Closure element for a pipe

摘要

The invention relates to an assembly (1) comprising an elongate pipe (5) which extends along a central axis (7) and a plug (6a,6b) which is arranged in or on the pipe and which exerts a sealing force on the pipe in order to seal an open pipe end in a fluid-tight manner. The invention relates in particular to elongate pipes in offshore-structures in which the pipes are used as foundation piles. These foundation pipes can, in practice, be over 80 metres long and weigh 400-600 tons. As the transportation of these elongate and heavy pipes is laborious, there is a need for an alternative.
