Real-time data on the energy performance of the LNG carrier. Monitoring of the engine and the gas combustion unit consumptions of boil-off gas, marine diesel oil, heavy fuel oil, natural and forced BOG during navigation.
Real-time monitoring of sloshing activity inside each tank to make critical decisions to optimise LNGc operations. Advanced analytics to compare the sloshing periods and the vessel’s operational profile.
LNG is a living cargo, and its composition and thermodynamic properties will change over time. The LNG ageing module predicts the cargo thermodynamic evolution such as the methane number, holding time, calorific value, temperature and the pressure profile. This is also useful to remove the nitrogen content from the CII calculation for LNG carriers.
The sloshing virtual sensor technology is a unique fatigue prediction algorithm that is applied against the GTT tank digital twin to derive the relevant indicators allowing Alternative Survey Plan in order to reduce the frequency of tank inspections and save cash.
In order to improve the operation window of the offshore units, we provide a unique digital solution for live sloshing risk prediction based on the weather forecast, the ship particulars and the operating conditions. The operator can anticipate the potential unsafe periods and maximise the offshore unit’s operational window
Unloading or loading cargo can sometimes be jeopardised by sudden harsh weather conditions, especially when the tanks are in a partial filling condition. This decision-support tool helps you to reach a safe filling levels situation by suggesting tank-to-tank transfer sequence.
Roll-over is a violent phenomenon that must be carefully prevented. Two cargoes with different densities can generate a stratification, which can lead to a sudden inversion of liquid phases, generating extreme quantity of Boil-off Gas. The application assists on cargo management to prevent roll-over.
During Laden operations, it can happen that unloading constraints (ETA and discharge port) are changed. When this happens, the LNG cargo may be in unacceptable condition for the new discharge terminal. This tool, based on GTT’s experience in LNG process, allows to compute the BOG flow to generate in order to recondition the cargo based on latest charterer’s request while reducing the cargo loss (i.e. maximising the delivered cargo).
