Applications Experience

LNG Carriers

LNG carriers play a critical role in the LNG supply chain, sustaining the global energy life line. Leading LNG transportation companies keep their carriers in top condition to ensure safe voyages throughout the entire duration of a supply contract. Due to the complexities of controlling both machinery and cargo over the more than 20 year life time of the typical LNG carrier, forward-looking transporters are introducing innovative technologies that improve voyage efficiency, minimize carrier downtime, and improve cost competitiveness. This exemplifies VigilantPlant®, a Yokogawa concept providing a clear path to operational excellence. Learn how a vigilant approach to LNG transportation can help leading companies achieve operational excellence by staying alert, predictive, and responsive.

47 carriers use a Yokogawa DCS.
