Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

ISO 35106:2017(E)
Introduction
The series of documents on arctic operations (currently ISO 35101 to ISO 35106) addresses operational
requirements for use by the petroleum and natural gas industries in arctic and cold regions. Through
their application, the intention is to ensure human life safety and to minimize environmental damage. At
the same time, the series of documents is intended to provide wide latitude in the choice of operational
and design solutions without hindering innovation. Sound engineering judgment is, therefore, necessary
in the use of these documents.
This document is developed to provide a coherent and consistent definition of data requirements for
operations and designs in arctic and cold regions. With application to offshore, coastal and onshore
situations, the document focuses on meteorological, oceanographic, seabed and ice considerations. In
addition to the requirements of this document, the requirements of ISO 19901-1 for metocean data,
ISO 19906 for ice properties data and ISO 19901-4 and ISO 19901-8 for seabed data also apply.
For many geographical regions, physical environmental data are insufficient for rigorous statistical
determination of appropriate extreme and abnormal environmental actions and are insufficiently
detailed for the conduct of specialized operations. The determination of relevant operational and
design parameters therefore relies on the interpretation of the available data by subject matter experts,
together with an assessment of other meteorological, oceanographic, seabed and ice information. In
particular, uncertainties can arise from analyses based on limited data sets.
Annex A provides background to and guidance on the use of this document and it is intended to be read
in conjunction with the main body of this document. The clause numbering in Annex A is the same as in
the normative text to facilitate cross-referencing.

INTERNATIONAL STANDARD ISO 35106:2017(E)
Petroleum and natural gas industries — Arctic operations
— Metocean, ice, and seabed data
1 Scope
This document specifies requirements and provides recommendations and guidance for the collection,
analysis and presentation of relevant physical environmental data for activities of the petroleum and
natural gas industries in arctic and cold regions. Activities include design and operations, which involve
planning and actual execution.
Reference to arctic and cold regions in this document is deemed to include both the Arctic and other
locations characterized by low ambient temperatures and the presence or possibility of sea ice, icebergs,
shelf ice, glaciers, icing conditions, persistent snow cover, frozen surfaces of lakes and rivers, localized
and rapidly changing weather systems and/or permafrost.
This document outlines requirements for a range of different operations that have been or are presently
being undertaken and for existing design concepts. This document can also be used for other operations
and new design concepts in arctic and cold regions as long as it is recognized that all data requirements
are not necessarily addressed.
