This document focusses on installations and asset elements within the upstream business category. Business categories and associated installations and plants/units, systems and equipment classes are used in line with ISO 14224:2016, Annex A.

The production loss categories given in Annex A are given at a high taxonomic level and supplements the reporting of failure and maintenance parameters as defined in ISO 14224:2016, Annex B.

ISO/TS 35105:2018 is intended to be used as a supplement to existing standards for steel structures where the particular operating conditions in Arctic regions are not sufficiently addressed.

ISO/TS 35105:2018 gives particular requirements to ensure safe operation with respect to the risk of brittle fracture at low temperatures. These requirements will affect the selection of material grade and design class as well as the technical delivery conditions for steel. They will also affect the fabrication requirements as well as testing and qualification requirements.

ISO/TS 35105:2018 also gives recommendations:

– to mitigate the operational and integrity aspects related to snow and ice accretion on topside structures;

– to take into account the particular Arctic operating conditions in corrosion assessments and requirements for corrosion protection systems;

– for particular operational requirements to ensure safe operation in Arctic regions.

The requirements in this document are applicable to any operating temperatures, but particular requirements related to de-rating (loss of strength) at high temperatures are not addressed. Limitations to the applicable minimum design temperature caused by the capability of the materials' low temperature performance can exist, but are not a limitation for the scope of this document.

As a practical guideline for the use of this document, low temperature is defined as lowest anticipated service temperature (LAST) below ?10 °C.

NOTE For determination of LAST, see 6.3.2.

Boxed text is original ISO 9001:2008 text unaltered and in its entirety. The petroleum, petrochemical, and natural gas industry sector-specific supplemental requirements are outside the boxes.

NOTE 1 Examples of standard industry use cases included in the secondary business process are included in Annex A along with standardized use case architecture.

This document gives:

— guidance for an architecture applicable to the oil and gas, petrochemical, power generation, public utilities and other asset-intensive industries;

— requirements for interoperability among systems of systems, systems (including hardware and software) and components included in the secondary business process of a plant, platform or facility at any given time;

— guidance on how these interoperability requirements are to be achieved and sustained in support of operations in the same plant, platform or facility;

— specifications enabling the specialization of a digital ecosystem concept for the requirements of the secondary business process in included industries;

— guidance to industry participants, including owner/operators and their product and services suppliers, to support their secondary business process requirements using products, which interoperate based on the specifications included in this document.

NOTE 2 This document is focused on interoperability requirements for systems which play roles in the secondary business process, including those in domains identified in Figure 7.

ISO/TS 15926-8:2011 provides rules for implementing the upper ontology specified by ISO 15926-2 and the template methodology specified by ISO 15926-7 into the RDF and OWL languages, including models for reference data as specified by ISO/TS 15926-3 and ISO/TS 15926-4, and for metadata.

The electronic files attached to ISO/TS 15926-8:2011 provide the OWL declarations, together with example instance data.

ISO/TS 15926-7:2011 provides a methodology for data integration of ontologies using mathematical first-order logic, which makes it independent of computer languages.

ISO/TS 15926-11:2015 conforms to the ISO 15926-2 data model and is appropriate for use with ISO 15926 reference data libraries
