ABSTRACT

PT Wijaya Karya (Persero) Tbk is a company is engaged in

several sectors of engineering, procurement and construction

(EPC), trade, real estate and manufacturing. One of them a

department which engaged in EPC sector is an Industrial Plant

Department. The Department is implementing industry sectors

which include the sub areas of oil & gas and industrial facilities.

Now, the project is being worked is gas drilling Sumpal

Compression ConocoPhillips (Grissik) Ltd in South Sumatera.

This Project implements the High Integrity Pressure Protection

(HIPPS) as safety systems in gas wells. A level of system safety

can be determined by obtaining the value of Safety Integrity Level

(SIL) of the system through Probability Failure on Demand. So,

in this practical work was done for determining a value of SIL

HIPPS with Equation Simplified method. The results of the

determination of the value of SIL using SIL method is SIL 2 Based

on these values, the system has a high integrity level of safety and

protection.
