To respond to the compelling air pollution programs, shipping companies are nowadays setting-up on their fleets modern multi-sensor systems that stream massive amounts of observational data, which can be considered as varying over a continuous domain. Motivated by this context, a novel procedure is proposed that extends classical multivariate techniques to the monitoring of multivariate functional data and a scalar quality characteristic related to them. The procedure is effectively applied to a real-case study on monitoring of operating conditions (i.e., the multivariate functional data) and total CO2 emissions (i.e., the scalar quality characteristic) at each voyage of a cruise ship.
