by the Marine Engineering Bureau in collaboration with leading domestic and foreign scientific institutes, including Aker Arctic Technology (recommendations for contours, tests in the ice pool), Central Research Institute of the Marine Fleet (examination of technical solutions for all stages, formation of contours, economic calculations and modeling of operation), Krylov State Scientific Center (towing tests, self-propelled, nautical, as well as testing in ice basin), design bureau of the carriage facilities of JSC Russian Railways (checking the possibility of transporting rolling stock by ferry).
CNF11CPD characteristics in ice conditions according to the results of tests in the pool are: the maximum ice permeability at V = 3 knots forward will be 1.16 meters, at a speed of V = 6 knots it will be 0.84 meters, in reverse with a speed of V = 1.5 knots will be 0.68 m.
In addition, the bow and stern extremities are structurally designed for a higher ice category (Arc 7).
Together with the icebreaking at the level of the Icebreaker6 icebreaker, this allows (unlike the existing vessels) independent operation of the new ferry in severe ice conditions on a short passage (up to about 30 miles in the vicinity of Vanino). In turn, this will allow to avoid ferry's significant downtime in anticipation of general icebreaking assistance, or excessive costs in case of individual assistance.
At one time, the ferry was built to serve the railway transportation, but recently, the increasing part of the ferry routes began to take the vehicles transport. A new type of cargo (heavy trailers (trucks) and cars) has appeared. In connection with the construction of the Lidoga-Vanino highway, the share of road transport will increase. In addition to transporting cars and trailers, shippers have another potentially new type of cargo for the ferry line: containers and roll trailers with heavy equipment. Therefore, while maintaining the function of transporting railroad cars (the length of rail tracks is 440 linear meters at 420 on the existing one), the capacity for cars has doubled (740 linear meters against 394 on the existing one). As a result, 39 new trucks with semi-trailers (12-13.5 m length) and an additional 9 cars can be accommodated on the new vessel.
In addition to the stern cargo handling scheme, which is definitely tied to the ports of Vanino and Kholmsk terminals, an on-board ramp is installed for working with rolling equipment directly to the pier, which allows the use of a new vessel (for example, for commercial flights to Japan).
The keel of the lead CNF11CPD vessel (building No. 00300) "Alexander Deev" was laid down on 29.0617. She was launched on 01.08.2019.
The keel of the second vessel (building No. 00301) "Vasiliy Oshepkov" was laid down on 29.06.2017. Launch is planned on autumn 2020.
