The need for a new mandatory IMO Polar Code
5
Less ice in polar waters opens up new shipping lines and opportunities leading to increased:
• shipping in polar areas attracting new and less experienced operators
• Oil & Gas exploration and production
• mineral recovery and export
• tourism - also with large cruise vessels
• use of new shipping routes
• focus on the vulnerable environment in Polar areas

Geographical and Dynamic Risk Picture
7
• The risk level strongly depends on the
geographical location; time of the year
with respect to ice-type, ice-coverage,
temperature, daylight etc.
• Thus the mitigating measures required to
address the identified hazards may vary
within polar waters.

Limitations to operations are defined by:
Actual Ice Class
Polar Service Temperature (PST)
Level of Winterization
Possible other design limitations
- and it is always the responsibility
of the Master to ensure that the
vessel is operated within these

Chapter 1. General
Certificate and Surveys
- Every ship to which this code applies shall have on
board a valid Polar Ship Certificate issued by the
Administration or an organisation recognized by the
Administration, RO.
- A record of equipment to be included
Operation temperature
– A Polar Service Temperature (PST) shall be specified
and shall be at least 10° C below the lowest MDLT for
the intended area and season. Systems and equipment
shall be fully functional under the Polar Service
Temperature
19
Operational assessment (1.5)
– In order to establish procedures or operational limitations, an assessment of the ship and
her equipment shall be carried out, taking into consideration the following:
– the anticipated range of operating and environmental conditions, such as:
– operation in low air temperature, ice, high latitude, potential for abandonment onto ice
or land and other identified hazards.

Chapter 2. Polar Water Operational Manual
The Goal: To provide the Owner, Operator, Master and crew with sufficient
information regarding the ship's operational capabilities and limitations in order to
support their decision-making process
The Manual shall include or refer to specific risk based procedures to be followed:
– in normal operations and in order to avoid encountering conditions that exceed
the ships capabilities
– procedures to be followed in the event of incidents in polar waters
– procedures to be followed in the event that conditions are encountered which
exceed the ships' specific capabilities and limitations
– procedures to be followed when using icebreaker assistance, as applicable
20
The Polar Water Operational Manual is new, mandatory
and has to be developed for the actual ship and planned
operation

Chapter 3. Ship Structure
The vessel to be built with materials suitable for the Polar
Service Temperature
Category A and B vessel to be built and ice strengthened
according IACS PC or built according to standard offering
the equivalent level of safety
Category C vessels need not to be ice strengthened
21
Category A

Chapter 4 and 5
Chapter 4. Stability and sub division
– The Ship shall have sufficient stability in intact condition when
subject to ice accretion (Requirement same or less than
specified in DNVGL Winterized)
– Designed to avoid icing and measures to remove ice
– A and B vessels to have sufficient residual stability to sustain
ice-related damages
Chapter 5 Water- and Weather-tight integrity
– all closing appliances and doors relevant to watertight and
weathertight integrity of the ship shall be operable, i.e. they
have to be heated or other means have to be used
– Means shall be provided to remove or prevent ice and snow
accretion around hatches and doors
22
• DNVGL Winterized, doors and hatches along escape routes shall
be kept ice free all time, anti ice. (Basic, Cold & Polar)
• Polar code, - “means to remove after accretion” is ok.

delivering the required functionality necessary for safe
operation of the ships, (i.e. impact from snow, ice and
low temperatures)
– ice accretion and/or snow ingestion and accumulation
– ice ingestion from seawater

rafts under expected environmental conditions,
– Protect equipment and systems against freezing and
icing
– Ensure proper material qualities for operations at the
