SummaryWrap-up
The Course
Structural design and scantling determination are crucial steps in the vessel’s design process. Structural strength must be sufficient to withstand the loads on the boat. Moreover, the structure and its scantling are also linked to other aspects of a vessel, such as resistance or stability.
These calculations can be carried out according to the ISO 12215 norm, an internationally recognized standard for vessels up to 24 meters long. Compliance with ISO 12215 is mandatory for obtaining the CE marking and, therefore, for selling boats in the European Union.
In this course, we will detail the scantling process with the ISO 12215 norm.
To that aim, the course is structured into three parts:
First, the fundamentals of the strength of materials will be introduced. As a prior step to the scantling, we will also discuss the structure definition process.
The second part will present an explanation of the ISO 12215 norm. This includes the structure of the norm and the formulae to be applied in scantling determinations.
Finally, several relevant examples will be carried out in the third part with downloadable calculation templates. These will be developed for the scantling of a sailing yacht built in fiber-reinforced polymer, including the calculation of composites properties, the computation of both monolithic and sandwich panels, and the calculation of stiffeners. Besides, relevant elements such as the rudder, the keel, and the rig will be computed according to their corresponding parts of the norm.
By completing this course, you will be able to:
- Design the structure of a boat.
- Understand the ISO 12215 norm and the fundamentals behind it.
- And apply this norm to evaluate the scantling of either motorboats or sailing yachts.
