Understanding DNV 2.7-1 Certified Offshore Containers

Introduction:
DNV (Det Norske Veritas) plays a crucial role in ensuring safety at sea and on land through its certification and verification services. In this article, we'll explore the key characteristics and benefits of DNV 2.7-1 certified offshore containers, highlighting their importance in harsh offshore conditions.

DNV 2.7-1 Certification: What Sets Them Apart
DNV 2.7-1 certified offshore containers are purpose-built for dynamic hoisting, equipped with eye pad devices and DNV certified slings with shackles. These containers undergo rigorous checks throughout their lifecycle, including the design phase, material procurement, production, and final loading, as well as Non-Destructive Examination (NDE) testing.

Testing and Quality Assurance
Unlike standard containers, DNV 2.7-1 containers are subject to meticulous testing procedures. Prototypes are rigorously tested, and a specific number of units from each batch are randomly selected for testing, ensuring a level of scrutiny five times higher than ISO standard containers.

Robust Construction
One of the distinguishing features of DNV 2.7-1 containers is their solid steel structure, which includes reinforced floors. These containers are designed to withstand the challenges of rough seas, making them substantially heavier compared to ISO containers of the same size. This added weight is essential to keep them upright during transportation in adverse conditions.

DNV Approved Slings and Materials
DNV 2.7-1 containers are equipped with DNV-approved slings and incorporate stronger steel. The production process adheres to strict specifications to ensure the highest quality. All test documentation is readily available to demonstrate their reliability in offshore environments.

Certification Process
Classification societies play a vital role in certifying offshore containers. The process involves:

1. Design Evaluation: This includes a thorough examination of container materials, cargo handling capabilities, lifting mechanisms, and cargo securing methods.
2. Manufacturing Process: Certified inspectors scrutinize raw materials and confirm that welder qualifications, welding processes, and non-destructive testing meet stringent requirements.
3. Testing: DNV 2.7-1 containers undergo a battery of tests, including four-point lifts, two-point lifts, tilt tests, and drop tests.

 
Conclusion:
​DNV 2.7-1 certified offshore containers are engineered to meet the demanding needs of offshore industries. Their robust construction, rigorous testing, and adherence to DNV standards ensure their reliability in the harshest offshore conditions, making them a vital asset for maritime safety and efficiency.
