Abstract

In the upstream oil and gas industry Slug Catcher is a separator to separate heavy liquid hydrocarbons and the gaseous lighter fraction. Slug Catcher is a cylindrical pressure vessel which has a horizontal orientation designed with an internal pressure of 84.37 kg/cm2 , 73,89 °C temperature, 3 mm corrosion allowance, 3,500 mm length, and 1,750 mm diameter. This paper aims to design a Slug Catcher from a mechanical side that is safe and able to withstand the stress caused by internal pressure. General design which includes calculation of thickness of shell, heads, and nozzles, maximum allowable working pressure (MAWP), and minimum design metal temperature (MDMT) using ASME BPVC Section VIII Division 1. Based on the results obtained the nominal shell thickness is 60 mm, head minimum thickness 58 mm, material specification for shell and head is SA 516 Gr 70. In general, the selected material use low carbon steel; flange rating class 600; vessel’s Maximum Allowable Working Pressure is 87.60 kg/cm2 ; hydrostatic test pressure is 113 kg/cm2 .

Abstract

PT Geo Dipa Energi (Persero) unit Patuha menggunakan Auxiliary Cooling Water Pump (ACWP) jenis double suction centrifugal pump. Auxiliary Cooling Water Pump (ACWP) merupakan komponen dalam sistem pendingin sebuah instalasi industri terutama panas bumi. Pompa ini berfungsi untuk mengalirkan air pendingin ke berbagai peralatan dan komponen yang membutuhkan suhu operasi optimal. Namun, performa pompa dapat terganggu akibat masalah teknis seperti terjadinya vibrasi yang tinggi. Vibrasi yang tinggi pada Auxiliary Cooling Water Pump (ACWP) merupakan indikasi adanya masalah yang perlu ditangani. Faktor vibrasi yang tinggi menjadi pertanda kerusakan pada bantalan (bearing) dilihat dari spektrum, maka dari itu untuk mengatasi masalah tersebut dilakukan proses perbaikan dengan metode inspeksi atau pemeriksaan visual dilanjutkan dengan pemeriksaan kondisi menggunakan alat bantu vibration analysis untuk meningkatkan pemahaman mengenai penyebab vibrasi tinggi dan langkah mitigasi yang tepat untuk menjaga performa Auxiliary Cooling Water Pump dan menjamin kelangsungan operasional sistem secara keseluruhan. Metodologi yang digunakan dalam penelitian ini yaitu pencatatan data harian pada Auxiliary Cooling Water Pump (ACWP) untuk dilakukan analisis perhitungan daya motor,daya pompa,dan efisiensi. Penurunan performa pompa yang diakibatkan oleh vibrasi tinggi akan berdampak langsung pada keseluruhan sistem pendingin. Akibatnya, peralatan lain yang bergantung pada suplai air pendingin dari pompa tersebut dapat mengalami overheating bahkan shutdown jika masalah ini tidak segera ditangani. Dari hasil perhitungan didapatkan daya motor ketika terjadi vibrasi yang tinggi yaitu 141,68 kW dan efisiensi pompa 73,57% sedangkan hasil daya motor setelah dilakukan perbaikan yaitu 159,15 kW dan efisiensi pompa 81,12%. Efisiensi pompa mengalami kenaikan setelah dilakukan perbaikan sebesar 7,55%.

Abstract

Occupational Safety and Health (OSH) is indispensable to the oil and gas sector, which encompasses production, processing, and transportation, due to its substantial risk of workplace accidents and fires. Oil and gas OSH is a regulation that ensures the reliable operation and safety of oil and gas institutions/companies by standardizing equipment, personnel, general protocols for oil and gas installations, and operational procedures. OSH certification is a highly regarded indicator of documented expertise and is highly regarded for its credibility. The process of implementing this OSH training and certification involves the identification of training requirements, the preparation of a curriculum, and the coordination with relevant parties, specifically the Bojonegoro Regency Government. Preparation of socialization from participant registration through the selection of participants based on their basic requirements or qualifications. Theory sessions and practical sessions comprise training implementation. The theoretical session involves the delivery of material in the classroom, while the practical session involves the simulation of tool use in the fire and safety laboratory. In collaboration with LSP PPSDM Migas, the STTK certification exam for operator level was administered. The National Professional Certification Agency (BNSP) issues certificates. A total of 25 participants took the STTK exam on 8-9 August 2024, with 23 of them being declared competent and passing. The certification exam for the operator level was administered in conjunction with LSP PPSDM Migas. Furthermore, an additional examination was administered on August 27-28, 2024. Thirty-one individuals were declared competent and successfully completed the certification, out of a total of fifty.
