BLOG – Selkie Tool Development Workshops: Foundation & Mooring Workshop

As part of the Selkie project, Gavin & Doherty Geosolutions (GDG) and partners are producing new open-source tools to assist with the design of foundations, anchors, and mooring systems for marine energy projects. Station-keeping systems are crucial to success in marine energy: in pilot projects, these systems have represented a large proportion of the capital expenditure, but array developments will require efficient and reliable systems to be produced at much lower cost. Building on the findings of similar research projects, such as DTOcean and DTOceanPlus, GDG and partners will produce new decision-support tools to facilitate concept design, cost estimation, and option studies for station-keeping systems. These tools will be designed to be quick and easy to use, and to complement those produced by the DTOcean and DTOceanPlus projects. A key strength of the new tools will be their connection with Selkie’s web-based GIS/techno-economics tool, which is being developed by partners at UCC.

An interactive workshop was held specifically to gather feedback from key actors with a vested interest in Foundations & Moorings  on 23rd November 2021.  Attendees included representatives from Barret Marine Energy Consulting, Blackfish Engineering, DP Energy, DTOcean, DTOceanPlus, Marine Power Sytems, Morek, Orbital Marine Power and Tadek.

This workshop  provided experienced stakeholders with detailed descriptions of three new Selkie design tools, covering the design of gravity-based foundations and anchors, suction caisson foundations and anchors, and catenary and taut mooring systems, ahead of their release in Spring 2022. The workshop format, alternated between short presentations and breakout discussions, and aimed to gather feedback on the proposed form and functionality of the new tools. The Selkie team were  keen to identify both areas for improvement and useful test cases with which to validate the tools.

Discussion and input was gathered through x-leap relating to:

  • type and form of module
  • design methodology
  • system selection criteria
  • estimation of capital costs
  • useful test cases

Overall, the workshop reached its desired outcome – to assist in validating the current planned functionality of the tool.  The team were  pleased with the level of feedback and engagement which will be factored in the next steps of the  development, in making an open-source tool with the aim of benefitting the sector.
