The Certification Paradox
ECDIS carriage requirements were introduced through 2009 SOLAS amendments that entered into force on 1 January 2011 and were phased in by ship type and build date from 1 July 2012 to 1 July 2018, the transition revealed a persistent gap between documentation and capability.
I have sailed as Master through this era, accumulating over eight type-specific certificates. As far as ECDIS goes, I am cleared for almost any vessel, yet after a four-to-five-month gap, returning to a system last used years ago feels like facing entirely “new equipment”.
As an auditor, I frequently see type-specific familiarisation checklists completed without a clear understanding of the system’s underlying logic. Completion is recorded and comprehension is assumed. A watchkeeper can join a vessel with valid certificates, face a different interface and operational logic, and still be cleared for watchkeeping.
What the Rules Require and What They Do Not
On paper, the system is structured. STCW mandates generic ECDIS competence , but it does not certify familiarity with the specific system installed onboard. That responsibility sits with the company under the Safety Management System (SMS). While administrations provide guidance, actual execution is left to shipboard processes.
A third layer has emerged through inspection and vetting, under regimes such as SIRE 2.0 and RightShip RISQ, holding a certificate is no longer sufficient.
That gap between digital inspection ambition and onboard execution is also visible in my earlier analysis of SIRE 2.0’s digital inspection model.
Officers are increasingly required to demonstrate how the system is used, covering route checking, safety settings, and alarm handling.
So the system operates across following layers:
- Training
- Familiarisation
- Verification
- Demonstration
All of them exist, yet they fail to ensure familiarity is continuous at the point of use. In practice, focus intensifies around inspection cycles, creating temporary “competence peaks”. Navigation, however requires that same proficiency during every watch, not just for an assessment.
Standardised Regulation, Non-Standardised Systems
Across the global fleet, officers rotate through ECDIS systems from manufacturers such as Furuno, JRC, Wartsila Transas, Sperry Marine, Kongsberg, MARIS, Consilium, Raytheon Anschütz, Tokyo Keiki, Kelvin Hughes, ChartWorld, and Totem Plus.
There is a field of differing interface philosophies and menu structures. While systems comply with IMO performance standards, each follows its own proprietary logic. Critical functions, such as safety settings, alarm behaviors, and route-check workflows are accessed through unique paths and menu layers depending on the manufacturer.
The industry recognized this gap through e-navigation initiatives. The S-Mode concept originally sought a standardized mode across all equipment. However, the adopted guidance in MSC.1/Circ.1609 (2019) shifted toward broader interface principles rather than a single, fully standardized operating mode. In practice, implementation remains uneven, while some elements appear familiar, the underlying operational logic continues to differ, leaving a gap at the point of interaction.
The same weakness appears in wider bridge architecture, where merchant ships still rely heavily on external and interface-dependent navigation systems rather than resilient independent references, as discussed in Inertial Navigation Systems: Why Merchant Ships Still Don’t Have Them.
Why the Training Model Does Not Close the Gap
The industry operates on a two-layer training model: Generic ECDIS training for baseline theory and Type-specific training to bridge system differences. In principle, this is sound but in practice, the model fails at a critical point: timing.
Type-specific courses are frequently:
- Completed months or years before joining the vessel.
- Delivered through Computer-Based Training (CBT), which often prioritizes “click-through” completion over actual retention.
- Disconnected from the specific software version or configuration found onboard.
Consequently, competence is deferred. A 2021 MAIB study confirmed that operational competence requires recent exposure, not just a historical certificate. Officers joining after a significant gap often learn the interface in real-time during live navigation.
This is not limited to ECDIS. I completed a digital logbook course for a vessel that did not even have the system installed. The requirement was clear but timing was not.
A year later, I have not used that system. The familiarity is gone.
What Investigations Show
The documented pattern in maritime accident reports highlights a recurring disconnect between functional equipment and operational performance.
- The CFL Performer Grounding: This is a primary example of the gap between ECDIS carriage and actual competence. The investigation found that while ECDIS was the primary means of navigation, the bridge team lacked a sufficient understanding of its functions, leading to route-checking that failed to identify hazards.
- The Muros Case: Here, ECDIS was used in a restricted manner during coastal navigation. Critical errors included safety settings being misaligned with the passage requirements and the use of inappropriate chart scales during route checks.
These cases demonstrate a consistent pattern: the equipment was functional and the data was available, but the human-system interaction did not support effective decision-making.

The Human Element: Over-Reliance and Bias
Reporting from CHIRP and the Nautical Institute suggests that when system logic is not fully understood, operators tend to rely on automation without challenge.
- Configuration Defaults: Parameters often remain at default levels or are adjusted without a clear operational reference.
- Alert Management: Alerts may be acknowledged without a full interpretation of their meaning.
This behavior aligns with automation bias and confirmation bias, where the risk develops specifically through the way the operator interacts with the technology.
The same danger appears when bridge teams accept convincing system outputs without enough challenge, a pattern I covered in GPS spoofing and false satellite signals at sea.
The “Default Settings Trap” and Automation Bias
When a certified officer joins an unfamiliar system, they begin a process of adaptation under load. Learning navigation menus via trial-and-error while managing vessel safety is a dangerous necessity.
The “Default Settings Trap” is a major, overlooked risk. Officers do not inherit a “clean” system; they inherit safety contours, alarm thresholds, and display layers shaped by the preferences of previous watchkeepers. Without a standardized “SMS Baseline” button, the officer may operate under a shifted configuration without realizing it.
This leads to Automation Bias. When an interface is cumbersome, the human tendency is to stop challenging the data. If a setting cannot be verified quickly, the officer may assume the system “knows best,” resulting in misunderstood alerts and ECDIS-assisted incidents.
The Industry’s Comfort Zone – Documentation
The maritime industry continues to rely on verifiable paperwork to provide measurable assurance of regulatory compliance. Companies, Port State Control, and auditors confirm certification records to validate adherence to established procedures. However, the operational focus is shifting; modern inspectors now require officers to demonstrate system use, specifically route verification, safety contour adjustments, and alarm handling.
This shift highlights the visible gap between documented compliance and operational familiarity. While current practices are beginning to address system use, they do not yet resolve the underlying structure that creates such wide variation in competence. Ultimately, the system validates the paperwork, but safe navigation depends entirely on performance.
Why Aviation Manages Recency and Type Transition More Explicitly
Aviation establishes a benchmark for managing system-dependent safety through explicit recency and type transition requirements. Under frameworks like the FAA and EASA, a pilot’s familiarity is maintained through recurrent training and periodic validation rather than assumed persistence.
Key structural advantages include:
- Consistent Design Philosophy: Within aircraft families, system logic, alert hierarchies, and interface behaviors are aligned for immediate recognition.
- Crew Resource Management (CRM): Reinforces shared situational awareness, ensuring both operators understand the system status in real time.
The fundamental difference lies in the structure of the human-technology interaction. Pilots are required to remain current through continuously validated, highly structured transitions.
What Needs to Change
The issue is not a lack of process onboard; it is a lack of alignment at the system level. Based on my experience across multiple systems, the technology remains consistent in capability, but the variation lies in how it is applied and understood at the point of use.
What needs to change:
- Training Alignment: Training must be aligned with the system in use at the time of joining. Exposure not linked to actual system use loses operational value over time.
- Recency over Certification: Certification cannot be treated as transferable across time and systems. A course completed years prior does not represent current familiarity with installed equipment.
- Standardization of Core Functions: Interface consistency must exist for core navigational functions. Route checking, safety parameter configuration, position monitoring, and alarm management should be executed in a consistent manner across all manufacturers. While additional features can vary, the core interaction should not.
The Requirement for Muscle Memory
True competence requires more than procedural knowledge. It requires instinctive familiarity. In aviation, consistent cockpit design enables this through repetition. In shipping, variation in ECDIS interaction prevents that familiarity from carrying forward.
In the maritime industry, the functions of the ECDIS in particular should be part of an officer’s muscle memory. This can only be obtained through a high degree of standardization. When an officer has to “understand the system again” every time they change vessels, they are deprived of the instinctive familiarity required for safe operations.
The same question will matter as newer bridge systems arrive, including VDES and AIS upgrades, where the real issue is what changes for the officer using the system, not only what changes technically.
What is required:
- A reduction in variation in how critical navigational functions are accessed and applied.
- Continuity between training, familiarization, and actual system use.
- Recognition that competence depends on current system exposure, not past certification.
Where the Framework Meets the Bridge
ECDIS has shifted navigation toward system-dependent interaction. The framework defines competence, but the system requires familiarity at the moment of use. Currently, that familiarity is not carried forward, it is rebuilt during live operations, where adaptation becomes a part of the operating model.
The industry has standardized the requirement. It has not standardized the experience.
Until competence is aligned with system familiarity at the time of use, the bridge will continue to carry a risk that certification does not address.
