2. 2 | Wind and Water Power Programeere.energy.gov Purpose, Objectives, & Integration Anchoring and mooring systems are a substantial and disproportionate share of the installed cost of MHK systems. Future MHK Energy Systems will tend to be most favorably located in dynamic and high energy marine environments that coincide with the presence of severe seafloor conditions where traditional anchoring systems are impractical : –harder outcrops of sediments –rocky reefs –steep slopes –rocky bottoms such as lava flows or areas of high currents –narrow installation window A solution addressing these MHK anchoring challenges is needed at an affordable and competitive cost

3. 3 | Wind and Water Power Programeere.energy.gov Relationship to MHK Program Mission and Objectives MHK program objective is to support and enable installation of cost-effective MHK systems Advanced Anchoring Technology task enables MHK technologies by expanding candidate site options and by reducing anchoring/mooring costs as a portion of overall system cost

4. 4 | Wind and Water Power Programeere.energy.gov Technical Approach Leverage off development of terrestrial grouted anchor and deep water offshore technologies Critical factors in this development: –Drilling –Grout chemistry –Placement of grout This approach builds on proven terrestrial technology to replace “brute force” (bigger and heavier anchors) offshore Conceptual Design of Grouted Anchor System
