English is the official working language of the sea, mandated by the International Maritime Organization (IMO) for all international vessel operations. Every seafarer working on internationally trading vessels must have sufficient English proficiency to communicate safely with crewmates, port authorities, and other vessels. The IMO's Standard Marine Communication Phrases (SMCP) were developed specifically to ensure clear, unambiguous communication in maritime operations [IMO, 2001].
This guide provides a comprehensive pathway to developing English skills for merchant seamen, covering essential vocabulary, communication scenarios, learning resources, and certification requirements.
Before You Begin
- Understand the requirement: English proficiency is mandatory under STCW Regulation I/14 for all seafarers serving on vessels engaged in international voyages [STCW Code, 2010].
- Assess your current level: The Common European Framework of Reference (CEFR) levels A2 (elementary) to B2 (upper intermediate) are typical for seafarers depending on rank.
- Identify your focus areas: Navigation communication, engineering terminology, safety procedures, cargo operations, and social interaction all require different vocabulary sets.
- Available resources: IMO SMCP books, maritime English apps, online courses, and shore-based language training programs.
- Estimated learning time: 3–6 months to reach operational proficiency from a basic English foundation.
The Importance of English at Sea
English is not optional for international seafarers — it is a regulatory requirement and a safety-critical skill. The IMO made English the official language of the sea to ensure that crew members from different nationalities can communicate effectively during routine operations and emergencies.
Why English matters:
- Safety: Emergency communications, distress calls, and safety drills all use English
- Navigation: VHF radio communications with port control, other vessels, and VTS use English
- Documentation: Logbooks, cargo manifests, incident reports, and inspection records are in English
- Crew communication: Multinational crews use English as a common language
- Career advancement: English proficiency is required for promotion to senior officer ranks
Standard Marine Communication Phrases (SMCP)
The IMO SMCP is the standardized vocabulary and phrase set for all maritime communications. It was developed to replace ambiguous language with clear, standardized phrases.
Key SMCP Categories
1. Distress and Emergency Phrases
- "Mayday, Mayday, Mayday. This is [vessel name]. I am sinking. I require immediate assistance."
- "Pan-Pan, Pan-Pan, Pan-Pan. This is [vessel name]. I have a medical emergency."
- "Securite, Securite, Securite. This is [vessel name]. Navigational warning."
2. Navigational Phrases
- "What is your position?"
- "I am altering course to starboard."
- "My present speed is 12 knots."
- "I am at anchor in position..."
3. Port and VTS Communication
- "[VTS], this is [vessel name]. Request permission to enter port."
- "My draft is 12.5 meters."
- "I am proceeding to berth number 5."
- "Request pilot at [time]."
4. Cargo Operations

Port State Control Inspections
PSC inspectors will test your English during inspections. Common questions include:
- "What is your rank and duties on this vessel?"
- "Show me your certificate of competency."
- "Describe the emergency procedures for fire in the engine room."
- "What is the oxygen level in the cargo tank?"
- "Explain the operation of the inert gas system."
Crew Social Interaction
Social English is equally important for crew cohesion and mental wellbeing.
- Introductions: "Hello, I am [name]. I am the Third Officer."
- Daily conversation: "How was your watch? Did you sleep well?"
- Meal times: "Please pass the salt. The food is very good today."
- Cultural exchange: "Where are you from? How many days until your contract ends?"

Frequently Asked Questions
Do I need to speak English to work on a ship?
Yes, if you work on internationally trading vessels. STCW Regulation I/14 requires all seafarers to have adequate English proficiency for safety communication. Seafarers on domestic vessels in non-English-speaking countries may not require English.
What level of English do I need?
Minimum A2 (elementary) for ratings, B1 (intermediate) for junior officers, and B2 (upper intermediate) for senior officers. Some shipping companies require higher levels for specific roles.
How can I improve my English while at sea?
Practice with English-speaking crewmates, read ship manuals and documentation in English, listen to English radio broadcasts, use maritime English apps during off-duty hours, and keep a vocabulary notebook.
What is the SMCP?
The Standard Marine Communication Phrases (SMCP) is a set of standardized English phrases developed by the IMO for maritime communications. It covers navigation, safety, cargo operations, and port communications.
Is there a test for maritime English?
Yes. The MARLINS test is the most common maritime English assessment. It tests reading, listening, and vocabulary comprehension in a maritime context. Many shipping companies require MARLINS scores before signing contracts.
Conclusion
English proficiency is a fundamental requirement for every merchant seaman working in international shipping. From VHF radio communications and safety drills to cargo documentation and social interaction, English is the common language that enables multinational crews to operate safely and efficiently. Investing time in developing maritime English skills through SMCP study, vocabulary building, and regular practice with crewmates will improve your safety performance, career prospects, and quality of life at sea.
