A joint industry project managed by the Norwegian classification society Det Norske Veritas (DNV) is presenting valuable findings on the technology of LNG cargo tanks.
Since 2008, BW Imo has participated in a study on sloshing impact forces in LNG membrane tanks. A new method of measuring these forces was introduced this year, whereby pressure sensors are pre-installed in the cargo tank. Measuring liquid sloshing is particularly important for avoiding damage to internal insulation systems of LNG carriers.
The next step will be to study the measured impact forces and their correlation with external factors such as weather, wave condition, loading condition and tank filling height. The study is expected to lead to an advanced decision support system for smarter ship operations.
