Curved-Cylinder Crank-Rocker engine is a novel single-cylinder engine designed by Mechanical Engineering department of Universiti Teknologi Petronas, Malaysia. Heat dissipation on current cylinder block is very poor as the design of the fins are too thick(8mm) and have limited (3) number of pitches. So, the basis of this project is to design and analyses fins with better cooling effect for this innovative engine block. The design and analysis process in this project follows the knowledge of heat transfer in extended surface. Four conceptual designs have been created and from the four, one concept design was selected to be the final design. Steady-state thermal analysis has been done for each concept design developed. From the analysis, it found that length of fin gives huge effect toward temperature distribution. The selected design satisfies most of the selection criteria including required minimum temperature, mass and ease of manufacture. Finally, one prototype has been developed by using 3D printing method.

The maintenance cost for underwater facilities is very high. The cost might be significantly reduced by introducing API RP 584 or “integrity operating window (IOW)” program. However, successful construction and deployment of IOW requires identification of working limits for each piece of equipment and a comprehensive platform for monitoring of operational boundaries. If well designed, IOW provides alerts, notifications, analysis and decision support. Recording of actions following alert notifications are also possible. This will later be used to predict ahead the likelihood of safety critical conditions.

Automation System for a sub-assembly machine using a collaborative robot arm (Universal Robot). The basis of this project is to do an integration of an automation system to a sub-assembly machine. This machine is used to assemble one of the sub-assembly part for a brake sensor. This machine used to be operate by production operator to perform part placement in the machine along with visual inspection. Process automation done towards this machine is by integrating a collaborative robot arm with bowl feeder, linear feeder, and rotary cylinder. Overall approach of this project is to take over repetitive tasks and free up man power to perform more rewarding tasks as well as improving process productivity.
