SIRE 2.0 Bridge Inspections: Human Factors and Compliance

Introduction: Why the Bridge Is the Heart of SIRE 2.0

In the modern maritime industry, the ship’s bridge is no longer assessed solely as a physical workspace equipped with navigational instruments. Under SIRE 2.0, the bridge is evaluated as a human-centred operational environment, where decision-making, situational awareness, procedural discipline, and communication converge.

The SIRE 2.0 Bridge Inspections now focuses heavily on how people interact with systems, how procedures are understood and applied, and how risks are managed during routine and non-routine operations. This shift reflects industry learning from incidents where equipment was available and functional, yet accidents occurred due to human factors, procedural drift, or breakdowns in bridge team management.

This article explores:

• What inspectors assess during a SIRE 2.0 Bridge Inspections
• The key questions inspectors ask and why they matter
• Common pitfalls and observations raised under SIRE 2.0
• The growing importance of documentation, records, and evidence
• How Mustr enables vessels and shore teams to meet SIRE 2.0 expectations with confidence

Understanding the SIRE 2.0 Philosophy on the Bridge

SIRE 2.0 Bridge Inspections has moved away from checklist-only inspections toward behaviour-based assessments. Inspectors no longer simply verify the presence of equipment or procedures. Instead, they assess:

• Familiarity and competence of Masters, officers, and crew
• Consistency between company procedures and shipboard practice
• Evidence that critical tasks are performed, recorded, and reviewed
• Quality of decision-making during critical phases of navigation
• Effectiveness of bridge resource management (BRM)

This approach means that bridge inspections are no longer about “what you have,” but about “how you use it.”

Pre-Use Testing of Navigational and Manoeuvring Equipment

What Inspectors Look For

One of the most critical areas of a SIRE 2.0 Bridge Inspections is the testing of navigational equipment, propulsion, steering gear, and thrusters prior to use and before critical phases of a voyage.

Inspectors assess whether:

• Officers understand company procedures for testing
• Functional tests are carried out before departure, arrival, anchoring, and high-risk transits
• Vessel-specific checklists are used correctly
• Results are recorded in logbooks or electronic systems
• Rudder movement timing tests align with manufacturer specifications
• Defects are reported and tracked systematically

Why This Matters

Many navigational incidents occur not because equipment fails unexpectedly, but because latent defects were not detected due to incomplete or superficial testing. SIRE 2.0 Bridge Inspections places strong emphasis on verification and consistency, ensuring that tests are meaningful, repeatable, and traceable.

How Mustr Helps

Mustr:

• Digitises vessel-specific pre-departure, pre-arrival, anchoring, and restricted visibility checklists
• Ensures no checklist item is left blank without justification
• Links checklist completion to logbook entries automatically
• Flags overdue or missed tests before inspections
• Centralises defect reporting and corrective actions for bridge equipment

Nautical Publications Management Under SIRE 2.0

Inspection Focus

Inspectors assess whether Masters and navigation officers are familiar with company procedures for:

• Ordering and managing nautical publications
• Maintaining an up-to-date inventory
• Ensuring publications are corrected to the latest edition
• Managing electronic publications and backups in line with flag approval

This includes verifying:

• Presence of mandatory publications (e.g., IAMSAR, International Code of Signals)
• Approval for electronic publications under SOLAS Chapter V
• Availability and currency of backups
• Accuracy of correction records

Common Observations

Negative observations often arise when:

• Officers cannot explain the publication management procedure
• Inventories are outdated or incomplete
• Backup systems are missing or unapproved
• Publications are obsolete or uncorrected

Mustr Advantage

Mustr enables:

• Digital inventories with automatic update reminders
• Evidence-based verification of publication status
• Easy presentation of compliance during inspections

Bridge Team Composition and Engine Room Operating Modes

SIRE Expectations

Under SIRE 2.0 Bridge Inspections , inspectors scrutinise:

• Whether company procedures clearly define bridge team composition
• Alignment between passage plans and actual watchkeeping practices
• Records confirming compliance during all voyage stages
• Understanding of when enhanced bridge teams are required
• Compliance with lookout requirements and hand-steering policies

Inspectors also assess whether:

• Changes in team composition are recorded
• Non-navigational tasks are managed without degrading situational awareness
• Engine room operating modes align with navigational risk

Human Factor Emphasis

This area strongly reflects human factor risk control. Fatigue, distraction, and role ambiguity are recognised as key contributors to navigational incidents.

Machinery Space Operating Mode Awareness

SIRE 2.0 Bridge Inspections now closely examine coordination between the bridge and engine room. Inspectors assess:

• Familiarity with machinery space operating modes
• Understanding of attended vs unattended requirements
• Communication of engine room status
• Recording of changes in machinery space status

Failures here often indicate organisational disconnects, rather than equipment issues.

Mustr bridges this gap by:

• Linking passage planning with machinery status requirements
• Ensuring clear communication records
• Providing traceable evidence of compliance

Pilot Integration and Master-Pilot Exchange

Why It Matters

Poor pilot integration has been linked to numerous maritime incidents. SIRE 2.0 Bridge Inspections therefore places strong emphasis on:

• Structured Master-Pilot exchange
• Accurate recording of conn transfers
• Use of pilot cards and checklists
• Documentation of equipment limitations and manoeuvring data

Common Failures

Inspections often identify:

• Incomplete or missing pilot exchange records
• Officers unfamiliar with checklist content
• Failure to record conn transfers
• Outdated pilot cards following modifications such as EPL

Mustr Capability

Mustr:

• Standardises Master-Pilot exchange documentation verification based on SIRE 2.0 questionnaire
• Ensures completion before operations proceed
• Maintains historical records for inspection review
• Flags missing or inconsistent entries

Managing Distraction and Disruption on the Bridge

SIRE 2.0 Bridge Inspections Human Factor Lens

Inspectors now assess whether:

• Procedures exist to prevent distraction
• Officers understand mobile phone and device restrictions
• Bridge access is controlled
• Non-essential activities are managed
• Multifunctional bridge layouts are risk-assessed

Why Inspectors Care

Distraction has been identified as a primary causal factor in navigational accidents. SIRE 2.0 demands evidence that companies actively manage this risk.

Emergency Communications and GMDSS Readiness

Inspection Scope

SIRE inspections assess:

• Familiarity with distress, urgency, and safety message procedures
• Availability of IAMSAR Volume III
• Accuracy of GMDSS logbooks
• Equipment testing, maintenance, and battery management

Inspectors also evaluate whether officers can explain and demonstrate emergency communication procedures.

Mustr Integration

Mustr:

• Centralises GMDSS testing records based on SIRE 2.0 questionnaire

EPIRB, SART, and Survival Craft Communications

Inspectors expect officers to:

• Demonstrate operation and testing
• Explain false activation procedures
• Verify expiry dates and condition
• Maintain accurate records

Failures here often reflect training gaps, not equipment failures.

DP Operations and Advanced Bridge Assessments

For DP vessels, SIRE 2.0 Bridge Inspections extend to:

• Annual DP trials
• Position reference systems
• DP incident reporting
• DP operations manuals
• Field operations manuals

Inspectors evaluate not just documentation, but operational understanding and learning culture.

Why Mustr Is Built for SIRE 2.0 Bridge Inspections

Mustr is not a document repository. It is a decision-support and compliance platform designed around how SIRE 2.0 Bridge Inspections are actually conducted.

It helps by:

• Translating complex inspection questions into actionable workflows
• Mapping evidence to inspection expectations
• Reducing human error through automation
• Supporting crew competence and confidence
• Providing shore teams with real-time visibility

The Real Value: From Inspection Survival to Operational Excellence

SIRE 2.0 Bridge Inspections are no longer events to “get through.” They are windows into operational culture. Vessels that perform well are those that embed compliance into daily operations.
