Understanding Communication for Safe and Efficient Ship Operation

Importance of Communication

• Objective: Understand good communication's role in achieving safe and efficient ship operation.
• Definition: Transfer of signals/messages to create understanding or a reaction.
• Types of Communication:
  • Writing, verbal, nonverbal, signs, and signals.
  • Can be one-way (e.g., written messages) or interactive.

Communication Problems and Their Impact

• Incidents: 70-80% of sea incidents linked to communication issues.
• Potential Causes:
  • Cultural, language, age, and experience differences.
  • Miscommunication between bridge and engine personnel, with tugs, other ships, VTS, ship owners, or authorities.
• Increased Workload: Bridge officers now handle more communication tasks.

Effective Bridge Communication

• Key Elements:
  • Clear, standard maritime English.
  • Mutual respect and confidence.
  • Professional attitude and workload sharing.
  • Good knowledge and bridge practices.
  • Self-confidence.

Addressing Communication Issues

• Historical Efforts: Various bodies have addressed maritime communication problems over the last century.
• IMO Publications: Standard marine navigational vocabulary updates.
• Sea Speak: Introduced the concept of message markers to reduce issues.
  • Research involved 1,000+ participants from 26 nations.

Sea Speak and Message Markers

• Purpose: Reduce communication problems between ships, shore, and VTS.
• Vocabulary: General English, maritime terms.
• Official Message Markers:
  • Question: Interrogative message.
  • Request: Action request.
  • Information: Facts.
  • Intention: Ship’s planned actions.
  • Warning: Dangers.
  • Instruction: Regulatory influence.
  • Advice: Recommendation.

VHF and Radio Communication

• Operator Certificates: General or restricted based on area.
• Responsibilities: Compliance with SOLAS, ITU radio regulations, and local rules.
• Watchkeeping: Continuous on channels DSC 70, 16, and 13.
  • Range: 20-30 nautical miles (VHF); 150-250 nautical miles (voice); 600-700 nautical miles (DSC).
  • High-frequency: Nearly unlimited range.
• Radio log: Record all safety-related incidents, communication summaries, and own ship position.

Incident Reporting and Equipment Testing

• Incident Reporting: Discharges or potential discharges of harmful substances must be reported.
• Equipment Testing: Avoid false alerts and maintain records.
• Drill Practices: Regular drills to prepare for emergencies.

Emergency Preparedness

• Mindset: Stay calm, think clearly, follow procedures.
• Familiarity: Officer of the watch must know and practice emergency procedures.
• Helicopter Transfers: Officers should consult the ICS guide.
