據(jù)離岸工程6月26日報(bào)道，俄羅斯天然氣工業(yè)股份公司為開發(fā)Kamennomysskoye-Sea油田而建造的防冰海上生產(chǎn)平臺周四在位于阿斯塔罕地區(qū)的南方造船和修理中心(聯(lián)合造船公司的一部分)開始建設(shè)。

Kamennomysskoye-Sea氣田位于喀拉海的Ob灣，那里的氣溫可以降至零下60攝氏度。該氣田的天然氣儲量巨大，約為5550億立方米。該公司預(yù)計(jì)在2025年開始生產(chǎn)，設(shè)計(jì)產(chǎn)能為每年150億立方米。

俄氣表示，該油田所處的海洋環(huán)境特點(diǎn)是低溫、強(qiáng)風(fēng)暴、淺水(5-12米)和厚而密的淡水冰。這一領(lǐng)域的開發(fā)將成為世界上第一個(gè)在如此極端的冰雪和氣候條件下實(shí)施的陸架項(xiàng)目

俄氣目前正在為該油田的開發(fā)建造一個(gè)特殊的抗冰平臺。平臺長135米，寬69米，從基地到直升機(jī)坪高41米，總重量將超過4萬噸。平臺上的結(jié)構(gòu)將包括主要和輔助鉆井模塊、操作和能源綜合設(shè)施以及可容納120人的生活區(qū)。

該防冰平臺將用于建造33口主定向生產(chǎn)井(隨后，將在不需要人員永久駐留的防冰導(dǎo)體平臺上再部署22口井，以維持產(chǎn)量)。抽取出來的天然氣將通過管道輸送到岸上，進(jìn)入一個(gè)綜合天然氣處理裝置和一個(gè)增壓壓氣站。之后，天然氣將進(jìn)入俄羅斯統(tǒng)一供氣系統(tǒng)。

Gazprom Starts Construction of Arctic Offshore Platform

Construction of Gazprom's ice-resistant offshore production platform for the development of the Kamennomysskoye-Sea field began Thursday at the shipyard of Southern Shipbuilding and Repair Center (part of United Shipbuilding Corporation) in the Astrakhan Region.

The Kamennomysskoye-Sea gas field is located in the Ob Bay of the Kara Sea where temperatures can drop to minus 60 degrees Celsius.

"The field is unique in terms of its gas reserves, which amount to some 555 billion cubic meters. Production operations are due to commence in 2025, with a design output (for Cenomanian deposits) of 15 billion cubic meters per year," Gazprom said.

The field is situated in a marine environment characterized by low temperatures, heavy storms, shallow depths (5-12 meters), and thick and dense freshwater ice, Gazprom said.

"The development of this field will become the first shelf project in the world to be implemented in such extreme ice and climate conditions," Gazprom said.

Gazprom is now building a special ice-resistant platform for the development of the field. The platform will be more than 135 meters long, 69 meters wide, 41 meters tall from the base to the helicopter pad, and its weight will exceed 40,000 tons in total.

The structures placed on the platform will include, inter alia, main and auxiliary drilling modules, operational and energy complexes, and living quarters for 120 people.

The ice-resistant platform will be used to build 33 main directional production wells (later on, another 22 wells for maintaining production rates will be placed on satellite ice-resistant conductor platforms that do not require the permanent presence of personnel). The extracted gas will be fed into pipelines and arrive onshore into a comprehensive gas treatment unit and a booster compressor station. After that, the gas will go into Russia's Unified Gas Supply System.
