Improve CII ratings using real-time gas data

“Typically, the data is transmitted to the bridge for analysis and yields actionable insight for engine efficiency and can be provided into power management systems, engine control systems, and voyage optimisation and reporting systems. The connectivity ensures efficient communication with operators on land and enables diagnostics and software upgrades,” said Mr Johnsrud.

Key features of Tunable’s gas analyser technology include its robustness against vibration, critical for maritime applications, and its ability to measure multiple gases simultaneously with high accuracy. This capability is achieved through an innovative sampling probe and programmable filter chip, enabling rapid and reliable gas analysis without the need for calibration gases or complex maintenance procedures.

One of the most significant advantages highlighted by Mr Johnsrud is the ability of Tunable’s technology to provide shipowners with actionable insights into their vessel’s emissions profile. By combining gas analysis with artificial intelligence and machine learning, shipowners can optimise their operations in real time, leading to reduced fuel consumption and lower emissions.

The key is the relationship of nitrogen in LNG. Typically, said Mr Johnsrud, this is around 0.3% in LNG from the Middle East. “Until now,” he said, “there has been reliance on cumbersome boil-off gas tables.” But nitrogen volume boil off gas can vary between 5-10%, depending on voyage length, speed, weather, vessel condition, engine and more.

“Keeping track of nitrogen volume can improve CII by 5-10%. Which means the shipowner can extend the lifetime of the vessels by two to three years, without doing other costly actions, like speed reductions, non-optimal routeing and so on,” he said.

Tunable’s gas analyser technology offers transparency in gas quality, facilitating better communication between shipowners and charterers, noted Mr Johnsrud. This not only aids in negotiation processes but also allows shipowners to make more informed decisions when tendering for new contracts.

He concluded that Tunable’s gas analyser technology marks a significant step forward in the maritime industry’s efforts to address environmental challenges and improve operational efficiency.
