ABSTRACT:
A sealing device for sealing the gap between a tubular leg or a tubular piling can and a pile passing therethrough and supporting a permanent platform at sea, the sealing device comprising a first part in the form of an annular sealing element and a second part, through which the pile can pass, in the form of an annular protective guard for the sealing element, both parts being coaxial with the leg or can, the guard, before a seal is made with the pile, lying between the sealing element and the pile, there being means provided which, in use, enable such relative movement in an axial direction between the guard and the sealing element, that the guard no longer protects the sealing element which is thus free to make sealing contact between the pile and the leg or can.
