The detailed Passage Plan
shall
include the following factors:
x
The plotting of the intended route or course of the passage on appropriate scale charts: the true
direction of the planned route or course
shall
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;
x
Exact Offshore Installation positions
SHALL NOT
be used for GPS waypoints: always use an offset
position, preferably on the down-current side, of at least one nautical mile from the installation.
The main elements to ensure safety of life at sea, safety and efficiency of navigation, and protection of the
marine environment during the intended passage; such elements
shall
include, but not be limited to the
following:
x
Safe speed, having regard to the proximity of navigational hazards along the intended route or track,
the manoeuvring characteristics of the vessel and its draught in relation to the available water depth;
x
Necessary speed alterations on passage; where there may be limitations because of night passage,
tidal restrictions, or allowance for the increase of draught due to squat and heel effect when turning;
x
Minimum clearance required under the keel in critical areas with restricted water depth;
x
Positions where a change in machinery status is required;
x
Course alteration points, taking into account the vessel's turning circle at the planned speed and any
expected effect of tidal streams and currents;
x
The method and frequency of position fixing, including primary and secondary options and the
indication of areas where accuracy of position fixing is critical and where maximum reliability
shall
be
obtained;
x
Use of ships' routeing and reporting systems and vessel traffic services;
x
Considerations relating to the protection of the marine environment;
x
Contingency plans for alternative action to place the vessel in deep water or proceed to a port of
refuge or safe anchorage in the event of any emergency necessitating abandonment of the plan,
taking into account existing shore-based emergency response arrangements and equipment and the
nature of the cargo and of the emergency itself;
x
The details of the voyage or Passage Plan
should
be clearly marked and recorded, as appropriate,
on charts and in a Passage Plan or computer disk;
x
Security information
shall
be present in passage planning.
