Presentation 1: Developments on Offshore Fish Pen Designs and Mooring Systems
Presented by Mr Sean van Steel (CoreMarine AS, Oslo)
As Aquaculture systems move into higher energy environments, they experience higher environmental loads for a more sustained period of their life. This exposure drives a need for larger structures and/or a more frequent maintenance plan to be implemented. Our experience to date is with larger O+G style installations such as HavFarm1. Sean will cover the challenges in designing and installing these styles of structures. He will also cover some of the more practical lessons learnt over the past years from their work with these systems
Presentation 2: Challenges related to analysis and design of fish farms for exposed waters
Presented by Prof Jorgen Amdahl (Norwegian University of Science and Technology (NTNU), Trondheim)
As the fish farming industry moves into more exposed waters the installations must be designed on the basis of first principles. The experience obtained from offshore oil & gas installations constitutes a useful background in this context and design methods that have been developed may be used to a large extent also for aquaculture systems. However, significant differences may exist, notably w.r.t environmental conditions, loads and load effects assessment. Various differences will be examined, and challenges related to notably FLS and ULS assessment will be discussed.
