Abstract
A bearing surface of a subsea foundation has a low-resistance coating such as an aerogel, an aero-clay or a polymeric film. When the foundation is installed, the bearing surface is embedded in the seabed soil using the low-resistance coating to reduce resistance movement of the bearing surface relative to the seabed soil. The coating may then dissolve or fragment away from the bearing surface or transform into a higher-resistance state while remaining on the bearing surface. These mechanisms degrade a resistance-reducing property of the coating to increase resistance to movement of the embedded bearing surface relative to the seabed soil. Suction may be applied to the foundation before or after the resistance-reducing property of the coating has substantially degraded.
