Bridge Resource Management (BRM)
BRM applies communication, task allocation, challenge and response, and shared situational awareness to control human factors in bridge operations.
Operational Explanation
Bridge Resource Management (BRM) organizes the use of human and technical resources through closed-loop communication, clear task allocation, challenge and response, and a shared mental model. Investigations may identify these factors alongside technical, organisational and procedural causes; there is no universal percentage or identical taxonomy for every casualty.
Regulatory Reference
STCW Table A-II/1 expressly includes BRM principles in maintaining a safe navigational watch: resource allocation and prioritization, effective communication, assertiveness and leadership, situational awareness and team experience. Check certification requirements and SMS implementation; BRM is more than voluntary industry promotion. STCW A-II/1: Massachusetts Maritime Academy.
With a pilot aboard, agree the plan, limits, duties and communication arrangements; continue independent monitoring and promptly raise doubts or deviations. Use closed-loop communication: order, read-back and confirmation of execution, correcting misunderstandings immediately. MCA: watchkeeping with pilot aboard.
Scope of Application
Resource management during routine navigation and critical phases, including interaction with the pilot, engine room and shore support. BRM does not itself determine watch composition or authorize the OOW to act as sole lookout.
Procedure / How to Complete It
- Assign clear tasks to every bridge team member at the start of each critical phase of navigation (manoeuvre, port entry, heavy-traffic area).
- Communicate every relevant piece of information (position, traffic, intentions) explicitly and verifiably, never assuming it has been understood.
- Explicitly encourage challenge by every team member, regardless of rank, whenever something does not match expectations.
- Periodically verify that all team members share the same mental model of the situation (position, traffic, plan under way).
- Conduct a debrief after every critical phase, to identify any communication or coordination gaps that need correcting.

Practical Example
Example of good practice: during a port-entry manoeuvre, the helmsman verbally reports every course alteration carried out, the officer of the watch confirms receipt, and a third team member independently monitors the position via ECDIS, openly challenging any deviation perceived from the plan.
What Typically Goes Wrong
Investigations show recurring weaknesses in task allocation, communication, challenge and shared situational awareness. Their causal weight must be established in each event together with technical and organisational factors.
Common Mistakes Mistake Library
| Mistake | Consequence | How to avoid it |
|---|---|---|
| Tasks not explicitly assigned during critical phases, with overlaps or gaps in responsibility | No one monitors a critical aspect, assuming someone else is handling it | Always assign explicit, verifiable tasks at the start of every critical phase |
| Hierarchical culture that discourages challenge from more junior or lower-ranking team members | Errors evident to a team member go unreported out of deference | Explicitly promote a culture that encourages challenge regardless of rank |
| No verification that the whole team shares the same mental model of the situation | Decisions made on the basis of different information among team members | Periodically verify, out loud, that the shared understanding of the situation is genuinely aligned |
What the PSCO Checks
Operational Tips
- Treat BRM as a daily practice, not as a one-off course to complete and forget.
- Explicitly promote a culture of challenge and response, especially towards more junior team members.
- Use the debrief after every critical manoeuvre to identify communication gaps, not just to confirm the success of the operation.
Preparation checklist
Educational checklist. This summary supports learning and preparation only. It does not replace the vessel’s approved procedures, manuals, statutory documents, company SMS, or applicable official requirements. Completing it demonstrates neither compliance nor readiness for an inspection: it shows that a list has been read, not that the ship is in order. Always verify the current documents carried on board.
- Tasks explicitly assigned for every critical phase
- Communication verified, not assumed
- Culture of challenge and response actively promoted
- Shared mental model periodically verified
- Debrief conducted after every critical phase of navigation
