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.

The global maritime digitalization reflects on navigation and paperless vessels with Paper Navigational Charts (PNC) nowadays superseded by Electronic Chart Display and Information System (ECDIS). Considering the system implementation and its acceptance as a sole navigational means, opinions of navigators differ. Although the ECDIS mandatory implementation ended in 2018, some navigators have been still favouring PNCs, pointing out their advantages over ECDIS navigation. These standpoints may have an impact on the safety of navigation in terms of acceptance, interpretation, and understanding of the system as well as on conflict of standpoints of decisive navigational ranks, the latter reason being found as one of the real problems. The presented study has focused on a specific period, soon after the transitional period completion, aiming to determine the views of traditional navigation advocates, their arguments in the present maritime navigation paperless era and to identify potential problems emerging from the conflict of two navigational means. The research has induced two independent, internationally distributed questionnaires, dedicated to navigational ranks. The first survey has referred to the period from 2012 to 2018, marking the transition to ECDIS navigation. The second survey was conducted after the implementation period completion date. The answers were analysed and discussed from the navigational ranks’ perspective, considering their competitiveness and the level of ECDIS education. The research results have indicated and confirmed that PNCs could not entirely be ruled out, at least at this stage. Besides definitive questionnaire answers, the findings have been supported with categorised comments as interpreted from the first survey questionnaire results. The paper aims to present the future of the PNCs, including possibilities of fusion with modern means. The proposed suggestions have been directed towards the benefits of maritime navigation safety, referring especially to disagreement between navigational ranks in terms of particular means acceptance.

This paper explores the impact of the Electronic Chart Display and Information System (ECDIS) on the safety of navigation and seafarers’ professional practices. As ECDIS has become the primary tool for navigation, its proper use is critical for ensuring safe maritime operations. Drawing on data from a questionnaire completed by 154 active seafarers, this research investigates how ECDIS influences situational awareness, the use and management of safety settings, training adequacy, and system-related challenges. The findings reveal that while most respondents recognise ECDIS as a tool that enhances navigational safety, significant concerns remain regarding human error, insufficient training, and inconsistent application of safety settings such as the safety contour. Additionally, steering errors during restricted water manoeuvres and system crashes emerged as recurrent safety concerns. The study highlights the need for improved standardisation, targeted training, and more effective integration of human and technological elements to ensure optimal ECDIS use. The results offer actionable insights for enhancing ECDIS implementation and maritime safety standards.
