It is the most important part of voyage planning as this is the stage where all
necessary information is gathered for the plan, and therefore special attention
is required.
It is capital to have a very good idea of the risks involved, their evaluation in
order to choose best solutions whereby the level of the risk is balanced against
commercial suitability.

The Voyage Plan shall be compiled from berth to berth, and consequently will
include all navigation areas:
Ocean Navigation.
Coastal Navigation.
Navigation with Pilot.
6
Guidelines in constructing route:
Is the route prohibited by any Rule or Regulation ?
Is the route opposing any IMO recommendation ?
Is the route environmentally sensitive ?
Is the route politically sensitive or are there local considerations ?
Is the route risk assessment be regarded differently whether the vessel is
loaded or in ballast ?
Route shall comply with all rules and regulations issued by: Hydrographic
Office, Port Authority, and Department of Transport.
All TSS’s should be followed.
Generally, the minimum margin of safety from any coastline or danger,
should be of not less than 3 NM.
Masters are advised to may increase the safety margin, but never to
decrease it, unless forced by particular critical circumstances.

At this stage, the following aspects should be considered:
21
Traffic - special caution in heavy traffic area.
22
This is one of the primary responsibility of the OOW to comply with the approved
voyage plan, at all times, and whether any discrepancy noted, the Master be
immediately notified.
Major Concerns:
Ship Position - all available means must be used to ensure accuracy of
vessel’s position.
23
COLREG - COLREG regulations must be complied with at all
times; whether in doubt advise the Master.
