In February 2023, Svanehøj Tank Control Systems will deliver the tank gauging system for COOEC’s six new LNG tanks for the Longkou Nanshan LNG Terminal which is under construction. It is being built as the global trade of LNG is spiking.
Global investments in LNG are increasing, not least in China, who is currently constructing around 40 LNG tanks with the capacity of 220.000 m3. To secure the LNG storage, one of the largest EPCI contractors for offshore oil and gas industry in the Asia Pacific region, COOEC, has chosen Svanehøj Tank Control Systems to implement tank gauging system to improve safety on six new LNG tanks of 220,000 m3.
One consequence of increased global trade in LNG is an increased diversification of LNG supply sources. The import terminals must increasingly handle LNG with different compositions, which is a primary concern in terms of assuring stability and safety in LNG storage. It can be an unstable stratification that can evolve into a rollover of the layers. This causes an increase in the boil off rate up to 10 times than the normal condition, increase or over pressurization of the tank, or lifting of relief valve of the tanks, explains David Clercq, Sales Manager at Svanehøj Tank Control Systems.
The monitoring systems are important to keep the highest safety measures on the LNG-import terminals. The servo level gauges will be providing continuous measurement of the LNG level using a servo-driven sensor that is in direct contact with the liquid. Thereby, ensuring that the levels inside the LNG-storage are stable. The LTD gauges will simultaneously provide accurate
