A foundation-laying ceremony for an ice-resistant platform (ICP) of Gazprom, which shall be used within the growth of the Kamennomysskoye-Sea area, occurred on the shipyard of Southern Shipbuilding and Repair Center within the Astrakhan Region.
The area is exclusive when it comes to its gasoline reserves, which quantity to some 555 billion cubic meters. Production operations are as a consequence of begin in 2025, with a design output (for Cenomanian deposits) of 15 billion cubic meters per 12 months.
The area is located in a marine setting characterised by low temperatures (as much as minus 60 levels Celsius), heavy storms, shallow depths (5–12 meters), and thick and dense freshwater ice. The growth of this area will turn out to be the primary shelf mission on this planet to be carried out in such excessive ice and local weather circumstances.
In view of those components, it was determined to make use of a particular ice-resistant platform as the important thing facility within the growth of the sphere. The platform shall be greater than 135 meters lengthy, 69 meters huge, 41 meters tall from the bottom to the helicopter pad, and its weight will exceed 40,000 tons in complete. The buildings positioned on the platform will embrace, inter alia, predominant and auxiliary drilling modules, operational and power complexes, and residing quarters for 120 individuals. The ICP shall be used to construct 33 predominant directional manufacturing wells (afterward, one other 22 wells for sustaining manufacturing charges shall be positioned on satellite tv for pc ice-resistant conductor platforms that don’t require everlasting presence of personnel). The extracted gasoline shall be fed into pipelines and arrive onshore right into a complete gasoline therapy unit and a booster compressor station. After that, the gasoline will go into Russia’s Unified Gas Supply System.
The full scope of modeling and design for the ICP was carried out by Russia’s main shipbuilding analysis establishments. The building course of will contain a variety of cutting-edge technical options to make sure a excessive stage of commercial and environmental security, in addition to operational integrity of the power. For occasion, to guard the ICP from thick ice, the assist construction shall be V-shaped, and practically the entire facility’s gear shall be encased within the hull and thus protected against chilly and wind. The ICP shall be firmly fastened on the muddy backside of Ob Bay with the assistance of a piled gravity base basis: the platform shall be positioned on the seabed, the underwater a part of the ICP shall be stuffed with seawater after which fastened in place with 56 piles greater than 2 meters in diameter, pushed 47 meters into the seabed.
Particular consideration within the mission is paid to options aiming to stop opposed impacts on the Arctic wildlife. This features a zero discharge system: all family and manufacturing waste shall be faraway from the platform and disposed of later.
In order to construct a facility of this technological complexity, a number of Russian shipbuilding and machine-building facilities are offering their capacities in response to the ‘distributed shipyard’ precept. Separate parts of the platform shall be concurrently put collectively in Astrakhan, Kaliningrad, Severodvinsk, Yekaterinburg, and Rybinsk. The ICP shall be lastly assembled in a single piece in Kaliningrad. In the summer time navigation interval of 2024, it’s deliberate to tow the ICP to the sphere, after which flare booms and a helicopter pad shall be arrange on the facility.
