Passage Planning Flashcards
Appraisal
Consulting with IMO A.893, SOLAS CH5, STCW ch 8. BPG ch 3. And following vessels SMS -
Check that….
The condition of the vessel and operational limitations
Well rest crew to under take the voyage
Talk with captain - Know when, where, which route, speed, stops. Bunkers , crew . Know and understand the masters preferences/expectations.
gathering all information relevant to the contemplated voyage or passage from berth to berth and assure all relevant documentation and publications are Up-to-date.
- Charts - larger scale and up to date
- Sailing directions
- NP 100
- List of lights and light radio aids to navigation
- Current tide atalases and tide tables
- All meteorological information
- All weather routing services - ( from volume D of the World Meteorological Organization’s Publication No. 9)
- routing charts
- almanac
- Ships routing guide - every TSS in world
- Traffic likely to be encountered
- pilotage needed?
- Port information needed
Gnomonic Charts – ocean passages - show the great circle route
Routeing Charts – ocean passages – shows routes between major
ports, ocean currents, trade winds etc.
Ocean Passages of the world – similar to routeing charts – vol 1, Atlantic & Med, vol 2 rest of world
Mercator Charts - coastal navigation, rhumb lines (yachting) – parallel to each other Charts are up to date – Admiralty Notice to Mariners (cumulative list, annual summary)
Planning
First
No go areas - where I cant go so I no where I can go
Calculated with draft, squat, company/masters UKC = critical graph. (If we need HOT we can use it )
Abort lines - once we cross we are full committed when cant do a 180 turn (3 point turn is possible for small vessels)
Contingency anchorages - doesn’t mean designated anchorage (correct depth and ground for holding)
Drawing what we gathered in the appraisal stage on to paper
Plotting of the intended route or track of the voyage or passage on appropriate scale charts: the true direction of the planned route or track should be indicated, as well as all areas of danger, existing ships’ routeing and reporting systems, vessel traffic services, and any areas where marine environmental protection considerations apply;
The method and frequency of position fixing, including primary and secondary options, and the indication of areas where accuracy of position fixing is critical
- Highlight hazards (no-go areas, isolated dangers, high traffic areas TSS
- Conduct chartwork (waypoints, W/O points, X-track, PI’s)
- Select lights that would be used for clearing bearings
- Obtain weather & tidal information
- Arears switching NAVTEX for MSI broadcasts
- Decide on Safety Contour & Safety Depth
- Obtain Distances (calculate fuel needed)
- Obtain Times (allows us to know manning levels at the correct times)
- Contingency plans (berths, anchorages) (make them known on the plan)
- Plan complies with international regulations and legislation
- ECDIS – System Route Check
- Second opinion from Chief Officer
Execution
Having finalized the voyage or passage plan -
ETD and ETA, Lines men ,tugs, every on board, engineers online, pilot
Up to date tides, weather
.1 the reliability and condition of the vessel’s navigational equipment;
.2 estimated times of arrival at critical points for tide heights and flow;
.3 meteorological conditions, (particularly in areas known to be affected by frequent periods of low visibility) as well as weather routeing information;
.4 daytime versus night-time passing of danger points, and any effect this may have on position fixing accuracy; and
.5 traffic conditions, especially at navigational focal points.
Briefing with bridge team, tool box talk - officer who did the plan takes the lead on talk.
