Rosatom develops new direction for Russian shipbuilding
Atomenergomash (Rosatom's machine building division) has developed projects for semi-submersible heavy transport vessels of Arc5 and Arc7 class for carrying extra-heavy and oversized cargo under arctic conditions. This was reported by the Director on Shipbuilding and Fighting Against Economic Crimes of JSC Atomenergomash Vladimir Aptekarev. He has also stated that such vessels are absolutely new for the Russian shipbuilding industry.
The projects are jointly implemented with the partners - JSC Atomenergo and the Finnish company Aker Arctic Technology Inc. "Vessels of this type are designed to move large, extremely heavy cargoes, such as sections of offshore platforms and oil platforms, other ships and vessels, cranes, jetties, etc. Today, Russian fleet operators have no such vessels, though there is a need for transportation of drilling platforms and other heavy equipment in the Russian Arctic zone, - said Mr Aptekarev. He has emphasized that these ships may use the Northern Sea Route for transit between Europe and Asia, or Asia and Europe, but their main purpose is servicing Fuel & Energy Complex projects in the Arctic zone of the Russian Federation.
In terms of deadweight (total weight of cargo, including fuel, water, passengers, crew, etc. which amont about 70,000 - 75,000 tons) such vessels are in the top five largest ships in the world. They differ from their foreign counterparts primarily by their ice Arc5 and Arc7 class, which allows using them on the Northern Sea Route, as well as by ability to operate in dual fuel mode, which corresponds with the current decarbonization trend.
Semi-submersible heavy transport vessels represent the most common type of heavy transport vessels with an open cargo deck and a bow superstructure. The engine room and living quarters are forward of the vessel. In this configuration, the engine room is located at the level of the upper deck. Technical proposals are prepared taking into account the requirements of Rules for the Classification and Construction of Sea-Going Ships of Russian Maritime Register of Shipping. Conceptual variants are designed for minimum ambient air temperature at 50 degrees Celsius below zero.
