How to automate crew changes with Greywing + Dataloy

Shipping is complex. It is capital, labour and time intensive, they have complex operations, and they encounter plenty of unpredictability. Major factors influencing OpEx, such as fuel prices, weather, and macroeconomic shifts, are outside management´s control. For all of these reasons, businesses are focused intently on saving costs by streamlining crew changes, finding cost-effective flights and agencies, planning routes (or re-routing if necessary), and reducing delays, all of which have a trickle-down effect on the rest of the supply chain.

The integration between Greywing´s Crew Change and Dataloy VMS allows two parallel operations – crew management and voyage operations – to seamlessly connect for smoother operations with the robustness and detail needed to coordinate crewing procedures effectively.
