For Long distance onshore hydrocarbon transportation, the most economic recommend mode: Pipelines, Rail, Road tanker, Ship/Barge Right-of-way may use: Multiple lines, single line, none In the construction of the long-run cost function, the principal fixed cost components are as follows: Those that change with pipe diameter; Scheduled maintenance cost Break down maintenance cost Economic diameter is Directly proportional to specific gravity of fluid, inversely proportional to specific gravity of fluid does not have any effect. Economic diameter is Directly proportional to Viscosity of fluid, inversely proportional to viscosity of fluid, Does not have any effect. Presence of water vapors in gas, the Heat value of unit mass: Increases, decreases, no effect The facilities piping code is governed by: ANSI-[(B31.3), (B31.4) , (B31.8)], The liquid pipelines are governed by: ANSI-[(B31.3), (B31.4) , (B31.8)], The Gas pipelines are governed by: ANSI-[(B31.3), (B31.4), (B31.8)], Risers are constructed for Process/unmanned well platform fluid flow, Subsea completed manifold, onshore process plants Hydraulic Shock/ surge and Water hammering in Pipes Increases, Decreases, Does not have effect (on the design pressure). Compressibility factor is required for evaluation of power requirement for transportation of Liquid, Gas, solids Presence of water vapor in Ethane compared with pure Ethane, will (Increase, decrease, no effect) on compression power requirement Ductility in the pipeline material physical property is an indication of Brittleness, plasticity, yield strength A check valve shall have a closure member(s) (as ball or a flapper) permit fluid to flow In one direction only, in both directions, in none of the direction

For liquids, viscosity Decreases with increasing temperature, Increases with increase in temperature, no effect on change due to change in temperature Vapor pressure is The pressure exerted by the vapor in liquid phase in a confined container at a given temperature, The pressure exerted by the vapor phase of a liquid in a confined container at a given temperature, None of the above Vapor pressure Decreases with temperature, Increases with temperature, No effect due to change of system temperature After a weld is made, Does not matter later or earlier , It is examined to ensure integrity of the weld before laying into the trench; It is examined to ensure integrity of the weld before laying into the trench, Pipelines are coated primarily to protect them Against erosion, against corrosion, against expansion due to temperature variations.

J lay barge used for laying pipeline in Shallow water, Deep sea water, in both conditions, none of the conditions



The pipeline is to be put into operation Before commissioning of pipeline, After Pigging of pipeline, after certification that all relevant codes have been followed,
