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 …
Building the Next Generation of Offshore Engineers: Introducing the Offshore & Mechanical Engineering Foundation Programme The offshore and marine sectors continue to face a challenge that many organisations recognise but few have successfully addressed. While graduate engineers often arrive with strong academic foundations, there remains a significant gap between university …
Structural Design Training for Offshore Container Engineers An introductory article for engineering teams new to—or returning to—offshore container certification. The Problem Everyone Recognises and Nobody Talks About You have a container to certify. You know DNV 2.7-1 exists. You know EN 12079 is relevant. You have a spreadsheet that someone’s …

You have a certified offshore container. You need to modify it. Before you cut, weld, or reconfigure anything, understand what that does to your DNV 2.7-1 certification — and what it will take to get it back. This is where offshore container projects run into trouble. Not because the engineering …
Buyers who have not commissioned an offshore container engineering package before often ask what they are actually paying for. The deliverables look like a folder of drawings and calculations — which, at the simplest level, they are. But the value is not in the documents themselves. It is in what …
The engineering fee for an offshore container is a small figure against the total project cost. That is precisely why it receives insufficient scrutiny — and precisely why problems that originate in the engineering phase end up costing multiples of the original fee by the time the container reaches the …
Lifting analysis for offshore containers is one of those areas where the gap between theoretical understanding and what actually gets specified in practice is wider than it should be. The terminology is familiar — dynamic amplification factor, sling angle, pad eye design — but the way these parameters interact in …
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. …
