20ft DNV-ST-E271 Certified Offshore Equipment Frame
Qingdao Boxwell
The 20ft DNV-ST-E271 Certified Offshore Equipment Frame is designed for the safe lifting, transportation and handling of oversized machinery and skid-mounted equipment used in offshore environments.
This product belongs to Offshore Containers → Offshore Frames and is manufactured in accordance with DNV-ST-E271 for offshore lifting, marine transportation and long-term offshore service.
DNV-ST-E271 provides technical requirements and guidance for the approval and certification of offshore containers and lifting sets, including requirements relating to manufacturing, testing, marking and periodic inspection.
With external dimensions of 6058 × 2438 × 2896 mm, the frame provides a large open platform for integrating industrial equipment while maintaining a defined offshore transport structure.
The open-frame design provides convenient equipment access and can accommodate equipment that would be difficult to install inside a conventional enclosed offshore cargo container.
Suitable equipment includes:
● Generators
● Compressors
● Pumps
● Hydraulic Power Units (HPUs)
● Transformers
● Water treatment systems
● Control panels
● Other large industrial equipment
The frame has a 13,000 kg payload and a 4,000 kg tare weight.
This capacity makes the frame suitable for substantial machinery and equipment packages, subject to the approved equipment layout, center of gravity, load distribution and certification documentation.
The frame incorporates four certified lifting pad eyes for offshore crane handling.
The lifting point arrangement is an integral part of the engineered frame and should be used in accordance with the approved design, certification documentation and lifting procedure.
An appropriate sling set is available as an optional configuration.
Forklift pockets are available, providing an additional handling method for applicable yard, workshop and shore-base operations.
The frame uses SPA-H steel together with reinforced structural members, corner areas and a heavy-duty base structure.
The structural configuration is engineered around offshore lifting and equipment transportation requirements rather than the construction of a conventional ISO dry cargo container.
The frame undergoes Sa2.5 blast cleaning before application of the specified protective coating system:
● Zinc-rich epoxy primer
● Epoxy intermediate coat
● Polyurethane top coat
The marine coating is intended to provide protection against salt spray, humidity and harsh offshore weather conditions.
We support customized equipment frames according to project and equipment requirements.
Available options include:
● Project-specific dimensions
● Lifting slings
● Lashing points
● Equipment mounting brackets
● Removable side rails
● Access platforms
● Customized RAL colors
The final configuration can therefore be developed around the equipment dimensions, weight distribution and center of gravity.
The 20ft Offshore Equipment Frame is intended for offshore and marine projects requiring certified handling of machinery, skid-mounted systems and project equipment.
The frame can be used for appropriate machinery and equipment packages required on offshore oil and gas projects.
Typical equipment can include pumps, compressors, HPUs, generators and other mechanical systems suitable for this product.
Offshore platforms are a primary application environment.
The open frame provides an engineered lifting and transport structure for moving project equipment between shore bases, vessels and offshore facilities.
Drilling rigs are also included in the application range.
Equipment dimensions, payload, mounting arrangement and center of gravity should be reviewed before the final frame design is approved.
Floating Production Storage and Offloading units (FPSOs) are among the intended applications.
Customized mounting and securing arrangements can be developed for the equipment package carried by the frame.
The frame can be used within offshore logistics involving Offshore Supply Vessels (OSVs).
Certified lifting points support the transfer of equipment as part of an approved offshore lifting operation.
Offshore wind farms are also an application for the equipment frame.
Suitable applications can involve mechanical, hydraulic, electrical or other project-support equipment where the frame is engineered for the specific equipment package.
Marine construction projects can use offshore equipment frames for large equipment and skid-mounted systems requiring a dedicated transport and lifting structure.
Offshore-certified equipment solutions are relevant to oil and gas, offshore wind and industrial offshore projects.

Packing List
Every offshore container passes through a complete manufacturing process under strict quality control.
We maintain a dedicated Offshore Containers product range that includes offshore cargo containers, half-height containers, baskets, bottle racks, waste skips, tool boxes, workshops and offshore frames.
This 20ft Offshore Equipment Frame therefore belongs directly to our offshore product line rather than being a modified standard dry cargo 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.
This experience supports project-specific engineering where equipment dimensions, weight, center of gravity and lifting requirements must be incorporated into the frame design.
We support:
● Customer drawing-based production
● Project-specific structural design
● Non-standard offshore containers
● Equipment modules
● Customized offshore frames
● Certification-oriented engineering
Our engineering team can support projects from concept development through final production.
Our products can be designed and manufactured according to internationally recognized standards including:
● DNV 2.7-1 / DNV-ST-E271
● EN 12079
● CSC
● ISO
● Other project-specific requirements
For this particular Offshore Equipment Frame, 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 operates with more than 200 workers.
Our quality-management system covers:
● Raw material inspection
● Production-process monitoring
● Final product testing
We also invest in testing equipment to support product consistency and performance verification.
We cooperate with independent inspection agencies and classification societies where required by the project and certification scope.
Our service scope includes:
● Pre-sales technical consultation
● Engineering design
● Manufacturing
● Production monitoring
● Quality control

It is designed to lift, transport and support oversized machinery and skid-mounted systems used in offshore environments.
Suitable equipment types include generators, compressors, pumps, HPUs, transformers, water treatment systems and control panels.
The dimensions are:
● Length: 6058 mm
● Width: 2438 mm
● Height: 2896 mm
These dimensions should be confirmed against the final approved engineering drawing for the individual project.
The weight specifications are:
● Payload: 13,000 kg
● Tare Weight: 4,000 kg
The final allowable equipment load should comply with the certified frame design and approved weight distribution.
The standard design temperature is -20°C.
Lower design temperatures are available according to project requirements, but a fixed lower limit such as -40°C is not specified.
Yes. The frame has four certified lifting pad eyes.
The lifting arrangement should be used according to the approved certification documentation and lifting procedure.
A sling set is optional.
Where required, the sling configuration should be matched to the approved frame design and lifting arrangement.
Yes. Forklift pockets are available, allowing applicable ground handling in addition to certified offshore crane lifting.
DNV-ST-E271 is the product-specific standard. ISO 10855 is not specified as a product certification.
ISO 10855 is a recognized offshore-container standard series, but it should only be added to this product specification if corresponding project documentation confirms compliance.
For engineering review, it is recommended to provide:
● Equipment drawings
● Overall equipment dimensions
● Equipment weight
● Center of gravity
