Scaffolding for CTEP Offshore Operations shall utilize tube and coupling (TCS) methods and components in compliance with the current version of the British Standard (BS) EN 12811 and the UK National Access and Scaffolding Confederation (NASC) TG20 with onsite inspection and approval prior to use.
The TG20 serves as technical guidance for BS EN12811 addressing specific issues for tube and coupling scaffolds in two volumes. Volume 1 specifies the basic scaffolds (having a standard arrangement) that require no special design, plus guidance for erection, dismantling, use and inspection. Volume 2 gives technical information and advice required for the engineering design of scaffolds beyond the range of Volume 1.
