Problems solved by technology

The traditional composite submarine cable usually has a stainless steel sleeve with optical fiber inside. The stainless steel sleeve is fixed in the triangular area between the cable and the outer steel wire armor by soft fillers. During the cable formation process of the submarine cable, it is easy to lose the soft material during transportation and construction. The filler and the stainless steel loose tube of the optical fiber are squeezed into the cable and damage the optical fiber, which will have a certain impact on the subsequent construction of the power system

Embodiment Construction

[0018] The following examples are further explanations and illustrations of the present invention, and do not constitute any limitation to the present invention.

[0019] refer to figure 1 , The offshore oil platform power networking system of the present invention includes a plurality of offshore oil drilling platforms 10 , a plurality of offshore platform power stations 20 and a plurality of submarine cables 30 . Wherein, the plurality of offshore oil drilling platforms 10 are oil drilling platforms distributed at different locations in an offshore sea area. The distance between multiple offshore platform power stations 20 is 10Km-60Km. The plurality of offshore platform power stations 20 are built independent offshore platform power stations that provide power for the offshore oil drilling platform. They can be any known offshore platform power stations. Because the present invention only relates to submarine cables, the The specific structures of the offshore oil drillin...

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...
