Abstract

Safety is an important aspect of the industrial process. Failure of system and mechanism endanger both human and environmental safety. Safety is obligated to be implemented precisely and thoroughly to prevent failure consequences. One of the preventive implementations is to map out safety devices in the form of SIS (Safety Instrumented System) and other layers of protection. However, to acknowledge this safety device performance used SIL (Safety Integrity Level). This final research is intended to analyze Fuel Gas systems on Onshore Receiving Facilities (ORF). HAZOP (Hazard Operability Study) as process hazard analysis with deviation during the operation so that the risk level is known. SIL verification towards SIL target is SIL-2 refer to IEC 61511 standards by FTA (Fault Tree Analysis) method. From the HAZOP study can be concluded that over-pressure becomes a top hazard to all nodes due to the most severe consequences, the highest likelihood (medium risk). The calculation result of PFDavg is Node 1 (Fuel Gas Scrubber V-6060) is 6,22E-03, Node 2 (Fuel Gas Filter Separator S-6060A) is 1,24E-03, Node 3 (Fuel Gas Filter Separator S-6060B) is 1,24E-03, Node 4 (Fuel Gas Superheater E-6060) is 1,21E-03, and Node 5 (Instrument Gas Receiver V-6070) is 2,23E-03. The conclusion of this research shows that five components of the Fuel Gas System fulfill the SIL-2 target, therefore, doing a re-design to add a safety device is unnecessary.

Abstract

In the work breakdown structure for shipbuilding of machinery outfitting is related to machinery, ducting, hvac & piping, steel work, and insulation. Integrated work breakdown structure is one of the shipbuilding methods involving in management, so that design time is shorter. The ducting, HVAC & piping is the system based on the contract assignment and drawing approval by classification society. Then, we compare the effect of each Time Estimation. Then, continue with combine product and project structure. Problem start with how do we compare old with new WBS technology, no optimization process, and no working breakdown structure for the outfitting in the engine room. Bar chart, combination of industrial and financial system with design software also program project evaluation and review technique methodology will be used. Results obtained a work breakdown structure for Guidelines. The Aim was for optimization process time. The schedule created compared with the actual schedule that occurs so that we can see there is a difference of time shows that the shipyard applies integration. This also will lead to man-hour optimization. It is concluded that an integrated work breakdown structure can be applied to obtain the shipyard design in a shorter time.
