Massive maritime data is available nowadays to tackle vital industrial challenges such as autonomous vessels and carbon neutrality. These data can be collected on board vessels and shared with maritime stakeholders (e.g., ship owners and ship operators) for various missions. However, the current industrial practice lacks of a standardized framework and infrastructure for data collection, sharing and analysis among different stakeholders. Moreover, the data integrity/trust is essential as tampering maliciously by any unexpected parties can severely undermine data trust and thus reducing the confidence of data utilization (e.g., results with AI). To address the above-mentioned challenges, this paper presents a solution using docker and blockchain named DataSafe to enhance data standardization and integrity. We also discuss several
