The Tanker Management and Self Assessment (TMSA) program was developed by the Oil Companies International Marine Forum (OCIMF) to improve safety management and operational excellence in tanker operations. TMSA provides a structured framework for shipping companies to evaluate, measure, and continuously improve their safety management systems.
This case study examines how a medium-sized tanker operator prepared for and successfully completed a TMSA inspection, highlighting the challenges faced, corrective actions implemented, and measurable improvements achieved.
Company Profile
Fleet Size: 12 oil and chemical tankers
Operating Area: Mediterranean, Middle East, and Asia
Employees: 450 seafarers and 80 shore staff
Certifications: ISM, ISO 9001, ISO 14001, ISO 45001
Initial Situation
- The company experienced several operational concerns over a two-year period:
- Increase in near-miss reports
- Two port state control deficiencies
- Inconsistent maintenance documentation
- Crew fatigue concerns
- Weak internal audit follow-up
Major oil charterers requested stronger evidence of compliance with TMSA expectations before approving long-term charter agreements.
The organization established the following objectives:
- Achieve compliance with OCIMF TMSA requirements
- Improve vessel operational safety
- Strengthen risk management procedures
- Reduce deficiencies and incidents
- Enhance crew competence and reporting culture
- Increase commercial opportunities with oil majors
| TMSA Element | Focus Area |
|---|---|
| Leadership & Management | Safety culture and accountability |
| Recruitment & Personnel Management | Crew competency and training |
| Risk Assessment | Hazard identification and mitigation |
| Incident Investigation | Root cause analysis |
| Navigation Safety | Bridge procedures and compliance |
| Cargo & Ballast Operations | Operational controls |
| Engineering & Maintenance | Planned maintenance systems |
| Management of Change | Change control process |
| Emergency Preparedness | Drills and response capability |
| Environmental Management | Pollution prevention |
Gap Analysis
A cross-functional team conducted a detailed gap analysis against TMSA Level 2 and Level 3 expectations.
Key Findings
- Incomplete KPI monitoring
- Limited trend analysis for incidents
- Lack of structured behavioral safety observations
- Inconsistent training records
- Delayed closure of corrective actions
Action Plan
The company implemented a six-month improvement program:
- Documentation Improvements
- Revised Safety Management System (SMS)
- Standardized inspection checklists
- Digitized maintenance records
Crew Training
- Bridge Resource Management training
- Engine room emergency drills
- Cargo handling simulations
Human factor awareness workshops
- Internal Audits
- Monthly vessel audits
- Shore management reviews
- Increased senior management vessel visits
The inspection was conducted over four days by an external marine auditor.
Day 1 – Opening Meeting and Documentation Review
The inspector reviewed:
- Safety Management System
- Training records
- Incident reports
- Maintenance logs
- Risk assessments
- Navigation procedures
- Observation
The company demonstrated strong documentation control but lacked sufficient evidence of trend analysis for recurring near misses.
Day 2 – Vessel Inspection
The inspector boarded one of the company’s Aframax tankers.
- Areas Examined
- Bridge operations
- Engine room condition
- Cargo control room
- Lifesaving appliances
- Firefighting equipment
- Permit-to-work system
- Housekeeping standards
- Positive Findings
- Excellent bridge team communication
- Well-maintained engine room
- High crew familiarity with emergency procedures
- Deficiencies Identified
- Expired calibration certificate for one gas detector
- Incomplete enclosed space entry checklist
- Delayed maintenance for one ballast valve
Day 3 – Crew Interviews
- Crew members were interviewed individually.
- Topics Covered
- Safety culture
- Fatigue management
- Incident reporting
- Emergency response
- Stop-work authority
- Results
Most crew members demonstrated good awareness of company procedures. However, junior officers expressed concern regarding workload during port operations.
Day 4 - Closing Meeting
The inspector summarized findings and categorized them as:
| Category | Number |
|---|---|
| Major Non-Conformities | 0 |
| Minor Non-Conformities | 3 |
| Observations | 5 |
| Best Practices | 4 |
The inspection outcome was considered satisfactory with recommendations for further improvement.
The company developed a corrective action plan within 14 days.
Immediate Actions
- Renewed calibration certificates
- Updated enclosed space entry procedures
- Completed overdue maintenance tasks
Long-Term Improvements
- Fatigue Management
- Revised work-rest scheduling
- Additional officer recruitment
- Digital fatigue monitoring system
Safety Reporting
- Introduced anonymous near-miss reporting
- Monthly safety trend analysis meetings
- Safety recognition program
Performance Monitoring
- Dashboard for KPIs
- Quarterly management review
- Benchmarking against industry standards
Operational Improvements
| Indicator | Before Inspection | After 12 Months |
|---|---|---|
| Near Miss Reporting | 25 reports/year | 78 reports/year |
| PSC Deficiencies | 7 | 2 |
| Lost Time Injuries | 3 | 0 |
| Overdue Maintenance Jobs | 14% | 3% |
| Crew Retention Rate | 76% | 89% |
Commercial Benefits
- Approved by two major oil charterers
- Increased charter opportunities
- Improved customer confidence
Cultural Improvements
- Stronger safety culture
- Increased crew engagement
- Better communication between ship and shore staff
- Senior management involvement is critical for successful TMSA implementation.
- Continuous improvement is more important than simple compliance.
- Crew engagement directly impacts inspection performance.
- Data analysis and KPI monitoring strengthen decision-making.
- Effective corrective action tracking prevents repeat deficiencies.
- Safety culture must be actively supported through communication and leadership.
Preparation Recommendations
- Conduct regular internal audits
- Maintain updated documentation
- Train crews continuously
- Monitor KPIs proactively
- Perform mock inspections
Operational Recommendations
- Strengthen management of change procedures
- Improve fatigue risk management
- Encourage transparent reporting culture
- Use digital tools for maintenance and compliance tracking
Strategic Recommendations
- Align TMSA goals with company business objectives
- Benchmark performance against industry leaders
- Invest in leadership development programs
The TMSA inspection process helped the company identify operational weaknesses and strengthen its safety management system. Although several deficiencies were identified during the inspection, the structured corrective actions resulted in measurable operational, cultural, and commercial improvements.
The case demonstrates that TMSA should not be viewed merely as a compliance exercise but as a strategic tool for continuous improvement, operational excellence, and long-term business sustainability in the maritime industry.

TMSA Implementation FAQ
OCIMF TMSA Goals
TMSA provides a structured framework for tanker operators to evaluate, measure, and continuously improve safety management systems beyond basic compliance.
Identifying Weaknesses
Common weaknesses often include poor KPI monitoring, lack of incident trend analysis, inconsistent records, and delays in closing corrective actions.
Crew Engagement
Crew engagement is critical; individual interviews verify that the safety culture is alive on board and that procedures are followed in practice, not just in documentation.
Fatigue Management
Effective fatigue management through optimized work-rest scheduling and digital monitoring is essential for maintaining operational safety and preventing incidents.
KPI Monitoring
Proactive KPI monitoring allows management to identify safety trends early, benchmark against industry leaders, and take necessary data-driven corrective actions.
Commercial Benefits
Achieving higher TMSA standards helps secure approvals from oil major charterers, significantly increasing long-term charter opportunities and market confidence.
