Abstract

See full text

A pipe stalk for a pipe-in-pipe pipeline, said pipe stalk comprising an outer pipe and at least one inner pipe located within the outer pipe, and having retaining assembly moveable between a first configuration for preventing axial movement of the inner pipe with respect to the outer pipe in a downwards direction and a second configuration for allowing axial movement of the outer pipe with respect to the inner pipe, whereby axial movement of the inner pipe with respect to the outer pipe can be prevented when the outer pipe is held during welding to an adjacent pipe stalk. CAPEX and OPEX are reduced by reducing the time taken to join the ends of adjacent pipes and reducing the total number of welds required, and by avoiding the need for the use of half shells.
