Modelling of Hydrates in Subsea Pipeline

This thesis describes the modelling and simulation for the hydrates in subsea pipeline. For new developer, a better understanding on how the to calculate the heat transfer throughout pipeline using some formulae and equations is needed to ensure that the system flow will meet all design specifications and reduced the risk with installation and commissioning. Hence, simulating a model of subsea pipeline module provide engineers with the ability to do multiple scenario of pipeline based on changing parameters which are radius of pipeline and material of coating used for pipeline. The methodologies of project involve collection of technical details and date regarding subsea pipeline module, identify formulae and equation needed, method of calculation, and subsea pipeline module design parameters. Result shows that the best option for radius and material coating for subsea pipeline are radius option 5 (0.83 m) and Polibrid material since the surrounding temperature through heat transfer inside of the pipeline is not suitable for the hydrate to be form.
