Carbonic Gas

Today, there is a strong emphasis on navigation safety in polar waters. IMO Subcommittee on Ship Design and Equipment has issued the Polar Code encompassing the matters of design, structure, equipment and operation of ships intended for polar waters. One of the main objectives of this Code is to work out the rules for man-made pollution management in the Arctic. Modern marine logistics systems developed to transport hydrocarbons and natural gas produced at the Arctic offshore include the ships with high ice class capable of operating both autonomously and with ice-breaker pilotage. This work explains how to assess, as per IMO formulas, the CO2 emissions from large ice-going ships in different scenarios of their ice-breaker pilotage. Obtained results served to assess power efficiency of large ships allowing evaluation of the pilotage techiques, both existing and those suggested by the authors of this paper, in terms of environmental safety.

Drilling Waste

Development of the Russian oil and gas fields in the Arctic requires ensuring industrial and environmental safety of conduct of the operations. Large and unique oil and gas condensate fields are discovered in the southern part of the Kara Sea. The Kamennomysskoye-Sea, Severo-Kamennomysskoye, Semakovskoye, Parusovoye, etc. gas condensate fields are located in the Ob Bay of the Kara Sea. The raw material base of the Severo-Obskoye gas condensate field, unique in terms of the reserves, will become the basis for future Arctic LNG projects. Based on the published data, the initial recoverable total hydrocarbon resources in the Ob and Taz bays are about seven billion tons. Active exploration and commissioning of the already discovered fields require the large volumes of well drilling in a freezing sea, the presence of permafrost, and gas hydrates. During construction of the wells and operation of the offshore ice-resistant oil and gas production platforms, it is required to ensure the disposal of drilling waste (cuttings) and domestic water. There are two technologies for waste disposal — injection into the reservoir or into the clay formations. The first one is used in onshore fields, the second one — on the shelf. Injection into a clay reservoir is successfully used in the Lunskoye gas field on the shelf of the Sakhalin island, and on the Prirazlomnoye oil field in the Pechora Sea. The possibility of using the method and the selection of a reservoir for injecting waste into it requires a geological justification, and the reservoir should ensure a stable injectivity of the required volume. The article presents the results of modeling the injection into the formation of drilling waste, and the waste of the household activities for the Kamennomysskoe-Sea gas condensate field. Calculation was made concerning the zone of absorption of the technological waste into the designed well of the offshore ice-resistant stationary platform. Formation allocation for waste injection was made according to the data of a complex of offshore wells geophysical studies. Three packs of sandy-argillaceous rocks with high reservoir properties were selected as the object of industrial waste disposal. Сalculation was carried out related to the radius of the spread of waste (effluent) in the target reservoir considering drilling and operation of twenty five wells, the construction of which is planned for five years. The results of modeling the process of pumping industrial waste of various types into an absorption well showed that the planned volumes can be successfully disposed of in the selected objects. This will allow to ensure functioning of the marine industry and its environmental safety.

Significant Area

Currently there are no mandatory, internationally accepted rules written specifically to govern ship operations in Arctic waters. The Arctic is recognized by the IMO Guidelines for Ships Operating in Polar Waters as a significant area for international shipping that requires special attention to crew training and operational procedures. A legally binding Polar Code which should identify and unify the commonalities of what it takes, and what is currently enforced by flag states, to safely operate in all Arctic nation waters, is viewed by many as a sensible way forward. This paper presents a synopsis of the results of a funded research project that aimed to identify best practices currently in place by Arctic ship operators. It also aimed to identify possible new ways in which shipping operations in the Arctic could maximize benefits and reduce risks to all stakeholders. A review of the scientific literature clearly highlighted the chasms of knowledge regarding the impacts of marine related activity in Arctic waters. With respect to a methodological approach, a website search was conducted to look for shipping companies informing that they were involved in Arctic operations. The website search of Arctic shipping companies helped with the creation of a questionnaire aimed at identifying “best practices” currently in place with Arctic shipping operators. The questionnaire was administered electronically. Subsequently, a number of companies, identified from the website search and representing a pan-Arctic sample of operators, were contacted by email to inquire if they were interested in taking part in the online questionnaire.

AbstractA new design methodology for long life and large size (Ll-Ls) products called Design for Installation (DfI) is proposed. Ll-Ls products are usually made up of large parts that need to be assembled on field. The proposed methodology, based on adapted Design Structure Matrix (DSM) and Design for Manufacturing and Assembly (DfMA) methods, enables to optimize the design of a Ll-Ls product in order to reduce time and cost of the installation process. The new methodology works with a conceptual design of the product and the weight and size restrictions given by logistic factors as inputs.

This article examines recent legal developments in the management of human activities in Arctic marine areas and considers the extent to which these developments acknowledge or recognize the rights, roles and interests of Arctic Indigenous peoples. These developments include the negotiation of three treaties under the auspices of the Arctic Council: the Agreement on Cooperation on Aeronautical and Maritime Search and Rescue in the Arctic, (Arctic SAR Agreement), the Agreement on Cooperation on Marine Oil Spill Preparedness and Response in the Arctic (Arctic MOSPA), and the Agreement on Enhancing International Arctic Scientific Cooperation (Arctic Science Agreement), the adoption of the Polar Code by the International Maritime Organization (IMO), and, most recently, the signature of the Agreement to Prevent Unregulated High Seas Fisheries in the Central Arctic Ocean (the CAOF Agreement). It also examines more recent practice under the Agreement on the Conservation of Polar Bears (ACPB).

In the context of the melting icecap and the growing shipping activity in the Arctic, the International Maritime Organization (imo) spent several years preparing polar navigation rules aimed at providing appropriate safety and environmental protection standards. The rules underwent several transformations before emerging as the binding International Code for Ships Operating in Polar Waters (Polar Code). The Polar Code is expected to enter into force on 1 January 2017. This paper examines the formation and development of the Polar Code and its principles and provisions, expounds upon the unique characteristics of the Code, and discusses expected future practices.
