DNV 2.7-1 and DNV 2.7-2 are two of the most common and most
trusted certifications in the offshore world. DNV issues them
(Det Norske Veritas), an independent global quality assurance and risk
management company.

DNV has created a series of standards, and
these two are the most important for offshore containers and equipment.
In this chapter, we’re going to break down what DNV certification is,
what’s included in the certificates (DNV 2.7-1 and DNV 2.7-2), and what
you might expect in terms of costs.

What is DNV?

DNV is a leading certification and classification body that provides
services to industries ranging from oil and gas to renewable energy,
automotive, and maritime sectors. They are focused on risk management
to ensure that products, services, and operations meet international
standards for safety, environmental protection, and quality.

DNV’s certification services are based on rigorous assessments and
testing to verify that products and systems meet specific criteria. For
companies involved in offshore operations, adhering to DNV standards
demonstrates a commitment to safety, reliability, and performance.

What is DNV 2.7-1 Certification?

DNV 2.7-1 is a standard specifically created for offshore containers.
These are the containers that are used to transport goods and equipment
in a marine environment. Offshore containers are subject to some
extreme conditions including high winds, saltwater corrosion, and rough
handling. DNV 2.7-1 ensures that these containers are built to withstand
these challenges.

Key Elements of DNV 2.7-1:

1. Design and Construction: The containers must meet stringent
requirements regarding structural integrity and design.
2. Material Testing: The materials used for construction must pass
specific tests to ensure they can endure tough environmental
conditions.
3. Lifting Requirements: Offshore containers need to be able to be
lifted by cranes and other equipment in rough seas.
4. Safety Markings: There are specific markings required to ensure
proper identification and safe handling.
A container that holds a DNV 2.7-1 certificate assures users that it
complies with international safety and quality standards for offshore use.

What is DNV 2.7-2 Certification?

DNV 2.7-2 is an extension of DNV 2.7-1, but it’s more focused on
portable offshore units rather than simple containers. These units might
include things like accommodation modules, control rooms, or workshop
containers used in offshore oil rigs or similar environments.
DNV 2.7-2 involves stricter testing and additional checks to ensure
that the units not only meet design and safety standards, but they’re also
capable of accommodating people or providing a controlled environment
under harsh conditions.

Key Elements of DNV 2.7-2:

1. Fire and Explosion Protection: Since these units are more complex,
the standard ensures the units are designed to protect against fire,
explosions, and toxic gases.
2. Structural Integrity: The units must be constructed in a way that
withstands both operational loads and environmental forces.
3. Comfort and Usability: If the unit is used for accommodation or
control purposes, DNV 2.7-2 ensures that it is safe and comfortable
for personnel inside.
Units certified to DNV 2.7-2 are designed for higher risk environments
to ensure that both personnel and equipment are protected.

Certificate Contents

A DNV certificate, whether for DNV 2.7-1 or DNV 2.7-2, typically
contains:
1. Certificate Number: A unique identification number for tracking
and validation.
2. Certification Body Information: Details about DNV as the issuing
authority.
3. Company and Product Information: Information about the
company applying for the certification and the specific product
(e.g., container or offshore unit).
4. Compliance Details: A summary of the specific standards met such
as material specifications, lifting capacities, and safety features.
5. Inspection and Test Records: Details of the tests and inspections
carried out by DNV during the certification process including
material testing and structural assessments.
6. Validity Period: The dates during which the certification is valid
and any conditions for re-certification.
7. Additional Conditions or Notes: Any extra information regarding
special conditions or requirements tied to the certified product.

Cost of DNV Certification

The cost of obtaining DNV certification varies depending on several
factors:
1. Type of Product: Certifying a standard offshore container to DNV
2.7-1 might cost less than certifying a complex offshore unit to DNV
2.7-2 due to the different levels of testing and inspection required.
2. Complexity of the Inspection: More detailed inspections such as
those for offshore living modules or hazardous environments will
require more resources, pushing up the costs.
3. Size of the Company: Large companies with extensive infrastructure
might need a more comprehensive certification process, potentially
increasing the cost.
4. Additional Testing Requirements: If a product or unit doesn’t
initially meet the standards and requires additional testing or
redesign, this can add to the cost.
In general, the cost for DNV certification can range from $5,000 to
$20,000 or more depending on the complexity and scale of the product
being certified. Keep in mind that there may also be ongoing costs for
periodic re-certification or maintenance of the certification status.

Conclusion

DNV certifications, specifically DNV 2.7-1 and DNV 2.7-2, are
essential for ensuring the safety and integrity of offshore containers and
portable offshore units. They guarantee that these products meet
international standards and can perform safely in challenging marine
environments. The certification process is rigorous, and the cost reflects
the level of detailed testing and inspection required, but the benefits of
compliance—namely safety, reliability, and global trust—make it a
valuable investment for any business involved in offshore activities.
