The key element to operates entire pipeline system in safety and within optimum allowable range when delivering the liquid is to managing the risk of flow assurance and ensure the system operates as expected. ALFAsim is a 1D dynamic multiphase flow simulator which resulted as the natural evolution of the simulation technology developed for its preceding well and pipeline flow simulators. It combines a robust mathematical formulation with an advanced numerical strategy to deliver a computationally efficient simulation experience in an intuitive interface. Simulations are set up and launched in a modern workspace environment and the results are plotted in a versatile and intelligent manner by featuring simple, fast, and user-friendly sequential steps for pre- and post-processing.
