As part of the Department of Energy ARPA-E MARINER program, an experimental test farm has been deployed over the past four years in Kodiak, Alaska with the goal of increasing yield per unit area and increasing operational efficiencies. During that time, we have worked to improve all aspects of the farming process, with our fair share of successes and learning experiences. The farm utilizes a TendOcean™ catenary system that provides the structure required for dense farming while optimizing production and enabling operational efficiencies unachievable with traditional farming practices. The system has gone through several iterations since its inception to increase size, yield, and operational efficiency with the addition of longer grow-lines, buoyancy techniques, connections, and tensioning mechanisms.  The process and techniques used to fabricate and deploy these complex farm systems has been iterated and refined; now entire catenary systems can be shipped to the farm site and deployed as a single unit. The operational efficiencies provided by the catenary system required rethinking traditional methods of seeding, monitoring, and harvesting. We describe some of the advancements we have made in component design and testing to mechanize seeding and harvest and improve material handling and product quality. We are confident that the efficiencies developed from this project can reduce the cost of production, which will allow the industry to supply new markets.
