StormGeos Seaware product adds GTTs tank sloshing prediction and alerting system
StormGeo has partnered with French company GTT to add enhanced Liquid Natural Gas (LNG) membrane tank sloshing prediction and monitoring to their current Seaware EnRoute Live (ERL) on-board software product.
GTT engineered membrane containment LNG cargo tank
LNG shippers who use this product will benefit fromSeawareseakeeping operational decision support that incorporates components of ship motion, stability, weather, and sea state. This well-proven vessel monitoring complements GTT’s industry leading expertise in the design and development of cargo tank systems for LNG carriers.
Sloshing in tanks is one operational factor to be considered for all LNG carrier owners or operators. Due to its stochastic nature, sloshing can generate impacts on the containment system, for which zero risk cannot be attained, even in moderate sea states.

Furthermore, sloshing is also identified as a first order factor for the increase in natural boil off of the liquid cargo. Managing the risk of sloshing is then a critical economical concern for all the actors of maritime LNG transport.
To avoid an excessive tank sloshing incident at sea, thisSeaware on-board system with GTT’sSloshing Prediction Program takes into account the detailed hull lines of the ship, the actual loading condition, roll damping, wave spectrum, and ship speed/heading.
The captain can, prior to departure, simulate and plan a sailing route mitigating potential tank sloshing risks as part of a safe and efficientSeaware calculated optimized route recommendation.
As loading condition, weather, and sea state conditions can change during transit,Seaware’s ERL uses its tactical alerting mode to alert the Captain and bridge officers for potential excessive tank sloshing risk with enough time to change course or speed and to provide guidance in choosing the most efficient mitigation action.
