DNV-ST-E271 Certified Offshore Gas Cylinder Bottle Rack
Qingdao Boxwell
The DNV-ST-E271 Certified Offshore Gas Cylinder Bottle Rack is designed for the lifting, transportation and storage of compressed gas cylinders in offshore and marine environments.
Suitable applications include oxygen, nitrogen, argon, acetylene, carbon dioxide and other industrial gas cylinders.
Unlike a general-purpose cargo container, the rack uses a dedicated open-frame structure with cylinder-retaining components to help control cylinder movement during offshore handling.
The product is manufactured in accordance with DNV-ST-E271.
DNV-ST-E271 provides technical requirements and guidance for the approval and certification of offshore containers and associated lifting sets, including requirements relating to manufacturing, testing, marking and periodic inspection.
The structural material is SPA-H steel.
The bottle rack incorporates:
● Reinforced steel framing
● Certified lifting pad eyes
● Forklift pockets
● Cylinder-retaining bars or chains
● Individual cylinder-securing devices
● Protective structural elements
These features are intended to support controlled handling of compressed gas cylinders during offshore logistics.
The rack uses heavy-duty cylinder retaining bars or chains together with individual cylinder-securing devices.
The purpose of these components is to limit unwanted cylinder movement and contact during handling and transportation.
The exact securing arrangement should be selected according to the cylinder dimensions, quantity and approved rack configuration.
The rack uses an open-frame design, providing direct visibility and access to the cylinders.
The open structure is beneficial for:
● Loading
● Unloading
● Visual inspection
● Ventilation
The open design should not, however, be treated as a substitute for project-specific gas-cylinder storage, segregation or hazardous-area procedures.
The rack includes four certified lifting pad eyes for offshore crane handling.
The lifting arrangement should be used according to the approved certification documentation and lifting procedure.
A compatible sling set is available as an optional configuration.
Forklift pockets are available for appropriate ground-level handling at yards, shore bases and other locations where forklift operations are permitted.
The protective treatment includes:
● Sa2.5 blast cleaning
● Zinc-rich epoxy primer
● Epoxy intermediate coat
● Polyurethane top coat
The bottle rack is intended for offshore conditions involving salt spray, humidity and demanding daily operations.
No specific coating DFT should be stated unless confirmed by the approved project specification.
Customization covers:
● Cylinder capacity
● Overall dimensions
● Color
● Cylinder securing systems
● Identification plates
● Optional protective covers
This allows the rack configuration to be developed around the actual cylinder sizes, quantities and operating requirements.
The Offshore Gas Cylinder Bottle Rack is intended for offshore and marine logistics where compressed gas cylinders require a dedicated lifting, storage and transport structure.
The rack can be used to transport and store suitable industrial gas cylinders required for offshore maintenance, fabrication and operational work.
The rack is suitable for offshore platform applications.
Drilling rigs are another application.
The rack provides a dedicated framework for organizing and handling compressed gas cylinders used in appropriate drilling, maintenance and repair operations.
Floating Production Storage and Offloading units (FPSOs) are among the intended environments.
Customized cylinder-retaining arrangements can be selected according to the gas cylinders required for the project.
The bottle rack can also be incorporated into offshore logistics involving Offshore Supply Vessels (OSVs).
The certified lifting arrangement supports applicable transfer operations between vessels, shore bases and offshore facilities.
Offshore wind projects are included in the application range.
The rack can be configured for appropriate industrial gas cylinders used during fabrication, installation, maintenance or repair activities.
Shipyards and marine service operations are additional applications.
The open structure allows direct access and visual inspection while keeping cylinders restrained within a dedicated transport rack.
The product is suitable for offshore maintenance operations where oxygen, nitrogen and other industrial gases need to be organized and moved as part of the project logistics chain.
Offshore transport containers are purpose-designed for movement between ships and fixed or floating offshore facilities and are subject to higher structural, welding and inspection requirements than ordinary freight containers.

Packing List
Every offshore container passes through a complete manufacturing process under strict quality control.
We maintain Offshore Bottle Rack as a dedicated category within our Offshore Containers range, alongside offshore cargo containers, baskets, waste skips, tool boxes, workshops and equipment frames.
This product is therefore designed specifically for offshore cylinder handling rather than adapted from a standard shipping container.
Our core engineering and R&D team has more than 20 years of industry experience in offshore containers, special containers and customized equipment solutions.
The experience figure refers to our professional engineering and manufacturing team rather than the age of our company itself.
We support:
● Customer drawing-based production
● Technical specification-based manufacturing
● Non-standard offshore product development
● Project-specific structural design
● Customized cylinder capacities and dimensions
● Customized securing systems
This capability is particularly relevant to bottle racks because cylinder sizes and quantities can vary between projects.
Our products can be designed and manufactured according to internationally recognized standards including DNV 2.7-1 / DNV-ST-E271, EN 12079, CSC, ISO and project-specific requirements.
For this particular Bottle Rack, the product-specific standard is DNV-ST-E271.
We were founded in May 2020 in Jiaozhou, Qingdao.
Our factory covers approximately 60,000 m², including 32,000 m² of workshop space, and has more than 200 workers.
Our quality-management system covers:

The specifications are:
● External Dimensions: 1100 × 1100 × 2160 mm
● Payload: 2,000 kg
● Tare Weight: 600 kg
Final loading should comply with the approved rack configuration and certification documentation.
No fixed cylinder quantity is specified.
Bottle racks can be customized with different cylinder capacities and dimensions.
The final capacity should therefore be determined from the actual cylinder diameter, height, weight and approved securing arrangement rather than assuming a generic 12- or 16-cylinder configuration.
The rack can incorporate:
● Heavy-duty retaining bars
● Chains
● Individual cylinder-securing devices
● Protective structural components
The final securing method should correspond to the cylinder configuration approved for the project.
The open structure provides easier:
● Loading
● Unloading
● Inspection
● Ventilation
However, the rack itself should not be presented as replacing site-specific compressed-gas handling and safety procedures.
The configuration includes:
● Four certified lifting pad eyes
● Forklift pockets
● Optional sling set
The offshore lifting arrangement should follow the approved DNV-ST-E271 documentation and project lifting procedure.
The standard design temperature is -20°C.
Lower design temperatures are available according to project requirements, but a fixed lower limit is not specified.
No.
CSC Plate: N/A.
This product is an offshore gas-cylinder rack rather than a conventional CSC-approved ISO freight container.
For an accurate engineering review, it is recommended to provide:
● Gas cylinder type
● Cylinder quantity
● Cylinder diameter
● Cylinder height
● Individual cylinder weight
● Total required payload
● Preferred rack dimensions
● Securing-system requirements
● Protective-cover requirement
● Required design temperature
● Sling-set requirement
● Required certification
● RAL color
● Identification / marking requirements
● Quantity
● Delivery destination
We can then develop the bottle-rack configuration around the actual cylinder dimensions, quantity and project requirements using our customer drawing-based and non-standard offshore engineering capability.
