Abstract

Oil spill incidents can bring adverse effects to both human and aquatic life as well as the environment if there is not any efficient action taken to resolve the problem. Conventional ways of controlling the oil spillages which are using barriers and absorbent materials to recover the spilled oil mechanically. An earlier prototype of Portable Oil Spill Skimmer has been developed to compliment the recovery of oil spills of the existing methods but encounters limitations on the mechanical components during operation. This project emphasizes on the enhancement of the Portable Oil Spill Skimmer in terms of its mechanical performance for better seakeeping ability and maneuverability in the open water during oil spill response and recovery activities. The enhancement includes the selection of material suitable for the application in different areas such as sea, river and area subjected to oil spill. Stress-Strain and Computational Fluid Dynamics (CFD) analyses are employed to review the design of the existing prototype and make changes to optimize the underperformed area of the model like the frame, hull and thruster. 3D models of frame, hull and thruster are produced by using solid modelling software like SOLIDWORKS. After performing the stress-strain simulation, the results show that the designed aluminium frame is able to sustain the heavy loading of the various components of Portable Oil Spill Skimmer. Also, the CFD simulations are used to determine the drag and thrust force of the hull and thruster so that the results can be used to make decisions and justifications on the proposed parts. In conclusion, the enhancements proposed onto the Portable Oil Spill Skimmer to improve the robustness and maneuverability could help in the durability and efficiency of the system during oil recovery operations.
