Designing safety system for BK16 base on Grafcet

Authors: Phan Thị Huyền Châu*


The technology process in BK16 wellhead satelite platform is to separate the gas and the oil from gas-water mixture. Therefore, the contruction in BK16 is very dangerous due to the flammable and exposive posibility. In order to ensure the safety for people and equipment, it is obligation to set up the the safety system with absolute reliability and satisfies SIL 3 – safety level for BK16. The main function of this system guarantees that crude oil and gas are not leak, and if there has a leak the system will be reacted by closing or opening a series of valves such as: blowdown valve, process shutdown valve, emergency shutdown valve and monitoring the signals from level and presure sensors of production separate tank to minimize losses. To reduce design time and programming, Grafcet method is applied because of the characteristics of safety system is to control many of ON-OFF valves.
