Ice Navigation
By understanding Ice Navigation, we are indeed
promoting Safe Environment friendly marine
transportation
4
Knowledge of Ice Navigation is vital to ensure
  • Safe navigation
  • Minimising Sailing time
  • Avoiding delays
  • Environmental Safety

5

Navigation in ice requires special knowledge and
skills and it is expected that the guidelines
that were issued by IMO will be mandatory in the
near future, which will create standards for
training of navigators in ice.

Several countries have their own national rules
for navigating in ice covered waters that often
only apply to national flagged vessels.
6

What are the difficulties ?
  • No internationally accepted standards
  • Lack of standards and requirements come into
    conflict with growing oil exports and need of
    shipping companies to have crews qualified in Ice
    Navigation.
  • There is no internationally harmonised method of
    skill and knowledge delivery on Ice Navigation.
  • Constant improvement for instruments used in Ice
    Navigation
  • Not to forget the limitations of the WMO code

7

Navigators concerns ..
  • Icing on the ships structure may occur due to
    the freezing of sea sprays or due to snow, rain
    and fog. (Ships Stability / Equipment Failure)
  • Quickly changing weather conditions

8

Navigators concerns ..
  • Stoppages in ice breaker operations
  • Risk of Navigational errors in ice
  • Limitations of the Radar equipment in icy
  • areas.
  • Some case unable to follow traffic separation
  • zones in ice
  • Risk of Navigational errors in icy conditions
  • A strong growth in tanker traffic

9

Other concerns..
  • Ice may force the vessel into shallow waters
  • Ice pressure can seriously damage the vessel
  • The resistance of the ship is greater in level
    ice than in open water.
  • Handling a damaged ship in ice-covered waters

10

Example

No access to control or safety equipment might
prevent an adequate response to an emergency.
11


Combating oil spills in ice and cold waters can
be a daunting task
12

Training requirements

Do exist but Not mentioned in the STCW 95
13


The high expectations of customers and the safety
of crew, vessel, cargo and environment has become
a motivator to increase the knowledge and
experience of ships crews.
14

Entering the Ice .
  • Do not enter Ice if an alternative, although a
    longer route is
  • available.
  • It is very easy and extremely dangerous to
    underestimate the
  • hardness of the ice.
  • Be prepared to go full astern at any time.
  • Propellers and rudders are the most vulnerable
    parts of the ship
  • should go astern in ice with extreme care.
