Abstract

Penelitian ini menganalisis kelayakan teknis penerapan Magnetic Drive Pump (MDP) pada sistem deepwell pump kapal IMO Type 2 chemical tanker untuk transfer bahan kimia korosif. Evaluasi dilakukan terhadap konfigurasi deepwell dengan magnetic coupling di sisi deck sebagai pengganti mechanical seal konvensional. Analisis meliputi studi literatur, pemodelan hidraulik, perhitungan Total Dynamic Head (TDH), validasi menggunakan PIPEFLOW Expert, evaluasi performa pompa, kompatibilitas material terhadap H₂SO₄ 98%, NaOH 50%, dan H₃PO₄ 85%, serta perbandingan kebutuhan daya, efisiensi, dan aspek pemeliharaan. Hasil menunjukkan bahwa konfigurasi deepwell magnetically coupled secara teknis layak diterapkan pada kondisi operasi dengan tekanan terminal hingga 3 bar, memberikan containment yang lebih baik melalui eliminasi mechanical seal serta menurunkan potensi kebocoran. Walaupun terdapat penalti efisiensi akibat rugi-rugi magnetik dan biaya awal yang lebih tinggi, peningkatan keandalan, keselamatan, dan pengurangan kebutuhan perawatan menjadikan sistem ini layak dipertimbangkan untuk aplikasi kapal chemical tanker IMO Type 2.
Hasil yang diharapkan dari penelitian ini adalah diperolehnya evaluasi komprehensif mengenai kesesuaian teknis MDP terhadap kebutuhan operasional sistem auxiliary kapal chemical tanker, termasuk kemampuan dalam mengurangi risiko kebocoran, meningkatkan reliabilitas containment, serta implikasi terhadap efisiensi energi dan kebutuhan perawatan. Penelitian ini juga mengidentifikasi keterbatasan teknis dan batasan operasional MDP sebagai dasar rekomendasi rekayasa untuk implementasi pada kapal IMO Type 2.

This study evaluates the technical feasibility of applying a magnetic-drive deepwell pump to an IMO Type 2 chemical tanker handling corrosive chemicals. The proposed configuration replaces the conventional deck-mounted mechanical seal with a magnetic coupling while retaining the proven deepwell architecture. The assessment combines literature review, hydraulic modelling, Total Dynamic Head calculations, PIPEFLOW Expert validation, pump performance evaluation, material compatibility assessment for 98% sulfuric acid, 50% sodium hydroxide, and 85% phosphoric acid, and comparison of power demand, efficiency, and maintenance characteristics. The results indicate that the proposed arrangement is technically feasible under operating conditions including a terminal back pressure of up to 3 bar. Although magnetic drive technology introduces additional magnetic losses and higher initial cost, it significantly improves containment integrity by eliminating the dynamic shaft seal, reducing leakage risk and maintenance requirements while enhancing operational safety for IMO Type 2 chemical tankers.
The expected outcomes of this research include a comprehensive technical evaluation of MDP suitability for auxiliary chemical transfer operations, assessment of their potential to reduce leakage risk and improve containment reliability, and analysis of operational reliability and energy performance. The study also identifies technical limitations and operational constraints to provide engineering recommendations for the appropriate implementation of Magnetic Drive Pumps in IMO Type 2 chemical tankers.
