Study Notes
-
Sailing directions provide essential information for ocean passage planning, including charts and guides, navigation hazards, weather patterns, pilotage details, regulations, port facilities, Notices to Mariners, lists of radio signals and lights, tide tables, tidal stream atlases, load line charts, maritime security charts, and Figure 3.4 for additional information.
-
Detailed passage plan preparation is important, covering the entire passage from berth to berth and following either paper charts or electronic charts only.
-
Bridge Procedures Guide (BPG) should be followed for paper chart or ECDIS planning with established procedures.
-
Pilotage phase includes anticipated waypoint arrival times, cross track distance, ocean and coastal phase identification, safety depths and contours, and clearing bearings/ranges.
-
Coastal phase includes conspicuous charted features, no-go areas, routeing and reporting requirements, safe water, tidal height and stream information, and decision points for critical maneuvers.
-
Ocean passage planning considers ocean currents, winds, ice limits, and load lines, as well as ocean routeing charts, load line charts, weather routeing services, and gnomonic projection charts.
-
Coastal passage planning factors include the importance of passing charted and other features at a safe distance, available depth of water and tidal information, availability of visual and radar fixing opportunities, ship's routeing and reporting measures, the reliability of the ship's propulsion and steering system, and environmental protection measures.
-
In pilotage waters, the passage planning should cover when the ship is in non-mandatory pilotage areas, when a pilot is embarked, or when pilotage is being conducted by a ship's officer holding an appropriate and valid Pilot Exemption Certificate (PEC).
-
The safety contour is a boundary between safe and unsafe waters, displayed on ECDIS, indicating potential hazards and triggering anti-grounding alarms.
-
Safety contour parameters should be set according to a ship's sailing draught, expected squat, UKC, and height of tide.
-
The officer in charge of passage planning must consider several factors when calculating the safety contour, including ship's sailing draught, anticipated squat, company required UKC, height of tide, and CATZOC values of the sailing area.
-
The safety depth allows for identification of safe and unsafe waters based on spot soundings and the safety depth value entered by the officer.
-
The deep contour represents the area where a ship will encounter shallow water effects.
-
The Category Zone of Confidence (CATZOC) value highlights the accuracy of depth data on charts.
-
The passage plan should be checked and approved by the Master, visually inspected on ECDIS, and amended if necessary to address changing circumstances or CATZOC values.
-
Weather routeing is an aid to navigation that allows the Master and bridge team to plan a route based on weather conditions, increasing safety and fuel efficiency.
-
A passage plan briefing should be conducted to ensure all bridge team members understand their roles and the passage plan.
-
Passage plans may need to be amended to reflect changing circumstances or conditions before or during a passage.
