PRELIMINARY DESIGN OF MULTI-PURPOSE SUPPLY VESSEL’S HULL STRUCTURE

Abstract

The Multipurpose Supply Vessel (MPSV) is an innovative vessel engineered to cater to a multitude of purposes. Its versatile design enables it to efficiently transport and supply cargo and personnel to offshore oil and gas installations. Additionally, the MPSV is equipped to undertake a diverse range of tasks, including subsea construction and maintenance, thereby enhancing its operational capabilities. The objective of this project is to ascertain an appropriate hull structure component that is compatible with the Multi-Purpose Support Vessel (MPSV). The structural compromise within the vessel's hull has the potential to result in more extensive and consequential damage. The occurrence of numerous ship hull failures throughout history has resulted in the unfortunate loss of hundreds of vessels. One prevalent issue encountered in hull structures pertains to the presence of structural design flaws (Vukelić, G., & Vizentin, G., 2017). To address this particular issue, it is recommended to make adjustments to the design of the scantling structural component by utilizing the ASTM A572 material. This material is chosen due to its remarkable strength-to-weight ratio, commendable resistance to corrosion, enhanced ductility, and exceptional weldability properties. The structural preliminary design methodology for a ship's hull structure entails a systematic approach aimed at ensuring the development of an optimal and efficient design. The parent hull serves the purpose of housing the hull form, specifically the MMA Pride with Monohull Structure. The analysis of A572 indicates that the utilization of this particular component in the MPSV effectively mitigates stress levels at the critical section. The outcomes of the conducted research play a pivotal role in fostering innovation and driving progress within the domain of MPSV (Multipurpose Support Vessel) design. Furthermore, the conducted research serves to enhance the comprehension of structural design principles that are particularly tailored to multi-purpose support vessels (MPSVs).
