Flexibly embedded plate anchor (FEPLA)
Adapting anchor design for floating wind and mixed soil conditions
The FEPLA (flexibly embedded plate anchor) is Acteon’s next-generation anchoring solution for floating offshore wind. Based on proven plate anchor principles, it introduces a new embedment system that works across a wider range of soil types - including sand, clay and mixed layers.
FEPLA anchors are significantly lighter and faster to install than piles, reducing carbon footprint and simplifying logistics. With no need for high bollard pull or anchor proof loading, the FEPLA is ideal for areas with limited geotechnical data or sustainability constraints.

How the FEPLA works
The FEPLA anchor system uses a hybrid embedment method that combines vibro hammering and impact hammering. This dual-mode approach allows rapid, reliable anchor embedment across a broad range of seabed conditions - from clay to sand and mixed soils.
The system includes two dedicated plate anchor configurations:
- An updated SEPLA-style plate for soft clays
- A new optimised design for sandy seabeds
Both anchor types interface with a multi-function follower that can switch between vibro and impact modes depending on soil resistance. This eliminates the need for high bollard pull or deep proof loading, and significantly reduces project risk in areas with limited geotechnical data.
Once installed, FEPLA anchors can be removed at end-of-life to minimise environmental footprint and support site reuse - making them well-suited to floating wind farms and other low-impact mooring strategies.
Quite possibly the ideal anchor
The FEPLA hybrid embedment system provides versatility, lower anchoring costs and simplified logistics.
Lowering costs and accelerating installation
The FEPLA reduces installed anchor cost by up to 50%, with installation times up to 30 - 50% faster than piles. No proof loading is required, and each unit installs in half the time of a comparable foundation.
Reducing weight and simplifying logistics
Up to 70% lighter than piles, FEPLA anchors are easier to fabricate and ship. They enable the use of smaller vessels and more local supply chains - reducing time, cost and risk.
Adapting to soil conditions and minimising environmental impact
FEPLA anchors are suitable for a wide range of soil conditions and flexible with varying soil layers, reducing risks associated with limited geotechnical data. Its low-noise installation and removability reduce seabed disruption and carbon footprint by 60-70%.
