K-Sim® Cargo LNG tanker - Spherical - KONGSBERG DIGITAL

K-Sim® Cargo LNG tanker Spherical Operators of LNG tankers must be familiar with process-controlled operations to maintain control at the start of loading and discharging. If the cargo boils off too fast or the tank is cooled down too fast, pressure or vacuum can lead to extreme temperatures damaging the tanks or the hull structureLPG and LNG spherical tank - level, pressure | VEGALPG tanks are usually only accessible for service and maintenance work every few years during shut-down periods. In addition, the containers are mostly installed underground or covered with earth. The solution is a process independent measuring system that delivers safe and reliable readings despite low dielectric constants and low temperatures.
