COST-BENEFIT ANALYSIS OF CONVERTING WASP CLASS LANDING HELICOPTER DOCK (LHD) STEAM PROPULSION PLANTS TO HYBRID PROPULSION

The purpose of this thesis is to conduct a cost-benefit analysis of converting steam-powered propulsion plants on-board Wasp-Class Landing Helicopter Dock (LHD) hulls 1 through 7 to hybrid propulsion. The objective of this research was to evaluate the net present value of conversion by weighing the cost-savings benefits of fuel savings, in-port utility consumption, and manpower against the cost of conversion. The results of the analysis conclude that LHDs 5 and 7 have a positive net present value; therefore, their conversion is recommended. LHD 6 can have a positive net present value with recommended complex overhaul schedule changes. Recommendations are made to maximize benefits to the Navy, considering potential changes in force structure and follow-on studies.
