Abstract

The invention relates to a submarine cable for a power grid interlink of offshore oil platforms, which is characterized in that a plurality of offshore platform power stations on a plurality of offshore oil drilling platforms distributed in a sea area are connected through submarine cables so as to form a small-sized grid-connected power system. The submarine cables are compound type submarine cables, which are provided with submarine optical cable units and optical fibers with the voltage class of 35KV and the cross section of 3*(150-250)mm<2>. The submarine cables have excellent electric, physical and chemical properties, are beneficial to enhancing the communication capability of the grid interlink among all oil fields, and can effectively guarantee the effectiveness of optical fiber communication, greatly enhance the anti-torque capability of the optical fibers and ensure the smooth communication of the power grid interlink.

Description

【Technical field】

[0001] The invention relates to a submarine cable, in particular to a submarine cable for connecting multiple offshore platform power stations arranged on multiple offshore oil platforms. 【Background technique】

[0002] At present, all countries in the world are constantly strengthening the development and utilization of marine resources, especially the development and utilization of offshore oil and natural gas resources. Power supply is an important link in oil and gas development. Because most of the offshore oil and gas fields are far away from each other, in terms of mining methods, most of them at home and abroad currently use a central platform to build a power station to supply power for the central platform and each wellhead platform. This power supply method has problems such as insufficient power supply reliability, repeated resource allocation, insufficient resource utilization, high operating and maintenance costs, and large energy consumption...
