What are subsea cargo baskets?
Subsea cargo baskets are heavy-duty structures designed for lifting, transporting, storing, and deploying equipment and materials in offshore and underwater operations. They are commonly used to support subsea installation, maintenance, and inspection activities in harsh marine environments.
These baskets are engineered to withstand offshore handling conditions and are suitable for use with cranes, winches, and ROV-supported operations.
What materials are used for subsea cargo baskets?
Sinortek subsea cargo baskets are fabricated from Q345B steel to provide high strength and durability under offshore operating conditions.
Material selection is focused on load-bearing capability, long-term reliability, and resistance to mechanical stress during lifting and deployment.
What coating systems are applied to subsea cargo baskets?
To protect against corrosion in marine environments, subsea cargo baskets are commonly finished with a hot-dip galvanizing (HDG) and painting coating system.
This combination provides enhanced corrosion resistance and helps extend the service life of the basket during offshore and subsea operations.
What size options are available for subsea cargo baskets?
There are three sizes with three load capacities to choose from: 10ft,13ft, and 20ft. Custom basket sizes are supported. The current product version has been upgraded.
What are the features of the new type of subsea cargo baskets?
The new subsea basket enables quick and convenient connection of shackles and tie-down straps, while enhancing overall structural strength and stability to improve work efficiency.
What testing and certification are provided for the subsea baskets?
From fabrication to completion, every basket is strictly monitored and documented at each stage of production to ensure consistent quality control throughout the entire process. During manufacturing, comprehensive inspections and tests, including Loading Test, Magnetic Particle Testing (MT), and Ultrasonic Testing (UT), are carried out in accordance with applicable standards to verify structural integrity and weld quality, ensuring reliable performance in real operating conditions. （Details on the production process and testing）
Conclusion
Subsea cargo baskets are essential tools for offshore and underwater operations, providing a reliable solution for transporting and handling equipment in demanding marine environments. Designed to DNV standards and manufactured with durable materials and protective coatings, they offer dependable performance for a wide range of subsea applications.
