Abstrak:
Dalam operasi industri migas lepas pantai instalasi pipa bawah laut digunakan sebagai moda transportasi untuk memindahkan produk migas dari satu tempat ke tempat lainnya, operasi pipa bawah laut tersebut tidak lepas dari bahaya dan resiko yang bisa disebabkan oleh berbagai faktor. Mayoritas kegagalan pipa bawah laut terjadi disebabkan karena kegagalan dalam mengenali bahaya dan tidak adanya mitigasi bahaya yang tepat. Kegagalan tersebut dapat dicegah melalui suatu metode manajemen risiko keselamatan dan salah satu tahapan dari manajemen risiko tersebut adalah penilaian risiko. Pipa memiliki kerentanan dalam mengalami kerusakan yang dapat mengakibatkan berbagai insiden keselamatan yang berdampak pada keselamatan manusia, pencemaran lingkungan, serta bisnis perusahaan. Penelitian ini bertujuan untuk melakukan penilaian risiko pipa bawah laut 20 inchi yang berlokasi di perairan Kalimantan Timur milik PT.X pada fase operasi. Penelitian ini merupakan penelitian kuantitatif dengan menggunakan data sekunder yang didapatkan dari dokumen PT. X. Metodologi penilaian risiko pipeline (DNV-RP-F107) digunakan untuk mengidentifikasi risiko. Dari hasil analisis yang dilakukan dalam penelitian ini, didapatkan bahwa penilaian Risiko pada Pipa utama 20 penyalur MIGAS PT X telah dilakukan pada skenario kejatuhan dan terseret jangkar, kebocoran pipa, dan kapal tenggelam dengan hasil penelitian menunjukan risiko yang masih bisa diterima (acceptable/minor risk). Mitigasi yang telah dilakukan oleh PT X dalam mengoperasikan pipa 20 untuk terus dipertahankan agar risiko pada ketiga skenario yang diteliti dapat terus terkontrol dan berada pada tingkat risiko yang rendah/dapat diterima
In offshore oil and gas industry operations, underwater pipeline installations are used as transportation to move oil and gas products from one place to another, the underwater pipeline operation cannot be separated from the dangers and risks that can be caused by various factors. Most subsea pipeline failures occur due to failure to recognize hazards and the absence of proper hazard mitigation. These failures can be prevented through a safety risk management method and one of the stages of risk management is risk assessment. Pipes have a vulnerability to damage that can result in various safety incidents that have an impact on human safety, environmental pollution, as well as the company's business. This study aims to conduct a risk assessment of the 20-inch submarine pipeline located in the waters of East Kalimantan belonging to PT.X in the operation phase. This research is a quantitative research using secondary data obtained from PT. X. A pipeline risk assessment methodology (DNV-RP-F107) will be used to identify risks. From the results of the analysis carried out in this study, it was found that the Risk assessment of the 20 main pipeline for oil and gas distributor PT X had been carried out in the scenarios of falling and being dragged by anchors, pipe leaks, and sinking ships with the results of the study showing acceptable risks. The mitigation that has been carried out by PT X in operating the 20 pipe is to be maintained so that the risks in the three scenarios studied can be controlled and are at a low/acceptable level of risk

Abstrak:
Latar belakang Salah satu kegiatan dalam industri pengolahan minyak dan gas adalah transfer minyak bumi, gas alam, dan/atau hasil bensin melalui pipa. Kegiatan ini memerlukan program manajemen (seperti perencanaan, pengawasan dan inspeksi, serta pemeliharaan peralatan) karena pipa memiliki potensi bahaya terhadap lingkungan seperti kebakaran, ledakan atau kontaminasi lingkungan. Tujuan studi ini meneliti penilaian risiko secara kuantitatif dan kualitatif untuk pipa bawah laut. Model yang digunakan adalah referensi untuk DNVGL RP F-107 Recommended Practice Risk Assesment of Pipeline Protection. Bahwa 42,6 % terkait dengan procedure/drawing/plan yang mana merupakan risk yang paling significan dan 29,6% terkait dengan program-program yang akan diimplementasikan oleh Perusahaan. Berdasarkan scenario kejatuhan dan tergaruk jangkar, level kerusakan berada pada level D3 (level damage) tepatnya masih bersifat tolerable jika ALARP, yang berarti dibutuhkan adanya pengurangan risiko untuk menurunkan residual risk. Sesuai dengan hasil studi penilaian risiko maka direkomendasikan untuk melakukan pelapisan pipa dengan lapisan beton dan dilakukan pemendaman. Kata kunci : Kuantitatif dan penilaian risiko kualitatif, keselamatan, pipa, orang, kerugian

Penelitian ini bertujuan untuk menganalisis risiko pipa bawah laut milik PT. AZ yang terdampak proyek reklamasi kilang PT.XY berlokasi di perairan Jawa Barat. Menggunakan penilaian risiko proteksi pipa bawah laut DNVGL-RP-F107, penelitian memperhatikan Skenario Bahaya Besar yang teridentifikasi, yaitu: kejatuhan jangkar (dropped anchor) dan pengerukan tanah (soil excavation). Objek penelitian difokuskan pada pipa bawah laut berdiameter 12 dari GG A ke OPF (Onshore Processing Facilities) dalam kondisi terkubur dengan tingkat kedalaman 2 meter dari KP 24,6 ke KP 34,713 dekat area Reklamasi kilang seluas 280 Ha. Penelitian menggunakan data sekunder yang melingkupi karakteristik dan properti pipa bawah laut, karakteristik kapal serta jangkar yang melintas, dan aktivitas pengerukan Jawa Barat. Pendekatan yang digunakan adalah kuantitatif deskriptif analitik yang mengutamakan indepth-analysis. Hasil penelitian menunjukkan konsekuensi dropped anchor mendapat level kerusakan pipa D1, yang artinya tidak diperlukan tambahan safeguard untuk menurunkan residual risk. Untuk penilaian risiko soil excavation nilai initial risk yang dihasilkan adalah 9 (medium) dengan tingkat kerusakan D3 sehingga direkomendasikan safeguard tambahan untuk menurunkan residual risk menjadi Tolerable (ALARP). Beberapa saran ditambahkan untuk menjamin keselamatan operasi pasca proyek

Abstrak:
Tesis ini membahas mengenai penilaian risiko kesehatan berdasarkan task analysis pada aktivitas well services industri pengeboran minyak bumi di PT X Tahun 2019. Penelitian ini adalah penelitian semikuantitatif dengan desain deskriptif berdasarkan HRA model PT Pertamina (2018) berdasarkan factor tingkat pajanan dan tingkat. Langkah awal yang dilakukan adalah dengan mengidentifikasi aktivitas well services berdasarkan task yang ada pada SOP dan JSA, walkthrough survey dan menilai risiko. Berdasarkan penilaian risiko kesehatan didapatkan tingkat risiko tinggi (high) untuk bahaya bising terhadap SEG floorman, driller, derrickman, dan mechanic dan bahaya ergonomi terhadap SEG floorman, driller, derrickman, dan operator dozer. PT AB dan PT CD perlu melakukan pengendalian tambahan terhadap bahaya bising dan bahaya ergonomi antara lain: Hearing Loss Prevention Program (HLPP), audit terhadap SOP & peralatan, melakukan pengukuran dosis personal bahaya bising, pembatasan jam kerja, pengukuran audiometri, melakukan supervisi dilapangan terhadap pengunaan earplug, pengunaan double earplug & earmuff, melakukan sosialisasi bahaya bising secara konsisten, menyediakan perancah (scafolding) pada aktivitas nipple up & nipple down horse head, melakukan pelatihan posisi tubuh yang ergonomi serta menambahkan Ergonomic Postur Assessment sebagai salah satu item dalam pemeriksaan kesehatan berkala. Bahaya gas H2S terhadap SEG floorman, driller dan derrickman dan bahaya gas CO terhadap SEG mechanic mendapatkan tingkat risiko medium, sehingga perlu dilakukan pemantauan implementasi pengendalian yang sudah ada serta pengendalian tambahan secara konsisten. Selanjutnya bahaya getaran mendapatkan tingkat risiko low terhadap SEG mechanic dan bahaya gas O2 terhadap SEG floorman, driller, derrickman, mechanic dan operator Dozer mendapatkan tingkat risiko very low, oleh karena itu PT AB dan PT CD melalui HES departemen perlu melakukan monitoring secara berkala dan konsisten terhadap impelementasi pengendalian yang sudah ada. Selain itu hasil penelitian ini juga menyarankan bahwa identifikasi potensi bahaya lainnya seperti pencahayan, radiasi gamma, heat stress, welding fume, bahaya biologi dan bahaya psikososial pada pekerjaan well services berdasarkan task analysis.
This thesis discusses the health risk assessment based on task analysis on the well services activities of the petroleum drilling industry at PT X 2019. This research is a semiquantitative study with a descriptive design based on the HRA model of PT Pertamina (2018) bases factor exposure level and hazard level. The first step is to identify performed the task well services based on SOP and JSA, walkthrough survey and risk assessment. Based on the health risk assessment, there is a high risk level for noise hazards to similar exposure group (SEG) floorman, driller, derrickman, and mechanic and ergonomic hazards to floorman, driller, derrickman, and dozer operators. PT AB and PT CD need to conduct additional controls for noise hazards and ergonomic hazards, including: Hearing Loss Prevention Program, auditing SOPs & equipment, measuring personal dose of noise hazards, limiting working hours, audiometric measurements, conducting field supervision of the use of earplugs, using double earplugs and earmuffs, disseminating noise hazards consistently, providing scaffolding for Nipple Up and Nipple Down Horse Head activities, conducting ergonomic body position training, and adding Ergonomic Posture Assessment as an item in periodic health checks. The hazard of H2S gas to the SEG floorman, driller and derrickman and the danger of CO gas to the SEG mechanic has a medium level of risk, it is necessary to monitor the implementation of existing controls as well as additional controls consistently. Furthermore, the vibration hazard gets a low risk level for the SEG mechanic and the danger of O2 gas against the SEG floorman, driller, derrickman, mechanic and Dozer operators get a very low risk level, therefore PT AB and PT CD through the HES department need to monitor regularly and consistently the implementation of existing controls. In addition, the results of this study also suggest that the identification of other potential hazards such as lighting, gamma radiation, heat stress, welding fume, biological hazards and psychosocial hazards in well-service work based on task analysis
