A truncated elongated angular-, oval-, or part-angular-part-oval-shaped dry setting element having two elongated extremities, a first end, a second end and a sealing means, said truncated angular-, oval-, or part-angular-part-oval-shaped end being open and said second truncated angular-, oval-shaped or part-angular-part-oval-end being closed with a floor having a free edge, wherein said sealing means comprises a structure extending between said elongated extremities and the free edge of said floor, said sealing means being closed except for an open part which is adapted to accommodate part of a partially submerged structure, and has sealing elements along the edges of said open part of said sealing means; a dry setting installation (1) is provided for generating a substantially dry working space for carrying out work on part of a partially submerged structure, the dry setting installation (1) comprising a truncated elongated angular-, oval-shaped or part-angular-part-oval-dry setting element according to claim 1, which with said part of a partially submerged structure is capable of forming a cofferdam round said part of said partially submerged structure; a process for the treatment of part of a partially submerged structure, said process comprising the steps of: closing the above-described dry setting element with said part of said partially submerged structure, sealing said dry setting element on said part of said partially submerged structure thereby providing a dry setting installation; pumping the water out of said dry setting installation thereby providing a cofferdam round said part of said partially submerged structure; cleaning the surface of said part of said partially submerged structure; curing said curable adhesive coating, filling said dry setting installation with water, removing said dry setting element from said part of said partially submerged structure; and the use of the mobile dry setting installation as disclosed above for carrying out maintenance on parts of partially submerged structures. |
