Subsea Anchoring
Higher-capacity, lower-cost anchoring for floating wind and offshore facilities
Subsea Anchoring applies the Subsea Drive Riserless Casing Drilling System to install anchors for floating wind turbines and floating oilfield facilities. By adapting proven oilfield drilling technology, it sets anchors more securely than conventional methods — in any soil condition and at any seawater depth.
Because each anchor is drilled into place rather than dropped, driven, or suction-installed, the system provides significantly greater pullout (anchoring-resistance) capacity than current anchoring systems. Higher capacity per anchor means fewer anchors are needed for each floating platform, which minimizes the seafloor footprint of large mooring systems and reduces the capital cost of the structure.
Key benefits
Greater holding capacity — significantly higher pullout / anchoring-resistance than conventional anchors.
Fewer anchors per platform — higher capacity per anchor reduces the number required.
Any soil, any depth — effective across all soil conditions and seawater depths.
Lower seafloor impact — fewer, smaller mooring elements minimize disturbance to the seabed.
Lower capital cost — fewer anchors and less installation effort reduce overall structure costs.
Proven technology — built on the same riserless casing-drilling system used to construct deepwater wells.
Applications
