TP 15163E

1.0 Introduction

1. Recognizing that special risks of ice damage may exist in certain waters off the East Coast of Canada during winter and spring months and that these may affect safety and contribute to marine pollution; the following guidelines were developed and have been in effect since November 1979.

These Guidelines will be known as the "Joint Industry Government Guidelines for the Control of Oil Tankers and Bulk Chemical Carriers in Ice Control Zones of Eastern Canada" (JIGs ).

These Guidelines are in no way to be construed as interpreting, adding to, or detracting from existing statutory or regulatory requirements.

2. This 2012 edition updates the guidelines and reorganizes them for ease of reference. Transport Canada, Marine Safety and Fisheries and Oceans Canada, Canadian Coast Guard have updated these Guidelines in consultation with marine stakeholders. In this edition, some new ice control zones have been created by sub-dividing existing zones to better reflect areas of similar ice conditions (see Appendix A). This edition came into effect for the 2012-2013 ice season and may be amended as deemed appropriate.

2.0 Application

3. (i) These Guidelines apply to all laden oil tankers and to tankers carrying liquid chemicals in bulk when proceeding through an active Ice Control Zone in Eastern Canadian waters and fishing zones south of 60° North (see section 7).

(ii) These Guidelines may be applied from November 6 to July 31, and the period may be extended or reduced depending on prevailing ice conditions, as the Canadian Coast Guard may declare.

4. A Transport Canada Regional Director, Marine Safety, may on request, consider allowing alternative measures for any part of these Guidelines where it is shown that equivalent safety and pollution prevention measures will be taken by the ship.

3.0 Ice Control Zones

5. The Eastern Canadian Waters and Fishing zones south of 60° North are divided into Ice Control Zones as shown in Appendix A.

6. During the period specified in subsection 3 (ii), the Canadian Coast Guard may declare any ice control zone to be an active Ice Control Zone and promulgate this information via Notice to Shipping and Notices to Mariners. Information concerning the status of any Ice Control Zone may be obtained by contacting any Canadian Coast Guard Ice Operations Centre or the nearest Marine Communications and Traffic Services (MCTS) Centre.

7. The declaration that an Ice Control Zone is active will depend on a determination by the Canadian Coast Guard of the presence or expected presence of ice conditions dangerous to shipping. An active Ice Contro Zone will be de-activated when the Canadian Coast Guard decides that the risk no longer exists.

4.0 Guidelines to be Onboard

8. Any ship to which these Guidelines apply is expected to have a copy of these Guidelines on board. The owner, charterer or agent, should ensure that the master of the ship is informed of these Guidelines.

5.0 Ice Advisor

9. All ships to which these Guidelines apply should, when proceeding through an active Ice Control Zone, have on board at least one "Ice Advisor", who meets the requirements as prescribed in section 10.

10. The Ice Advisor should:

• (i) hold a nautical Certificate of Competency valid in Canadian waters for the class of ship concerned in accordance with the Canada Shipping Act 2001 for Canadian ships or International Convention on Standards for Training, Certification and Watchkeeping for seafarers (STCW) 1995, as amended, for non- Canadian ships;
• (ii) be medically fit according to the Marine Personnel Regulations SOR/2007-115 or the STCW Convention; and
• (iii) during the five-year period preceding the voyage, have held the position of Master, Senior Watchkeeping Officer or Ice Advisor, while making at least 6 one way trips totalling a minimum of 15 days experience navigating ice covered waters in an active Ice Contro Zone or Zones that require the ship to make extraordinary manoeuvres or to be assisted by an icebreaker.

For the purposes of subsection (iii), the term "Ice Advisor" refers to a person who has filled the position referred to in section 9 prior to January 1, 1995

6.0 Vessel Reporting

11. Ships in or approaching Eastern Canadian waters from sea must comply with Eastern Canada Vessel Traffic Services Zone Regulations and Vessel Traffic Services Zones Regulations, as appropriate.

Additional information may be requested by the regional Canadian Coast Guard Ice Operations Centre in respect to these Guidelines, including the name of the Ice Advisor.

12. While navigating in an active Ice Contro Zone, ships should report their position, ice conditions, speed and course to the appropriate regional Coast Guard Ice Operations Centre at 1200 UTC 1600 UTC, and 2000 UTC daily or at any other time(s) as requested or required. Ships that become beset and ships that request the assistance of an Icebreaker should report their status and position every four (4) hours until passage is resumed or icebreaker assistance arrives. Failure to transmit a status report wil automatically cancel a request for icebreaker assistance.

13. When a ship incurs damage or suffers a casualty, existing regulations require the master to report the incident or accident to ECAREG Canada, or to the local MCTS Centre as appropriate, at the earliest possible time.^{Footnote 1}

7.0 Compliance

14. Compliance with these guidelines will help facilitate the ship's passage through Eastern Canadian waters. However, lack of compliance, events or circumstances may require the Canadian Coast Guard and / or Transport Canada, to exercise powers as prescribed by the Canada Shipping Act 2001 where, in their opinion, there is an undue risk to safety or the marine environment, as the case may be.^{Footnote 2}

8.0 Operational Practices

15. Ships navigating through an active Ice Control Zone should take the following precautions to prevent ice damage and minimize the risk of polluting the marine environment;

• (i) should proceed at moderate speed having due regard to visibility and prevailing ice conditions, and taking into account the possibility of collision with random ice in open water;
• (ii) have two searchlights mounted for night time navigation;
• (iii) obtain current ice information and a recommended route to follow in the event their intended route crosses an active Ice Control Zone.

16. Ice information, prognostic ice charts and recommended routing information may be received by facsimile or other communications equipment. Refer to Part 4 General Procedures, Services and systems and Part 5 Environment Canada’s Marine and Ice Warning Forecast Programs of the publication Radio Aids to Marine Navigation (RAMN) for additional information.

17. All requests for Coast Guard icebreaker escort should be arranged by the master, the owner, or the agent on his behalf, by contacting the appropriate regional Coast Guard Ice Operations Centre, or the nearest Marine Communications and Traffic Services ( MCTS ) Centre.

18. Guidance on the design and construction of sea inlets under slush ice conditions is shown in Appendix B.

19. Between mid-December and mid-March, ambient air temperatures can reach minus 40 degrees Celsius. Recommended loading practice should specify an upper limit to the temperature of cargo being loaded in order to minimize the effect of thermal shock to the ship's structure.

Appendix B - Guidance on Design and Construction of Sea Inlets under Slush Ice Conditions

MSC/Circ. 504

1. Casualty Records indicate that ships that are not designed to classification rules for navigation in ice and that operate in slush ice conditions are prone to blockage of the sea water cooling intakes and related air vents by slush and/or spray ice. Such blockage has resulted in loss of cooling water to the ship's main engine and/or generators, as well as structura damage to air vents or tanks upon continued operation of water pumps after vent blockage. Incidents have ranged from minor vessel delays to complete power failures which, in some cases, have resulted in groundings.

2. It is common practice to provide a supply of low pressure steam or compressed air to maintain clear cooling water intakes. However, experience has shown that such arrangements will not maintain clear inlets on ships operating in anything but the lightest ice conditions.

3. The following guidelines provide a suitable method to ensure that cooling water flow is maintained to the ship's engine and/or generator under such conditions.

3.1 The ship should be provided with at least one sea bay from which pumps supplying cooling water to essentia machinery can draw.

3.2 The sea bay should:

3.2.1 be supplied with water from at least two sea inlet hoses;

3.2.2 be connected to the sea inlet boxes by pipes, valves and strainers with a cross sectional area at least equal to the tota area of the suctions served by the sea bay; and

3.2.3 be vented to atmosphere by valved pipe of sufficient size to prevent tank over pressurization or under pressurization. 3.3. The sea inlet boxes should:

3.3.1 Be fitted on each side of the ship;

3.3.2 Be as deeply submerged as possible;

3.3.3 Have an area open to the sea of at least five times the total area of the pump suctions served by the sea bay;

3.3.4 Be fitted with a strainer plate at the ship's side having perforations approximately 20 mm diameter to prevent ingress of large ice particles;

3.3.5 Be fitted with a low pressure steam connection for clearing the ice strainer;

3.3.6 Have the vent pipe from the sea inlet sized to prevent ice blockage in the suction piping. On small installations, the cross sectional area should be at least equal to that of the suction piping. In the case of larger installations, the ratio may be reduced, but the minimum diameter recommended is 150 mm. The valve fitted should be of a full flow type; and

3.3.7 Have the valves meet the requirements of SOLAS regulation 11-1/48.3, protection against flooding, when used in unattended machinery space applications.

3.4 Diversion valves and piping should be provided at overboard cooling water discharges to permit warm water to be returned to the sea inlet boxes preventing ice blockages, and also to the sea bay to permit circulation in the event of total sea box blockage by ice.

4. Certain operating areas are noted for heavy spray ice accumulation during winter and precautions should be taken to avoid structural damage due to blockage of air pipes by spray ice. Air pipes serving cooling systems should be positioned in protected areas or heat traced as a preventative measure.

5. The attached sketch illustrates the layout of a recommended system.

IMO Suggested Arrangement (Port side view, Starboard side similar) - Elevation view

• Recirculation line with isolating valves
• Proportional reduction in sectional area may be suitable considering colder water
• Keep incoming water to sea strainer above 20° C
• High sea suction closed
• Low sea suction may need to be throttled
• Overboard discharge near shut to ascertain positive recirculation
