"We can replace control system without interrupting city gas production."
Yokogawa has more than 30 years of experience in executing LNG projects, and has acquired significant engineering know-how. We know how to replace control systems without interrupting city gas production. We can ensure a seamless migration path and supply a full range of implementation services.
"Once you bring a tank down to the right temperature, it stays there."
The temperature inside an LNG tank is kept at a constant -162°C. If there is a long interruption in gas production and enough LNG is lost as boil-off gas (BOG), the temperature inside the tank will begin to rise, this will eventually "hot-up" to the ambient temperature and the tank will have to undergo an expensive, time-consuming initialization process to cool it down again to -162°C. Tanks remain in use for 50-60 years. On the other hand, control systems have a relatively much shorter lifecycle. Assuming a lifecycle of 20 years, the control system will need to be replaced at least twice. We have a great deal of experience doing hot cutover replacement of DCSs. Once we bring a tank down to the right temperature, it stays there.
