Abstract:

The objective of this thesis is to attempt to reconcile Military Sealift Commands MSC and Defense Fuel Supply Centers DFSC different points of view with respect to tank cleaning on tankers in government service. Currently, petroleum tankers in government service have extensive requirements to clean and gas-free cargo tanks prior to loading other petroleum products. However, to save money and avoid disposal complications, the MSC periodically requests waivers from the DFSC to not clean and gas-free cargo tanks. These waivers are usually requested when the last product carried may be compatible with the next product to be loaded. DFSC infrequently grants these waivers primarily due to quality concerns and liability issues. MSCs and DFSCS perspectives are presented and then compared to Chevron Shipping Companys CSC operations. The practices of government and commercial tanker operations are compared and analyzed. Finally, conclusion and recommendations are presented. Slops, Gas-free waiver requests.
