Do you trust that current maritime safety regulations are enough to prevent collisions in bad weather?
In 2026, two vessels collided within a Traffic Separation Scheme while navigating through thick fog. The incident resulted in significant damage to both ships after a failure to properly track targets in restricted visibility.
Why it matters
This collision highlights the critical dangers of inadequate radar tracking for non-AIS targets and the failure of vessels to adjust speed or sound necessary signals during periods of low visibility. The incident serves as a stark reminder of the risks present in busy maritime corridors when standard safety protocols are neglected.
The Nautical Institute officially documented the incident in Mars Report 202629. Authorities confirmed the collision involved one vessel traveling at 7.6 knots and another at 11.8 knots with an intermittent radar return.
The players
The Nautical Institute
This is an international representative body for maritime professionals that provides standards and reports on safety incidents.
The details
Vessel A was attempting to cross the traffic lane to comply with a suspension order when vessel B, which was not emitting an AIS signal, struck its port side. Both crews failed to sound the required long blast signals for restricted visibility, and vessel B attempted an unsuccessful evasive maneuver by steering hard to port.
Timeline
The collision occurred in 2026, as documented in Mars Report 202629.
Legal Context
This incident aligns with broader concerns regarding compliance with International Maritime Organization safety protocols for Traffic Separation Schemes. It follows a recurring trend of maritime accidents where failure to detect non-AIS vessels during low-visibility conditions leads to significant collisions.
The collision led to an immediate suspension of traffic within the affected scheme to ensure the safety of other vessels in the area. Such incidents often prompt stricter enforcement of AIS signal requirements and enhanced radar monitoring protocols for ships transiting international lanes.
The takeaway
Maintaining active radar tracking and adhering to sound signals during restricted visibility is vital for preventing collisions in busy shipping lanes. Mariners are encouraged to prioritize the detection of all nearby vessels, including those not emitting AIS signals, to ensure safe passage.
