|Abstract: ||The following proposal deals with a re-work of the raw water cooling system
onboard a U.S. Army Corps of Engineers vessel and the subsequent proposal to redesign,
build and install an improved cooling system.
The current cooling system onboard the M/V MISSISSIPPI receives raw river
water from inland waterways and is circulated through the main engines, reduction gears,
air conditioning system, the ballast, and fire main systems. Since the ship was built in
1992, the cooling system has experienced frequent clogging by debris and silt from
operations on the inland waterways. These cloggings cause system flow degradation,
subsequent failure of air conditioning condenser heat exchanger tubes and loss of
Our design project team proposes to design a replacement of the current system
with a closed loop system cooled by clean treated water. After implementing a cost
benefit analysis, we will provide documentation of all engineering analysis related to the
successful integration of the new system with the existing affected systems focusing on
mechanical, electrical and structural analysis.
During the second term of this project we plan to complete the detailed drawings
and analysis of the closed loop systems and test requirements. We will submit the
drawings to the United States Coast Guard (USCG) for approval and release to the
shipyard for installation. During that time, we also plan to take baseline measurements of
all affected systems and compare them with measurements after the installation to ensure
successful integration of our design.
Upon completion of testing and evaluation of the device, we will generate a final
report that will document our methods of analysis, results obtained and lessons learned.
We will then make recommendations for future design improvements, if needed.|
