Caisson and Prins Willem

Caisson
Caisson is a non-shipwreck dive from 100ft to 150ft.   The history of this caisson is unknown.  In geotechnical engineering, a caisson is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships.
