Question 1

An experienced deckhand, without being able to fully articulate why, says a mooring line "doesn't look right" under load and asks for it to be eased and re-run. On inspection, a kink that would likely have caused premature failure is found and corrected. How should this event be regarded?

Accepted Answer

As a valuable demonstration that experienced, tacit pattern-recognition ("it doesn't look right") is a legitimate and valuable safety input, not just a feeling to be dismissed for lacking a precise technical explanation — this kind of intuitive expertise, built from experience, often catches things that a purely checklist-based inspection would miss Tacit, experience-based pattern recognition is a real and valuable form of expertise that does not always come with an immediately articulable explanation — dismissing it because it cannot be justified on the spot in checklist terms would mean losing exactly the kind of early-warning signal that prevented a line failure here.

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.
