A pipe-in-pipe assembly workstation is disclosed for assembling inner pipe and outer pipe in a pipe-in-pipe configuration. The workstation may be provided on a pipelay vessel having two pipe string manufacturing lines and a firing line, wherein the pipe string manufacturing lines are designed for simultaneously handling two different pipe outer diameters for use as the inner pipe and outer pipe respectively. The vessel is designed with a lay-out which allows for producing offshore pipe-in-pipe strings from single joints, wherein available space is optimally used and pipe-in-pipe strings can be produced safely offshore.
