Redesain Pipe Support Location Jalur Outlet Gas 2nd Stage Gas Lift Suction Scrubber Menuju Suction 2nd Stage Gas Lift Compressor Akibat Clash
type: item
description: This study presents the stress analysis and redesign of the 12”-PG-B1-2303 piping system within the gas compressor module of the Forel FPSO Time Charter project. The modification was necessary due to a clash identified during construction between the pipe support and two adjacent lines connecting the outlet of the second gas lift scrubber (23 MBF-002) to the inlet of the second compressor package (23 CAE-002). Limited H-beam locations and restrictions on direct deck installation required repositioning of the support. The allowable pipe span was evaluated using the Kellog, Kannappan, and Timoshenko methods, with the minimum allowable span of 14.779 m adopted as the design reference. Static stress analysis, conducted in accordance with ASME B31.3, confirmed the structural integrity of the system. The support was relocated 1.021 m along the X-axis, producing maximum stresses of 8670.2 psi (43.4% allowable) for sustained load, 9946.5 psi (37.4%) for occasional load, and 4565.5 psi (15.2%) for thermal expansion. Nozzle load verification yielded forces of 1560 lb and 1755 lb, with corresponding moments of 8343.8 lb-ft and 7859.9 lb-ft for the scrubber outlet and compressor suction, respectively. Material Take-Off (MTO) estimation resulted in a cost of IDR 194,387,569. The findings demonstrate that all stress and displacement values remained within allowable limits, validating the reliability and compliance of the redesigned configuration under ASME B31.3.

Pemodelan Jalur Pipa Tambahan dari Gas Boot Menuju Wash Tank Future Untuk Meningkatkan Distribusi
type: item
description: This study aims to design an efficient fluid distribution system by adding a pipeline branch from the gas boot to the future wash tank in the oil and gas industry. The existing pipeline (PL-0008-A013-6") lacked a pump, relying only on gravity flow, which was insufficient for future expansion. The research utilized PDMS for 3D modeling and combined manual calculations with Pipe Flow Expert software to determine the total pump head, yielding results of 16.2398 m (manual) and 16.3336 m (software). A centrifugal pump (Pioneer SPHFGS6-006- S) with 22 kW power and 57% efficiency was selected to achieve the required flow rate of 0.0350 m³/s. The design ensures operational reliability while adhering to safety standards. Future work may include stress analysis and vibration studies for further optimization.

Redesain Pipa Dan Redesain Support Pipa Pada Sistem Perpipaan Line Outlet Condensate Pada Tank 190D-16 Akibat Tank Settlement
type: item
description: The piping system in Crude Palm Oil (CPO) storage facilities is crucial for smooth distribution and safe operation. A key challenge is soil settlement around tanks, which can increase pipe stress and nozzle loads, risking overstress, deformation, or failure. Analysis of the existing design with a simulated 160 mm settlement showed critical stress levels: sustain loads peaked at 37.09 N/mm² (S4) and 24.54 N/mm² (S5), while thermal expansion loads reached 2878.65 N/mm² (S1) and 2943.53 N/mm² (S3), far above allowable limits due to load concentration at elbows. Although occasional loads were within limits, nozzle loads for Mx and Mz exceeded standards at just 61.75 mm settlement, proving the design unsafe. This study evaluates settlement impacts, determines safe pipe support spans, and proposes a redesign. Using stress analysis software based on ASME B31.3 and API 650 standards, the redesign achieved compliance with all limits: sustain and occasional stresses of 24.60 N/mm², and thermal expansion stress of 129.91 N/mm² at node 650. The N4 190D-16 nozzle loads also met criteria, confirming the redesigned system is safe under settlement of up to 160 mm over 25 years.

type: item
description: Liquefied Petroleum Gas (LPG) is flowed from the cold fresh separator to the heat exchanger via a centrifugal pump in a piping system at a temperature of −101°C and a pressure of 435 psig. This path is classified as critical and is analyzed using stress analysis software to evaluate stress, nozzle load, and natural frequency. The shortest pipe span of 22,5 feet was selected based on deflection limits for safety considerations. Initial results showed sustained (24576,5 psi) and occasional (28811,2 psi) stresses at Node 470 exceeded ASME B31.3 limits, while expansion stress at Node 850 (7865,9 psi) remained within the allowable range. After support modification, sustained and occasional stresses were reduced to 2108,4 psi and 4101,4 psi. Nozzle load on the pump remained within API 610 M limits, while the heat exchanger initially exceeded API 662-2 limits; both became acceptable after support adjustment. The initial natural frequency of 2,298 Hz was insufficient, but increased to 8,028 Hz post- modification, meeting DNVGL-RP-D101 (2017) criteria.

Perencanaan Inspeksi Pipeline 30 Inch Sales Gas Kilometer Point 0+00 Sampai Kilometer Point 10+905 Menggunakan Metode Risk Based Inspection Berdasarkan Api 581
type: item
description: A 30-inch gas pipeline spanning 22.9 km and in operation since 2014 is a vital national infrastructure for transporting natural gas from exploration sites to processing facilities. The metallic material of the pipeline is prone to corrosion due to chemical reactions with gas components, potentially leading to wall thinning and reduced structural integrity. Although designed with a corrosion allowance, varying corrosion rates across locations require regular inspection. Given that much of the pipeline is underground, a risk-based inspection (RBI) approach offers a more efficient alternative without excavation. This study aims to identify pipeline segmentation, potential damage mechanisms, Probability of Failure (Pf), Consequence of Failure (Cf), and overall risk level from KP 0+000 to KP 10+905. The results show the pipeline is divided into 43 segments, with thinning and external damage as the main failure mechanisms. The highest PoF is found in segment 6 at 0.1396 failures/year, and the highest Cf is in segment 32 at USD 136,587 per incident. Segment 6 falls into a medium-risk category, while all other segments are categorized as low risk. Planned inspection in 2026.

Analisis Kinerja Proyek Pembangunan Fuel Storage Tank 2×250 KL Dengan Metode Earned Value Management
type: item
description: A coal mining constructed two fuel storage tanks with a capacity of 250 KL each. The mechanical and piping works were considered as the contractor’s main responsibilities. The project was initially planned to be completed within three months, from October 2024 to January 2025. However, during implementation, delays occurred that resulted in both time and cost deviations beyond the allocated schedule. At the end of the contract period, construction progress had reached approximately 89%, leaving 11% unfinished. Given the initial delays and the inability to complete the project within the scheduled timeframe, it became necessary to evaluate and analyze project performance. The Earned Value Management method was applied to address indicators of performance deficiencies. Two EVM indicators, Cost Performance Index and Schedule Performance Index, were used to assess project delay and cost overrun. The analysis results show that the CPI value of both tanks was 0.72, and the SPI value was 0.91. A CPI value below 1 indicated cost overruns, while an SPI below 1 indicated project delays. Based on the Time Estimate, the project was expected to require an additional 18 days, bringing the total duration to 109 days with an additional cost estimate of Rp1,135,971,875.89.

Thermal Stress Mitigation Through Three-Dimensional Expansion Loop Design On Piping Line PL-1018-A
type: item
description: Thermal expansion due to fluctuating operating temperatures presents a major challenge in industrial piping systems, particularly at critical connections such as nozzles and flanges. This study analyzes line pipe PL-1018-A in the test tank facility of Gathering Station A, South Sumatra, which transports crude oil at 200°F and is classified as a critical line. To mitigate excessive thermal stress, a three-dimensional expansion loop was designed to absorb multi-axial displacement within limited space. The stress evaluation followed ASME B31.3 standards and included span analysis, loop dimensioning, displacement, and stresses from sustained, thermal, and occasional loads, as well as nozzle load and flange leakage assessments. Results indicate a maximum support span of 28.04 ft and an expansion loop dimension of 24 in × 56.49 in. Recorded stress values for sustained (11,616.1 psi), thermal (4,071.6 psi), and occasional loads (22,876.5 psi) remained below allowable limits. Thermal displacement did not exceed 100 mm, and all nozzle and flange stress components were within allowable ranges specified by the manufacturer and ASME Section VIII Div. 1. Thus, the proposed design is technically feasible and ensures safe operation under analyzed conditions.

type: item
description: The Aircraft Refueling Depot (DPPU) is a facility that has various operational support systems, one of which is a fire protection system. In the shelter pump area, the only fire protection system currently available is a sprinkler system. This condition poses a potential risk if a fire spreads to the area around the pump shelter, considering that there is no additional fire extinguishing system in accordance with the provisions of the Decree of the Minister of Manpower of the Republic of Indonesia No. KEP.186/MEN/1999. Therefore, it is necessary to add a fire extinguishing system in the form of a hydrant pillar to increase the effectiveness of firefighting and strengthen protection for the area. The scope of this study includes the redesign of the fire extinguishing system piping in accordance with NFPA 13, NFPA 14, NFPA 20, and NFPA 24 standards. In addition, an analysis was conducted on the calculation of water capacity requirements, pump pressure (head pump), and pump power, both manually and with the aid of technical software. Based on data processing, 14 pillar hydrant points and 32 sprinkler head points were obtained. The total water requirement for the fire extinguishing system is 593 m3 . The total head calculation manually is 135.125 m, while the calculation using software shows 139.407 m. Translated with DeepL.com (free version) This design is expected to significantly increase the effectiveness and coverage of the fire protection system.

Perancangan Horizontal Pressure Vessel Tipe Preheater Dan Sistem Perpipaan Pada Proyek Blawan Ijen Geothermal Unit #1
type: item
description: The Blawan Ijen Unit 1 Geothermal Power Plant (PLTP) project in Bondowoso Regency, East Java, utilizes geothermal energy potential as a sustainable renewable energy source. One of its vital components is a preheater, a horizontal pressure vessel that functions as a heat exchanger to increase the temperature of the cyclopentane working fluid before the energy conversion process takes place. With a capacity of 21,000 liters, a design pressure of 3.2 MPa, and a design temperature of 210°C, this preheater is designed in accordance with international standards ASME Section VIII Division 1 using material SA-516 GR 70, with the assistance of PV Elite software for pressure vessel analysis and CAESAR II for piping stress analysis. Manual calculations were performed as validation of the software results. The minimum shell and head thicknesses were determined to be 16.529 mm each, with a Maximum Allowable Working Pressure (MAWP) of 4.1 MPa and a Maximum Allowable Effective Pressure (MAEP) of 0.162 MPa (shell) and 1.556 MPa (head). The MAEP values meet the design limits without the use of stiffener rings. The saddle strength analysis yielded a stress of 173.33 MPa, below the material's allowable stress limit. Of the 8 nozzles designed, 6 required reinforcing pads, and all welded joints met the strength standards for operational loads. The stress analysis using the von Mises stress value of 27.579 MPa is considered safe as it remains below the material's allowable stress limit. The nozzle inlet load analysis shows a maximum pressure of -281 lb,lower than the maximum allowable limit of 4496 lb, while the outlet shows a value of 3843.5 lb/ft, which is lower than the maximum limit of 29503.7 lb/ft, ensuring the pipe-nozzle connection is safe with the addition of Thermal Movement on the Dy axis of 2.2 mm and Dz of 4.5 mm at the nozzle inlet, For the nozzle outlet axis, the addition is Dy 0.27 mm, Dz 3.22 mm.

type: item
description: Rantau Field is one of the oil and gas fields operated by PT Pertamina EP, consisting of several active structures. Based on inspection results, Tank T-407 was declared unfit for operation due to peeling paint and perforations in the wall plates. Therefore, a new storage tank with a capacity of 1,600 BBLS is planned for construction at SP-IV Rantau Field using carbon steel ASTM A283 Grade C. The design follows API Standard 650, 13th, March 2020, applying the one-foot method. From calculations, the minimum shell plate thickness for courses 1 to 5 is use 6 mm because since all values are less than 6 mm, a thickness of 6 mm is adopted according to API 650 requirements, which specify a minimum of 6 mm for tank diameters between 6 m and 36 m. The bottom plates are designed with a thickness of 9 mm, and the roof plates 8 mm. Stability analysis shows the tank is stable without anchorage. A 3D model and finite element analysis produced an equivalent stress of 26.773 MPa and deformation of 0.9412 mm. Both are within allowable limits for ASTM A283 Grade C. The estimated construction cost of the 1,600 BBLS tank is IDR 3,177,048,387.00

Efektivitas Metode Dual Shift Terhadap Percepatan Proyek Pemasangan Gate Valve Dalam Kondisi Online Service (Hot Tapping)
type: item
description: Construction project planning requires close attention to time, cost, and quality as key success factors. This study examines the installation of a gate valve and a bypass pipeline under online service conditions using the hot tapping method on the Zamrud–Minas shipping line in Pekanbaru, Riau. The project experienced delays due to design changes in the bypass route and technical challenges during construction. To address these issues, the bypass was redesigned to improve fluid distribution. A Work Breakdown Structure (WBS) was prepared to support structured management, and rescheduling was conducted using the Precedence Diagram Method (PDM) to identify the critical path. Crashing techniques were applied through a dual shift scenario. The analysis showed that the normal schedule had the lowest direct cost of IDR 4,329,000,000, while dual shift required IDR 4,536,550,000 due to additional labor and material expenses. Indirect costs such as home and field offices, temporary facilities, and insurance remained constant, but project tax increased with total cost—IDR 476,190,000 (normal) and IDR 499,020,500 (dual shift). If project acceleration is highly urgent, dual shift becomes the most suitable option, reducing the project duration from 170 days to 97 days, although with higher expenditure compared to the normal schedule.
