Bridge resource management and challenge-and-response

Almost no accident has a single cause. What accident reports find, again and again, is a chain — a small error, a missed cross-check, an assumption nobody voiced, a doubt somebody had and did not raise. BRM exists to break the chain at any link.

Entry & progression

Watchkeeping is a team activity even when there is one person on the bridge. BRM is the discipline of using every resource you have — people, equipment, information, and time — and of building a bridge where the most junior person present will tell the master he is wrong.

The steep authority gradient

A yacht is a small, hierarchical, intimate workplace where the master may also be your friend, your employer's confidant, and the person who decides whether you get the season. That is a steep authority gradient, and a steep gradient is where the words I wasn't sure, but he seemed confident come from.

The gradient is not a flaw in the individuals. It is a property of the structure. It must be flattened deliberately, by the person at the top, out loud.

Challenge and response

The tool is a shared, agreed, escalating script. It works because it removes the need for the junior officer to invent the courage and the words at the same time, at the worst possible moment.

  1. State the observation. Captain, I'm showing the depth at 12 metres and shoaling.
  2. State the concern. I'm concerned we're inside the safety contour.
  3. State the solution. I suggest we come to starboard, to 190, and slow to 8 knots.
  4. Obtain agreement. Captain — do you agree? And if there is no answer, or the answer does not resolve the concern: escalate, or act.

WARNING — The final rung: take the con If the vessel is standing into danger and the person conning her will not respond, the watchkeeper acts. Alter. Slow. Stop. Sound the alarm.

You may be wrong, and you may have an unpleasant conversation afterwards. That is a very small price. Every grounding report in the world contains a junior officer who saw it coming and said nothing, and every one of them wishes they had had that unpleasant conversation instead.

The other half — the master's job

A challenge-and-response culture is created from the top or it does not exist. The master who says good catch, thank you to a wrong challenge gets ten more challenges, one of which saves the ship. The master who says do you think I don't know that? gets silence for the rest of his career, and eventually gets a hull survey.

Closed-loop communication

Say it, hear it back, confirm it. Starboard ten. — Starboard ten, ten of starboard wheel on. — Very good. It sounds like theatre until the night the helmsman hears port and you catch it in two seconds instead of two minutes.

Situational awareness — and how it dies

  • Fixation. One person, one problem, one screen, and nobody watching the ship.
  • Automation complacency. The autopilot is steering, ECDIS is monitoring, and nobody is navigating.
  • Fatigue. The most under-reported hazard on a yacht, and the one the season is built on.
  • Distraction. Guests on the bridge. The owner wanting a tour. A radio call. A phone.
  • Assumption. Someone believing a thing that was never said.

Every one of those has a countermeasure and every countermeasure is a person opening their mouth. That is the whole of BRM. The rest is vocabulary.
