The P15 project aims to contribute towards greater precision in the structural analysis of fish farm facilities by focusing on more precisely defined load models and analytical methods. In the long-term, this has the potential to reduce the risk of structural damage and fish escapes, and help boost personnel safety.

In recent years, there has been a focus on increasing the quality of input to strength calculations linked to fish farm installations, including designed environmental loads and netting dimensions. More precise design values also require a corresponding increase in precision linked to load models. For this reason, it is the right time to establish more precise load models.

Fish farm nets are a natural area of research focus because they account for the greatest load contribution in the form of drag forces generated by currents and wave action. The formulae used to calculate the drag forces on netting were developed about 30 years ago, and there is now a need to modify these to adapt to current and future netting materials, as well as new and precise methods for solidity measurement. Towing experiments will be carried out during 2019 that will form the basis for the development of new load models.

The aim in 2019 is to develop improved load models for conventional netting materials, implement the models in software, and carry out comparisons with existing models. Emphasis will be focused on a thorough documentation of solidity using a variety of methods.

Innovation potential:

  • Safe and optimal fish farm technology
  • Software development
