As you might imagine, drones can provide a host of useful functions for the shipping industry. You can bet the entire industry is studying and actually testing use cases all over the planet. A.P. Moller Maeersk A/S, the worlds largest containership operator (by capacity) is deploying drones both at sea, and in and around ports, discovering multiple ways to save costs.
Shuttling mail, medicine, and spare parts are among some of the most obvious uses. More over, as costs to shuttle things back and forth decrease, new uses and more frequency of hauls will begin to occur. Hull inspections are another use where significant savings can accrue. And, improving safety of course is always a desire among operators, an area where drones have certainly shown to benefit other industries.
