This dataset provides technical information from the drop test campaign conducted at Sandia National Laboratories' 300-foot Drop Tower Facility from 9/16/24 - 9/20/24, where full-scale prototypes of Sperra's patented ultra-low-cost concrete torpedo anchors were evaluated for embedment performance in saturated sandy seabed conditions. The data supports the validation of concrete torpedo anchors as a cost-effective, low-carbon alternative to steel torpedo anchors for use with anchoring marine energy, with results informing future numerical modeling improvements and design refinements.\n\nThis project is part of the TEAMER RFTS 9 (request for technical support) program.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://mhkdr.openei.org/files/723/Sperra%20TEAMER%20Torpedo%20Drop%20Test%20Post%20Access%20Report%20Version%201%20%28redacted%29%20-%20Rev03.pdf", "description": "The TEAMER post access report for this RFTS 9 project.
