In recent years, many industries have adopted technology and digital systems to automate, expedite and secure specific processes. Stakeholders in maritime transport continue to exchange physical documents in order to conduct business. The monitoring of supply chain goods, communication among employees, environmental sustainability and longevity control, along with time framing, all create challenges to many industries. Everyday onboard work, such as cargo operations, navigation and various types of inspections in shipping, still requires paper documents and logs that need to be signed (and stamped). The conversion of traditional paper contracts into smart contracts, which can be digitalized and read through automation, provides a new wave of collaboration between eco systems across the shipping industry. Various data collected and stored on board ships could be used for scientific purposes. Distributed ledger technology (DLT) could be used to collect all those data and improve shipping operations by process expediting. It could eliminate the need to fill in various documents and logs and make operations safer and more environmentally friendly. Information about various important procedures onboard ships could be shared among all interested stakeholders. This paper considers the possible application of distributed ledger technology as an aid for the control of overboard discharge of wastewater from commercial ships. The intended outcome is that it could help protect the environment by sending data to relevant stakeholders in real time, thus providing information regarding the best discharge areas. The use of a structured communal data transference would ensure a consistent and accurate way to transmit data to all interested parties, and would eliminate the need to fill in various paper forms and logs. Wastewater overboard discharges would be properly monitored, recorded and measured, as distributed ledger technology would prevent any possibility of illegal actions and falsification of documents, thus ensuring environmental sustainability.

分布式账本技术作为航运业环境可持续性的工具

近年来，许多行业已采用技术和数字系统来自动化，加速和保护特定过程。海上利益相关者继续交换实物文件以开展业务。供应链商品的监控，员工之间的沟通，环境的可持续性和寿命控制以及时间框架，都给许多行业带来了挑战。每天的船上工作，例如货物操作，导航和运输中的各种检查，仍然需要纸质文档和日志，需要签名（盖章）。将传统的纸质合同转换为智能合同，可以将其数字化并通过自动化读取，这为整个航运业的生态系统之间提供了新的协作浪潮。收集和存储在船上的各种数据可用于科学目的。分布式分类帐技术（DLT）可用于收集所有这些数据，并通过流程加速来改善运输操作。它可以消除填写各种文件和日志的需要，并使操作更安全，更环保。所有感兴趣的利益相关者都可以共享有关船上各种重要程序的信息。本文考虑了分布式账本技术的可能应用，以辅助控制商业船舶废水的舷外排放。预期的结果是，它可以通过将数据实时发送给相关的利益相关者来帮助保护环境，从而提供有关最佳排放区域的信息。使用结构化的公共数据传输将确保以一致和准确的方式将数据传输给所有相关方，并且将不需要填写各种纸质表格和日志。由于分布式分类帐技术将防止任何可能的非法行为和伪造证件的可能性，因此将对船外废水进行适当的监测，记录和测量，从而确保环境的可持续性。
