Every answer and its explanation appears here once you have finished the path. Each one then links to the matching glossary entry, where the concept is set out in full with its worked example.
1. What lies behind an untested technology exclusion?
The admission that it is not known what is being insured: a technology with no history has no price
Believing in a lack of appetite leads to negotiating a price, and there is no price to negotiate: with no history, the insurer can neither rate nor bound, and the exclusion says that rather than a reluctance. The practical consequence is that the lever is documentary rather than commercial, and that is the subject of the next question as of the module on rating without history. The answers invoking regulation or reinsurance move the constraint onto someone else, which reassures and changes nothing: the direct insurer would be no better able to rate if nobody imposed it.
Glossary entry · sinistralite-attritionnelle2. A machine of a proven model is installed in a version scaled up by a third. What does the untested technology clause do?
It does not settle it: industrial innovation proceeds by changes of scale, the clause opens the debate and the contractual definition closes it
The two categorical answers share the same flaw, believing the clause contains its own answer: it opens a question only its contractual definition closes, and it is that definition to read and negotiate before ordering. The point to retain is that a change of scale IS the ordinary mode of industrial innovation, so a strictly read clause would exclude almost every large project, and a loosely read one would exclude nothing. The number of units already delivered, proposed by another answer, is a frequent criterion in these definitions and never the only one.
Glossary entry · energie-offshore3. One and the same design defect appears on several units of a series of sixty. What decides the amount?
The aggregation clause: one loss or sixty, and the defect is present in every unit from the factory
The technical fact exists from the moment the units leave the factory, so the question is not how many units are affected but how many times the deductible and the limit apply: between one loss and sixty, the gap is one deductible against sixty, and sometimes a limit reached against a limit intact. The answer counting failures describes what is seen on the ground and not what the contract computes. The date of first failure matters for the policy year, which is a real and separate question.
Glossary entry · sinistralite-attritionnelle4. The defect appears on the twelfth unit of a series being deployed. What follows?
That the whole fleet already carries it: the series deploys faster than experience accumulates
The order of revelation says nothing about the order of manufacture: a design defect is in every unit, and those that have not yet failed are the ones that ran least or were luckiest. It is that mismatch between the pace of deployment and the pace of experience that makes such series dangerous, and it is visible in the schedule rather than in an expert report. The answer declaring the first eleven sound is the one immediate observation produces, and it is exactly contrary to the technical fact.
Glossary entry · energie-offshore5. Expert evidence establishes that the forty-eight sound units will fail. Is their preventive replacement a loss?
No, whatever the technical certainty: it is the manufacturer's warranty, and the negotiation is run on the supply contract
A property policy presupposes damage, and a working unit carries none: the certainty that it will one day fail describes a non-conformity, not a loss, and it is the supplier that answers for it. It is the same reasoning as the non-compliant but intact anchorages, and it holds under any wording. Invoking emergency measures, as another answer suggests, is the subtlest attempt: they serve to limit imminent damage and not to replace sound property to avoid future damage.
