But in some plastic pipe the wave speed can be lower than 200 m/s. The sonic velocity is also the speed at which the pressure waves generated by water hammer travel in the pipe.įor water in very stiff pipes the sonic speed could be as high as 1480 m/s. The sonic velocity is the speed of sound in the pipe and is determined by a modified hooks law formula which takes into account the stiffness of the fluid and the pipe wall. The magnitude of the water hammer pressure rise can be calculated using the Joukowsky equation which is Water hammer can generate very high pressure transients which could burst a pipe and can generate pipeline vibrations. Usually this occurs when a valve closes quickly. It is the special case when there is a sudden change in flow velocity.

Knowledge of Orcaflex software will be appreciated but not mandatory.Water hammer is part of the larger subject of transient flow or surge analysis.

Attention shall be taken to the vessel structural constrains.

The stinger, by supporting the pipeline on a longer distance, allows to reduce the requirement of tensioning of the pipeline, and thus to install pipeline in deeper water depths.

To control pipeline displacement when it leaves the installation vessel, a structure, called stinger, is installed at the vessel stern. This method allows laying pipe at high speed (rate) but in deep-water imposes large top tension capacity to prevent from too high strain in the pipeline. The name comes from the shape taken by the catenary during installation. One of the methods to lay offshore pipeline is called S-Lay. Multiple projects are on execution and several engineers are mobilized on each of them to execute the work. Pipeline Group is a service provider for the engineering of rigid pipelines and associated structures installation.
