20ft DNV-ST-E271 Certified Offshore Equipment Frame
Qingdao Boxwell
The DNV-ST-E271 Certified Offshore Equipment Frame is designed for the lifting, transportation and protection of machinery, skid-mounted systems and other project-specific equipment used in offshore environments.
The frame is manufactured in accordance with DNV-ST-E271 and is intended for offshore lifting, marine transportation and long-term offshore service.
DNV-ST-E271 provides technical requirements for the approval and certification of offshore containers and lifting sets, including requirements relating to manufacturing, testing, marking and periodic inspection.
The open-frame configuration provides flexible access for installing and transporting equipment that may not fit efficiently inside a fully enclosed offshore container.
Suitable applications include:
● Generators
● Compressors
● Pumps
● Hydraulic Power Units (HPUs)
● Transformers
● Water treatment systems
● Control panels
● Other large industrial equipment
The final frame geometry can be developed around the dimensions and configuration of the actual equipment.
The frame includes four certified lifting pad eyes for offshore lifting operations.
The lifting arrangement forms part of the engineered offshore frame and should be used according to the approved design, certification documentation and lifting instructions.
Optional lifting slings are also available for this model.
Forklift pockets are incorporated into the frame to support applicable ground handling and logistics operations.
This provides an additional handling method when crane lifting is not required.
The product uses SPA-H steel with a reinforced base structure and structural members designed around offshore transportation and lifting requirements.
The frame also incorporates reinforced corner posts and a heavy-duty base structure to support safe equipment handling.
The steel structure undergoes Sa2.5 blast cleaning before application of the specified coating system:
● Zinc-rich epoxy primer
● Epoxy intermediate coat
● Polyurethane top coat
This coating system provides protection against salt spray, humidity and harsh offshore weather conditions.
The offshore equipment frame can be engineered according to:
● Equipment dimensions
● Equipment weight
● Weight distribution
● Center of gravity
● Required mounting arrangement
● Customer specifications
Optional configurations include lifting slings, lashing points, equipment mounting brackets, removable side rails, access platforms and project-specific dimensions.
The Offshore Equipment Frame is intended for offshore projects where machinery or skid-mounted equipment requires a dedicated certified structure for transportation and lifting.
The frame can be used for transporting and handling project equipment used on offshore oil and gas installations.
Typical equipment can include pumps, compressors, HPUs, generators and other machinery where the frame is engineered around the actual equipment dimensions and center of gravity.
Offshore platforms and drilling rigs are application environments for this product.
The certified lifting arrangement supports transfer of equipment within offshore logistics operations, subject to the approved lifting procedure.
The product is also intended for equipment transportation associated with Floating Production Storage and Offloading units (FPSOs).
Customized securing and mounting arrangements can be incorporated according to the equipment being transported.
Offshore Supply Vessels (OSVs) are among the intended applications.
The frame can provide a dedicated structure for moving project equipment between shore bases, vessels and offshore facilities.
Offshore wind farms are another application.
The frame can be configured for appropriate electrical, hydraulic, mechanical or project-support equipment used within renewable-energy projects.
Marine construction projects can use customized equipment frames for machinery, skids and project-specific components that require controlled lifting and transportation.
Industrial projects are also an application area.
Where offshore certification is required, the frame can be designed around the specific equipment load and handling requirements rather than using a conventional ISO shipping container.

Packing List
Every offshore container passes through a complete manufacturing process under strict quality control.
We maintain dedicated offshore product categories including:
● Offshore Cargo Containers
● Offshore Half Height Containers
● Offshore Mini Containers
● Offshore Baskets
● Offshore Bottle Racks
● Offshore Waste Skips
● Offshore Tool Boxes
● Offshore Workshops
● Offshore Frames
This product therefore belongs directly to our offshore manufacturing range rather than being adapted from a standard ISO 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.
Our company was founded in May 2020, so the 20+ years figure refers specifically to the experience of our core professional team.
We support engineering based on:
● Customer drawings
● Technical specifications
● Equipment dimensions
● Project operating conditions
● Certification requirements
● Non-standard structural requirements
This capability is particularly relevant to offshore equipment frames because equipment dimensions, weight distribution and center of gravity vary between projects.
Our products can be designed and manufactured according to standards including:
● DNV 2.7-1 / DNV-ST-E271
● EN 12079
● CSC
● ISO
● Other project-specific requirements
For this specific product, DNV-ST-E271 is the applicable standard.
We operate a factory covering approximately 60,000 m², including 32,000 m² of workshop space, with more than 200 workers.
Our quality-management process covers:
● Raw material inspection
● Production-process monitoring
● Final product testing
We also use dedicated testing equipment to support product reliability and consistency.
We cooperate with independent inspection agencies and classification societies to support project-specific inspection and certification requirements.
Our services include:
● Technical consultation
● Engineering design
● Manufacturing
● Production monitoring
● Quality control
● Testing
● Certification support
● Third-party inspection coordination
● Logistics and shipment coordination
● After-sales technical support
It is an engineered steel frame used to secure, lift and transport machinery or skid-mounted equipment in offshore logistics operations.
We design this product according to DNV-ST-E271 for offshore lifting and marine transportation.
Suitable equipment includes:
● Generators
● Compressors
● Pumps
● HPUs
● Transformers
● Water treatment systems
● Control panels
● Other industrial equipment
The final frame should be engineered according to the actual equipment dimensions, weight and center of gravity.
The specifications are:
● External dimensions: 3480 × 1870 × 2150 mm
● Payload: 3450 kg
● Tare weight: 1050 kg
However, the model is described as a “20ft” Offshore Equipment Frame, which conflicts with the 3480 mm external length.
The final dimensions should therefore be confirmed from the approved drawing and certification documentation before ordering.
The standard design temperature is -20°C, with lower design temperatures available according to project requirements.
The required design temperature should be confirmed during engineering because it affects the applicable material and certification requirements.
Yes. The frame includes four certified lifting pad eyes.
A sling set is optional and should be selected according to the approved lifting arrangement.
