Goes through · Preparation of piping layouts, isometrics, support Drawings; Responsibilities of piping engineer 1) Plot plan: 2) Equipment layouts: 3) Piping layouts: Review of process package: This activity is carried out prior to start the detail engineering to ensure availability of all the required process data by all engineering groups. This includes the following: 1) Process data required converting P & ID’s to piping layouts like a proper identification of valves, strainers, In-line instruments, 2) Utility summery giving utility consumption for each equipment with duty conditions like pressure, temperature etc., 3) Conceptual equipment layout drawings for process plant reflecting the process constraints. 4) Process data sheets for equipments. 5) Hazardous area classification etc.. Design planning: 1) Contract instructions, 2) Project design basis & scope of work, 3) Basic engineering Documents. 4) Site design data including facilities around the plot, 5) Contour & survey drawing, 6) Applicable codes, standards & statutory regulations, 7) Project schedule & network, With all this data plan the detail engineering activities. Basic engineering documents: · Plot plan; · Equipment layouts · Pipe rack study sketches; · Study piping layouts; · Piping isometrics; · GAD · Piping MTO; · Piping specification; · Utility distribution diagrams; · Line list & critical line list;
