DETECTION OF CRACKS IN MARINE PLATFORM STRUCTURE

摘要

The present invention relates to a marine platform comprising a structure consisting of a lattice of tubular elements sealingly joined to one another. Pickups are provided on at least some of the tubular elements, to detect the passage of a fluid through the wall of an element. At a junction of one tubular element with another element whose interior space is monitored by a pickup, a backing plate is disposed in the one element facing the junction zone and sealed around the junction zone to define an intermediate space which is in communication with the interior space of the other element.
