Passage Planning

Question 1

Objective of Passage Planning

Answer 1

To develop a comprehensive navigation plan for the safe conduct of the ship from berth to berth.

Question 2

What’s in a Passage Plan?

Answer 2

Recognises hazards and assesses associated risks and decision points
* Ensures that sufficient sea room and depth of water is available
* Position fixing opportunities and intervals
* Reporting requirements and routeing measures for ships
* Anticipated traffic and weather conditions
* Complies with all applicable environmental protection measures.

Question 4

Stage 1: Appraisal

Answer 4

Gathering all information relevant to the proposed passage and reviewing it. Identifies and assesses risks to make sure that the proposed passage plan is safe.

• Navigation
• General /Operational
• Environmental
• Contingency
  *plus any other additional information

Question 5

Which books?

Answer 5

Sailing Directions
NtoMs
Ocean Passages of the World
Routeing charts and guides
Port Guides
List of Lights
List of radio signals
Tide Tables and Tidal Stream Atlas
Load Line Charts
Maritime Security Charts

Question 6

Stage 2: Planning

Answer 6

Developing and approving a passage plan based on the outcome of the appraisal of all relevant information.

*Ocean Waters
*Coastal Waters
*Pilotage Waters

Question 7

How do we plan on a chart?

Answer 7

No Go Areas
Safe Water
Under Keel Clearance
Tidal Window
Course Alteration and Wheel Over positions
Parallel Indexing
Transits and clearing marks for safe approach to harbours or anchorages
Position Fixing

Question 8

Setting UKC

Answer 8

• Squat of the ship
• The vessels Heeling and pitching movement.
• Reliability of charted depth data.
• Predicted tidal levels including if any expected negative surge.
• Areas of mobile bottom (silting/sand-waves).
• Any change in water density in passage (and its effect on draft).
• Accuracy of actual draft.
• Reliability of echo sounder
• The manoeuvrability of our vessel
• Ability to fix our position
• Ability to use a PI
• Reduced depths over pipelines and other obstructions.

Question 9

Parallel Indexing

Answer 9

means of continuously monitoring vessel’s track according to the passage plan
OR as a cross check reference to a GPS position.

Question 10

Stage 3 : Execution

Answer 10

Briefing the bridge team on the passage plan. Navigating the ship in accordance with the passage plan.

• Reliability and condition of navigational equipment.
• ETA at critical points for tide heights and flow.
• Daytime v night-time passing of danger points. Effects position fixing accuracy
• Traffic conditions
• Meteorological conditions, (particularly in areas known to be affected by frequent periods of low visibility) as well as weather routeing information.

Question 11

Weather Routeing

Answer 11

• Increased safety:
• Better conditions for cargo or passengers;
• Fuel and time savings;
• Reduced costs overall

Question 12

Stage 4 : Monitoring

Answer 12

Checking progress of the ship against the passage plan.

• Maintaining ships position within cross track error, including alterations of course to avoid a collision.
• Position fixing
• Cross-checking the ship’s position using all appropriate means, including:
• Visual and/or radar fixing techniques using ranges and bearing of charted objects.
• Echo sounder to monitor charted depths and contours
• Monitoring integrity of information displayed on navigational
  equipment.
