Minerals Management Service Pipeline Oil Spill Volume Computer Model. User's Manual

摘要

The Pipeline Oil Spill Volume Computer Model (POSVCM) provides a methodology to estimate discharges from seafloor pipelines. The system is composed of a Release Module and a Nearfield Module, linked together with necessary databases through a Graphical User Interface (GUI). This document describes the use of POSVCM. Inputs to the model are parameters describing the configuration and characteristics of a pipeline system, the fluid it contains, and the leak or break from which the discharge occurs. Key outputs are the evolution of the release rate over time, the total mass of oil released, and a measure or the mean thickness of any eventual surface slick being formed.
