Screw anchors are designed in a spiral shape, similar to large screws, that can be easily driven into the ground or seafloor using specialized equipment. It can be applied in a variety of soil types, like sand, clay and rock.
Helical anchors are capable of withstanding significant loads, making them suitable for securing a variety of structures and equipment, including mooring lines for floating photovoltaic systems. Besides, it can be installed quickly and efficiently using specialized machinery, reducing the need for extensive physical labor.
Screw anchor piles we produced are with high strength:
Material: Q345B/Q355B seamless pipe and steel.
Surface: H.D.Galvanized with thickness ≥120μm.
During their fabrication, one or more steel screw threads are welded onto the shaft to enable sufficient downward force into the earth’s surface as it drilled into the surface.
All steel work will be done clear of excessive weld spatter.
The main characteristics of helical screw anchor:
Subsea Compatibility: Screw anchors are effective in a variety of subsea conditions, including sandy, muddy and soft soil, providing reliable mooring solutions for different marine environments.
Easy to install: Screw anchors can be installed quickly and efficiently, which is a great benefit for mooring lines in marine applications where ease of installation is critical.
Holding Capacity: Helical screw anchors are able to provide high holding capacity in a variety of seabed conditions, providing stability and security to mooring lines supporting floating photovoltaic systems.
Minimal environmental impact: Installation of helical anchors can often be accomplished with minimal disruption to the seafloor environment, making them a more environmentally friendly option compared to other mooring methods.
Re-usability: Spiral anchors can be disassembled and reused if required, providing flexibility and cost-effectiveness for marine PV mooring systems that may need to be relocated or adjusted.
Corrosion Resistant: Made of high-quality materials, the screw anchor is corrosion-resistant, extending its service life in harsh marine environments.
Applications:
Hot-dipped galvanized screw anchors are used across a wide field of marine mooring applications:
Boat moorings: Permanent and seasonal moorings for recreational and commercial vessels
Floating docks: Anchoring systems for residential, commercial, and marina docks
Piers and walkways: Foundation support for marine structures
Aquaculture equipment: Mooring of fish farms, mussel farms, and shellfish cultivation systems
Navigation markers: Securing buoys, beacons, and channel markers
Scientific equipment stabilization: Anchoring research platforms, weather buoys, and oceanographic instruments
Offshore “green” energy: Mooring for floating solar photovoltaic systems, wave energy converters, and other renewable energy installations
Pipelines: Securing subsea pipelines to the ocean floor—the original marine application for helical anchors
Seawalls: Reinforcing coastal protection structures
Floating photovoltaic systems
A notable emerging application is in floating photovoltaic (FPV) systems. Screw anchors provide high holding capacity across a variety of seabed conditions, offering stability and security to mooring lines supporting floating solar arrays while minimizing environmental impact on the seafloor.
Deepwater mooring
As offshore development moves into deeper waters, screw anchors are increasingly recognized for their cost-effectiveness and ease of installation. While deepwater projects have traditionally relied on suction caissons and vertically loaded anchors (VLAs), helical anchors offer attractive alternatives with lower installation costs and simplified procedures.
Transportation:
Each layer is insulated loaded with a wooden pad to prevent friction between screw anchors and damage to the galvanized surface.
