Improvement of Position Keeping Performance and Its Effect on the Operation Rate in FPSO Tandem Offloading

摘要

The paper describes new dynamic positioning technology for a tandem type floating offloading system using a neural network. Effectiveness was verified by means of tank tests. A newly developed simulator is also described, which can evaluate the operation situation of an offshore floating production system, consisting of a production facility, a storage facility, a shipment facility, land equipment and transportation equipment for the system, as well as an FPSO and a shuttle tanker. The effects on total operation performance resulting from the adoption of such dynamic positioning technology for a tandem ofiloading system are evaluated by simulation for the northern area of the North Sea, the area offshore of Borneo and the area offshore of the Pearl River Basin.
