What a 20ft DNV Offshore Open Top Container Is

A 20ft DNV offshore open top container is a certified offshore cargo carrying unit (CCU) designed around the familiar 20ft intermodal footprint but with an open roof and removable cover system. Instead of a fixed steel roof, the unit has:

• Full‑strength side walls and end frames.

• A clear roof opening for crane loading from above.

• Roof bows and a tarpaulin or hard top system that can be removed for loading and re‑secured for transit.

This configuration is ideal whenever you need to load:

• Oversize components that can’t pass through standard doors.

• Tall machinery, skids, winches, motors, or awkward shapes.

• Bulk bags, pallets, or crates stacked higher than a normal door opening.

Offshore, the open top design allows the platform or vessel crane to drop cargo straight into the container from above, then close it up with roof bows and tarpaulin for safe sea transport. Buy 20ft DNV Offshore Open Top Containers Online DNV 2.7-1 Certified Units

Core Dimensions and Capacity

Although designs vary slightly by manufacturer, most 20ft DNV offshore open top containers share very similar sizes and capacities:

Typical External and Internal Dimensions

• External length: about 6058 mm (20 ft).

• External width: about 2438 mm (8 ft).

• External height: about 2591 mm (8 ft 6 in).

• Internal length: typically around 5836–5898 mm (about 19’2″).

• Internal width: roughly 2218–2352 mm (about 7’3″–7’9″).

• Internal height: roughly 2284–2348 mm (about 7’5″–7’8″).

This yields an internal cubic capacity of roughly 29–30 m³, giving plenty of usable space for tall equipment while maintaining a standardized offshore container footprint. Buy 20ft DNV Offshore Open Top Containers Online DNV 2.7-1 Certified Units

Roof Opening

The key feature of an open top is the roof opening:

• Roof opening length: typically around 5.76 m.

• Roof opening width: roughly 2.23 m.

This large opening allows cranes to lower loads straight into the container without having to thread them through a door, which is a major operational advantage offshore where crane time and sea conditions are critical. Buy 20ft DNV Offshore Open Top Containers Online DNV 2.7-1 Certified Units

Weight and Payload

Typical weight and payload ranges include:

• Tare weight: often around 3,100–3,700 kg depending on design and panel style.

• Offshore max gross weight: commonly in the 13,200–19,700 kg range.

• Offshore payload: typically around 10,000–16,000 kg.

Some designs also list separate ISO/CSC payloads and gross weights for global intermodal use, with ISO payloads reaching above 20 tonnes while offshore payloads are conservatively limited for dynamic lifting safety. Buy 20ft DNV Offshore Open Top Containers Online DNV 2.7-1 Certified Units

DNV 2.7‑1 / EN 12079 / ISO 10855 Certification

A serious buyer looking to buy 20ft DNV offshore open top container for sale must be sure the unit is truly offshore‑certified, not just a standard open‑top box. Key points include:

• Design and build to DNV 2.7‑1, often with cross‑references to EN 12079 or ISO 10855.

• Third‑party certification by recognized classification societies, with a data plate showing:

  • Design standard.

  • Maximum gross weight.

  • Design temperature range.

  • Serial number and manufacturing data.

• Certified lifting set supplied with each container (wire or chain slings and shackles sized for the container’s MGW and rated sling angle).

This certification ensures that the container and its lifting gear can withstand:

• Dynamic loads from sling angles and crane accelerations.

• Impacts and motion at sea.

• Long‑term corrosion and fatigue in offshore service.

Construction: Steel, Coatings, and Weather Protection

Structural Materials

A 20ft DNV offshore open top container is typically constructed from:

• Corten‑type weathering steel (e.g., Corten‑A or equivalent) for improved corrosion resistance.

• Heavy‑section corner posts, front and rear frames designed to carry lifting loads via pad eyes or corner fittings.

• Stiffened sidewalls and end walls to resist deformation when loaded from above and during vessel motion.

The result is a robust frame that can handle heavy loads and repeated crane lifts without structural compromise.

Coatings and Finishes

Because these containers live in marine environments:

• They are coated with multi‑layer marine paint systems, often with significant dry film thickness to resist salt and abrasion.

• Colors are usually high‑visibility to improve safety on vessel decks and platforms.

• Coating systems are chosen to withstand wide temperature ranges (often down to ‑20 °C or even lower) and UV exposure.

Roof Bows and Tarpaulin

The “open top” is not literally open in transit; it is closed using:

• Roof bows – transverse steel members that support the tarpaulin and help maintain structural shape.

• Tarpaulin (soft open top) – heavy‑duty cover that can be removed or rolled back for loading, then secured with lashing bars or cords.

• In some designs, hard‑top lids or removable roof panels are used, but the principle remains the same: easy overhead loading with weather protection during transport. Buy 20ft DNV Offshore Open Top Containers Online DNV 2.7-1 Certified Units

Operational Advantages Offshore

1. Overhead Crane Loading

On a crowded platform or supply vessel, swinging long or tall pieces of equipment through doors is risky and slow. 20ft DNV offshore open top containers allow you to:

• Lower loads straight into the unit from above with precision.

• Avoid clearance issues at door frames.

• Reduce damage risk to cargo and container horns/door frames.

2. Handling Tall and Odd‑Shaped Cargo

Open tops are perfect for:

• Skids, pumps, winches, motors, and machinery that exceed door height.

• Tall stacked pallets or bulk bags.

• Pipe bundles and components that must be craned in and out frequently.

3. Flexible Use with and without Cover

When conditions require:

• You can operate with the top open for quick around‑deck operations.

• You can close up the tarpaulin and roof bows for sea passages to protect cargo from spray, rain, and debris.

Integration with PullCarGoTrailers.com Transport Solutions

Even though these containers are offshore‑rated, they still match the standard 20ft footprint, which means they integrate seamlessly with your road fleet:

• Container chassis: The 20ft length and 8ft width allow direct mounting on 20ft container chassis equipped with twist locks.

• Flatbeds and step‑deck trailers: Half‑height of a container is not required; you can secure the open top just like a standard 20ft box, using twistlocks or container locks where fitted.

• Heavy‑duty goosenecks: For especially heavy loads or combined cargo (open top plus additional equipment on deck), heavy‑duty trailers from PullCarGoTrailers.com can serve both onshore and port‑side roles.

This compatibility lets you:

1. Load tall equipment into open top offshore containers at your inland yard.

2. Move them via road on your PullCarGo‑style chassis and trailers to the port.

3. Transfer them by crane to supply vessels and offshore platforms.

4. Return them onshore and reuse them as rugged, covered storage or for the next offshore campaign.

Common Use Cases and Industries

20ft DNV offshore open top containers see heavy use in:

• Oil and gas – tall tools, long equipment, skid‑mounted systems that cannot fit through standard container doors.

• Offshore wind – tower maintenance equipment, long tooling, cables and rigging.

• Marine construction – grout pumps, generators, complex rigging assemblies, and ROV support systems.

• Special projects – any situation where oversize or tall equipment must travel offshore under controlled conditions.

On land, these same containers function as high‑security storage and staging units, especially useful in coastal yards and industrial sites where weather and security are both concerns. Buy 20ft DNV Offshore Open Top Containers Online DNV 2.7-1 Certified Units
