Summary

This guidance has been written to assist both operators and contractors in reducing the risks to divers when undertaking work on or alongside pipelines. Typically, these tasks may involve pressure testing, damage inspection, span rectification and handling of protection mattresses. When planning such tasks, hazard identification and work control are critical, especially in connection with pressure testing and provision of adequate isolation.
