When it comes to offshore containers used in the oil and gas industry, DNV2.7-1 is a widely recognized standard. However, selecting the right paint standard for these containers can be challenging. Two options to consider are C3 and C5 standards.

The C3 standard is suitable for containers used in general marine environments, with coatings having medium durability and anti-corrosion properties. The minimum paint thickness should be 75μm. On the other hand, the C5 standard is suitable for containers used in highly corrosive environments, with coatings having high durability and anti-corrosion properties. The minimum paint thickness should be 150μm.

It's important to consider the specific usage environment and requirements when selecting the paint standard for DNV2.7-1 compliant containers. For general marine environments, the C3 standard is typically sufficient. However, if the container will be exposed to highly corrosive environments, the C5 standard should be used.

Proper surface preparation, primer application, intermediate coats, and topcoat thickness are also crucial factors in ensuring the longevity and durability of the paint on DNV2.7-1 compliant containers.

In conclusion, choosing the right paint standard is essential to ensure the safety and longevity of DNV2.7-1 compliant containers. By understanding the differences between C3 and C5 standards and considering the specific usage environment, you can make an informed decision and select the appropriate standard for your container.

As defined by the International Maritime Organization, an offshore container is a "portable unit specially designed for repeated use in the transport of goods or equipment between fixed and/or floating offshore installations and ships. Known in the offshore oil and gas community as "slippery rails "as they are often used to transport large assemblies to drilling and production rigs.
DNV's certification standards 2.7-1, 2 and 3 are a globally recognized set of certification standards for offshore containers and marine service modules. ​The certification standards relate to the certification of all types of marine containers as transport units. The three typical stages of transportation are: shore-based residency (eg, forklifts), supply vessels, and loading and unloading offshore facilities. The certification standards include design requirements related to all three phases.
There are five basic steps for DNV approval and certification:
1. Certification of our (or our client's designation) written welding procedures, laboratory tests and welder qualifications
2. Evaluate and approve our primary device/skid/frame designs
3. Audit/Survey during initial welding start-up
4. Production：Audits/investigations during equipment manufacturing
5. Prototype testing：For "type" approval (type approval means a series of identical units are manufactured over a period)

What is DNV certification?
DNV (Det Norske Veritas), a Norwegian classification society, merged with Germanischer Lloyd (GL) in September 2013 to form the world's largest classification society DNV GL Group.
 As a classification society, DNV GL sets standards for the offshore, maritime, energy and oil and gas industries. The purpose of these standards is to provide users, operators and engineers with requirements, principles and acceptance criteria.

Two common standards are:

• DNVGL-ST-E271, Offshore containers (2.7-1)
• DNVGL-ST-E273, Portable offshore containers (2.7-3)

 
DNV2.7-1 and DNV2.7-3 in common

• Both 2.7-1 and 2.7-3 are standards specify requirements and recommended practice covering transport of offshore containers and portable offshore containers.
• The standards cover the specific areas of design, manufacturing, testing, certification, and periodic inspection
• Both standards cover the lifting frames or containers and, in most cases, not the equipment contained within the frames
• Both standards cover the safe lifting and handling of offshore containers and installations between two floating vessels and between vessels and fixed or floating offshore installations.

 
Difference between DNV2.7-1 and DNV2.7-3
Apart from the difference in standard details, the biggest difference is that the maximum gross weight (MGW) of dnV2.7-1 certified container is less than 25,000 kgs, and the MGW of DNV2.7-3 certified container is greater than 25,000 kgs.
 
Although DNV2.7-1 and DNV2.7-3 standards are set by DNV Classification Society, they are also recognized by other classification societies (BV, LRs, etc), which will issue corresponding certificates according to the same standards.

ABS guildline for portable offshore accommodation modules

The installation of modular buildings for use as living quarters, industrial spaces, and workshops has become increasingly prevalent in recent years. Irrespective of the amount of time that portable modules are installed onboard, the potential risks to personnel within these buildings can be comparable to those within a traditional living quarters structure.
Due to the transient nature of portable accommodation modules, it is possible that the buildings may be installed on a number of different types of vessels and offshore units over their life. In recognizing that the ABS class requirements differ based on the type of host vessel or facility, this Guide has been created to outline the process for the design and survey of the modules and to establish the requirements for modules which can be used on any category of offshore drilling unit, production facility, barge, steel vessel, or high speed craft.

Class Approval Process
The ABS approval process for accommodation modules is a four-step process as outlined below:
• Design Review of the Module 
• Survey of the Module at Fabrication Facility
• Design Review for Installation Approval 
• Survey onboard Host Vessel 

The ABS review process of the module commences with drawings and documentation detailing the module’s general arrangements, structural fire protection, electrical configuration, structural design, and machinery and piping systems being submitted to the ABS technical office for review. Upon completion of the review, drawings will be returned to the submitter and forwarded to the attending ABS Surveyor. Receipt of the drawings by the ABS Surveyor permits the physical survey of the module at the fabrication facility to be commenced.
Once a host vessel for the module is determined, design review for installation approval can be commenced. Upon receipt of the documentation detailing the module and the proposed location onboard the host vessel, the ABS technical office can review the arrangements. Once the ABS engineers have determined that the proposed location onboard the host vessel is suitable for the subject module, stamped drawings will be returned to the submitter and made available to the attending ABS Survey office. Upon receipt of these drawings, the attending ABS Surveyor may attend the vessel and confirm that the installation of the modules is in accordance with the approved arrangements.
The manufacturer is to assign a unique serial number to identify all modules being reviewed to this Guide. The initial submission of drawings is to specifically indicate the serial number of modules to be built in accordance with the drawings.
