Selecting a certification body is one of the early decisions on any offshore container project, and it is often treated as a formality. It should not be. The certification body affects your design approval timeline, your fabrication hold point schedule, and the quality of the review your engineering package receives. The choice matters more than most procurement teams realise at the point of decision.
Who DNV and Lloyd’s Register Are — Briefly
Both DNV and Lloyd’s Register (LR) are independent classification and certification bodies with global coverage in the offshore sector. Both are recognised by major operators and flag state administrations for DNV 2.7-1 and EN 12079 offshore container certification. Neither is universally mandated by a single international regulation — the choice is typically driven by the operator’s or client’s approved vendor list, the jurisdiction, or practical considerations around survey availability.
The two organisations are competitors, but the practical differences between them for a given offshore container certification project are smaller than their marketing would suggest. What matters for your project is not the brand but the specific office, the specific surveyor pool, and the relationship your engineering firm has built with them.
Practical Differences That Affect Your Offshore Container Project
The most concrete practical difference is surveyor geography. DNV has strong surveyor coverage in the North Sea, the Middle East, and Southeast Asia through a network of owned offices. Lloyd’s Register has comparable coverage but the distribution varies by region — in some fabrication locations one body has significantly better surveyor availability than the other. If your manufacturer is in a location where the offshore container certification body has limited presence, hold point scheduling becomes harder and more expensive.
Design review turnaround time is the second most consequential practical difference — and it is variable. Both bodies have published indicative timelines, but actual turnaround depends on current workload, the complexity of the DNV 2.7-1 submission, and the quality of the engineering firm’s submission package. A well-prepared submission to a busy certifier often clears faster than a poorly prepared submission to an available one. The certifier matters; the engineering firm submitting to them matters more.
Familiarity with specific standards varies by local office. Both DNV and LR staff are trained to certify to DNV 2.7-1 and EN 12079, but an offshore container certification office that sees a high volume of projects will have a more refined understanding of what a complete submission looks like. This is a legitimate factor in selection, particularly for bespoke or complex units.
If your manufacturer already holds an approval certificate from one of the two bodies, that is a meaningful practical advantage. The manufacturer’s quality management system is already within the certifier’s audit scope, and the surveyor relationship is established.
When the Operator or Client Decides for You
The freedom to choose an offshore container certification body is often illusory. Major operators typically maintain approved certifier lists, and the EPC contract will frequently specify which bodies are acceptable. Equinor, BP, Shell, and TotalEnergies each have established relationships with specific certification bodies, and deviating from those relationships requires a formal derogation that most projects do not have time for.
Before engaging a certification body, check the approved vendor list for the project. If the client has specified one or more approved certifiers, the relevant question is which of the approved bodies is best placed for your specific project location and timeline.
Capacity constraints occasionally create a situation where the specified body has a queue. Some projects have navigated this by engaging the preferred body for design approval while identifying a second body to cover production surveying — effectively splitting the offshore container certification scope. This requires careful management and agreement from the client, but it is sometimes the only way to protect the schedule.
What to Ask Before Committing
Does the operator’s approved vendor list specify a preferred offshore container certification body? If so, your choice is made.
Where will fabrication take place, and does the body have surveyors in that location with availability? Ask the certification body directly for their current surveyor coverage in the fabrication region.
What is the current design review turnaround time for DNV 2.7-1 offshore container submissions of this complexity? A direct question gets a direct answer. If the answer does not align with your project schedule, that is information you need early.
Has your engineering firm worked with this body before on comparable equipment? The relationship between the offshore container engineering firm and the certification body matters. A firm that knows what the certifier’s reviewers expect will produce a better-structured submission package and will handle the review process more efficiently.
