Section 1&2 - Voyage Planning Flashcards
What’s frequently lacking in proper passage planning?
- Navigational charts not up to date.
- Improper use of Electronic Chart Display and Information System.
- Lack of knowledge on ECDIS safety features.
- Lack of clarity on primary means of navigation.
- Courses not appropriately laid out on the charts.
- Vessel’s position not tracked / marked at suitable intervals.
- ‘NO-GO Areas’ not marked on the charts.
- Inoperative navigational and/or weather monitoring equipment.
- Inadequate assessment of weather.
What a proper passage plan should contain?
- True courses and distances.
- Methods and frequency of position fixing.
- Alter course and wheel-over positions.
- Margins of safety for each leg.
- ‘NO-GO Areas’.
- Abort Points / Point of ‘No-Return’.
- Wrecks and hazards in proximity of intended course line.
- Radar conspicuous objects (mark only the ones that are useful).
- Parallel indexing information.
- Reporting positions for Vessel Traffic Information System.
- Pilot Boarding Area.
- High density traffic areas.
- Weather assessment and monitoring.
- Static and Dynamic drafts.
- UKC.
- Air draft.
- Effect of tides and currents.
- Notes covering any useful/ relevant local information and regulatory restrictions.
Principles of a passage plan.
Its a requirement of:
- SOLAS (Chapter V Regulation 34)
- STCW Code
- A vessel’s SMS
- IMO Resolution A.893(21) ‘Guidelines for Voyage Planning’.
- Clearly define a safe navigational route from berth to berth.
- be comprehensive and detailed, reduce navigational risk and include contingency options.
- take into account established safety margins.
- satisfy a rigorous checking process.
- be easy to follow, allowing safe execution and monitoring of the plan.
- be economical.
The purpose of passage planning.
To develop a comprehensive navigation plan for the safe conduct of the ship from berth to berth.
To Adhere to legislative requirements
* Recognise hazards, and assess associated risks and decision points.
* Ensure that sufficient sea room and depth of water is available.
* Include appropriate position fixing opportunities and intervals.
* Comply with relevant reporting requirements and routeing measures for ships.
* Takes into account any cargo care sensitivities.
* Take into account anticipated traffic and weather conditions
* Comply with all applicable environmental protection measures.

The four stages of passage planning are given in IMO Resolution A893(21) [Guidelines for Voyage Planning] as Appraisal, Planning, Execution and Monitoring. Describe each of the four stages of the process
- Appraisal is gathering the information available, from all relevant sources, concerning the voyage from berth to berth and the appraisal report should be sent to the Master before proceeding.
- Planning involves making the fullest possible appraisal which consists of constructing the entire route together with the supporting information from berth to berth.
- Execution is where the final adjustments to the passage plan prior to departure are made by the OOW, using the charts and supporting navigational information provided by the navigator.
- Monitoring is conducting the voyage in accordance with the plan from departure to arrival, monitoring the ship’s progress and adjusting the plan if required while on passage.
