What are offshore cargo carry units (CCUs)?
Offshore cargo carry units are certified containers and frames designed for transporting equipment and materials to offshore platforms and vessels. Built to DNV 2.7-1 / 3 standards, they ensure safe lifting, secure handling, and reliable cargo transport in harsh marine environments.
What types of offshore cargo carry units are available?
Common types include offshore containers, subsea baskets, offshore skids, and specialized frames. Each type is designed for specific cargo, such as tools, bulk materials, or heavy equipment, ensuring safe and efficient offshore logistics.
What standards do offshore CCUs comply with?
Most offshore cargo carry units are manufactured in accordance with DNV 2.7-1 / 3 standards, CSC approval(for option), painting testing and prototype testing. These certifications ensure structural integrity, lifting safety, and compliance with offshore oil and gas industry requirements.
Can offshore cargo carry units be customized?
Yes, CCUs can be customized in size, payload capacity, lifting points, and structural design. Additional features such as forklift pockets, pad eyes, and internal securing systems can be added based on specific offshore applications.
How are offshore cargo carry units used in real operations?
Offshore cargo carry units are widely used to move tools, spare parts, and bulk materials between supply vessels and offshore installations. They are designed for repeated lifting cycles, ensuring stable handling during crane operations and minimizing cargo damage in rough sea conditions.
How do you choose the right type of CCU for your project?
Selecting the right CCU depends on cargo type, weight distribution, and handling method. Closed containers are ideal for protected transport, while open frames or baskets are better suited for oversized or irregular equipment requiring easy loading and unloading.
What makes offshore CCUs different from standard containers?
Unlike standard shipping containers, offshore CCUs are engineered for dynamic lifting rather than static stacking. Reinforced structures, certified lifting points, and impact resistance allow them to perform safely under offshore crane operations and harsh weather exposure.
What factors affect the lifespan of offshore cargo units?
Service life depends on usage frequency, environmental exposure, and maintenance practices. Regular inspection, proper coating systems, and structural checks are essential to ensure long-term performance in corrosive offshore conditions.
