Analysis of Monohull Design Characteristics as Supporting Vessel for the COVID-19 Medical Treatment and Logistic

Abstract

The world is being hit by a health crisis by the COVID-19 pandemic which has infected peoples across the globe. The cases of COVID-19 in Indonesia itself continue to increase every day. The transportation sector is one of the sectors that have experienced numbers of direct impacts as a result of large-scale social restriction in form of preventive regulation. Furthermore, this phenomenon causes health agencies to experience difficulties in distributing logistics for handling COVID-19, especially in water areas. In the era of the Industrial Revolution 4.0, various society aspects and industrial processes are digitally connected to increase productivity, especially for COVID-19 treatment and logistic handling. This research was conducted to analyze several proposed monohull-unmanned ship prototypes which are expected to be a proposed solution to assist COVID-19 countermeasure. A series of stability and motion analyses is conducted, then the results are assessed to conclude the best design among the proposed design options. Results of the study indicated that compared to three variations of hull types, design of the Model III has excellent characterisics of ship stability, hull resistance and seakeeping. These analysis parameters are considered as main criteria in the ship’s requirements since patient and logistic have to be transported safely to the designated location according to the given mission in assisting COVID-19 handling and treatment.

Fast ship prototype design simulation with fin stabilizer on hydrodynamic characteristics for ship realization planning

“…One of the methods that can be used in ship design is the comparison method, in which a sailing ship is used as a reference for designing and developing [11]. The ship data using reference ships designed by the company is based on experts in the maritime industry [12].…”

“…Seakeeping theory studies the motion of surface vessels in waves [23]. Seakeeping analysis is a procedure for computing vessel performance metrics related to the envelope of missions and environmental conditions in which the vessel is to operate [11]. Seakeeping tests get response amplitude operator (RAO) graphs to consist of heave motion and roll motion.…”

Effect of bilge keel variations on the designed fast patrol boats to hull resistance and stability behaviours

“…Stability testing is the ship's ability to be upright again after experiencing a certain roll/tilt [15][16][17]. In general, stability is divided into static stability (Equation 2) and dynamic stability (Equation 3).…”

Analysis of hull performance on fast patrol boat with an extended study of survivability under damaged conditions

“…When the equilibrium state is stable, the center of buoyancy and gravity are in one direction, and the longitudinal and transverse lines are aligned with the trim angle. Flooding on the ship will also affect the trim angle, dynamic stability, roll period, and pitch period, and these factors contribute significantly to the ship's sinking [9][10][11][12][13].…”
