Summary of My Responsibilities

I enjoyed a rewarding engineering career with Samsung Techwin, and contributed to the design engineering of six integrally geared centrifugal compressors for air separation, aviation testing and LNG applications. 

For the air separation industry, we designed the nitrogen recycle compressor and the main air compressor. 


For the LNG industry, we designed the boil-off gas compressors used to recover the unavoidable boil-off gas from the cargo tanks on LNG ships during voyage. Natural Gas has a very low energy density. The volume of Natural Gas in its liquid state is 600 times smaller than its volume in its gaseous state. Therefore, in order to be used efficiently as an energy source it needs to have its density increased by cooling it to cryogenic temperatures, which creates Liquified Natural Gas (LNG). On LNG carrier ships, this LNG is stored in well-insulated tanks in its liquid state. However, the heat transfer that occurs with the surroundings will cause some of this LNG to evaporate and become boil-off gas. Thus, this boil-off gas must be removed from the tanks to prevent excessive pressure build up.

Our team worked with the engineers in South Korea to design a complete HD and LD package within the typical constraints of a LNG ship's compressor room. I traveled to South Korea and visited the Samsung Techwin headquarters and Vendors in order to assist during initial assembly of the LD compressor.

Below is a quick summary of what my daily job entailed:

• Contributed to the creation of all the necessary 3D models and engineering drawings with accuracy, and careful consideration for the ease of assembly and industry standards 
• Developed an organized work schedule in order to work in a fast-paced, multi-project and multi-cultural environment 
• Reduced revisions for the design team by customizing parameterized models and drawings to avoid costly mistakes 
• Cultivated my personal design knowledge by studying GD&T, compressors and continually asking for more complex parts to be responsible for 
• Built rapport with overseas colleagues, and had the privilege of traveling to South Korea for assembly support.
