Development of Optimum Operation Method for Tank on LNG Receiving Terminal

摘要

We developed optimization providing efficient tank operation guidance on LNG receiving from cargo ships and on discharge consumption demand for LNG storage tanks at the Nihonkai LNG Co., Ltd., Niigata Receiving Terminal. The storage tank level has been suitably maintained and operation cost cut. Dynamic programming (DP) is applied to solve the optimization problem in 3 steps, greatly reducing calculation time. This system enables us to estimate long-term scheduling and is used for operator guidance and operations planning.
