Scope
Scope: This document defines the terms and definitions related to the immersion launching of large and complex water supply pipelines in tidal areas, and stipulates the requirements for pre-construction preparation, pipeline fabrication, foundation trench excavation and treatment, immersion launching of pipelines, and project quality control. This document is applicable to offshore waters and river estuaries affected by tides, as well as large and irregularly shaped water supply steel pipes and the immersion launching of pipes using the floating method on the water surface. Other conditions for pipeline immersion launching can be implemented with reference to this document.
