Telemetry and control system for interplatform crude loading at the Statfjord Field
A control system for crude loading to tankers at the Statfjord field has been designed by Mobil Exploration Norway Inc. The objective of the interplatform crude tieline and control system was to allow tanker loading to take place at all times in order to prevent production shutdowns due to loading buoy problems. The control system has been designed to maximize the flexibility of loading operations and meet all safety and regulatory requirements. This paper discusses the design criteria for the crude tieline control system, and describes how these were met by utilizing fail safe telemetry equipment, hardwired permissive relay logic and programmable logic controllers (PLC's). The experience gained from more than three years of operation of the system is reviewed. The system has allowed maximum use of total field storage capacity while loading crude to 125000 DWT tankers nearly every day throughout the year. It has been possible to maintain a high production rate event through periods of difficult weather conditions as experienced in the northern North Sea.
