BRNKL Black Marine Black Box with Secure Recording and Vessel Telemetry
BRNKL Black is a military-grade vessel monitoring system and onboard data recorder built for defence, police, patrol and commercial marine operations. It captures synchronised video, vessel telemetry, GPS vessel tracking, impacts and alerts in one secure record with full trip replay for incident investigation.
For military craft, police vessels, Border Force, patrol boats, offshore wind CTVs and commercial workboat fleets.
The marine black box for professional vessels
BRNKL Black captures the operational picture that conventional monitoring systems miss. This onboard data recorder collects, time-synchronises and stores vessel telemetry from cameras, sensors and crew-impact inputs. You can replay full trips, investigate incidents and maintain secure evidence that stands up to scrutiny.
Deployed across defence, patrol and enforcement operations, BRNKL Black provides secure recording and military-grade vessel monitoring where every detail matters.
One onboard data recorder. Six operational roles.
Record every trip
Capture synchronised video, vessel telemetry, alerts, GPS position and sensor data into one secure onboard record.
Replay incidents in full
Use trip replay to review synchronised video, vessel telemetry, position, event triggers and impact data for any incident investigation.
Monitor vessel and crew impacts
Bring together vessel telemetry, crew-impact data and operational events to understand exposure during demanding high-speed operations.
Support condition-based maintenance
Connect to onboard systems and data networks to identify issues earlier and plan maintenance before failures become critical.
Operate offline-first
Data stays on the vessel in secure storage unless you choose to export or transmit through your own network or communications route.
Integrate with existing systems
Connect NMEA 2000, digital switching, cameras, CAN bus and sensor networks into a single onboard data recorder.
What BRNKL Black records and connects
Supporting incident investigation and compliance on high-speed craft
MGN 436 Amendment 5 focuses on reducing injury risk from whole body vibration, severe shocks and repeated impacts on small vessels. It reflects growing best practice around shock-mitigating technology and operational data. BRNKL Black does not replace risk assessment or operator judgement. It gives your team a stronger evidence base for incident investigation, trip replay and exposure review.
For direct helm-facing impact feedback, pair BRNKL Black with Wave Guardian or the most suitable impact monitoring pathway for the application.
Optional crew impact and shock exposure integration
For specialist high-speed craft assessment, BRNKL Black can be configured as part of a wider impact and shock exposure monitoring approach. This may include body-worn or helmet-mounted sensors, vessel-mounted accelerometers and, where specified by Mission Dynamics, an optional MAREC-related shock exposure data pathway.
Built for defence, police and commercial fleet monitoring
Defence and military craft
Military-grade vessel monitoring with secure recording, GPS vessel tracking and synchronised video for tactical craft operations.
Police and enforcement vessels
Onboard data recorder with synchronised video, vessel telemetry and trip replay for incident investigation and accountability.
Border Force and coast guard
Secure recording and GPS vessel tracking for patrol operations, border security and maritime enforcement.
Offshore wind CTVs
Fleet monitoring and vessel telemetry for crew transfer vessels operating in demanding offshore conditions.
Commercial workboat fleets
Onboard data recording, trip replay and fleet monitoring for workboat operators who need a clear operational evidence trail.
Professional high-speed craft
Synchronised video, vessel telemetry and incident investigation tools for any professional operator running fast craft in demanding waters.
Synchronised video, vessel telemetry and GPS vessel tracking across deck, helm and engine spaces. BRNKL Black brings every data source together on one timeline for complete trip replay and incident investigation.
Example use case: crew impact analysis with vessel telemetry
BRNKL reports that Black was used with a Special Operations Forces organisation to fuse vessel telemetry and biometric sensor data, helping analyse the physical effects of high-speed manoeuvres on personnel. The system combined body and head acceleration data from wearable sensors with vessel-mounted inputs, then brought those data sets together for synchronised review.
