SIRE 2.0 Human Factors in Tanker Inspections
Human factors play a critical role in SIRE 2.0 tanker inspections, with particular attention to crew behaviour, decision-making, communication, situational awareness, leadership, teamwork and the practical implementation of procedures during real vessel operations.
Human Factors in OCIMF SIRE 2.0 Inspections
SIRE 2.0 represents a major shift in tanker inspection philosophy, moving beyond documentation and equipment checks to focus strongly on human performance, behaviour and decision-making during real onboard operations.
This reflects the importance of human actions, communication, operational discipline and organizational culture in maintaining safe tanker operations.
What Are Human Factors in SIRE 2.0?
Human factors refer to the behavioural and cognitive elements that influence shipboard operations. During SIRE 2.0 inspections, the practical interaction between people, procedures and equipment can be observed across different operational situations.
Decision-Making
The ability of officers and crew to make appropriate decisions when managing normal and high-risk operational situations.
Communication
Clear and effective communication between bridge, deck, engine and cargo-control personnel during vessel operations.
Situational Awareness
Awareness of vessel condition, cargo status, environmental conditions, equipment status and developing operational risks.
Leadership & Supervision
Effective leadership, instruction, supervision and intervention when unsafe conditions or deviations are identified.
Fatigue & Workload
Management of work and rest, crew alertness and watchkeeping effectiveness to support safe operational performance.
Team Coordination
Effective cooperation between departments and personnel during routine and critical vessel operations.
Why Human Factors Matter in SIRE 2.0
Tankers operate in high-risk environments involving hazardous cargo, strict environmental requirements and complex operational procedures. Under these conditions, human performance directly influences the effectiveness of risk controls.
SIRE 2.0 evaluates whether crews consistently demonstrate safe decision-making, effective communication and proper procedural application during real operational conditions.
Operational Risk
Human performance can influence the identification, assessment and control of operational risks during tanker activities.
Procedural Discipline
Procedures must be understood and applied effectively rather than simply maintained as documented requirements.
Team Performance
Effective coordination between personnel is essential during cargo operations, navigation, maintenance and emergency situations.
Safety Culture
Daily behaviour, communication and willingness to address unsafe conditions provide practical indicators of onboard safety culture.
Communication on Board
Communication is one of the most visible human factors during tanker inspections. Inspectors may observe communication between personnel during cargo, bridge, engine-room and other operational activities.
Bridge, Deck & Engine Communication
- Clarity between bridge, deck and engine teams.
- Effective coordination between departments.
- Clear exchange of operational information.
- Appropriate escalation of safety concerns.
Standard Maritime Communication
- Use of clear and appropriate maritime terminology.
- Confirmation of instructions.
- Clear communication during critical operations.
- Effective response to instructions under pressure.
Decision-Making During Tanker Operations
SIRE 2.0 observations may consider how decisions are made during real-time operational conditions, particularly when personnel are managing higher-risk activities.
Risk Evaluation
Personnel should consider operational risks before taking action and demonstrate awareness of the consequences of decisions.
Procedural Decision-Making
Decisions should remain consistent with applicable procedures even when operations are conducted under time or operational pressure.
Escalation
Appropriate operational issues should be communicated and escalated to the responsible level of authority.
Master–Officer Interaction
Effective interaction between the Master and officers supports structured decision-making and shared operational awareness.
Situational Awareness
Situational awareness reflects the crew's ability to understand current operational conditions, recognize developing risks and anticipate potential consequences.
Cargo & Machinery Status
Personnel should maintain awareness of cargo condition, machinery status, alarms and relevant system indications.
Environmental Conditions
Operational decisions should consider relevant weather, sea-state and environmental conditions affecting vessel activities.
Abnormal Situations
Crew members should recognize abnormal conditions and take appropriate action rather than focusing only on the immediate task.
System Interdependencies
Personnel should understand how actions affecting one system may influence other vessel systems or operations.
Leadership and Supervision
Leadership behaviour is an important indicator of onboard safety culture. Effective leadership provides clear direction while ensuring that procedures and safe working practices are consistently applied.
Clear Instructions
Personnel receive clear instructions and understand their responsibilities before and during operational activities.
Safe Practice Enforcement
Supervisors actively address unsafe practices and ensure that agreed controls are maintained.
Task Monitoring
Operational activities are monitored to verify that work is being conducted according to the agreed method.
Response to Deviations
Deviations from procedures or expected conditions are recognized, communicated and addressed appropriately.
Teamwork and Departmental Coordination
Effective tanker operations depend on coordination between bridge, deck and engine departments. SIRE 2.0 human factor observations may identify weaknesses where departments operate without sufficient shared operational understanding.
Cargo Operations
Bridge, deck and cargo-control personnel maintain aligned understanding during cargo preparation, transfer and completion activities.
Task Distribution
Responsibilities are clearly distributed and personnel understand their individual roles within the operation.
Effective Handovers
Operational information is transferred clearly during watch changes and task handovers.
Shared Understanding
Personnel maintain a common understanding of operational status, risks and required controls.
Fatigue Management
Fatigue can significantly affect human performance, alertness and decision-making in operational environments. Effective fatigue management therefore supports safe watchkeeping and operational performance.
Work & Rest Compliance
Work and rest arrangements should support applicable requirements and maintain adequate crew alertness.
Crew Alertness
Personnel performing safety-critical duties should demonstrate appropriate alertness and readiness.
Watchkeeping
Effective watchkeeping arrangements help maintain operational awareness during navigation, cargo and machinery operations.
Fatigue Mitigation
Practical measures should be used to identify and manage fatigue-related risks affecting operational performance.
Procedural Compliance in Practice
One of the important aspects of SIRE 2.0 is the difference between procedures existing in the Safety Management System and those procedures being effectively followed during actual operations.
Checklist Usage
Checklists should be actively used during relevant operations rather than treated solely as documentary requirements.
Permit-to-Work
Permit requirements should be understood, verified and implemented before controlled work begins.
Risk Assessment
Risk assessments should be relevant to the actual task and effectively implemented by personnel conducting the work.
Cargo Procedures
Cargo procedures should be understood and consistently applied throughout the operation.
Safety Culture and Behaviour
Safety culture is reflected through the daily attitudes and behaviours of personnel toward risk, operational discipline and unsafe conditions.
Stop Unsafe Work
Personnel should demonstrate willingness to stop or challenge unsafe activities when appropriate.
Near-Miss Reporting
Effective reporting of near misses supports identification of recurring risks and continuous improvement.
Open Risk Communication
Crew members should be able to communicate operational concerns openly and constructively.
Safety Participation
Active participation in safety discussions and operational controls supports stronger safety culture.
