If you’ve typed “DNV 2.7-1 vs 2.7-2 vs 2.7-3” into a search bar, you’re not alone. These three standards are routinely confused — even by experienced procurement teams. This guide explains each one plainly, shows how they differ, and gives you a concrete decision tree to identify which standard governs …
Most offshore container manufacturers are still producing their DNV 2.7-1 certification calculations in Excel. The spreadsheet might be well-built — with formulas locked, units clearly labeled, and a senior engineer reviewing the printout before submission. But it still arrives at the surveyor’s desk as a spreadsheet PDF, often with cross-sheet …
The August 2017 edition of DNVGL-ST-E271 replaced the previous DNV 2.7-1 standard, consolidating the offshore container requirements into a single DNV GL standard document and introducing a number of changes that designers and manufacturers need to be aware of. This post explains what changed, what stayed the same, and what …
When a manufacturer sets out to certify an offshore container, the question surfaces almost immediately: do I certify against DNV 2.7-1 or EN 12079? The short answer is that for most practical purposes, you are certifying against the same technical requirements. But the longer answer involves different standards bodies, slightly …
Offshore containers do not last forever — or rather, their certification does not. Every offshore container that operates in regulated environments needs periodic recertification to confirm that the structure remains fit for purpose, the lifting sets are within their service life, and the corrosion protection is still effective. This post …
Choosing the wrong material for an offshore container — or the right material with the wrong properties — is one of the most common reasons certification fails at first review. The problem is rarely a fundamental misstep; it is usually a missing check, an undocumented assumption, or a detail that …
Every offshore container that moves on an offshore installation or vessel must survive three distinct mechanical environments — each one governed by a specific load case in DNVGL-ST-E271. Get any one of them wrong and the certification fails, or worse: the container fails in service. This post walks through all …
Most engineering training programmes are described in terms of topics covered. This one is better described in terms of what you produce — because the work is the learning. Over 10 weeks, participants in our Engineering Foundation Programme complete weekly exercises, marked quizzes, and a capstone project that replicates a …
You can read DNV-RP-C203. You can work through EN ISO 15614-1. You can open BS 4-1:2020 and find the section modulus table. The standards exist to be used without a training course. Nobody is going to test whether you attended a lecture before they accept your calculation. So the question …
A structural detail is subjected to a stress range of 100 MPa at N = 10⁶ cycles. Is this acceptable? The answer most engineers give — if they have some familiarity with fatigue design — is to check whether 100 MPa is below the allowable stress for the applicable FAT …
There is a gap between what a mechanical or civil engineering degree teaches about structural mechanics and what offshore structural engineering practice actually requires. It is not a gap in intelligence or effort. It is a gap in specific, code-anchored knowledge that nobody bothered to write down in a usable …
In 1980, the mobile offshore drilling unit Alexander L. Kielland capsized in the North Sea during a storm. One hundred and twenty-three people died. The formal investigation concluded that a fatigue crack in a brace end — a crack that had propagated from a weld toe over an estimated 10,000 …
