Napa adds new tools
Finnish NAPA Group is continuously adding new modules to its Ships
Performance Systems (SPS) family of software tools for onboard use.
R
ecent additions to the NAPA suite of
onboard software performance tools
include NAPA Log, a data collection
and reporting system with an electronic
logbook that provides advanced reporting
systems ashore, and NAPA Power, a fuel
consumption optimisation system which
also includes weather routing functionality.
NAPA Log gathers synchronised and
time-stamped information from hundreds
