Pontoon or platform (1) for underwater drilling, comprising a work section (3) designed to support equipment necessary for drilling (13) even inlets (15) for access to it for drilling in the seabed (21) as well as support legs (9) for anchoring the pontoon in connection to the current drilling site. According to the invention, the pontoon is characterized by the work section's (5) fixed joined ballast part (5) shaped like a tank, through which the pontoon can be taken into an underwater position between the surface of the water (19) and the seabed (21), through which non-desired movements of the pontoon (1) as a result of motion on the surface of the water are avoided.<IMAGE> |
