Chapter 1 provides the overall structure and framework for Part I of the Polar Code, as well as additional definitions not noted in the introduction, the requirements for the issuance of Polar Ship Certificates and surveys, and the general criteria for determining ship performance standards and operational assessments. These are clearly set out in the Chapter 1 wording below, and in the Part 1B Additional Guidance.

1.1 Structure of this part
Each chapter in this part consists of the overall goal of the chapter, functional requirements to fulfil the goal, and regulations. A ship shall be considered to meet a functional requirement set out in this part when either:
- .1 the ship's design and arrangements comply with all the regulations associated with that functional requirement; or
- .2 part(s) or all of the ship's relevant design and arrangements have been reviewed and approved in accordance with regulation 4 of SOLAS chapter XIV, and any remaining parts of the ship comply with the relevant regulations.
In addition to the definitions included in the relevant SOLAS chapters and the introduction of this Code, the following definitions are applicable to this part.
- 1.2.1 Bergy waters mean an area of freely navigable water in which ice of land origin is present in concentrations less than 1/10. There may be sea ice present, although the total concentration of all ice shall not exceed 1/10.
- 1.2.2 Escort means any ship with superior ice capability in transit with another ship.
- 1.2.3 Escorted operation means any operation in which a ship's movement is facilitated through the intervention of an escort.
- 1.2.4 Habitable environment means a ventilated environment that will protect against hypothermia.
- 1.2.5 Icebreaker means any ship whose operational profile may include escort or ice management functions, whose powering and dimensions allow it to undertake aggressive operations in ice-covered waters.
- 1.2.6 Ice Class means the notation assigned to the ship by the Administration or by an organization recognized by the Administration showing that the ship has been designed for navigation in sea-ice conditions.
- 1.2.7 Maximum expected time of rescue means the time adopted for the design of equipment and system that provide survival support. It shall never be less than 5 days
- 1.2.8 Machinery Installations means equipment and machinery and its associated piping and cabling, which is necessary for the safe operation of the ship.
- 1.2.9 Mean Daily Low Temperature (MDLT) means the mean value of the daily low temperature for each day of the year over a minimum 10 year period. A data set acceptable to the Administration may be used if 10 years of data is not available4 .
- 1.2.10 Polar Class (PC) means the ice class assigned to the ship by the Administration or by an organization recognized by the Administration based upon IACS Unified Requirements.
- 1.2.11 Polar Service Temperature (PST) means a temperature specified for a ship which is intended to operate in low air temperature, which shall be set at least 100C below the lowest MDLT for the intended area and season of operation in polar waters.
- 1.2.12 Ship intended to operate in low air temperature means a ship which is intended to undertake voyages to or through areas where the lowest Mean Daily Low Temperature (MDLT) is below -100C.
- 1.2.13 Tankers mean oil tankers as defined in SOLAS regulation II-1/2.22, chemical tankers as defined in SOLAS regulation II-1/3.19 and gas carriers as defined in SOLAS regulation VII/11.2.
- 1.2.14 Upper ice waterline means the waterline defined by the maximum draughts forward and aft for operation in ice.
- 1.3.1 Every ship to which this Code applies shall have on board a valid Polar Ship Certificate.
- 1.3.2 Except as provided for in paragraph
- 1.3.3, the Polar Ship Certificate shall be issued after an initial or renewal survey to a ship which complies with the relevant requirements of this Code.
- 1.3.3 For category C cargo ships, if the result of the assessment in paragraph 1.5 is that no additional equipment or structural modification is required to comply with the Polar Code, the Polar Ship Certificate may be issued based upon documented verification that the ship complies with all relevant requirements of the Polar Code. In this case, for continued validity of the certificate, an onboard survey should be undertaken at the next scheduled survey.
- 1.3.4 The certificate referred to in this regulation shall be issued either by the Administration or by any person or organization recognized by it in accordance with SOLAS regulation XI-1/1. In every case, that Administration assumes full responsibility for the certificate.
- 1.3.5 The Polar Ship Certificate shall be drawn up in the form corresponding to the model given in appendix 1 to this Code. If the language used is neither English, nor French nor Spanish, the text shall include a translation into one of these languages.
- 1.3.6 Polar Ship Certificate validity, survey dates and endorsements shall be harmonized with the relevant SOLAS certificates in accordance with the provisions of regulation I/14 of the SOLAS Convention. The certificate shall include a supplement recording equipment required by the Code.
- 1.3.7 Where applicable, the certificate shall reference a methodology to assess operational capabilities and limitations in ice to the satisfaction of the Administration, taking into account the guidelines developed by the Organization.
- 1.4.1 Unless expressly provided otherwise, ship systems and equipment addressed in this Code shall satisfy at least the same performance standards referred to in SOLAS.
- 1.4 2 For ships operating in low air temperature, a polar service temperature (PST) shall be specified and shall be at least 100C below the lowest MDLT for the intended area and season of operation in polar waters. Systems and equipment required by this Code shall be fully functional at the polar service temperature.
- 1.4.3 For ships operating in low air temperature, survival systems and equipment shall be fully operational at the polar service temperature during the maximum expected rescue time.
In order to establish procedures or operational limitations, an assessment of the ship and its equipment shall be carried out, taking into consideration the following:
- .1 the anticipated range of operating and environmental conditions, such as:
- .1 operation in low air temperature;
- .2 operation in ice;
- .3 operation in high latitude; and
- .4 potential for abandonment onto ice or land;
- .2 hazards, as listed in section 3 of the Introduction, as applicable; and
- .3 additional hazards, if identified.
