Insufficient fatigue monitoring in bridge watchkeeping poses a severe threat to maritime and inland waterways safety. Studies reveal alarming statistics, with 25% of marine casualties attributed to seafarers fatigue. IMO's research on seafarers fatigue revealed that one in four seafarers admitted to falling asleep while on watch.



The Bridge Navigational Watch & Alarm System (BNWAS), introduced two decades ago, falls short in addressing the complexities of modern watchkeeping. Dormant periods of 3 to 12 minutes and delegation of reset procedures exacerbate the issue.


Adapting to the Times

Sitting on the bridge during watchkeeping was once restricted. The shift to more sedentary watchkeeping practices with the advent of modern technology like ECDIS and flat-screen radar displays contribute to problem.

MAIB Bridge Watchkeeping Safety Study

A recent study delves into the complexities of fatigue-related accidents in bridge watchkeeping, revealing how prolonged duty periods and insufficient rest contribute to lapses in attention and judgment among watchkeepers.

According to the attached MAIB Bridge Watchkeeping Safety Study around the coast of United Kingdom, 66 accidents involving 75 vessels between 1994 and 2003 were attributed to a fatigued officer. As seen on this AIS map of the world's maritime routes, the UK coast occupies only a small percentage of total maritime traffic. By this analogy, it can be concluded that maritime accidents caused by fatigue occur daily.

The study's insights into fatigue-related accidents during bridge watchkeeping serve as a call to action for the industry to adopt more sophisticated measures in combating this pervasive issue.


Aware Mate offers a solution by introducing fatigue cameras in bridge watchkeeping. With the advancements in technology and changes in bridge watchkeeping practices, the use of fatigue cameras has become feasible.

Surveillance camera

How Aware Mate Works

These cameras lock onto the irises of the watchkeeper's eyes and issue a loud warning if their eyes close or their head falls for a certain period. The intelligent face and eyeball tracking algorithm system, along with infrared technology, ensure accurate detection day or night.


Privacy and Security

Aware Mate does not require an internet or cloud connection, ensuring that no personal data is recorded, transmitted, or shared. All deep learning data is pre-trained to the device, providing a built-in solution.


Integration Capabilities

Aware Mate seamlessly integrates into existing Bridge Navigational Watch & Alarm System (BNWAS) setups. It's a versatile solution that enhances safety without disrupting daily bridge team duties.


Partnership with AXIS

For an Aware Mate technology demonstrator, Axis Communications AB from Lund, Sweden, is providing hardware and a sofware optimized for deep learning and intelligent facial analytics applications.

International Transport Federation (ITF) Fatique Report

An excerpt from this comprehensive ITF fatique report: Fatigue in frame again over bulker grounding - Lloyd's List, Tuesday April 18 2006

A FATIGUED master, alone and asleep on the bridge of his ship, caused the grounding of a British-registered bulker in the Baltic Sea last October, a Marine Accident Investigation Branch report has concluded, writes Michael Grey. On a voyage from Hamburg to Klaipeda, the 2,777 dwt Lerrix was being monitored by Warnemunde VTS when it failed to alter course and despite efforts to contact the ship was seen to run aground. The master, who had permitted the lookout to leave the bridge, had fallen asleep in the pilot chair.

The casualty is the latest in a considerable list of incidents in which fatigue has played a major part...



Enhanced Navigational Safety

Aware Mate directly contributes to maritime and inland waterways safety by using video detection technology to monitor and detect signs of fatigue in bridge watchkeepers. This innovative approach helps in preventing accidents that could be caused by fatigue, thereby enhancing the overall safety of maritime and inland waterways operations.


Continuous Fatigue Monitoring

The system employs advanced video detection techniques, including infrared technology and intelligent algorithms, to accurately monitor fatigue levels among watchkeepers. This capability ensures effective fatigue detection both day and night, offering a reliable solution to manage and mitigate fatigue-related risks.


Privacy Security Assurance

Aware Mate is designed to prioritize the privacy and security of the watchkeepers. It operates independently without the need for an internet connection and does not record, transmit, or share any personal data. This approach ensures that watchkeepers' privacy is respected while maintaining a focus on safety and fatigue management.
