Boil Off Gas (BOG) merupakan gas yang terbentuk karena adanya panas yang masuk (heat leak) kedalam tangki Liquefied Natural Gas (LNG). Evaporasi yang terjadi secara terus menerus dapat meningkatkan tekanan pada tangki, menyebabkan tekanan berlebih yang berbahaya. BOG tersebut harus dimanfaatkan atau dibuang melalui proses pembakaran untuk menjaga tekanan tangki muatan. BOG yang dibuang merupakan sebuah kerugian bagi perusahaan. Pada FSRU ini memiliki nilai rata – rata BOG perharinya sebesar 92.714,936 m³n Gas dan boil off rate 0,237%. Pemanfaatan BOG pada FSRU digunakan untuk bahan bakar generator DFDE dan boiler dengan nilai rata – rata perharinya 837,363 MMBTU, sehingga memiliki nilai BOG berlebih rata – rata perharinya 2.823,184 MMBTU. Metode pemanfaatan BOG berlebih dengan melakukan reliquefaction, atau langsung menyalurkannya ke linepack offshore pipeline menggunakan MSO compressor. Dalam pemilihannya, menggunakan reliquefaction plant Wartsila HGS Mark III, menggunakan siklus kerja inverse brayton, berkapasitas 7.000 kg/h. Sedangkan untuk MSO compressor menggunakan BOG kompresor Burckhard Laby GI Compressor LP250 4 stages, kapasitas 10.000 kg/h. Berdasarkan aspek ekonomis penggunaan MSO compressor memiliki nilai CAPEX dan OPEX lebih rendah, tetapi secara nilai NPV, IRR dan PP penggunaan reliquefaction plant memiliki nilai lebih baik. Sedangkan berdasarkan kondisi operasional FSRU, reliquefaction plant lebih cocok secara teknis untuk digunakan.

One of the phenomenon appears on operation of marine propeller is noise. It could reduce performance of the propeller. In this study, numerical simulation is used to predict hydrodynamic performance and noise around non cavitation propellers. The formulation of RANS (Reynold Averaged Naiver Stokes) with turbulence model k-ω SST (Shear Stress Transport) and FWH (Ffowcs Williams–Hawkings formulation) is applied on the simulation. The noise is expressed in time-domain acoustic analogy as well as finite volume, and it is predicted at different receiver positions. The performance of propeller is predicted by MRF technique (Multiple Reference Frame). The 3D model of B-series propeller with diameter of D = 250 mm, blade number Z = 4, pitch diameter ratio P/D = 1, and area ratio Ae/Ao = 0.55 is simulated on various advance coefficients (J). Propeller rotation is simulated in range of 7.5 rps - 29rps and Re = 6.95x104– 3.36x106

This paper examines the risk to subsea gas pipeline during hot-tapping installation process. Hot tapping is one method to connect new pipeline to existing pipeline while they remain in service. In this study it is considered that hot tapping is installed using crane barge. To assure the crane barge in steady position, the crane barge is moored by means of mooring chain at several locations. These mooring activities and hot tapping installation possess potential risk to existing subsea facilities. Hence, in general there are two objectives in this study such as: determining the safe distance between mooring chain for and the existing facilities, and performing risk level due to external load that may occurs during installation. The risk level is determined by analyzing frequency and its consequence then will be mapped into risk matrix according to DNV-RP-F107. From mooring distance analysis, the result can be used as a reference for positioning the mooring point of crane barge. Based on the result of risk assessment to facilities, risks due to external load such as dropped anchor, dragged anchor, ship sinking and dropped object are in the as low as reasonably practicable (ALARP) region which mean, in the practical life risks are acceptable as long as the frequency is maintained in the lowest rank.
