Petroleum and natural gas industries - Arctic operations - Ice management (ISO 35104:2018)
This document establishes the principles, specifies the requirements and provides guidance for ice management (IM) in arctic and cold regions, from the point of view of planning, engineering, implementation and documentation. Reference to arctic and cold regions in this document is deemed to include both the Arctic and other regions characterized by low ambient temperatures, sea ice, icebergs and icing conditions. These regions are often remote and lacking in marine and communications infrastructure.
Ice management to support the following in-ice activities and infrastructures are covered by this document:
— floating moored and/or dynamically positioned drilling vessels, coring vessels, production facilities and work-over vessels;
— construction and installation (includes trenching, dredging, pipe laying);
— tanker loading and other offloading operations;
— protecting subsea structures and equipment;
— seismic operations;
— oil spill response;
— bottom founded structures (fixed platforms and movable structures, including jack-ups).
This document also applies to mobilization, demobilization and construction support services, because these can be affected by ice conditions.
In view of the wide range of possible offshore operations in arctic and cold regions, this document provides guidelines, but does not present typical ice management plans for field operations.
This document does not provide requirements, recommendations or guidance pertaining to the design of structures, systems and components used in ice management, beyond the principles given. This document does not provide specific formulations for ice loads, which are covered by ISO 19906.
This document is not applicable to coastal port operations and to commercial trading vessels conducting transit or convoy operations.

Le présent document établit les principes, spécifie les exigences et fournit des recommandations pour la gestion des glaces (IM) dans les régions arctiques et froides, du point de vue de la planification, de l'ingénierie, de la mise en œuvre et de la documentation. Toute référence aux régions froides et arctiques faite dans le présent document renvoie à la fois à l'Arctique et à d'autres régions caractérisées par de basses températures ambiantes et par la présence de glace de mer, d'icebergs et de conditions propices à l'accrétion de la glace. Ces régions sont souvent éloignées et manquent d'infrastructures maritimes et de communication.
Le présent document traite de la gestion des glaces dans le cadre des activités et infrastructures suivantes en environnement de glace:
— navires de forage, navires de carottage, installations de production et navires de reconditionnement, ancrés et/ou à positionnement dynamique;
— construction et installation (y compris création de tranchées, nivellement, pose de tuyaux);
— chargement de pétroliers et autres opérations de déchargement;
— protection des structures et équipements sous-marins;
— opérations sismiques;
— intervention en cas de déversement de pétrole;
— structures sur fondations (plates-formes fixes et mobiles, y compris auto-élévatrices).
Le présent document s'applique également aux services de soutien à la mobilisation, à la démobilisation et à la construction, car ils peuvent être affectés par les conditions de glace.
Compte tenu de la grande diversité des opérations en mer possibles dans les régions arctiques et froides, le présent document fournit des lignes directrices mais ne présente aucun plan particulier pour la gestion des glaces dans le cadre des opérations sur site.
Le présent document ne fournit aucune exigence, préconisation ou recommandation en ce qui concerne la conception des structures, systèmes et composants utilisés dans la gestion des glaces, autrement que dans la limite des principes établis. Le présent document ne donne aucune formule spécifique pour les actions exercées par la glace, qui sont couvertes par l'ISO 19906.
Le présent document ne s'applique ni à l'exploitation de ports côtiers, ni aux navires de marchandises qui mènent des opérations de transit ou de convoyage.

Introduction
This document specifies requirements and recommendations applicable to ice management for oil and
gas operations in arctic and cold regions.
Ice management (IM) is defined as the sum of all activities, carried out with the objective to mitigate
hazardous situations by reducing or avoiding actions from any kind of ice (sea ice or glacial ice), and
includes:
— establishment of an understanding of the ice regime and potential ice hazards prior to the initiation
of operations;
— operational surveillance, including detection, tracking and forecasting;
— identification and evaluation of any physical threat to the operation;
— a working ice alert system and associated procedures;
— physical ice management by the supporting IM vessels, including ice breaking and/or iceberg
management;
— procedures associated with the safe avoidance of potentially hazardous ice;
— documentation of IM performance and revision of the IM system to ensure continuous improvement;
— relevant procedures associated with the safe shut-down of floating structures (moored or DP), both
active (move off and ice management) or semi passive (ice management, but no move off);
— relevant procedures associated with the safe shut-down of bottom-founded structures, both active
(with ice management and move-off capability), or passive (fixed with ice management).
This document describes performance requirements and recommendations to ensure timely
identification of ice hazards, their mitigation through ice management, and securement of the facility if
necessary.
This document is intended to ensure that ice management operations are planned, engineered,
integrated and implemented whenever needed. Performance requirements of an ice management
system can depend on the type of facility and the operations undertaken on the facility. Particular
emphasis is placed on ensuring adequate performance in circumstances where there is little prior
experience with a particular facility or in a particular geographical region.
This document consists of a normative part and an informative part. The normative part considers the
overall operations, hazards and possible counter measures, systems and procedures.
Annex A contains a HAZID workbook, which is to be used in conjunction with the relevant clauses when
preparing an ice management plan.
Annex B provides informative data, which supplements the normative part and is to be read in
conjunction with the main body of the document.
There are other International Standards which are also relevant to ice management, such as ISO 35101
for working environments and ISO 35106 for arctic and cold regions data requirements (for design
and operation). In addition, ISO 19900 specifies general principles for the design and assessment of
offshore structures subjected to known or foreseeable types of actions, applicable worldwide to
all types of offshore structures, including bottom-founded structures as well as floating structures,
and ISO 19906 specifies requirements and provides recommendations and guidance for the design,
construction, transportation, installation and removal of offshore structures, related to the activities of
the petroleum and natural gas industries in arctic and cold regions.

1 Scope
This document establishes the principles, specifies the requirements and provides guidance for
ice management (IM) in arctic and cold regions, from the point of view of planning, engineering,
implementation and documentation. Reference to arctic and cold regions in this document is deemed to
include both the Arctic and other regions characterized by low ambient temperatures, sea ice, icebergs
and icing conditions. These regions are often remote and lacking in marine and communications
infrastructure.
Ice management to support the following in-ice activities and infrastructures are covered by this
document:
— floating moored and/or dynamically positioned drilling vessels, coring vessels, production facilities
and work-over vessels;
— construction and installation (includes trenching, dredging, pipe laying);
— tanker loading and other offloading operations;
— protecting subsea structures and equipment;
— seismic operations;
— oil spill response;
— bottom founded structures (fixed platforms and movable structures, including jack-ups).
This document also applies to mobilization, demobilization and construction support services, because
these can be affected by ice conditions.
In view of the wide range of possible offshore operations in arctic and cold regions, this document
provides guidelines, but does not present typical ice management plans for field operations.
This document does not provide requirements, recommendations or guidance pertaining to the design
of structures, systems and components used in ice management, beyond the principles given. This
document does not provide specific formulations for ice loads, which are covered by ISO 19906.
This document is not applicable to coastal port operations and to commercial trading vessels conducting
transit or convoy operations.
