Although transport of goods by sea freight is far more efficient than by any other means, the global trend is to reduce emissions on all transports. New rules such as the Energy Efficiency Design Index, the Polar Code and the EU Sulphur emissions directive will regulate shipbuilding in the future. The Aker Arctic DAS® double-acting concept solves both emission and propulsion requirements. Our idea when we develop new vessel concepts is to find ways to do the same work with higher efficiency and smaller engines. The IMO Energy Efficiency Design auxiliary systems used in icebreaking clean and energy efficient. A good Index (EEDI) came into force 1st situation e.g. air bubbling systems.

First, it conducts a survey of past and present Northern Sea Route (NSR) cargo flows. Then follow discussions of the route’s commercial potential as a transit route, as well as of its economic importance and relevance for each of the Russian Arctic regions. These discussions are summarized by estimates of what types and volumes of NSR cargoes that can realistically be expected in the period 2000-2015. This is then followed by a survey of the status quo of the NSR infrastructure (above all the ice-breakers, ice-class cargo vessels and ports), with estimates of its future capacity. Based on the estimated future NSR cargo potential, future NSR infrastructure requirements are calculated and compared with the estimated capacity in order to identify the main, future infrastructure bottlenecks for NSR operations. The information presented in the report is mainly compiled from data and research results that were published through the International Northern Sea Route Programme (INSROP) 1993-99, but considerable updates have been made using recent information, statistics and analyses from various sources.

  • Russia's Akademik Lomonosov – the First Modern Floating Nuclear
    Russia’s Akademik Lomonosov – The First Modern Floating Nuclear Power Plant (FNPP) Peter Lobner, 15 May 2021 1. Introduction Designated Project 20870, construction of Akademik Lomonosov started on 15 April 2007, when the keel was laid at the Sevmash shipyard in Severodvinsk, which also is Russia’s premier submarine building shipyard. Originally, Akademik Lomonosov was expected to supply power to the Sevmash shipyard itself and the town of Severodvinsk, in Northwest Russia. Cutaway drawing showing the general arrangement of the Akademik Lomonosov. Source: Rosatom In August 2008, the hull of Akademik Lomonosov was transferred to the Baltic Shipyard in St. Petersburg, where a second “keel laying” was held in May 2009. Plans for deploying the FNPP were reconsidered, leading to the final selection of Pevek, a remote Arctic coastal city in Russia’s Far East. The FNPP was launched on 30 June 2010 and outfitting continued with the vessel secured dockside at the Baltic Shipyard. Two un-fueled OKBM Afrikantov KLT-40S modular pressurized water reactors (PWRs) were installed in October 2013. 1 After work on the vessel and reactor systems was completed in April 2018, Akademik Lomonosov was towed 4,000 km (2,485 miles) around Norway to Murmansk, where the reactors were fuelled and tested at Rosatomflot facilities, which also support their nuclear- powered icebreaker fleet. In June 2019, the Russian nuclear regulatory agency Rostekhnadzor issued a 10-year license to Rosenergoatom to operate Akademik Lomonosov until 2029. After successfully completing testing, Akademik Lomonosov departed Murmansk on 23 August 2019 and was towed 4,770 km (2,964 miles) along the Northern Sea Route, arriving at its final destination on 9 September 2019 at a new protected pier at Pevek, which is about 980 km (609 miles) west of the Bering Strait.

Jakob Belter ([email protected]) Abstract. Changes in Arctic sea ice thickness are the result of complex interactions of the dynamic and variable ice cover with atmosphere and ocean. Most of the sea ice exits the Arctic Ocean through Fram Strait, which is why long-term measurements of ice thickness at the end of the Transpolar Drift provide insight into the integrated signals of thermodynamic and dynamic influences along the pathways of Arctic sea ice. We present an updated time series of extensive ice thickness surveys carried 5 out at the end of the Transpolar Drift between 2001 and 2020. Overall, we see a more than 20% thinning of modal ice thickness since 2001. A comparison with first preliminary results from the international Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) shows that the modal summer thickness of the MOSAiC floe and its wider vicinity are consistent with measurements from previous years.

  • Western Sanctions Will Affect Russian Shipbuilding
    WESTERN SANCTIONS WILL AFFECT RUSSIAN SHIPBUILDING Western sanctions will not hamper construction of nuclear icebreakers, but can have negative consequences for other Russian civilian shipbuilding. Western sanctions could curb Russian Arctic oil Statoil, Rosneft delay Siberian drilling, while CEO Sechin added to international sanction list This week the U.S. and EU hardened its sanctions against Russia designed to punish its continuing backing of separatists in Eastern Ukraine. The sanctions include the EU banning any trade in arms and the US prohibiting transactions with Russia’s United Shipbuilding Corporation, which it classified as a defense company. According to the United Shipbuilding Corporation the sanctions will probably have no impact on state orders that already are under construction, but can seriously hamper future orders. The Baltic Shipyard outside St. Petersburg has orders to construct Russia’s three next, much-needed nuclear-powered icebreakers. The prototype was laid down in November 2013 and is planned to be ready for service in December 2017. The two next icebreakers should be ready for delivery in 2019 and 2020. “We don’t see any problems in the construction of the nuclear icebreakers, since no part of the equipment - down to the last bolt and screw – has anything to do with the U.S.” a spokesperson from United Shipbuilding Corporation says to Arctic Info. Others are not so optimistic about the future of civilian Russian shipbuilding after the last sanctions were imposed. Head of St. Petersburg’s Committee for Industrial Policy and Innovation Maksim Meyksin says to website Baltpp that the sanctions can have serious impacts on the large shipyards in the region.

Presented by Vassily A. Spiridonov (P.P. Shirshov Institute of Oceanology of Russian Academy of Sciences, Moscow), Maria V. Gavrilo (National Park “Russian Arctic”, Arkhangel). Abstract (in less than 150 words) The system of polynyas in the Laptev Sea and specific conditions of the waters of New Siberian Islands form ecologically and biologically significant area with medium level of uniqueness, high level of importance for life history stages of key or iconic species, medium level of importance for endangered or threatened species, medium (at the scale of the Arctic) levels of biological productivity and diversity and high vulnerability. Introduction (To include: feature type(s) presented, geographic description, depth range, oceanography, general information data reported, availability of models) Polynyas in the Russian Arctic have been recognized as extremely important for ecosystem processes and maintaining biodiversity (Spiridonov et al, 2011). The IUCN/NRDC Workshop to Identify Areas of Ecological and Biological Significance or Vulnerability in the Arctic Marine Environment (Speer and Laughlin, 2011) identified Super-EBSA 13 “Great Siberian Polynya” that can be divided into two “elementary” EBSA 33 (Great Siberian Polynya proper) and 35 (Waters of New Siberian Islands) (Speers and Laughlin, 2011). The report on identifying Arctic marine areas of heightened ecological significance (AMSA) also revealed these areas (Skjoldal et al., 2012: fig. 7).

  • Marine Nuclear Power: 1939 – 2018
    Marine Nuclear Power: 1939 – 2018 Part 3B: Russia - Surface Ships & Non-propulsion Marine Nuclear Applications Peter Lobner July 2018 1 Foreword In 2015, I compiled the first edition of this resource document to support a presentation I made in August 2015 to The Lyncean Group of San Diego (www.lynceans.org) commemorating the 60th anniversary of the world’s first “underway on nuclear power” by USS Nautilus on 17 January 1955. That presentation to the Lyncean Group, “60 years of Marine Nuclear Power: 1955 – 2015,” was my attempt to tell a complex story, starting from the early origins of the US Navy’s interest in marine nuclear propulsion in 1939, resetting the clock on 17 January 1955 with USS Nautilus’ historic first voyage, and then tracing the development and exploitation of marine nuclear power over the next 60 years in a remarkable variety of military and civilian vessels created by eight nations. In July 2018, I finished a complete update of the resource document and changed the title to, “Marine Nuclear Power: 1939 – 2018.” What you have here is Part 3B: Russia - Surface Ships & Non-propulsion Marine Nuclear Applications.

  • 22 IAHR International Symposium on Ice Floating Ice Induced Ship Casualties
    22nd IAHR International Symposium on Ice Singapore, August 11 to 15, 2014 Floating Ice Induced Ship Casualties Nataliya Marchenko The University Centre in Svalbard, Longyearbyen, Norway State Oceanographical Institute, Moscow, Russia Postbox 156. Longyearbyen N-9171, UNIS [email protected] It is very important to analyze sea-ice-induced ship casualties because transport activity at high latitudes is growing. A significant search is underway for an Arctic alternative to the southern (Suez) route from Europe to Asia. However, despite global warming and forecasts of an ice-free Arctic, ice conditions are still rather difficult. The Vilkitsky Strait was closed by ice for almost the entire navigation season 2013. Several accidents occurred, including the rupture of a tanker by an ice floe, nipping and overwintering last year. The frequency of ship casualties in the Polar regions is much smaller than in the world ocean. But due to a low self-purification capacity of Arctic and Antarctic nature and harsh weather conditions, we should try to avoid any type of failure and minimize the risks involved. An analysis of ship accidents caused by sea ice in the Russian Arctic over the previous century (Marchenko, 2012) shows that a majority of casualties were related to floating ice. In significant number of cases, the accidents could be avoided if captains took into consideration sea ice properties, distinguished between “strong ice” (multiyear ice, icebergs) and “soft” first year ice. In this article, several cases on serious casualties with floating ice are presented. These cases include incidents with holing of the icebreaker Admiral Lazarev (1965, East Siberian Sea), the cruise ship Maxim Gorkiy (1989, Greenland Sea) and the tanker Nordvik (2013, Kara Sea); sinking of the adventure vessel Explorer (2007, South Ocean) and freighter Nina Sagaydak (1983, Chukchi Sea), nipping and drift of several vessels in Okhotsk Sea (2010-2011, 2013-14,) and Akademik Shokalskiy (2013-14, South Ocean).
