Question 1

Mid-manoeuvre, the Master notices the vessel's response to a routine engine/rudder combination feels subtly different than expected (perhaps due to an unexpected current effect), and pauses to reassess rather than continuing on the assumption that the vessel will "catch up" to the expected behaviour. The reassessment leads to a small adjustment and the manoeuvre completes safely. What does this illustrate?

Accepted Answer

Disciplined respect for an unexpected signal — even a subtle, hard-to-quantify deviation from expected vessel response is worth pausing for, rather than assuming the original mental model is still correct and pressing on; this kind of willingness to pause and recheck is a genuinely resilient practice, not indecisiveness A subtle deviation from expected vessel response is exactly the kind of weak, ambiguous signal that is easy to override mentally ("it's probably fine") and press on — the willingness to pause and genuinely reassess rather than dismiss the signal is a core resilient practice, particularly valuable because such signals are, by nature, easy to miss or rationalise away.

Question 2

During a berthing approach, an OOW notices a tug line has gone slacker than expected for the current manoeuvre phase and mentions it to the Master, who confirms the tug is repositioning and adjusts the plan slightly to account for the temporary reduced assistance. No incident occurred. What does this exchange demonstrate?

Accepted Answer

The "Monitor" resilience capacity in practice — the OOW noticed a subtle change in a system being relied upon (the tug line) and raised it before it became a problem, allowing the plan to be adjusted proactively rather than reactively; this kind of small, easily-overlooked observation is exactly what Safety-II asks teams to value and reinforce This is a clean example of why Safety-II asks teams to actively study uneventful moments — the value here is entirely in the noticing and the small adjustment, neither of which would appear in an incident log under a Safety-I-only approach, yet both are exactly the behaviour worth deliberately reinforcing.

Question 3

Before unberthing, the Master checks the tidal current tables and notices the current will turn during the planned manoeuvre window, then deliberately adjusts the timing of letting go to avoid the turn happening mid-manoeuvre. The unberthing proceeds smoothly. What resilience capacity does this best illustrate?

Accepted Answer

"Anticipate" — the Master looked ahead at a known, predictable future change (the tide turning) and adjusted the plan before it could interact unfavourably with the manoeuvre, rather than discovering the tide had turned mid-manoeuvre and having to react to it in real time Consulting the tide table is routine, but the deliberate act of using that information to actively reshape the timing of the manoeuvre — rather than just being generally aware of it — is what makes this a genuine example of the Anticipate capacity rather than just box-ticking.
