FAQ

1. What are marine seismic survey cables used for?

Marine seismic survey cables are used in offshore geophysical exploration systems to connect seismic sensors, survey equipment and surface support systems for power delivery, signal transmission and data communication. They are designed for reliable underwater operation where seawater resistance, flexibility, mechanical strength and stable transmission performance are critical.

2. What is a seismic umbilical cable?

A seismic umbilical cable is an integrated cable assembly designed to provide power, control and communication connections between marine seismic equipment and surface support systems. Seismic umbilical cables can combine multiple functions, including power conductors, signal cores and fiber optic channels, within a reinforced cable structure for complex offshore survey operations.

3. What is a gun umbilical cable used for in marine seismic systems?

Gun umbilical cables connect marine survey vessels with underwater air gun systems used for seismic data acquisition. They provide essential functions such as power supply, triggering, control and synchronization, ensuring reliable operation of seismic source equipment during offshore surveys.

4. Can seismic cables integrate power, signal and fiber optic channels?

Yes. Customized seismic survey cable systems can integrate power conductors, control cores, signal transmission elements and fiber optic components within a single cable structure. This integrated design enables power supply, equipment control and high-speed data communication through one cable solution, reducing system complexity and improving connection reliability.

5. How are marine seismic cables designed for continuous towing operations?

Marine seismic cables are designed to withstand repeated bending, dynamic mechanical stress and long-term movement during towing operations.

Key design considerations include:

- Flexible cable materials and construction

- Mechanical reinforcement for tensile and bending loads

- Water-resistant protection for offshore environments

- Stable performance during repeated deployment and recovery cycles

Cable structures can be customized according to towing speed, deployment depth and operational requirements.

6. Can subsea cables be customized for marine survey systems?

Yes. Custom subsea cable solutions can be developed according to marine survey requirements, including conductor configuration, shielding design, mechanical reinforcement, waterproof protection and integrated functional structures. Customized cable designs help match specific equipment interfaces, installation methods and offshore operating conditions.
