俄气开始建设北极海上防冰生产平台

据离岸工程6月26日报道，俄罗斯天然气工业股份公司为开发Kamennomysskoye-Sea油田而建造的防冰海上生产平台周四在位于阿斯塔罕地区的南方造船和修理中心(联合造船公司的一部分)开始建设。

Kamennomysskoye-Sea气田位于喀拉海的Ob湾，那里的气温可以降至零下60摄氏度。该气田的天然气储量巨大，约为5550亿立方米。该公司预计在2025年开始生产，设计产能为每年150亿立方米。

俄气表示，该油田所处的海洋环境特点是低温、强风暴、浅水(5-12米)和厚而密的淡水冰。这一领域的开发将成为世界上第一个在如此极端的冰雪和气候条件下实施的陆架项目

俄气目前正在为该油田的开发建造一个特殊的抗冰平台。平台长135米，宽69米，从基地到直升机坪高41米，总重量将超过4万吨。平台上的结构将包括主要和辅助钻井模块、操作和能源综合设施以及可容纳120人的生活区。

该防冰平台将用于建造33口主定向生产井(随后，将在不需要人员永久驻留的防冰导体平台上再部署22口井，以维持产量)。抽取出来的天然气将通过管道输送到岸上，进入一个综合天然气处理装置和一个增压压气站。之后，天然气将进入俄罗斯统一供气系统。

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.
