A helmet and a pair of so-called Google glasses have opened new opportunities for the Finnish company Wärtsilä, which supplies engines and environmental equipment to the shipping industry. When a problem arises on board, one of Wärtsilä's experts can assist without setting foot on the vessel. They're called "virtual service engineers" and a digital system allows both parties to see what the other is doing and the on-land engineer can demonstrate exactly how a problem should be resolved.
