One million seafarers, on board more than half the world’s shipping fleet, have now benefitted from the ShipVisitor welfare app, which helps to provide continuity of care as ships and their crew move from port to port. Developed by international charity Sailors’ Society, the app is used free of charge around the globe by 23 maritime welfare organizations, who provide chaplaincy support to seafarers far from home. Using AIS data provided by MarineTraffic, the app enables chaplains and ship visitors to report their activities in real time and maintain a history of ship visits and support provided to seafarers. This information can then be used to provide ongoing care and assistance as ship and crew continue their voyage.
