The ABS Steel Vessel Rules contain requirement for stability that match the International Load Line Convention. When ice accretion is likely to occur, ABS offers an ice accretion analysis as part of the climate hazard assessment service, additional stability assessments are required. Also when ice accretion is likely the vessel needs to have appropriate means of managing the ice buildup. The ABS Guide for Vessels Operating in Low Temperature Environments contains some helpful guidance for ship operators, but ABS through its Advisory Services, offers assistance to ship owners in selecting realistic and practical solutions to deal with ice accretion.

4.1 Goal
The goal of this chapter is to ensure adequate subdivision and stability in both intact and damaged conditions.
4.2 Functional requirements
In order to achieve the goal set out in paragraph 4.1 above, the following functional requirements are embodied in the regulations of this chapter:
- .1 ships shall have sufficient stability in intact conditions when subject to ice accretion; and
- .2 ships of category A and B, constructed on or after 1 January 2017, shall have sufficient residual stability to sustain ice-related damages.
4.3.1 Stability in intact conditions
- 4.3.1.1 In order to comply with the functional requirement of paragraph 4.2.1, for ships operating in areas and during periods where ice accretion is likely to occur, the following icing allowance shall be made in the stability calculations:
- .1 30 kg/m2 on exposed weather decks and gangways;
- .2 7.5 kg/m2 for the projected lateral area of each side of the ship above the water plane; and
- .3 the projected lateral area of discontinuous surfaces of rail, sundry booms, spars (except masts) and rigging of ships having no sails and the projected lateral area of other small objects shall be computed by increasing the total projected area of continuous surfaces by 5% and the static moments of this area by 10%.
- 4.3.1.2 Ships operating in areas and during periods where ice accretion is likely to occur shall be:
- .1 designed to minimize the accretion of ice; and
- .2 equipped with such means for removing ice as the Administration may require; for example, electrical and pneumatic devices, and/or special tools such as axes or wooden clubs for removing ice from bulwarks, rails and erections.
- 4.3.1.3 Information on the icing allowance included in the stability calculations shall be given in the PWOM.
- 4.3.1.4 Ice accretion shall be monitored and appropriate measures taken to ensure that the ice accretion does not exceed the values given in the PWOM.
- 4.3.2.1 In order to comply with the functional requirements of paragraph 4.2.2, ships of categories A and B, constructed on or after 1 January 2017, shall be able to withstand flooding resulting from hull penetration due to ice impact. The residual stability following ice damage shall be such that the factor si, as defined in SOLAS regulations II-1/7-2.2 and II-1/7-2.3, is equal to one for all loading conditions used to calculate the attained subdivision index in SOLAS regulation II-1/7. However, for cargo ships that comply with subdivision and damage stability regulations in another instrument developed by the Organization, as provided by SOLAS regulation II-1/4.1, the residual stability criteria of that instrument shall be met for each loading condition.
- 4.3.2.2 The ice damage extents to be assumed when demonstrating compliance with paragraph 4.3.2.1 shall be such that:
- .1 the longitudinal extent is 4.5% of the upper ice waterline length if centred forward of the maximum breadth on the upper ice waterline, and 1.5% of upper ice waterline length otherwise, and shall be assumed at any longitudinal position along the ship's length;
- .2 the transverse penetration extent is 760 mm, measured normal to the shell over the full extent of the damage; and
- .3 the vertical extent is the lesser of 20% of the upper ice waterline draught or the longitudinal extent, and shall be assumed at any vertical position between the keel and 120% of the upper ice waterline draught.

ABS was heavily involved with and actively participated in the development of the Polar Code. Being so close to the code’s development enabled ABS to create and publish one of the first guidelines for industry a year before the Code came into force: IMO Polar Code Advisory.
To disseminate its knowledge, ABS offers training to ship owners/operators on the IMO Polar Code. This training provides owners an understanding of the requirements of the Code, how to manage its goal based standards structure, and how to effectively progress through the process up to and including issuance of the Polar Ship Certificate.
A key aspect of the Polar Code is contained in Chapter 1 Paragraph 1.5 – Operational Assessment, one of the cornerstones to the Polar Code’s application. An ABS Facilitated Operational Assessment, is a service offered by ABS where a formal HAZID is performed, climatic conditions and the ship’s capabilities and the Code’s requirements are closely examined to determine the required risk control measures. The outcomes of this assessment form the foundation to the ship specific Polar Waters Operational Manual.

WMO has various in situ observation programmes in polar waters.
The joint WMO-IOC Data Buoy Cooperation Panel (DBCP) established two action groups for the polar regions, the International Arctic Buoy Programme (IABP, 1991) and International Buoy Programme for Antarctic Buoys (IPAB, 1994) .
IABP focuses on Arctic Ocean and its marginal seas, excepting Exclusive Economic Zones, with expected resolution of 250km×25okm. It aims to provide meteorological and oceanographic data for real-time operational requirements and research purposes including support to the World Climate Research Programme (WCRP) and the World Weather Watch (WWW) Programme. As of June 2020, there were 223 buoys operational, thanks to high number of deployments in MOSAiC station. More details of IABP data, see http://iabp.apl.uw.edu/
IPAB (jointly WCRP/SCAR) investigates south of 55°S and that region of the Southern Ocean and Antarctic marginal seas within the maximum seasonal sea-ice extent, in 500km×500km grids. It is designed to provide meteorological and oceanographic data for real-time operational requirements and research purposes. In June 2020, there were 65 operational buoys, leaving most of Southern Ocean still sparsely sampled. More details of IPAB, see http://www.ipab.aq/.

Under the Ship Observations Team (SOT), mostly fast-moving Voluntary Observing Ships (VOS) regularly gather meteorological data (including sea ice) in the Arctic with manned or automated weather stations wherever the equipped ships navigate;
The Ship of Opportunity Programme (SOOP) deploys XBTs on mostly quarterly repeated lines which lead at least partly into the Arctic region and collect sea temperature profiles from the surface to 1000m.
Radiosondes (Automated Shipboard Aerological Programme-ASAP) for upper air soundings are only launched in this area as part of research ship activities. The latter operate inter alia in the Arctic region as part of the GO-SHIP repeat hydrography programme, with data collection from the surface to the seafloor of highest quality and full set of parameters. Some GO-SHIP lines are repeated every or at least every second year, but most of them (including the transpolar line on the map below) are sampled only once per decade. Neither in SOT nor GO-SHIP exists a particular working group or performance indicator with focus on polar matters.

Hyperlink 5: http://www.polarprediction.net
WMO is coordinating a Year of Polar Prediction (YOPP), starting in 2017, which will include a host of observing, modelling and educational activities. YOPP has the overarching goal to significantly improve our environmental prediction capabilities for the polar regions and beyond, on time scales from hours to seasons. Because of various teleconnections the poles influence weather and climate conditions in lower latitudes where hundreds of millions of people live. YOPP is intended to evaluate the improvement of weather and climate prediction worldwide with improved polar observational network. The connection to longer time scales is made through the World Climate Research Programme’s Polar Climate Predictability Initiative. The core period of YOPP entails intensive observation and modelling campaigns in both the Arctic and the Antarctic, scheduled from mid-2017 to mid-2019.

As part of the Polar Code implementation process, ABS requires that ship owners submit their PWOM to ABS for review (not approval). ABS reviews the manual to ensure that all hazards identified in the operational assessment are addressed. Some PWOMs have utilized Appendix 10 of the ABS Guide for Vessels Operating in Low Temperature Environments to estimate the ship’s operating temperatures. ABS recommends a closer and ship specific examination of the applicable hazards and ABS offers climatic hazard analysis services which includes air temperature and sea ice analysis.
Appendix II of the Polar Code contains an example Table of Contents for a PWOM, it is a starting point and leaves a significant content to be contemplated and completed by the ship owner. ABS’ Harsh Environment Technology Center is developing a template PWOM for ABS classed vessels seeking a Polar Ship Certificate.

International Chamber of Shipping (ICS)
Hyperlink: Guidelines for the Development of a Polar Water Operational ManualThe International Chamber for Shipping (ICS) and the Oil Companies International Marine Forum (OCIMF) jointly published this document in 2019. ICS and OCIMF members consider that how a ship is operated in Polar waters, and especially in ice, is a critical aspect for safe operations. The quality of the PWOM will have an impact on achieving safe operations. This document suplements the Polar Code and its Appendix II, which provides a model for a PWOM. The document states that while Appendix II is a useful starting point, ICS and OCIMF members have found that additional information is needed to develop a quality PWOM.
International Ice Charting Working Group
Hyperlink 1: http://www.bsis-ice.de/IcePortal/The Ice Logistics Portal (http://www.bsis-ice.de/IcePortal/) is operated by the German Hydrographic Service. This site provides convenient access to current ice charts produced by all of the national ice services in PDF and GIF formats as well as S-411 code for import to Electronic Navigation Chart System. Additionally, the site provides links to background ice information and coding standards. The ice information available on the Ice Logistics Portal is critical for voyage planning and navigation in Polar Regions. The information on the portal is not new but duplicates current ice chart data available on national ice service websites. It alleviates the need for mariners to be familiar with all of those sites and is more appropriate for the ASBPIF than an extensive listing of individual ice service websites.
Hyperlink 2: http://nsidc.org/noaa/iicwg/
For Arctic shipping, the website of the International Ice Charting Working Group (IICWG) most importantly provides contact information for all of the national ice services in the world, including 24/7 emergency access to ice information. Additionally, the site provides information about IICWG activities, summaries and presentations from annual IICWG meetings, documents on standards, and links to other ice information sites.

The worlds' oceans have been divided into 21 areas, called METAREA's, for the provision of marine products to shipping. The products displayed are issued by the National Meteorological Services (NMS) appointed as WWMIWS Issuing Services. METAREA Coordinators are assigned to coordinate provision of the marine services for each area. Canada, Norway, Russian Federation have responsibilities in the respective METAREAs in the Arctic polar waters.
