Since the beginning of the 21st century, LNG has been very much in the picture. Oil majors are expecting that LNG will be taking a much larger share in the energy mix in the next 25 years. The LNG value chain necessarily involves LNG shipping. It's in this part of the value chain that we've seen some major technology changes recently. The introduction of the dual fuel diesel electric (DFDE) LNG carrier (LNGC) and the slow speed diesel driven LNGC with onboard reliquefaction (DRL) are radical departures from the currently dominant steam turbine drive technology. The introduction of the dual fuel diesel electric drive systems could also open the door for dual fuel gas turbine electric (DFGTE) propulsion systems, as they are based on the same electric drive concept.

The very fact that gas turbines are used in mission critical applications all throughout the LNG value chain is testament to their reliability. However, there are a few, very persistent misconceptions about gas turbine drive systems. Many of these misconceptions actually date back to the early 1970's when the first gas turbine driven LNGC was introduced. Indeed the gas turbine drive system onboard GTS "Lucian" never lived up to expectations. Now more than 30 years later, gas turbine manufacturers are promoting gas turbine drive systems again. This paper will examine the gas turbine drive system onboard GTS "Lucian" and identify a number of differences with the latest DFGTE drive systems proposed for LNGC propulsion.
