Our Dual-Drum Towing Array Winch Supports CNOOC’s Geophysical Exploration Operations
Project Background and Application
In the vast and challenging field of offshore oil, gas, and mineral resource exploration, high-precision and highly reliable equipment is crucial for obtaining critical data. Our company’s custom-built dual-drum towing array winch system for CNOOC’s geophysical exploration vessels is extensively used in marine seismic surveying, geological sampling, and petroleum resource identification. It serves as an indispensable core asset in marine geophysical operations, injecting robust power into ocean resource exploration and truly fulfilling its role as an “engine for ocean discovery.”
Core Equipment: Dual-Drum Towing Array Winch
This system is designed for complex marine environments and high-precision exploration tasks, featuring the following advanced characteristics:
- Towing capacity of up to 15 tons, reliably meeting various operational demands;
- Innovative dual-drum structure equipped with an automatic clutch disengagement function, enhancing operational efficiency and safety;
- Closed-loop control and high-response constant tension technology ensure extreme stability during deployment and towing;
- Integrated built-in traction machine guarantees even cable load distribution, extending equipment service life;
- Designed based on a 20-foot standard container format, balancing structural strength and mobility.
