The world’s first crewless, autonomously operated ship is set to sail in late 2018. The Norwegian-built Yara Birkeland is being dubbed the “Tesla of the Seas” because the vessel is fully electric. The $25 million ship will initially start out as a manned vessel, moving to remote operation in 2019 before going completely autonomous in 2020. The 100-container ship is being developed by two Norwegian companies — agriculture firm Yara International and technology company Kongsberg Gruppen. In
