Abstract
The implementation of dual-fuel engines as the main propulsion of ships in Indonesia is still low. It is necessary to study the ship design process for ships with dual fuel engines, especially for engine rooms. Process and instrumentation diagrams as two-dimensional drawings cannot provide an overall illustration of the actual engine room. The overall illustration of the actual engine room is well obtained using the three-dimensional design. First, this research is to find out the process and instrumentation diagrams on the harbor tug diesel-LNG dual fuel engine 2 × 2500 HP. Second, this research is to find out the original, clustered, and reordered design structure matrix of all piping components. Third, this study aims to determine the three-dimensional design using modularization with a rule-based algorithm. The components of the bilge & ballast system, oily water separator system, fire suppression system, domestic supply and exhaust system, marine diesel oil system, LNG fuel system, lubricating oil system, cooling system, and compressed air system are incorporated into the DSM to become the original DSM. Rule based algorithms are for clustering and reordering. At the end of the original, clustered, and reordered DSM composing, it is necessary to calculate the sum and objective function value. The clustering algorithm feature in the DSM modeler used already includes clustering and reordering algorithm. The reordering process is carried out manually to ensure that the reordered DSM already has a sequence that is in accordance with the work process sequence of the piping system. Comparison of sum and objective function value of clustered and reordered DSM always gives a smaller value than the original DSM. Meanwhile, the objective function and sum in clustered and reordered DSM have the same value. The reordered DSM which has the smallest sum and objective function values will be used as the basis for making three-dimensional design. Process and instrumentation diagrams will provide an overview of the required components. The number and types of components in the process and instrumentation diagrams are adjusted to the rules of the Indonesian Classification Bureau (BKI). Reordered DSM will simplify the process of laying components in the engine room. The components of the piping system that are included in one cluster need to be located close together. Moving components that are included in one cluster means having to move all the components contained in that cluster. Modularization with a rule-based algorithm can be applied to the three-dimensional design of the engine room layout. ==================================================================================================
Implementasi mesin berbahan bakar ganda sebagai penggerak utama kapal di Indonesia masih rendah. Perlu adanya kajian tentang proses desain kapal untuk kapal bermesin bahan bakar ganda khususnya untuk kamar mesin. Diagram proses dan instrumentasi sebagai gambar dua dimensi tidak dapat memberikan gambaran keseluruhan dari kamar mesin yang sebenarnya. Gambaran keseluruhan dari kamar mesin yang sebenarnya diperoleh dengan baik menggunakan desain tiga dimensi. Pertama, penelitian ini untuk mengetahui diagram proses dan instrumentasi pada mesin harbour tug diesel-LNG dual fuel engine 2 × 2500 HP. Kedua, penelitian ini untuk mengetahui matriks struktur desain original, clustered, dan reordered dari semua komponen perpipaan. Ketiga, penelitian ini untuk mengetahui desain tiga dimensi menggunakan modularisasi dengan algoritma berbasis aturan. Komponen dari sistem bilge & ballast, sistem separator air berminyak, sistem pemadam kebakaran, sistem pasokan dan pembuangan domestik, sistem minyak solar laut, sistem bahan bakar LNG, sistem minyak pelumas, sistem pendingin, dan sistem udara tekan dimasukkan ke dalam DSM menjadi original DSM. Algoritma berbasis aturan adalah untuk pengelompokan dan penataan ulang. Pada setiap penyusunan original, clustered, dan reordered DSM perlu dilakukan perhitungan sum dan objective function. Fitur algoritma clustering pada DSM modeler yang digunakan sudah mencakup algoritma clustering dan reordering. Proses penataan ulang dilakukan secara manual untuk memastikan reordered DSM sudah memiliki urutan yang seusai dengan urutan proses kerja dari sistem perpipaan. Perbandingan objective function dan sum value dari clustered dan reordered DSM selalu memberikan nilai yang lebih kecil dari original DSM. Sedangkan untuk objective function dan sum pada clustered dan reordered DSM memiliki nilai yang sama. Reordered DSM yang memiliki nilai objective function dan sum paling kecil akan digunakan sebagai dasar pembuatan desain tiga dimensi. Diagram proses dan instrumentasi akan memberikan gambaran komponen yang dibutuhkan. Jumlah dan macam komponen pada diagram proses dan instrumentasi disesuaikan dengan aturan dari Biro Klasifikasi Indonesia (BKI). Reordered DSM akan mempermudah dalam proses peletakan komponen pada kamar mesin. Komponen sistem perpipaan yang termasuk dalam satu cluster perlu ditempatkan secara berdekatan. Pemindahan komponen yang termasuk dalam satu cluster berarti harus memindahkan seluruh komponen yang terdapat dalam cluster tersebut. Modularisasi dengan algoritma berbasis aturan dapat diterapkan pada desain tiga dimensi tata letak kamar mesin.
