Competency in ECDIS navigation Christian Hempstead e-Navigation Conference 2010
Navigation (generally): • Transit from Point A to Point B safely • Includes at-sea passage & route planning • Depart point, present moment, destination • In-port with pilot aboard • Familiar vessel & power plant • Familiar navigation system
Consider these necessities of skillful use of ECDIS/ECS: • Increasingly carried on vessels under pilotage • Certification of all watch officers • Ship’s usage may impact pilot’s decision making • Expanding legal & regulatory expectations (trained crew, no-sail fault, etc.)
Most of all, the skillful use of ECDIS/ECS: • Depends on hours of no-consequence practice under pilotage conditions • Can include the “2-second glance” while preserving micro visual perception • Requires the non-distracting awareness of ambiguities in displayed information
The overarching goal in competency-based ECDIS training is the successful demonstration of “safe navigation with ECDIS”. What STCW now requires:
Results of incorrectly performed actions and skills: • Personal injury or loss of life • Harm to the environment • Significant damage to equipment
Critical ECDIS competencies So, we continue to avoid these by practicing critical competencies with ECDIS/ECS. • In marine piloting and navigation, this means: • Grounding • Allision • Collision • Near misses
3 critical ECDIS competencies • Maintaining situational awareness while using ECDIS including confirmation of primary position sensor accuracy by alternate means
3 critical ECDIS competencies • Safe monitoring of displayed information including the efficient adjustment to changing conditions
3 critical ECDIS competencies • Use of ECDIS functions involving the integration with other sensors • including AIS, ARPA and radar overlay , (when fitted and connected)
Some distinctions with ECDIS • Proficiencies (actions) lead to • Task Groups (middle skills) which lead to • Critical competencies which are assessed
So, how do navigators get good at doing this? Middle skills Task Groups Critical Competencies ACTIONS
Proficiencies are: • 90+ tasks organized by their priority to piloting & navigation • Broadly sequenced as: • Basic • Presentation of Display • Intermediate • Navigator
Navigation with ECDIS includes: • Underway transits • Track monitoring • Traffic management • Passage planning • Use of Track Control in autopilot
Defining middle skills creates access to the big, complex skills of the critical competencies: • route monitoring • correlation with the visual scene • an informative and unambiguous display and…
… more middle skills: • sensors working and connected and used • anti-grounding alarms set • settings adapted to changing conditions • route planning safety checks • user layers applied • appropriate updated chart portfolios
For example, Active monitoring is a middle skill: • Navigation is still visual and analytical • Active monitoring produces valid reliance • Verify displayed information • Adapt settings to conditions • Detect ambiguities & practice backups
Assessing ECDIS competencies The instructor’s role is to: • Demonstrate tasks, and structure the practice • Observe and analyze each trainee’s ECDIS navigation in a non-disruptive yet detailed manner • Score the effectiveness of ECDIS use as the trainee applies the tasks • Tally the scored tasks by groups
Assessing ECDIS competencies Sample ECDIS score sheet Task groups 1-5
Assessing ECDIS competencies Sample ECDIS score sheet Task groups 5-10

Achieving the objective • The training objective is simple: “Show me safe navigation using ECDIS” • The skills are numerous, the tasks focused • The integration of ECDIS skills with piloting tasks takes time and practice
Achieving the objective • The assessment of effective ECDIS use requires the context of coastal and confined navigation in visual ship piloting • Anything unsafe likely is the result of less than competent ECDIS navigation
In conclusion Demonstrate the safe and effective inclusion of ECDIS while piloting. Everyone happy. In piloting with ECDIS,there really is no middle ground: You are either safe, or unsafe, or lucky for a while.
