The seastead design features a 40 feet by 16-foot living area supported by four columns extending 20 feet into the water at a 45-degree angle. The columns are 4 feet wide, and their bottom ends are connected by a rectangular float system measuring 44 feet wide by 68 feet long. The structure is designed to withstand approximately 30,000 lbs of weight and is intended to operate using solar power, submersible mixers, and propellers for low-speed movement.
Your proposed idea of using a rope or chain to pass under the leg/float and anchor below the end of the leg is feasible but requires careful engineering.>. Below are key considerations for this approach:
Duplex Stainless Steel:
Geotextile Fabrics: Consider using geotextile fabrics around the anchor systems to protect the seabed from scouring and improve anchor stability.
Environmental Impact: Evaluate the environmental impact of the materials and anchors to ensure compliance with local regulations and to minimize harm to marine ecosystems.
Your proposed anchoring system is viable, but it requires thorough engineering analysis to ensure safety and durability. Using duplex stainless steel for the columns, chain, and anchors is an excellent choice to avoid galvanic corrosion. For further details, consult with a marine engineer specializing in anchor systems and structural design.
