20ft Offshore Container For Sale | DNV Certified

20ft Offshore Container For Sale — DNV Certified for Marine & Offshore Cargo

This 20ft offshore container is built to a different standard than a general-purpose dry container — it’s certified for crane lifting onto offshore platforms, supply vessels, and marine installations, where dynamic loads from wave motion and lifting operations demand a higher engineering standard than standard ISO freight containers are rated for. Designated ISO type code 22G0, this unit carries a dual weight rating: one figure for offshore/crane-lift use, and a separate (higher) figure for standard dry-van ground transport.

Key Features

• DNV 2.7-1 / EN 12079 certification for offshore crane lifting
• High-visibility yellow corner castings for improved visibility during lifting operations
• Reinforced lifting points rated for dynamic offshore loads, not just static ISO lifting
• “Tag Line Only” designated attachment points for load control during crane operations
• Dual weight rating: offshore-rated MGW and separate standard dry-van MGW
• Double cargo doors with locking cam bars and gasket seal

Why Offshore Containers Are Rated Differently

A standard shipping container is engineered for static stacking loads and highway/rail transport — it’s never expected to be lifted by crane with cargo swinging above open water. An offshore container is a different engineering category entirely: it’s tested and certified against DNV 2.7-1 (or the equivalent EN 12079 standard), which accounts for dynamic amplification factors from wave-induced motion, wind loading, and the snatch loads that occur during lifts onto moving vessels or platforms. That’s why this unit carries a lower Maximum Gross Weight rating for offshore use than its dry-van rating — the offshore figure reflects what’s safe under those dynamic conditions, not just static weight capacity.

Who Uses a 20ft Offshore Container

• Oil & gas operators moving equipment and supplies to offshore platforms
• Offshore wind farm construction and maintenance logistics
• Marine and port operations requiring vessel-to-vessel or vessel-to-dock crane transfers
• Subsea equipment and tooling storage/transport
• Any operation requiring DNV-certified cargo handling documentation for compliance

Certification You Can Verify

DNV 2.7-1 is issued and maintained by DNV, the leading classification and certification body for maritime and offshore industries. Every container carrying this rating should have a valid, verifiable DNV certificate — ask our team for the certification documentation for this specific unit before ordering, since offshore compliance requirements typically require this on file for platform access.

Delivery

This unit ships via standard tilt-bed delivery for ground transport to your yard or staging area. Note that offshore/marine deployment (crane lift onto vessel or platform) is handled by your marine logistics provider at the point of use — we deliver to your specified ground location. Contact us for a delivery quote and to confirm current DNV certification status.

Frequently Asked Questions

What’s the difference between DNV 2.7-1 and standard ISO container certification?

ISO 668/1496 governs standard container dimensions and static/stacking strength for general freight. DNV 2.7-1 is a separate, stricter certification specifically for offshore crane lifting, accounting for dynamic loads from wave motion and vessel movement that standard ISO containers are never tested against.

Can this container also be used for standard ground storage or freight?

Yes — the dual rating means it’s certified for both offshore crane-lift use and standard dry-van ground transport, giving you flexibility if your needs change.

Do I need to see the DNV certificate before purchasing?

Yes, strongly recommended. Offshore operations typically require valid, current DNV certification documentation for platform/vessel access — request the certificate for this specific unit from our team before ordering.
