This document provides a summary of the scope of work for engineering design and installation of a new 10-inch, 22 km offshore pipeline from Palang to an FSO unit. The scope includes pipeline design, material selection, coating and cathodic protection design, engineering drawings, installation analysis using specialized software, and environmental and geotechnical data collection. Key deliverables are the wall thickness verification, free span analysis, anode design, and pipeline expansion calculation.
