| Abstract: |
| Security system of Jack-up drilling rig is a kind of protection system for the purpose of accident pre-caution, people and equipment protection and production benefit maximization on the premise of safety. This paper introduces the composition of the security system and its key index, the function design of the system and the methods used in safety integrity level calculation, where reliability block diagram is used in calculating the safety integrity level of the typical safety control process. |
