海洋垃圾是一個尚未解決的全球性問題，這促進了海洋垃圾清潔技術的出現。本研究對防止和收集塑料污染的技術進行了審查，結果顯示，海洋垃圾清潔技術被歸類為專注於海洋污染防治的技術和收集技術，其中之一是傳送船。然而，尚未研究輸送機在收集廢物方面的效率。在前人的研究上大多應用於湍急水流和波浪的地方，而在沒有水流和波浪的地方，例如湖泊、靜止的河流和其他平靜的水域，並沒有過多論述。本研究提出了一種收集海洋垃圾的船舶及系統，其中結合了船、輸送機和機翼。輸送機功能為將海面的海洋垃圾裝載到船上，而機翼則用於增加輸送機收集海洋垃圾的能力。
本研究設計了實驗研究，以研究機翼輸送機在海洋垃圾收集中的有效性。在研究中使用該模型的幾種變體進行了實驗，即帶無翼輸送機的雙體船、使用實心翼的帶輸送機的雙體船和使用空心翼的帶輸送機的雙體船。每個模型都被設計成模型變體，以觀察對輸送機在海洋垃圾收集中的有效性。然後再對當前研究進行數值模擬，以研究輸送機、船舶及其環境之間的阻力、速度等值線和流動模式等流體動力學特性，並研究機翼輸送機在海洋垃圾收集中的效率。在數值模擬方面，海洋垃圾接近傳送帶的難易程度以及其流型特徵、速度等值線等是本研究專注重點。其中，速度等值線用於分析海洋廢物接近輸送機的速度，而阻力分析則用於了解能源消耗的影響。接下來，使用其他研究的實驗模型對數值模擬過程進行驗證。此外，還提出了可持續海洋垃圾管理數字平台的商業模式，以支持海洋垃圾清理。

Marine debris is a global problem that has not been resolved. This has encouraged the emergence of marine debris cleaning technologies. A review of technologies to prevent and collect plastic pollution has been carried out. The results showed technologies were categorized as technologies focusing on marine pollution prevention, and collection technologies, one of which is a conveyor ship. However, how effective conveyors are in collecting waste has not been studied. These previous studies also can only be applied in locations that have large currents and waves; the idea is not applicable to locations without currents and waves such as lakes, sedentary rivers, and other calm waters. This thesis proposed a ship and system for collecting marine debris. It combines ship, conveyor, and wing for their system. The conveyor is used to load the marine debris from the sea surface into the ship. Then the wing is used to increase the conveyor capability to collect marine debris.
Experimental study was conducted to investigate the wing conveyors' effectiveness in marine debris collecting. Experiments were carried out using several variations of the model, namely catamarans with conveyors without wings, catamarans with conveyor using solid wings, and catamarans with conveyor using hollow wings. Each model is made into several model variations to determine the effect on the conveyors' effectiveness in marine debris collecting. Then, numerical simulation of the current research was conducted to investigate hydrodynamics characteristics such as resistance, velocity contour, and flow patterns between conveyors, ships, and their environment, as well as to investigate the wing conveyors' effectiveness in marine debris collecting. The flow pattern characteristics that are used to analyze how easy it is for waste to approach the conveyor, velocity contour which is used to analyze how fast the ocean waste is approaching the conveyor, and resistance which will affect energy consumption. Next, validation of the numerical simulation process is carried out with experimental models from other studies. Furthermore, a business model of digital platform for sustainable marine debris management is also proposed to support marine debris cleaning.
