An operator-only joint industry project worked to develop an integrated approach to the integrity management of subsea, umbilical, riser, and flowline systems and best practices. Among the JIP’s goals were to identify technology gaps by surveying existing and emerging inspection and monitoring techniques and compare them to integrity management needs. The participants shared field experience in the development of various technologies and compared their effectiveness.
The removal of oil from water in a water treatment system is discussed. The article presents a review of basic droplet formation due to shearing from pipes, valves, and pumps and gives practical advice on how to reduce the shear in pumps and valves and mitigate the effect of shear. It is intended to remind engineers that the decisions made upstream can have a grave consequence on downstream separation equipment performance. Sources of shear, the relative magnitude of shear, and the consequence on the oil droplet size are explained.

Sand and solids are removed from production separators either offline or online by use of jetting systems. Traditional jetting designs use spray nozzles to fluidize and push the sand toward a covered outlet to evacuate the solids from the vessel, but cyclonic-jetting technology combines the fluidization and evacuation functions into a single, compact device. The integration and operation of a jetting system with transport, dewatering, and disposal stages of facilities sand management are presented as guidelines for designing such a system.
The deployment plan and communication architecture of vertical takeoff and landing unmanned air vehicles (UAVs) for pipeline monitoring are presented, whereby the pipeline network is divided into wide area cells, and each cell is controlled from a facility. Low-power UAVs with directional antennas and long-range zoom cameras are deployed quickly to provide real-time monitoring of a pipeline section whenever a pressure drop or significant
third-party activity is detected.
