Published: 2025-06-26 13:48:54

Shanghai Suoqi Deepwater Operations Underwater Umbilical Cable Product Introduction

Shanghai Suo Qi, focusing on the high-difficulty demands of deep-sea engineering, has developed high-performance underwater umbilical cables using cutting-edge technology, providing integrated solutions for deepwater oil and gas development, marine scientific observation, and other operations, integrating power transmission, signal transmission, and fluid control. With outstanding pressure resistance, corrosion resistance, and stable transmission performance, the products break through technical barriers in deep-sea operations and support the national marine strategy.

1. Deep adaptation for diverse deep-sea scenarios

Deepwater Oil and Gas Field Development: In kilometer-deep offshore oil and gas extraction, underwater production systems need to be connected to offshore platforms through umbilical cables. Shanghai Sohke umbilical cables integrate power, hydraulic, chemical injection channels, and communication lines, providing stable power to underwater equipment such as Christmas trees and pumps, transmitting production data in real time, and ensuring efficient oil and gas extraction and remote monitoring.

Marine Renewable Energy Engineering: In deep-sea wind power and tidal current power generation projects, umbilical cables are responsible for connecting subsea cables with surface platforms. Their fatigue-resistant design can withstand seawater fluctuations and current impacts, ensuring stable power transmission to the onshore grid, while also supporting high-speed return of equipment status monitoring signals, enhancing the operational efficiency of the energy system.

Marine scientific research and monitoring: Umbilical cables used for deep-sea exploration robots and seabed observation networks have multi-channel data transmission capabilities, allowing synchronous transmission of data such as geological exploration, hydrological monitoring, and biological research. The product's low latency and high fidelity characteristics help research teams obtain real-time deep-sea dynamic information, providing reliable support for marine scientific research.

Undersea Tunnels and Cross-Sea Projects: In the construction of undersea tunnels and the foundation construction of cross-sea bridges, umbilical cables provide power and control signals to underwater construction equipment (such as tunnel boring machines and pile drivers). Their high-strength structure can withstand mechanical forces during construction, ensuring the stable operation of engineering equipment under complex undersea terrains.

2. Core Technical Advantages and Performance

Super high pressure resistance and fatigue resistance: Using a multi-layer armored structure, the outer layer is wrapped with high yield strength steel wire or composite fiber materials, capable of withstanding deep-sea pressures above 60MPa; the interior uses a spiral stranded design with a flexible cushioning layer, passing millions of bending fatigue tests without damage, suitable for long-term underwater dynamic operations.

Multi-medium integrated transmission: Integrates power cable cores, signal cable cores, hydraulic pipes, chemical agent delivery pipes, and other composite structures to achieve synchronous transmission of electrical energy, data, hydraulic oil, and chemical reagents, reducing external pipeline arrangements for equipment and enhancing system integration and reliability.

Stable communication and low attenuation: Built-in optical fiber or high-performance shielded cable, supporting gigabit-level data transmission, using double-layer shielding and impedance matching technology, with a signal attenuation rate of less than 0.5 dB/km, ensuring real-time communication between deep-sea and surface platforms without delay or interference.

All-environment protection capability: The outer sheath is made of special polyether polyurethane material resistant to seawater corrosion, with an added antimicrobial coating, capable of withstanding harsh environments such as deep-sea high pressure, low temperature, salt spray, and hydrogen sulfide; the fire-resistant design complies with international maritime safety standards, ensuring operational safety under extreme conditions.

3. Innovative Structural Design

Composite cable core system:

Power cable core: High-purity oxygen-free copper conductor paired with cross-linked polyethylene insulation, supporting medium and high voltage power transmission, with a current-carrying capacity of up to 120% of similar products;

Signal cable core: single-mode/multi-mode optical fiber or coaxial cable, supporting dual-channel transmission of optical signals and electrical signals;

Fluid pipeline: Uses high-pressure and corrosion-resistant thermoplastic composite pipes, suitable for the transportation of hydraulic oil, chemical agents, and other media.

Armor and cushioning layer: Double-layer steel wire armor provides mechanical protection, with an aramid fiber cushioning layer in between to balance tensile and torsional performance, capable of withstanding axial forces of over 10 tons.

Sealing and protective structure: Uses metal welded sealing joints and waterproof gel filling to ensure waterproof sealing throughout the entire lifecycle; The outer sheath is enhanced with wear-resistant particles to reduce seabed friction losses.

Shanghai Suoqi strictly follows international standards such as IEC and API, and conducts 1000 performance tests to achieve full-process digital control from raw material traceability to finished product delivery.
