Attached pipe cable system based on jacket platform and design method

Abstract

The invention discloses an attached pipe cable system based on a jacket platform, which comprises a dynamic submarine cable connected with a power system on a jacket and a plurality of pipe clamps for fixing the dynamic submarine cable and the jacket, and the pipe clamps comprise first fixing parts and second fixing parts, a mounting hole used for being fixed to a jacket is formed between the first fixing part and the second fixing part, the first fixing part and the second fixing part are connected through a connecting piece, and a through hole allowing a dynamic submarine cable to penetrate through is formed in the second fixing part. According to the attached type pipe cable system based on the jacket platform and the design method, dynamic submarine cables are successfully applied to the fixed jacket platform, high-risk and high-cost operation such as saturated diving and underwater welding does not need to be carried out on newly-added cables of the jacket platform, and a large amount of cost is saved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an attached umbilical system and a design method based on a jacket platform. Background technique [0002] The jacket platform, also known as the pile platform, is supported by piles driven into the seabed. It can withstand external forces such as wind, waves, and currents. It has the advantages of strong adaptability, safety, reliability, simple structure, and low cost. With the rapid development of offshore oil development, jacket-type offshore platforms are widely used in offshore oilfield development, offshore sightseeing, and marine scientific observation. The normal operation of the jacket platform is inseparable from the use of relevant underwater cables. Under the influence of tides and bad weather, the underwater cables will move, especially in areas with strong wind, waves and currents on the sea surface. Waves and currents will have a greater impact on the underwater c...

Problems solved by technology

The normal operation of the jacket platform is inseparable from the use of relevant underwater cables. Under the influence of tides and bad weather, the underwater cables will move, especially in areas with strong wind, waves and currents on the sea surface. Waves and currents will have a great impact on the underwater cable, and it is easy to cause damage to the underwater cable for a long time, which will have a certain degree of impact on the service life of the underwater cable, and then affect the normal operation of the jacket platform

Based on this, it is necessary to protect the underwater cable to resist the impact of the ocean's wind, waves, and currents on the underwater cable. At present, it is common to install a J-shaped protective tube on the underwater cable to protect the underwater cable. However, the manufacturing cost of the J-shaped protective pipe is high, and the installation and construction are also relatively complicated, which leads to high construction and use costs of the entire jacket platform
