Last but not least, blockchain will noticeably save shipping costs, which are currently largely related to documentation, procedural delays, discrepancies or errors. Proving that the large part of transactions in shipping are related to document processing and administration, Maersk performed a research in 2014 and found out that a simple shipment of refrigerated goods from East Africa to Europe had to pass about 30 people and organizations, including more than 200 various communications among them. Marine Transport International estimates that the blockehain technology could save $300 per container in terms of labor and processing associated documents. For one ultra large container ship, which carries up to 18 thousand containers, the savings may reach $54 million.
