Your comprehensive resource for preparing for the UK Certificate of Competency oral examination

Introduction to the Master Unlimited Oral Examination

The Maritime and Coastguard Agency (MCA) Master Unlimited Certificate of Competency represents the highest level of deck officer certification under the STCW Convention. As the definitive qualification for commanding vessels of any size on unlimited voyages, candidates must demonstrate comprehensive knowledge across navigation, cargo operations, ship stability, safety management, and maritime legislation.

The oral examination assesses your ability to apply theoretical knowledge to practical scenarios at the management level. The examiner evaluates whether you can assimilate all available information affecting the safety and security of the ship, its passengers, crew, cargo, and the protection of the marine environment.

Regulatory Framework and Key References

Understanding the regulatory framework is essential for examination success. The MCA oral examination syllabus is contained in MIN 653 (M) Amendment 1 – Deck Oral Exam Syllabus. This Marine Information Note provides the complete syllabus mapped to STCW Code Table A-II/2.

Examination Structure and Assessment

The MCA oral examination is conducted online via Microsoft Teams. The examination can draw on any part of the MIN 653 syllabus and is designed to test your ability to apply knowledge to practical scenarios appropriate to the role of Master.

Assessment Criteria

According to MIN 653, the examiner bases the assessment on competence related to tasks, responsibilities, and duties necessary for:

• Ship operations

• Protection of the marine environment

The level of knowledge must be sufficient, in the examiner’s professional judgement, to enable you to serve in the capacity of Master and undertake management-level functions. Bear in mind that the Master has ultimate responsibility for the safety and security of the ship, its passengers, crew and cargo, and for the protection of the marine environment.

6. Medical Care – Organising medical care using the Ship Captain’s Medical Guide and obtaining radio medical advice

Bridge Resource Management and Human Factors

Bridge Resource Management (BRM) is a critical component of the oral examination. Candidates must demonstrate understanding of how human factors affect bridge operations and how to manage resources effectively to maintain safe navigation.

BRM Principles

• Resource Allocation – Assigning and prioritising resources based on operational requirements
• Effective Communication – Ensuring clear, unambiguous communication on board and ashore
• Assertiveness and Leadership – Demonstrating effective leadership behaviours and maintaining motivation
• Situational Awareness – Obtaining and maintaining awareness of vessel state, navigation path, and external environment
• Team Experience – Considering the experience levels of team members in decision-making

Human Factors in Bridge Operations

The examination assesses your ability to recognise and mitigate risks from human error, including:

• Fatigue management and hours of work/rest compliance
• Stress recognition and management
• Workload management during critical operations
• Challenge and response protocols
• Handover procedures

Stability Management

Stability is a critical examination topic. Candidates must demonstrate comprehensive understanding of stability principles and their practical application.

Core Stability Knowledge

• Fundamental principles: centre of gravity, buoyancy, and metacentre
• Effect of weight distribution on vessel stability
• Free surface effects and tank subdivision
• GZ curves and IMO intact stability criteria
• Difference between list and loll, with correction methods
• Changes in stability during the voyage
• Damage stability and watertight integrity

Stability Documentation

You must be familiar with the use of:

• The Master must not rely solely on the pilot but should monitor actions and intervene if necessary

Master-Pilot Exchange

Before pilotage commences, the Master should:

• Verify the pilot’s qualification for the area
• Provide ship characteristics and operational parameters
• Discuss any limitations or defects affecting manoeuvrability
• Agree the passage plan and contingencies
• Establish effective bridge team communication
