Expert Council of RosMorRechFlot accepted ICV51 concept of Arc 7 container vessel for the Northern Sea Route with 3000 TEU capacity

ICV51 concept of the 45 MW Arc 7 container vessel for the Northern Sea Route (NSR) with 3000 TEU capacity was presented at a meeting of Expert Council of Maritime and River Fleet Federal Agency of Russian Federation; Acting Head of the Agency Sergey Gorelik was a chairman.
Concept's development was carried out by JSC CSRI (researches, including study of operation models for container vessel at NSR depending on loading degree, type of icebreaking service, type of vessel's fuel; preparation of comparative technical-economic calculations, definitions of optimum characteristics of vessel's basic variant, the technical-economic justification of concept) together with Marine Engineering Bureau (preliminary and technical projects).
Work was fulfilled due to request of RosMorRechflot.
At the meeting, Arctic container vessel concept was introduced by the General Director of the CSRI Sergey Buyanov. A number of high-ranking men took part in the discussion, as follows: Acting Head of the RosMorRechFlot Sergey Gorelik, Deputy of the Head of the RosMorRechFlot Victor Vovk, President of the "Russian Chamber of Shipping" Union Alexey Klyavin, Deputy of the General Director of the Krylov State Scientific Center Oleg Timofeev, General Director of the Marine Engineering Bureau Gennadiy Egorov.
The ICV51 arctic container vessel of unrestricted navigation area is a single deck motor-electric vessel with 5 cargo holds, with forecastle and poop, with lowered aft mooring deck, with living deck-house and ER located aft, with 3 aft full-turn Azipod rudder propellers, with double bottom and double sides, with ice-breaking fore end and transom aft end, with stern crinoline with cutout for vessel pushing, with pontoon type hatch covers (removing ones), with fore bow thruster.

Russian Maritime Register of Shipping class notation is KM Arc7 PC3 AUT1-ICS OMBO EPP ANTI-ICE ECO-S WINTERIZATION(-40) Container ship.
Ice-passing capability of the new concept is not less than 2.1 m for head running as well as for astern running. Escape from own canal and half-round turn by "star" method are provided.
Fore contains enhanced traditional ice-breaking contours (stem inclination is 25°, DWL sharpening is about 35°, flam of the 0-2 theoretical frames is 55-36°). Aft end contours are of ice-breaking type. There are aft crinoline with towage cutout for providing ability of vessel's pushing by another ice-breaker in ice. Shape and construction of crinoline are accepted for work with K-60 ice-breaker.
Vessel is designed in accordance with IACS Unified Interpretations for the polar type vessels with PC3 class, providing additional strength reserve compare to RS Arc 7 class. This should provide the whole-year navigation through two-year ice that contains multiyear ice. Besides the damage stability of the vessel is ensured for ice damages that may cause flooding of any two adjacent side compartments.
Vessel's hull is divided into 5 cargo holds in the cargo zone. It has double bottom and double sides, upper deck with opening 0.876 of the vessel breadth, uninterruptable longitudinal hatch coamings of 2.10 m height. RS Rules requirements for unrestricted navigation vessels with big deck opening are met with 10.9% reserve due to normal stress criterion and with significant reserve due to lengthening criterion for hatch cutout diagonals.
Upper deck, inner sides, upper part of outer sides, bottom and double bottom are designed by the longitudinal framing system, other hull parts are designed by transverse framing system.
High grade D36 shipbuilding steel (yield strength 355 MPa) is used as a material for main hull structures except ice belt of outer shell, longitudinal bottom stiffeners, frames, diaphragms, floors and bottom stringers in the ends; E500 steel (yield strength 500 MPa) is used for the pointed elements.
Side and bottom ballast tanks are foreseen for the vessel; their total capacity is 22000 cub.m. Ballast tanks provide vessel's normal trim for all specified loading cases.
Double bottom height is 2000 mm. Side tanks breadth is 2000 mm.
Power outlets for 400 refrigerator TEU and 200 refrigerator FEU are foreseen on the on upper deck. 45 ft. containers are arranged on the open deck.Electric propulsion plant consists of three 15 MW full-turn Azipod rudder propellers equipped with FPP.
Range of sailing is 15000 miles. Vessel's autonomy is: 30 day due to fuel reserve, 90 days due to dry provision reserve, 60 days due to other provision and fresh water reserve.
Bow thruster of "screw in a tube" type with capacity of about 1400kW is foreseen for increasing of low speed controllability during passing locks and during mooring.
Main diesel-electric power plant consists of 6 main AC 11200 ekW diesel-generators (11 kV, 50 Hrz) that serve main vessel's electrical network including propulsion unit.
Auxiliary power plant consists of AC 1140 ekW harbor diesel-generator (HDG) (400 V, 50 Hz), AC 1081 eKW emergency diesel-generator (400 V, 50 Hz), auxiliary boiler plant consisting of two 5000 kW thermal oil heaters and six 1665 kW (85% loading) thermal oil economizers.
Removing pontoon type hatch covers are foreseen. Hatch cover sections are handled by shore cranes.
Container cell guides are arranged within cargo holds.
Two fore anchor-mooring winches and two aft mooring ones are foreseen for mooring operations. They provide automatic tension and unwinding of mooring ropes.
