Abstract

Transisi energi di sektor pelayaran mendorong penggunaan Liquefied Natural Gas (LNG) sebagai bahan bakar alternatif yang lebih ramah lingkungan dibandingkan bahan bakar minyak konvensional karena mampu menghasilkan emisi CO₂, NOₓ, dan SOₓ yang lebih rendah. Salah satu penerapan teknologi tersebut adalah penggunaan removable LNG ISO tank pada kapal kontainer berbahan bakar LNG, dimana proses suplai bahan bakar dilakukan melalui pergantian LNG ISO tank secara langsung. Sistem ini memiliki rangkaian peralatan yang kompleks, seperti vaporizer, cryogenic valve, gas line, dan sistem kontrol, sehingga membutuhkan strategi perawatan yang tepat untuk menjaga keselamatan dan keandalan operasional kapal. Kegagalan pada komponen sistem bahan bakar LNG dapat menyebabkan gangguan operasi, kehilangan daya propulsi, hingga potensi bahaya terhadap keselamatan dan lingkungan. Penelitian ini bertujuan untuk mengidentifikasi tingkat konsekuensi komponen dan menyusun strategi perawatan pada sistem bahan bakar LNG kapal kontainer secara sistematis. Penelitian dilakukan dengan menggunakan data Process and Instrumentation Diagram (P&ID) sebagai dasar penyusunan asset register, kemudian dilanjutkan dengan pembentukan technical hierarchy dan functional hierarchy untuk mengelompokkan sistem dan peralatan berdasarkan fungsi operasionalnya. Selanjutnya dilakukan analisis konsekuensi kegagalan menggunakan consequence class berdasarkan standar NORSOK Z-008 untuk menentukan tingkat kekonsekuensian masing-masing komponen. Hasil identifikasi tingkat konsekuensi komponen tersebut digunakan sebagai dasar dalam penyusunan strategi maintenance yang sesuai dengan tingkat risiko dan kebutuhan operasional sistem. Pendekatan ini diharapkan dapat menghasilkan strategi perawatan yang lebih efektif, terstruktur, dan berbasis konsekuensi sehingga mampu meningkatkan keselamatan, keandalan, dan efisiensi operasional kapal berbahan bakar LNG. Selain itu, penelitian ini diharapkan dapat menjadi referensi dalam pengembangan sistem manajemen perawatan untuk sistem bahan bakar gas alam di sektor maritim.

The energy transition in the maritime sector has encouraged the use of Liquefied Natural Gas (LNG) as an alternative fuel that is more environmentally friendly than conventional fuel oil due to its lower emissions of CO₂, NOₓ, and SOₓ. One implementation of this technology is the use of removable LNG ISO tanks on LNG-fueled container vessels, where the fuel supply process is carried out through direct replacement of LNG ISO tanks. This system consists of complex equipment arrangements, such as vaporizers, cryogenic valves, gas lines, and control systems, which require appropriate maintenance strategies to ensure operational safety and reliability. Failure of components within the LNG fuel system may result in operational disruptions, loss of propulsion power, and potential hazards to safety and the environment. This study aims to identify component consequences and develop maintenance strategies for the LNG fuel system of a container vessel in a systematic manner. The study was conducted using Process and Instrumentation Diagram (P&ID) data as the basis for developing the asset register, followed by the establishment of technical hierarchy and functional hierarchy to classify systems and equipment based on their operational functions. Subsequently, a consequence analysis was carried out using consequence classes based on the NORSOK Z-008 standard to determine the criticality level of each component. The identified component consequences were then used as the basis for developing maintenance strategies aligned with the risk level and operational requirements of the system. This approach is expected to produce a more effective, structured, and consequence-based maintenance strategy, thereby improving the safety, reliability, and operational efficiency of LNG-fueled container vessels. Furthermore, this study is expected to serve as a reference for the development of maintenance management systems for natural gas fuel systems in the maritime sector.
