 1) Hydrostatic bearing of the Prins Willem Alexander Lock Gate in Amsterdam, NL

 This bearing is equipped with 4 pockets in order to obtain good self aligning
 properties ( Animation of pressure distribution ). An alternative is the hydrostatic
 bearing with one pocket at the center (calculator).
