**DEVICE MANAGEMENT AND ANALYSIS**

**FLEET MONITORING
FOR EFFECTIVE FISHERIES CONTROL**

ScreenOne is a web-based fleet monitoring platform designed for Fisheries Monitoring Centres (FMCs). It provides a clear operational picture of vessel activity based primarily on data collected from BlueTraker VMS transponders installed on board vessels.
Using position, course, speed, and event data transmitted by BlueTraker devices, ScreenOne enables monitoring, control, and analysis of fishing and other regulated fleets — in one unified interface. The platform can optionally integrate data from other tracking systems, allowing a combined view when needed.
For fleet owners who require only basic visibility of their vessels, SecondScreen Tuna is available as a simplified solution focused on vessel tracking without regulatory and control functionalities.

**CORE CAPABILITIES
OF ScreenOne PLATFORM**

**Map-Based Fleet Overview**
A central map interface shows vessels at their latest reported positions and supports fast operational orientation:
vessel status and reporting freshness at a glance
quick access to vessel details and latest messages/events
flexible views for different monitoring workflows

**Message History and Data Access**
Access a structured history of fleet messages and events for:
review within selected periods
filtering by message/event type and vessel
exporting data for additional analysis and archiving

**Voyage Replay**
Review vessel movements over a selected time period to support:
trip reconstruction and operational review
analysis of routes and behaviour patterns
preparation for follow-up actions and reporting

**Alerts and Event Management**
Monitor routine reporting and exceptional events derived from vessel and device activity, including safety, security, and operational alerts:
configurable alert rules and prioritisation
clear visualisation (map and lists)
acknowledgement workflows to ensure events are addressed and traceable

**Maritime Zones and Boundaries**
Manage territorial waters, EEZs, ports, and custom zones to
support zone-based monitoring:
entry/exit detection and related alerts
operational rules aligned with different areas
support for temporary or seasonal zones when required

**Fishing Effort Monitoring**
When vessels are equipped with BlueSenz sensors, ScreenOne can present fishing activity indicators alongside VMS tracking to support oversight of fishing effort and activity patterns.

**Electronic Logbook Oversight**
Provides access to electronic logbook data to support monitoring and consistency checks, including an overview of reporting completeness, visibility into catch-related information and trends, and support for identifying discrepancies that require follow-up.

**Reporting and Analytics**
Generate operational overviews and structured reports that support monitoring, investigations, audits, and recurring reporting workflows. Advanced analytics can be delivered through tailored reporting setups, including integration with external BI environments where required.

**Bidirectional Communication with Vessels**
Enables bidirectional messaging between the Fisheries Monitoring Centre (FMC) and vessels in its fleet. Messages can be sent to an individual vessel, a group of vessels, or the entire fleet.

**Commands and Device Management**
Centrally manage fleets equipped with BlueTraker VMS transponders to ensure reliable data collection and smooth operations:
remote device configuration and diagnostics
controlled device updates and maintenance workflows
consistent fleet-wide settings where needed

**Vessel Register and Harbour Management**
Maintain structured reference data required for monitoring workflows:
vessel registry with operationally relevant vessel details
harbour/port definitions that support trip identification and oversight

**User, Access, and Activity Logging**
Ensure secure and accountable system use:
role-based access management
full traceability of user actions through a dedicated log of changes and activities

**Certificate Module**
Document and formalise responses to incidents and operational events through a dedicated certification workflow:
certify events such as safety triggers, power loss, tampering incidents, port entry/exit, and other relevant occurrences
capture key incident information (time, vessel identity, description, actions taken, responsible personnel)
export certificates in PDF format for archiving, reporting, and regulatory documentation
maintain a structured history of certificates to support audits and accountability
