GTT launches LNG cargo monitoring tool
Designed for LNGCs, LNG Advisor is a new boil-off gas (BOG) monitoring system during LNG sea transport designed to provide on-board crews and onshore teams with real time reliable data on the energy performance of the ship.
Philippe Berterottière, Chairman and CEO of GTT, said: “LNG Advisor illustrates GTT’s ambition. Beyond the state of the art technologies we provide, we are keen to support ship owners and charterers in optimising the operational performance of their vessels. This will benefit all the LNG industry.”
He explained that GTT’s new service which provides reliable data on the ship’s energy performance is only a first step. The designer will further develop high performance systems helping crews to optimise their operations and reduce the losses related to boil-off gas.
LNG Advisor automatically monitors the engine and the gas combustion unit consumptions of boil-off gas, marine diesel oil and heavy fuel oil, as well as the natural and forced BOG during navigation.
Other influencing parameters such as the tank vapour pressure, the ship cruising speed and the ship motions are also continuously monitored. The system also features a tool that calculates the LNG saturated vapour pressure, therefore allowing analysis of the real thermodynamic state of the cargo.
Lastly, an LNG heel calculator is also included to help crews estimate the LNG required for the ballast passage.
