Stochastic dynamic optimization of an LNG-production plant

Abstract

This report opens with a presentation of the Snøhvit project and continues with a description of earlier work. A simplified nonlinear model from well to export ship of LNG production for Snøhvit is made in (Dahl 2007). The time of arrival for LNG ships is attended with uncertainty and is an important disturbance in production planning. There is some slack in tank capacity, but sometimes this spare storage space is not enough to compensate for late ships, and production must be reduced.
