Aquaculture operations in exposed localities will place new demands on vessels and equipment in terms of safe operations, efficient operability and profitability. The interactions between installations and support vessels will be a key factor during operations.

The project has been studying new vessel design concepts and the interface with aquaculture installations with the aim of enhancing operational reliability in exposed localities. It is anticipated that the use of larger vessels will demand new requirements for the design of floating collars and mooring systems. Assuming that current net pen technologies will be adapted for use in exposed localities, the interaction between flexible collars and vessel hulls will be an important factor. A focus on real operational settings will be key to risk mitigation and increased levels of safety, operability and profitability.

The project will start with a study aimed at identifying the challenges we face in exposed localities in relation to vessels, installations, crews and the fish. There will also be separate work packages linked to vessel design (new designs and systems), operations in exposed localities (application of new technology and new procedures), and feasibility studies.

The project will combine expertise from several fields of research linked to the SFI EXPOSED project.

Results:

  • An approach to feasibility studies
  • Fish carrier simulation
  • Feed barge analysis tools
  • Coupled analysis of net pen-fish carrier interaction
  • Design follow-up
  • Vessel data for the service catamaran
  • Operational limits

Innovation potential:

  • Fish carrier simulations will not only provide additional knowledge on the optimum size, composition and capacity of the vessel fleet, but also effective assessments of new vessel concepts. The opportunity to simulate how a given logistical solution will perform over a period (such as one year).
  • Increased understanding of vessel-installation interactions will contribute towards the development of vessels, equipment and methodologies used in exposed localities.
  • Increased understanding of vessel response and operational limits will enable the adaptation of vessel designs and equipment to operational conditions, and thus increase operational efficiency. Increased understanding will also enable safer operations within a greater range of weather conditions.
