To solve the unique refrigeration demands of offshore voyage -heavy continuous load, high fresh-keeping standards and non-stop r operation, and comply with core process standards for tuna, including quick-freezing temperature recovery for fresh locking and low-temperature stock storage, CB provided refrigeration system for this vessel, consisting of:
* 4 sets of screw compressor units (2 two-stage units + 2 single-stage units),
* 12 sets of floor-standing air coolers, and other auxiliary equipment.
* A specialized floor grating system to optimize air circulation loop inside hold, delivering consistent, uniform temperatures throughout the cargo hold, and fully satisfying the vessel’s quick-freezing and cold storage operational requirements.

This dual-purpose refrigeration system for both quick-freezing and cold storage effectively resolves core long-standing pain points of conventional marine refrigeration systems, eliminating key industry issues such as insufficient rapid cooling & fresh-locking capacity for bulk pelagic tuna catches, high energy consumption during equipment operation, and inconsistent fresh preservation results.

After commissioning, the system significantly cuts energy consumption for quick-freezing, cold storage and transport per unit catch. The complete solution aligns with the low-carbon, eco-friendly, high-efficiency and energy-saving development trend of pelagic fisheries. It substantially improves the stability and efficiency of the vessel’s cold chain operations, enables enterprises to achieve upgrading of fishery cold chains, and builds core competitive advantages in pelagic fishing, cold storage and cargo transportation.
