GTT partners with StormGeo

Published by
LNG Industry,

StormGeo has partnered with GTT to add enhanced liquefied natural gas (LNG) membrane tank sloshing prediction and monitoring to its current Seaware EnRoute Live (ERL) on-board software product. 

LNG shippers stand to benefit from Seaware operational decision support that incorporates components of ship motion, stability, weather, and sea state. This vessel monitoring complements GTT’s expertise in the design and development of cargo tank systems for LNG carriers. 

For LNG carrier owners or operators, sloshing in tanks is an important factor to consider. To avoid an excessive tank sloshing incident at sea, this Seaware on-board system with GTT’s Sloshing 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 efficient Seaware calculated optimised route recommendation.

As loading conditions, 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.

Based on GTT’s expertise on statistical sloshing data analysis and Seaware ERL monitoring/recording capacities, post voyage analysis can also be performed, enabling improvement of fleet management.

Kent Zehetner, CEO of StormGeo, said: “The addition of the sloshing prediction program will add significant value for our LNG clients by improving safety during the voyage. We measure success through the number of risks we enable our clients to avoid.”

Philippe Berterottière, CEO of GTT added: “Our expertise in LNG shipping technology and StormGeo’s dominance in the weather services market make this partnership a natural fit for GTT. Sloshing prediction modules are the next step in ensuring the safest possible sea crossing for our LNG customers.”
