Risk Assessment Offloading Kapal FLNG ke Kapal Shuttle Tanker

Floating Liquefied Natural Gas (FLNG) adalah bangunan terapung yang berfungsi sebagai fasilitas eksploitasi, produksi dan pencairan gas alam. LNG dicairkan dengan suhu -160 °C pada tekanan 14,7 psi sehingga volumenya tereduksi 1/600 fasa gas. FLNG memerlukan proses transfer, untuk memindahkan LNG ke kapal shuttle tanker. penelitian ini melakukan identifikasi bahaya, penilaian risiko, mitigasi dan rekomendasi terhadap sistem transfer offloading kapal FLNG. Identifikasi bahaya menggunakan Hazard Identification (HAZID) dengan membagi sistem transfer untuk memudahkan proses identifikasi bahaya. Initiating event komponen diperoleh dari data process release frequencies untuk perhitungan Fault Tree Analysis (FTA) sedangkan data ignition probabilities digunakan untuk mendapatkan frekuensi kegagalan setiap skenario pada perhitungan Event Tree Analysis (ETA), kedua data tersebut berasal dari International Association Oil and Gas Producers (OGP) Standard. Analisa konsekuensi menggunakan fire modelling pada tiap skenario. Risiko akan direpresentasikan ke dalam f-N Curve yang mengacu pada UK HSE Standard. Analisa frekuensi dan konsekuensi dilakukan pada kebocoran 50 mm, 100 mm dan 200 mm pada skenario jetfire, gas dispersion, flash fire dan explosion, untuk mengetahui frekuensi (f) dan korban (N) pada setiap skenario. Pada skenario jetfire pada sub-sistem Storage & Loading kebocoran 50 mm berada pada area ALARP, dapat dilakukan mitigasi dengan mengurangi nilai frekuensi atau konsekuensi, atau menjaga nilai frekuensinya dengan perawatan berkala dan menggunakan komponen berkualitas agar risiko tidak naik ke area Intolerable. Sedangkan skenario lainnya berada pada daerah Acceptable, dimana kondisi risiko pada fasilitas offloading kapal FLNG dapat diterima. ======================================================================================================= Floating Liquefied Natural Gas (FLNG) is a floating structure which has main function as an LNG production, liquefaction, storage and offloading. The natural gas will be liquified at -160 oC and at pressure of 14.7 Psi until the volume decreased to 1/600 of its gas phase. FLNG requires cargo transfer process, in order to transfer the LNG from the FLNG storage tank to the cargo containment space of the shuttle tanker. This research has been conducted in a sequence of hazard identification, risk assessment, mitigation and recomendation of the LNG offloading transfer system. The hazard identification was carried out by HAZID method, in which the cargo offloading system was divided into several subsystem in order to simplify it. Initiating event for the components is obtained by means of analysis from the release process frequencies fault treen analiysis (FTA) calculation and ignition probablities used to get failure frequency to calculate event tree analysis (ETA) each scenario, both of data is derived based on the Standard Association Oil and Gas Producers (OGP). The consequence analysis was carried out by fire modelling of several leakage scenarios. The result of frequency and consequence analysis was then plotted in f-N Curve which refer to UK HSE Standart. Several simulations were conducted at a leakage scenario of 50 mm, 100 mm and 200 mm in the form of jetfire modelling. Gas dispersion, as well as flash fire and explosion, to know frequency (f) and casualty (N) for each scenario. This research found that the jetfire scenario in subsystem storage and offloading by leakage of 50 mm attained at As Low As Reasonably Practicable (ALARP) zone, and some mitigation efforts was then required by reducing the frequency or censequence or at least by maintaining the level of the frequency, for example: by conducting scheduled maintenance or using high quality component in order to prevent the risk not to shift to Intolerable Area. The other scenarios are eventually arrived at Acceptable zone, where the risk of the FLNG Ship offloading facility can be technically accepted

FUEL CONSUMPTION ANALYSIS ON THE PUTRA MAKMUR 86 VESSEL

The vessel's operation can run smoothly supported by reliable machines and can run effectively and efficiently. This reliability can be achieved through maintenance efforts, the right technology, and good fuel usage. Putra Makmur 86 vessel is one of the fishing vessels owned by PT. Matsyaraja Arnawa Satambhapura and operates in East Nusa Tenggara. This ship uses diesel fuel to support the performance of its engines. The use of this fuel is used to drive the main engine and two generators. Optimal use of fuel will of course have an impact technically and economically. The importance of the need for fuel on the ship's engine and the lack of information about the performance of the engines on the ship, so in this paper, an attempt is made to analyze the use of fuel and the performance of the main engine and generator during operation. The methods that were used in this study are observation, interviews, and analysis of fuel calculations are used in this study. Based on the results of operating activities for 32 days, the use of fuel on the Putra Makmur 86 Ship during its operation was very effective and efficient. Savings in the use of diesel fuel can be achieved by as much as 2.76% (0.21 Tons). This can be seen from the difference between direct observation and calculation of fuel consumption. The cause of this difference is the influence of good weather and currents during operation, shipping routes, engine conditions that are still good, payload, and good driving style so that fuel consumption is not too much
