Yesterday, Uwe Altenbach had the opportunity to speak at the International Maritime Organization on the topic of ‘Energy data on board as the key to operational optimization and reporting’.In his presentation, he emphasised that high quality measurement data is the necessary database for all further optimisation processes. Especially in combination with powerful ship performance software that uses high-frequency data, a solid basis for decision-making and robust modelling is guaranteed. Together with Hauke Hendricks, they also take the opportunity to talk to many partners and friends from the maritime industry.
