Offshore Wind
The foundation is where an offshore wind turbine meets the part of the problem nobody can inspect. These articles cover floating foundation concepts and the anchoring systems that hold them, the cyclic and long-term soil response that governs their design life, and what it takes to monitor the structural health of installations too far offshore to visit casually.

Suction caissons: the suction needed, and the limit
A caisson needs 182.7 kPa of suction to reach depth and lifts its soil plug at 371.8 kPa. Installability is the ratio of those two, and it is 2.04 here.
Catenary mooring: chain length, tension and anchor load
A catenary anchor sees pure horizontal load while chain rests on the seabed — 412.3 m of it here, 1350 kN of tension at the top, 1200 kN at the anchor.
Monopile p-y curves: what PISA was needed to fix
At 35 degrees the API p-y transition sits at 16.96 diameters whatever the diameter. On an 8 m monopile that is 135.67 m, deeper than the pile itself.
