The brief introduction of DNV2.7-1 Offshore Type Cargo Basket

The DNV2.7-1 Offshore Type Cargo Basket is a specialized container system designed for safe and efficient transportation of goods, equipment, and materials in offshore oil, gas, wind energy, and marine environments. Certified to the DNVGL-ST-E271 standard (formerly DNV 2.7-1) , these baskets are engineered to withstand the dynamic forces and harsh conditions encountered during offshore operations, including heavy seas, extreme temperatures, and rigorous lifting procedures.

Key Features and Design Specifications

• Structural Integrity
  Constructed with high-strength steel and corrosion-resistant coatings (e.g., hot-dip galvanization or specialized paint) , Cargo Baskets feature a robust framework capable of handling payloads ranging from 1,500 kg to 16,500 kg across various models. Their solid steel floors and reinforced corners ensure stability during lifting and stacking. Unlike standard ISO containers, DNV2.7-1 baskets are twice as heavy, providing superior resistance to tipping and structural failure in rough seas .
• Safety Enhancements
  • Internal Lashing Points: Secures cargo (e.g., gas cylinders, pipes, tools) using integrated straps and chains, minimizing movement during transport .
  • Certified Slings and Shackles: DNV-approved slings with shackles are included for safe lifting, complying with EN 12079 and ISO 10855 standards .
  • Forklift Pockets and Twist Locks: Facilitate onshore and offshore maneuvering, while twist locks enable stacking of multiple baskets (e.g., two 10 ft baskets can form a single ISO-compliant unit) .
  • Drainage and Ventilation: Prevents water accumulation and ensures air circulation, critical for preserving sensitive cargo .
• Modular Dimensions
  Available in sizes from 10 ft to 76 ft , these baskets accommodate diverse cargo types. For example:
  • Half-Height Baskets: Ideal for small, heavy items like anchors and chains .
  • Full-Height Baskets: Designed for bulkier equipment or gas cylinders (e.g., 16-bottle configurations with guide frames) .

Certification and Testing

The DNV2.7-1 certification process involves rigorous testing to validate performance under extreme conditions:

• Dynamic Load Tests: Four-point and two-point lifting tests simulate real-world scenarios .
• Drop and Impact Testing: Ensures the basket retains structural integrity after accidental drops or collisions .
• Material and Welding Inspections: Verifies compliance with DNV’s strict standards for material quality and welding procedures .
• Periodic Inspections: Mandatory after 5 years (or earlier if damage is suspected) to maintain certification dnv.com.

DNV’s digital tools, such as the Offshore Container Certification Application, streamline the approval process by providing real-time design feedback and reducing turnaround time by up to 50% dnv.com.

Applications

Cargo Baskets are indispensable in offshore logistics for:

• Transporting Specialized Cargo: Gas cylinders (argon, acetylene, oxygen) for welding and diving , drill pipes, anchors, and offshore tools .
• Wind Energy Projects: Efficiently moving turbine components and maintenance equipment between onshore facilities and offshore wind farms .
• Emergency Response: Rapid deployment of safety gear and disaster relief supplies to remote platforms .

Their stackable design and compatibility with ISO container systems optimize space on supply vessels and rig decks, reducing logistical costs .

Compliance and Global Recognition

DNV2.7-1 certification is internationally recognized, ensuring seamless cross-border transportation and compliance with regulatory bodies worldwide . The standard aligns with EN 12079 (offshore containers) and MSC/Circ. 860 (safety recommendations for lifting appliances) , making these baskets a preferred choice for operators adhering to strict maritime and offshore regulations.

Advantages Over Conventional Containers

• Safety-Centric Design: Minimizes risks associated with cargo shifting, corrosion, and structural fatigue.
• Efficiency: Reduces downtime through quick loading/unloading and compatibility with existing offshore infrastructure.
• Cost-Effectiveness: Long lifespan and resistance to damage lower maintenance and replacement costs .
• Versatility: Adaptable to diverse cargo types and operational environments, from Arctic conditions (-40°C) to tropical regions .

Market Availability

Suppliers offer both sale and rental options, with short- and long-term leases catering to project-specific needs . Customization (e.g., color, logo, or specialized compartments) is often available to meet unique client requirements .

Conclusion

The DNV2.7-1 Offshore Type Cargo Basket is a cornerstone of offshore logistics, combining rugged durability with advanced safety features to ensure reliable transportation of critical assets. By adhering to DNV’s stringent standards, these baskets not only safeguard personnel and equipment but also streamline operations in one of the world’s most challenging industries. Whether transporting gas cylinders to a drilling rig or tools to a wind farm, the Cargo Basket exemplifies the fusion of engineering excellence and practicality required for offshore success.
