Abstract

Dunia perkapalan terus berkembang pesat demi menghasilkan desain kapal yang paling efisien termasuk desain kapal tanker. PT Pertamina selaku perusahaan minyak dan gas terbesar di Indonesia memiliki 69 kapal tanker berukuran ≥ 150 m atau sekitar 42% dari total armada kapal tankernya. Berdasarkan regulasi MARPOL 73/78, Common Structural Rules, dan PM No. 29 Tahun 2014 semua kapal tanker berukuran di atas 5,000 DWT wajib dilengkapi dengan struktur double bottom, double side, dan hopper pada bilge area. Struktur tersebut dibuat demi keselamatan lingkungan, namun struktur tersebut menyebabkan pengurangan volume ruang muat. Oleh karena itu, struktur tersebut perlu dioptimalkan agar diperoleh volume ruang muat yang maksimal. Terdapat beberapa metode yang dapat digunakan untuk menemukan solusi yang optimal dari permasalahan tersebut salah satunya adalah menggunakan metode grid search. Pemrograman bahasa Visual Basic for Application akan digunakan untuk mempercepat proses optimisasi. Selanjutnya, hasil pemrograman ini akan diintegrasikan dengan software Maxsurf untuk melihat secara langsung bagaimana pengaruh perubahan pada desain kapal terhadap stabilitas dan kekuatan memanjang kapal. Desain hasil optimisasi memiliki desain freeboard, stabilitas, dan kekuatan memanjang yang masih memenuhi regulasi yang berlaku. Desain hasil optimisasi menunjukkan peningkatan volume ruang muat sebesar 0.960% dengan perkiraan peningkatan omzet mencapai Rp 6.2 miliar.

The world of shipping continues to develop to produce the most efficient ship designs, including tanker ship designs. As the largest oil and gas company in Indonesia, PT Pertamina has 69 tankers measuring ≥ 150 m or around 42% of its total tanker fleet. Based on MARPOL regulations 73/78, Common Structural Rules, and PM No. 29 Tahun 2014, all tankers measuring over 5,000 DWT must be constructed with double bottom, double side and hopper in the bilge area. These structures are constructed for environmental safety, but on the other hand, they cause a reduction in the cargo volume. Therefore, those structures need to be optimized to obtain maximum cargo volume. Several methods can be used to find the optimal solution to this problem, one of which is the grid interval search method. The Visual Basic for Application programming language will be used to enhance the optimization process. Furthermore, the results of this programming will be integrated with Maxsurf software to show directly how changes to the ship design affect ship stability and longitudinal strength. Optimized-design still complies with the regulation of freeboard, stability, and longitudinal strength. Optimized-design shows an increase of cargo hold volume by 0.960% with Rp 6.2 billion turnover.
