Engineering ServicesRoute Selection, pipelines are generally unable to follow the directtraight line route for many reasons, due to land/seabed obstructions,crossings, land/seabed.Hydraulic Analysis, pipeline diameter is sized for peak flow andensures that flow conditions and pressure drop are within acceptableranges. However, one must also check for low flow condition in casehis leads to laminar flow and corrosion at the bottom of the pipe willoccurred.Mechanical Design, the principle for wall thickness sizing is to make thewall thick enough to contain the maximum allowable operating pres-sure, although there are many factors to take into account which maylead to the selection of a thicker wall.On-bottom Stability Analysis, this analysis is performed to ensure thatthe pipeline is stable on the seabed under the influence of extremeenvironmental conditions.Spanning Analysis, unsupported pipeline (Free Span Pipeline) be-tween two points will be subjected to a number of loads. These com-prise bending under its self weight, loads imposed by pressure, hydro-dynamic loading, etc.Global Buckling Analysis, this analysis is performed to analyze pipe-line susceptibility to both lateral and upheaval buckling. End expansionanalysis this analysis is performed to calculate pipeline expansionsdue to temperature, longitudinal stress, etc.Stress Analysis, this analysis is performed to check pipeline systemstresses such as hoop stress, bending stress, longitudinal stress, etcagainst their allowable stress limits stated in design code.Pipelay Analysis, this analysis is performed to check layability of thePipeline in S-lay or J-lay methods. This helps to ascertain the DerrickBarge or pipelaay vessel adequacy for pipelay operation. The PipelayManual provides max. wave Hs, required tension, barge roller supportconfiguration etc for the entire pipelay operation. The analysis is doneusing OFFPIPE (Static & Dynamic).SURF Analysis, this analysis is performed using the software - Orcaflex.It determine the required lay parameters (i.e. limiting seasates, re-quired tension etc.). Suitable modifications & precautions can madeand taken to be with in Design Limits of the SURF product.
