The International Maritime Organization (IMO) has launched a global survey to assess the implementation and use of Maritime Single Windows (MSWs), inviting feedback from organizations and individuals involved in maritime information exchange. 

What is a Maritime Single Window? 

A Maritime Single Window (MSW) is a centralised digital platform that enables the streamlined exchange of information among ships and various government agencies during port calls. Its use became mandatory under the IMO Convention on Facilitation of International Maritime Traffic (FAL Convention) on 1 January 2024. 

MSWs are a key component of shipping digitalization: they provide a single electronic entry point for the submission of information required when ships arrive in, stay at and depart from ports. By enabling data to be submitted only once and then shared among relevant authorities, MSWs help reduce administrative burdens, improve efficiency and transparency, and facilitate smoother port operations. 

Why a survey? 

Two years after this requirement entered into force, the survey aims to provide a clearer picture of how MSWs are being used across countries.  

The findings will identify implementation challenges, good practices and capacity-building needs, supporting countries in their efforts to further modernize maritime transport procedures.  

This exercise forms part of IMO's ongoing work to support Member States in implementing the FAL Convention and advancing maritime digitalization through technical cooperation.  

Who should participate 

The survey is open to maritime administrations, port authorities, customs and border control agencies, port community system operators, shipping companies, ship agents, terminal operators, freight forwarders and other stakeholders using MSW systems. 

A follow-up survey is planned for 2028 to assess progress since 2026 and measure the impact of MSWs on users' workload and operational efficiency. 

Take part in the survey 

IMO encourages all organizations and individuals involved in maritime information exchange to participate and share their experiences.
