Offshore Drilling Platform Cable Solutions

Project Background:

An internationally renowned oil exploration company has constructed a new offshore drilling platform in the North Sea region. Due to the harsh marine conditions in the North Sea, the performance requirements for cables are extremely high. The platform needs to operate stably under extreme maritime environments, placing stringent demands on the corrosion resistance, heat resistance, and vibration resistance of the cables.

Shenxing Solutions:

For this project, Shenxing Cables provided customized cable solutions to meet the special requirements of the drilling platform operating in harsh marine environments.

Corrosion-resistant, Seawater-resistant, Fatigue-resistant Cables:

• Material Selection: 

• Using cross-linked polyethylene (XLPE) insulation layer with excellent heat resistance, chemical resistance, and effective resistance against seawater corrosion. The outer jacket is made of specialized weather-resistant TPE material with excellent wear resistance, oil resistance, ozone resistance, effectively resisting erosion from UV light and salt spray.

• Structural Design: The cable interior adopts a multi-strand stranded structure, enhancing the flexibility and tensile strength of the cable. The outer layer uses a high-strength steel wire braiding layer, effectively improving the tensile strength and vibration resistance of the cable.

Heat-resistant, Humidity-resistant, Oil-resistant Cables:

• Material Selection: Using heat-resistant XLPE insulation and oil-resistant outer jacket, capable of long-term stable operation on drilling platforms with severe temperature, humidity, and oil contamination.

• Structural Design: Adopting flat conductor design, increasing the contact area between the conductor and insulation layer, reducing resistance, and improving thermal conductivity.

Electromagnetic Compatibility (EMC) Cables:

• Shielding Design: Using multi-layer shielding structure, effectively suppressing external electromagnetic interference to ensure normal operation of equipment.

• Filter Design: Installing filters at the cable joints, further reducing electromagnetic interference.

Performance Indicators:

• Corrosion Resistance: Passed 2000-hour salt spray corrosion test, no significant damage to the outer jacket, complying with IEC 60092 standards.

• Heat Resistance: Operating temperature range: -50°C to 150°C, significantly higher than ordinary cables.

• Vibration Resistance: Passed 100,000 bending cycles, stable cable performance without breakage.

• Electromagnetic Compatibility: Complying with IEC 61000-4-6 standard, possessing good electromagnetic compatibility.

Application Effects:

• Enhanced Operational Efficiency: Stable power supply increased the operational efficiency of the drilling platform by 20%, reducing operational costs.

• Extended Equipment Lifespan: Corrosion-resistant, fatigue-resistant cables maintained good condition in harsh marine environments, extending cable lifespan and reducing maintenance costs.

• Guaranteed Operational Safety: Reliable cable performance ensured the normal operation of the power system on the drilling platform, preventing shutdowns due to cable failures.

Customer Evaluation:

A project manager from an offshore oil exploration company commented, "Shenxing cables have performed exceptionally well on the drilling platform. They not only withstand harsh working environments but also significantly enhance the platform's operational efficiency. We are very satisfied with the quality and service of Shenxing cables."

Summary:

Shenxing Cables provided reliable power transmission solutions for offshore drilling platforms, effectively addressing cable application challenges in harsh marine environments. Through advanced materials and designs, Shenxing Cables demonstrated outstanding performance in terms of corrosion resistance, heat resistance, and vibration resistance, creating significant economic benefits for customers.
