Weather-related economics of natural gas transport for two propulsion plant configurations

It has always been difficult to incorporate the effect of environmental conditions into an economical evaluation. This study shows that scenario simulations can be a valuable tool to get an idea about the uncertainties concerning power demand and roundtrip duration due to wind, waves and current. This paper presents the procedure and results of an economical evaluation of an LNG carrier with two different propulsion plant configurations. The evaluation is firstly performed without weather influences. Subsequently, the weather influences are incorporated by using scenario simulations.
