Using Nemo

NEMO can be used through one or more access channels depending on your organization's needs and technical environment. The following options are available:

• National Declarant API (NAPI) – for submitting notifications to Finland.
• National Port API – for information exchange between port operators in Finland.
• AS4/RIM – for EU-wide information exchange.
• Web User Interface – NEMO's graphical user interface, which does not require system integration.

All channels process the same notification data and use the same code lists. Therefore, the selected channel only affects the method of data transfer, not the information that is submitted.

Choose the Appropriate Access Channel

National Declarant API
Choose the National Declarant API if your organization regularly submits notifications to Finland and wants to automate data transfer from its own systems. This option is suitable for shipping companies, agents, and other organizations operating primarily in Finnish ports. It is based on widely supported REST/JSON technology.

National Port API
Choose the National Port API if your port wants to receive and manage notification data directly in its own operational systems. This option enables automatic integration of NEMO data into port systems and provides direct access to information submitted for official reporting.

AS4/RIM
Choose AS4/RIM if your organization operates in multiple EU Member States and wants to use the common EU-level information exchange solution. It is particularly suitable for large organizations that already use systems supporting AS4/SOAP technology.

The solution requires a dedicated AS4 Access Point and the necessary agreements with the relevant Member State for sending and receiving messages. In return, it provides a harmonized information exchange mechanism across the European Union.

Web User Interface

Choose the Web User Interface if your organization does not require system integration.

Using the web interface at mnsw.mnsw.fiOpens in a new tab, users can submit port call notifications by entering the required information manually or by using the EU Harmonised Spreadsheet (Excel)Opens in a new tab.

The NEMO user interface includes common navigation elements, system notifications, and email notifications. Detailed instructions for individual functions are provided in separate guides.

Navigation

The NEMO user interface provides access to different views through the Main Menu at the top of the page and the Menu located in the upper-right corner.

Main Menu

The Main Menu contains the following navigation buttons: Home, Port Calls and Vessels. These buttons provide direct access to their respective views.

On desktop devices, the Main Menu is located at the top of the page. On mobile devices, it is displayed at the bottom of the screen.

From the Menu, you can:

• switch between organizations where you have user access
• join an existing organization or register a new organization in NEMO
• open Organization Management, if you have the required permissions
• open Delegation Management
• change the system language (Finnish, Swedish, or English)
• change the system theme (Automatic, Light, or Dark). In Automatic mode, the theme follows your operating system settings.
• access the NEMO Support website
• sign out

Date and Time Fields

The behavior of date and time fields in NEMO depends on your web browser, operating system, and regional settings.

For this reason, the input format may differ between users. For example, dates may be displayed as DD-MM-YYYY or YYYY-MM-DD, while times may appear as 13:45 or 1:45 PM.

These differences are determined by your browser or device settings and are not controlled by NEMO. The appearance and functionality of date and time pickers may also vary between browsers.

If a field contains a calendar or clock icon, you can use it to select a value instead of entering it manually.

System Notifications
NEMO displays brief on-screen notifications to inform users about events that require attention. These notifications may relate to port call reporting or other system activities.

Common notification types include:

• Missing information – A required field has not been completed. Enter the missing information before saving or submitting.
• Invalid information – A field contains invalid or inconsistent data that must be corrected.
• Operation completed – Confirmation that an action, such as saving or submitting, was successful.
• Reminder – A prompt to review information, confirm an action, or continue to the next step.

Email Notifications
NEMO sends email notifications as part of its normal operation. These messages may relate to port call reporting, organization management, or communication with authorities.

Email notifications are divided into two categories:

• Scheduled notifications are sent automatically when predefined conditions are met. For example, a notification is sent when a vessel certificate is about to expire or has expired.
• Action-based notifications are triggered by user actions. For example, when a user invites another person to join an organization, an invitation email is sent automatically.
