Wijma Marine Consultants provide stability verification calculations according to the harmonized standards of ISO 12217. The recreational craft directive (CE) requires the producer to show compliance with the stability requirements by calculations or tests.
How we work:
Together with the client we will discuss what kind of calculations or tests are applicable to their products.
- When tests are required we will make an overview of these tests including their requirements. With this overview the producer can prepare themselves for an inspection of the notified body (when needed).
- When calculations are required we will provide a list of needed information (e.g. main dimensions, weight calculations/measurements including centre of gravities, tank plan, sail plan, etc.).
For the stability calculations we have the following software inhouse:
- Delftship software
We have the possibilities to model hulls from lines plans or to import digital models from designers.
We will report the results of the calculations in such a way that the notified body can perform an efficient inspection. Most of the time we submit the technical documentation for assessment and no comments or additional calculations are required by the inspection bureaus.
It is our aim to support the yacht building industry in an efficient way by keeping quality in mind.
