Question 1

A junior OOW, having read about Safety-II, argues that since "everyone is just adapting to variability," no individual should ever be held accountable for a manoeuvring error, since outcomes depend on system-level factors beyond any one person's control. Is this a correct application of Safety-II thinking?

Accepted Answer

No — Safety-II explains why things usually go right and provides a richer, fuller picture of safety, but it does not eliminate the need for sound individual judgement, competence, and accountability; a genuine error in judgement or a failure to apply known good practice still warrants honest review, just within a framework that also values understanding contributing system factors rather than seeking blame alone This question guards against a common misreading of Safety-II — it is not a free pass that removes individual accountability, it is an additional, complementary lens that explains why things usually go right and what should be reinforced, alongside (not instead of) honest, fair review of individual decisions when something genuinely goes wrong.

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.
