Colloquium Discussion on TP1: The Construction of Gas Treatment PlatformNo. 1 for the Frigg Field for Elf-Norge A/S by J.A. Derrington

Mr. D. E. Roe: The first problem that had to be solved was the erection of the riser pipes within the two columns. Fig 14 of the paper shows the congestion that there was in the columns, and this was made worse when the pipework was installed because of the amount of scaffolding inside the columns. A novel method was devised to overcome the lack of working space and to enable the pipework to be completed as soon as possible after slipforming the columns.
