18 Important Points Deck Officers Must Consider in Coastal And Congested Waters

Summary

Navigating coastal and congested waters demands high levels of concentration, skill, and time management from the Officer of the Watch (OOW). With heavy traffic, fishing vessels, and challenging conditions, officers must carefully balance tasks such as plotting, maneuvering, maintaining a sharp lookout, and avoiding collisions. Key considerations include using accurate charts, accounting for currents, following traffic schemes, and maintaining clear communication with the Engine Control Room and Vessel Traffic Services. Ultimately, the OOW must know when to involve the master for guidance, ensuring safe and efficient navigation in these hazardous waters.

Takeaways

• 😀 Stick to the master's orders for the best navigation strategy based on their experience and knowledge.
• 😀 Always use the most accurate large-scale chart available to ensure precision in navigation.
• 😀 Account for set and drift, as tidal currents and winds can cause deviations from the planned course.
• 😀 Identify and understand navigational marks before approaching and continuously monitor them during the voyage.
• 😀 Be mindful of strong tidal currents, which can cause unexpected deviations and impact vessel movement.
• 😀 Comply with traffic separation schemes to minimize risks and avoid unnecessary complications in busy waters.
• 😀 Use visual aids and combine them with charts to maintain an accurate position in congested waters.
• 😀 Adjust the course when needed to account for deviations and ensure safe passage in confined spaces.
• 😀 Keep a safe distance from navigational hazards like oil fields or shallow waters to prevent accidents.
• 😀 Remain vigilant and use available manpower to monitor fishing vessels and other traffic in coastal waters.
• 😀 Communicate regularly with the Vessel Traffic Service (VTS) to ensure smooth coordination of navigation tasks.
• 😀 Hand steering is often necessary in coastal and congested waters, requiring readiness and skilled personnel.
• 😀 Monitor the Under Keel Clearance (UKC) closely to avoid the serious risk of grounding.
• 😀 Coordinate effectively with the Engine Control Room (ECR) to ensure engines are ready for maneuvering when required.
• 😀 Log all relevant information during navigation, particularly video logs, for legal and operational purposes.
• 😀 Increase the Plotting Position Indicator (PPI) when waters become confined to maintain situational awareness.
• 😀 Adjust the course promptly if the vessel goes off track, especially when limited room is available for maneuvering.
• 😀 Call the master for advice before critical situations arise, using their expertise to avoid potential disasters.

Q & A

Why is it important for the Officer of the Watch (OOW) to follow the master's orders in coastal and congested waters?

The master's orders are based on their extensive experience and knowledge of the area. They can provide the most effective strategy for navigating safely through congested and complex waters.

What is the significance of using large-scale charts for navigation in congested waters?

Large-scale charts offer higher accuracy, which is critical in coastal and congested waters where small deviations in position can lead to significant risks.

How should the OOW account for set and drift during navigation?

The OOW must factor in the effects of wind and currents (set and drift), which can alter the vessel's intended course and speed. This requires continuous monitoring and adjustments to the vessel's trajectory.

Why is it essential to identify navigational marks early in the voyage?

Identifying navigational marks early allows the OOW to confirm the vessel's position and ensure it is on course. It also helps in avoiding hazards and making timely course adjustments.

What impact do tidal currents have on navigation in congested waters?

Tidal currents can significantly deviate the vessel from its intended course. The OOW must anticipate these effects and make necessary course adjustments to maintain safe navigation.

What is the importance of complying with traffic separation schemes (TSS)?

Complying with TSS rules helps avoid collisions and navigational conflicts, ensuring smoother and safer passage in areas with heavy maritime traffic.

How does the OOW ensure accurate position fixing in congested waters?

The OOW uses a combination of visual aids, radar, GPS, and other navigational tools to continuously update the vessel's position, ensuring the highest level of accuracy in congested waters.

Why should the OOW avoid navigating too close to hazards like oil fields and shallow waters?

Navigating too close to hazards increases the risk of accidents, such as grounding or collision. Maintaining a safe distance from these dangers helps mitigate potential risks.

How can the OOW maintain effective communication with Vessel Traffic Services (VTS)?

The OOW should report regularly to VTS, as they can offer assistance with traffic coordination, provide real-time updates, and help in resolving potential navigation issues in busy areas.

What role does hand steering play in coastal navigation, and why is it necessary?

Hand steering allows for more precise control of the vessel, which is crucial in narrow, congested waters. The OOW must ensure that someone is available and ready to steer manually when required.

How can the OOW prevent grounding in shallow waters?

The OOW should closely monitor the Under Keel Clearance (UKC) to ensure there is sufficient depth beneath the vessel. Regular checks and course adjustments help prevent grounding incidents.

When should the OOW involve the master in decision-making during coastal navigation?

The OOW should consult the master before making crucial decisions, especially when navigating in confined or hazardous areas. The master's experience can provide critical insight to avoid potential disasters.
